@Mason Andres I really appreciate your reply. I got to the site through google and I'm waiting for the hacking stuff now. Looks like it's gonna take a while so I will get back to you later with my results.
I formerly ran the rapid prototype lab at Sulzer Orthopedics. Now Zimmer. I used to create complex bone models from CT and MRI data that was translated to .STL. The technology used individual sheets of heat sealed and laser cut paper. LOM...Laminate Object Manufacturing. These models allowed the surgeons to plan the repair and replacement of old or traumatized joints before ever cutting the patient. It was quite an advantage to be able to see the bone before cutting was involved. That technology was primitive compared to today's 3-D modeling capability.
I love that you show how much effort and times you tried to get the final result! - Not giving up its really the only way to get a successful outcome and of course some pretty cool tools!
I really don't understand exactly how this works. I'm 69 and this is so over my head. This is very interesting. The video is so well done. Your voice is so pleasing to listen too. You're a very intelligent young man. Thanks for sharing from Northern Illinois USA. Peace!!
Essentially it's triangulation. The program compares similarities from different photos, understands that what it's looking at are the same things, but in different positions. Then it understands (heavy simplification) from the changes in position where the camera ought to have been in relation to the object, and from there can reconstruct the geometry of the object. In theory it's simple, in reality it's far more complex 🙂
I’m watching videos to find out how to make myself into an action figure. It will be the greatest work produced by me. I may be holding a mirror to see a reflection of me as well. Thank you for the video.
"Why would you can bread?" Theatre props, that's why! Thanks for giving me such a good idea! I can now make stage props of food much faster and easier.
2:57 Tip for noobs. Small aperture means large number on your camera. e.g. F20 (think of the number as a fraction of the lens, so F1.2 [1/1.2] is a wider aperture than F5.6 [1/5.6]) Use A - Aperture priority settings on DSLR. Nice vid.
To avoid different light (exposing time, aperture) and different imaging scale (distance to the object, can cause also focus problems) and shaking problems, there is one magic key: don't move the camera - move the object! (if it's possible to move...) Get a used pottery wheel or any other "carousel" where You can set the Object on (to turn it) and put the camera on a tripod! Take videos with different camera hights. The resulting video quality will be much easier to process! (To make Your photo series even more precise, You can also put some angle marks around the outer rim of the wheel - and put a hand (vertical piece of wire or piece of cardboard, duct-taped on the bottom beneath the wheel) that indicates the scale - so You can turn Your object in precise angled steps!)
If you looked through the video you would've seen that I tried that method, and it's not without its issues. Firstly the algorithm in photogrammetry programs is heavily helped by the environment around the object you're scanning. By understanding the environment it can more easily understand the position of the camera, which in turn helps to understand the shape of your object. One way which can be more successful is using a greenscreen (like in Niels Provos' video I show a snippet of in my video), but if your object isn't sufficiently detailed that method will also be less than successful. I would rather recommend you take images with varying distance to your object. If there are parts with higher detail it can be very beneficial to take closeups of that area. The software should not have much issue stitching that together. Also the use of a tripod is entirely overkill as long as you work in good lighting so you can have shutter speeds on your camera fast enough to eliminate motion blur from shaking the camera. Finally I would not recommend using video for your scanning input. Even 4K video is lower in resolution (and more compressed, thus less detailed) than the photos even the simplest consumer digital cameras can take.

Haha, yeah, conservatively I think I spent 200 hours in total on this project, over the course of about six months. The editing and animations took much longer than I care to admit.
I am quite old and find technology overwhelming. I am in Canada and have always used the traditional methods of mould making for any sculptures I have created. It is an expensive and time consuming process. I usually cast into wax (for bronze), plastic, hydrocal, winterstone etc. I have been procrastinating about learning about 3D printing but decided to have a look at your video, which was enlightening and helpful. What I particularly enjoyed were the many trials and errors as you figured our your process. It was useful in being realistic about the process and its complexities. If I head into this world, I will get my tech savvy nephew to help me navigate and learn. I do not generally give thumbs up or comment but thought I would let you know that I enjoyed your video and found it useful. I also want that bread! Take care Switch and Lever and thank you.
You have some serious talent my friend. Had to give this video a like! You are a great teacher by the way. I learned soo much from this as I’m a novice to 3D printing
I will ask you the same question I've asked everyone who keep beating the mold making dead horse: How do you change the scale of a mold? The 3D printed head is roughly 1/5th scale of the original. The ring is scaled up by at least 25%. When you accomplish that using molds and vacuum forming I'd be all ears, until then it seems like the complaint of mold making is missing the entire point of the video.
Wow this video really made me want to get a 3d printer! The artistic possibilities are practically endless!! Just the failed scans alone would be amazing as desk decorations.
Great tips and details the process. I was trying to figure out how to get an copy of an existing option. Nice to know the option to just take picture and scan it is available, vs the 700+ scanner
COLMAP; free, updated regularly, maintained by a group dedicated to 3d work. Unlimited number of photos, photos can be from random cameras, very fast image processing. Output goes to Meshlab, also free, to get some clean up, make point-cloud into a 'skin'. Meshlab output to Blender. Edits, more filtering, export to STL. STL file to whatever Slicer you like, 3d-print. Captured the back curves of a Moto-e phone this way. 22 photos of paint-specked phone, 28 minutes in COLMAP to get point-cloud, 6 minutes in Meshlab to make OBJ file, 3 minutes Blender to scale and make STL file, 2 minutes in Cura to make G-CODE file. Photos to printing in less than an hour. Why scan an ancient Moto-e? No accessories I liked, so I made a 'skin-type' phone case. Unlike a Kinect or other structured light scanners, there is no effective size limit to image-only photogrammetry systems.
Sculpting and molding won't create a copy of what you have, it will make your interpretation of it. You could copy a document in a copy machine, scale it up and scale it down if need be, but you wouldn't call you rewriting that document by hand a copy. As for satisfying, that's for anyone to decide. If I had the artistic ability to do sculpting on this level I'm sure it would be very satisfying, but as it is I don't, so it would be an exercise in frustration more than anything, notwithstanding that I don't have the facilitates to cast silver.
Switch & Lever you are right, I have the prejudice of being an artists when I said that! For 1 to 1 scale mold copies I have had ver nice results with spinning the mold wrapped in a towel (centrifugal force pushes the metal down the mold, opening facing the spinner, only minimal force required). Another ancient method is sticking a half cut potato to the heated top of the mold immediately after spilling in the metal. I’ve done pretty smooth copies of plasticine sculptures (make sculpture, sink into it thin plastic foil dividers at strategic places where you want the 2 or 3 parts of your mold to open, then smudge plaster onto sculpture creating the mold..) with spilling soldering metal into them :P
Reflections are frequently a problem in photography and videography, so check out corresponding local forums and other such information sources for what people around you use as a "dulling spray" to remove them. Usually you'll find that hair care products are used, they are cheap, you can source them anytime and don't need to wait for shipping, and they can usually be washed off with warm water and soap, unlike paints which are permanent. Spraying a strong-hold hairspray from a larger distance and at an angle will make for a matte translucent surface as it sets in clumps, and blonde and highlight hair sprays are available too, pigmented in various colours.
I was just wondering about the paint used on the head. It was a nice method, but as the goal was to copy a "precious object", I doubt you'd want to use any permanent substance on it. Your suggestion seems very interesting.
Yeah, I learned about this about 20 years ago while working on a photo shoot. They were getting glare off chrome baskets and saw the guy walking around with a can of hair spray. It costs about 1/4 what the "official" dulling spray does and is available just about everywhere. It does just wipe off with warm water/cloth.
This is so great! Thanks for sharing, I know that one day I'll need to scan something and print it on my 3d printer, this information would've help alot.
Instead of spraying paint onto the surface, try this: 1. Mix 100g of corn starch with 150-200ml of water for white contrast paint 2. Mix 50g of corn starch with 50g of coal powder (coconut coal powder is cheap on Amazon) and 150-200ml of water for grey/black contrast paint 3. Apply with a €2 car sponge, tap and wipe around a bit to create swirls and patterns It's cheap as hell (€2 sponge + €5 each for 500g starch and coal) and doesn't destroy the object (I've tried with things like spray chalk before but sometimes the solvent attacks the object's surface and causes chalk/paint to permanently stick). When I shoot in good lighting and input photos at ~3k * 2k res, Meshroom detects well over 100k features in each of them and the scans are extremely accurate.
Gives a whole new subset of use-cases for camera's expensive and cheap. And skullrings definitely aren't tacky. Yours has an awesome story connected to it. Cheers man, thanks for sharing! Have a few coffee's on me!
@@RayRand It's on their github github.com/alicevision/meshroom/releases/tag/v2018.1.0 I've used it a few times now and if you get the images right its the bomb
There are rings like that on Ebay. Small silver with ruby eyes were popular among sixties fans. I got mine facing eye socket forward on a shelf in my den. Precious and cute, but so creepy!
PREVIOUS PLACE OF EMPLOYMENT I "FOUND" EQUIPMENT IN A CORNER *Translated* - My boss fired me so I took equipment that nobody would notice, uploads video with adds and makes money to cover the cost of getting fired (Love you 🥰🥰:)) - great video
Cool story bro, that sounds much more logical than that I recorded a video which sat around on my harddrive for months during which time I changed jobs. 🤔
Fantastic tutorial! I am a neophyte with zero 3D experience and a huge interest in learning about it. Until I found this video I was totally ignorant of how to create files. None of the videos about or instructions for 3D printers discuss files other than mentioning different softwares available. This step-by-step guide was a giant step for me towards understanding the process. I particularly appreciate the advice about spray painting the model in contrasting colors. I can't wait to try this!
I liked your video very much. The details of the struggles to perfect 3D printing/reproductions has been a trial and error only a few understand. There were times when you would think it's not even possible but every little advance no matter how insignificant promised a perfect end result somewhere in it's future. From idea to tangible reality. Thanks for sharing! :-)
another rule of thumb for photogrammetry is that the photos overlap each other by 60%, source is that i work with drone photos of big areas for surveying, we use the software agisoft, there is a free version of it but you can export your work with it.
Agisoft is good, but I don't know if I'm using it wrong since all my results from it are much worse than 3DF Zephyr, when using the same source material. The results tend to be more noisy and more fragmented.
Im kinda new to agisoft, but i would recommend the 60% overlapped photos, also something i learned is that pixels is everything and white pixels are basically dead ones. So the optimal camera settings is kinda counter intuitive, you should have as low ISO setting as you can, fast shutter-speed. Also using a relatively narrow lens also helps (18-24mm).
Very informative... and beautifully done. Especially liked your coverage of the failed attempts and process evolution. Most don't cover that and this is so vitally important for understanding. TY !!
I have this EXACT mannequin head, and I, unfortunately, painted it matte black and splatted it with white paint to make it scannable... and DAMN it came out SO good.
Somehow I stumbled upon this video after I pulled out my XBox 360 Kinect to see if it can be used as a webcam. Now I'm going to waste the next two years of my life trying to get a 3D model of my son's head from a 3D printer that I don't have. Thanks a lot!
17:51 "That's really all there is to it". Months of work, thousands of photos, learning a dozen software tools, painting, stickers, modeling, printing, and purchasing (or home-brewing) several laser scanners. But you got a plastic head and a ring. Hmmm... at least it was free! The tip to paint it in a non-reflective coat, and spackle it with white and black paint is great.
Months of work? Naw, days of work, literally several days of work! Also never bought a laser scanner, I even specifically say this in the video. Though, you're kind of missing the point, this is what I made with it, to be able to share my tips and tricks on how to do photogrammetry and 3d scanning successfully, what you choose to do with it when you're done is totally up to you. If you think the end point was to make a small head and a ring and not to actually acquire the knowledge and learning in the process then I could see your confusion.
@@SwitchAndLever I actually do really appreciate that you did all this; I would have had to repeat it to learn what I did in your 18 min video. But I can say it would have taken me weeks. I was trying to capture the humor of "That's all there is to it". Seems like a lot to me! One of the best things I learned is it's not hard to order a metal version of a 3D object online. So I don't need to buy a metal 3D printer!
Great video, its been 2 years, since it was made, would you do a follow up video with updated new developments in both scaning and 3D printing hardware software, please?
I have recently started making rc truck vaccum molding body and this is a great way for mr to cut some major working time on making 3d model. Thank you sir!👍💪👌
@@christopherbradbury9124 hi. Thanks to show interest in my project. Ill make a short story: yes it work, but not on a scale I can sell them. The production cost is hight and at the end the result is not that great. Its easy to make a body with a thin plastic, but with a thicker plastics it's not the same. I dont have enought experience right now. But its going foward even with that covid19 virus. I also dont feel confortable salling the same body as traxxas. I also want to add that I started this project last September... perfections needs time. Thank you for your comments. Stay safe👍
A way better software than those is "meshroom", it's completely free, doesn't have any limitation and tells you where you need more pictures. My first test was the exact SAME piece, it also gives coloured texture.
Oh my...! I'd never have thought of 3D printing my precious items!! Holy crap, what a fantastic idea, I'm going to do it just like you did your ring for some of my (cheap but I love them) jewelry, what a great video! I love this. Really would never have thought of this, this is brilliant. And your video's quality is amazing, the explanations, demonstrations, errors encountered and WHY... Simply fantastic. Excellent job, will be referring to this video again! Thanks for your efforts and for sharing!!!
Did you actually watch the video to completion? You don't need a 3D printer, you can order 3D prints from a wide variety of different online services, among them my favorite Shapeways. It helps if you have a 3D printer, but it's in no way shape or form required.
You can try also to place the object (not too heavy) in a battery operated Motorized Display Rotate Stand ...is a very cheap option to get online. One camera, one display base.
Wow I didn't know this was possible. Thanks for the education. Also good to see that is not all just an instant success. It makes it easier to cope with my own trials.
Intuitively, I thought putting the head on a turntable and turning it while keeping the camera still on a tripod would give the best result. But this was not the case?
The software relies on matching points between images. If the background stays the same the software gets confused. Also the lighting on the head will constantly change when rotating it, unless you're working in very even lighting, making matching harder.
Switch and Lever Maybe if you were to try using a 'green screen' like they use in CGI effects and before entering each photo into the phot matching software you were to do something like change the background color of the 'green screen'
Yes, that is what Niels Provos did in the video I mentioned, and I basically did the same but didn't use a green screen when I masked out and replaced the background with pure black. Didn't help me though, even though it is a usable method. You just have to make sure your lighting is even.
Switch & Lever I was kind of meaning more like actually in a separate post- photography operation, basically using the 'green screen' as a background, but in something like Photoshop editing the color into something like blue, then green, then grey, then yellow or something like that to prevent the software from getting confused by tricking it into only focusing on the image you want to scan
SFM. Structure From Movement. The idea that changes in image frame by frame reveals camera motion and ultimately the object point-cloud, or Structure. Turntable can work well, but you have to make sure the model is the ONLY thing the camera can see. Two ways to do this: backdrops/lighting when taking photos to exclude the background or crop your photos in post production to remove backgrounds. The software will try to match points from one image to the next; if it can 'see' lots of background NOT moving when the turntable runs, then the software assumes the turning bit to be noise. Many softwares out there have a 'tell me three times' thing going on when it comes to images. Take your pictures, but if two of them are something you don't want in your scan? No biggee! it takes three images with good correlation to make 'real points' in these systems. Biggest hurdle in this work is in the camera: JPG compression. Take your shots, but look at the images in extreme close-up. Do you still have pixels of good color & shape? Or is it sloppy colorful compression noise? Image quality is your biggest factor in success.
I tried several software products, including 3DF Zephyr and found that this was the best. I got the best result from the first try and it was the easiest to use. And it is also free. Installing Autodesk Recap is a nightmare..
You should have a white or contrasting background in each picture you take. This should be as obvious as depth of field and lighting. You can achieve this very simply by using a piece of foam board that you rotate around the object as you walk around taking each picture. For what it's worth, it will provide faster and much more accurate results than what is happening here.
For the consumer not all that much have changed in this field in the last few years. On the research level there are a lot of exciting stuff going on though, involving neural networks and machine learning, but we have yet to see any of this make it into a product for doing proper 3d scanning I'm afraid.
Tacky is only in the opinions of others and is none of my business what other people think of me. Just like it’s none of your business what other people think about you. Best advice I’ve ever heard.

Meshroom is the new big dog. No configuration at all, just drop the images and you're good. The scans are far superior than any other programs too!

Wow this video really made me want to get a 3d printer! The artistic possibilities are practically endless!! Just the failed scans alone would be amazing as desk decorations.
Did you get one?
Great tips and details the process. I was trying to figure out how to get an copy of an existing option. Nice to know the option to just take picture and scan it is available, vs the 700+ scanner
COLMAP; free, updated regularly, maintained by a group dedicated to 3d work.
Unlimited number of photos, photos can be from random cameras, very fast image processing.
Output goes to Meshlab, also free, to get some clean up, make point-cloud into a 'skin'.
Meshlab output to Blender. Edits, more filtering, export to STL.
STL file to whatever Slicer you like, 3d-print.
Captured the back curves of a Moto-e phone this way.
22 photos of paint-specked phone, 28 minutes in COLMAP to get point-cloud, 6 minutes in Meshlab to make OBJ file, 3 minutes Blender to scale and make STL file, 2 minutes in Cura to make G-CODE file.
Photos to printing in less than an hour.
Why scan an ancient Moto-e? No accessories I liked, so I made a 'skin-type' phone case.
Unlike a Kinect or other structured light scanners, there is no effective size limit to image-only photogrammetry systems.
do you know of a good workflow demo video using this method?

Those bad scans on the mannequin head looked like some deep artistic reflection of modern man. Lol
Finally, sculpting and molding may be quicker and more exciting and satisfying than all this ?
Sculpting and molding won't create a copy of what you have, it will make your interpretation of it. You could copy a document in a copy machine, scale it up and scale it down if need be, but you wouldn't call you rewriting that document by hand a copy.
As for satisfying, that's for anyone to decide. If I had the artistic ability to do sculpting on this level I'm sure it would be very satisfying, but as it is I don't, so it would be an exercise in frustration more than anything, notwithstanding that I don't have the facilitates to cast silver.
Switch & Lever you are right, I have the prejudice of being an artists when I said that! For 1 to 1 scale mold copies I have had ver nice results with spinning the mold wrapped in a towel (centrifugal force pushes the metal down the mold, opening facing the spinner, only minimal force required). Another ancient method is sticking a half cut potato to the heated top of the mold immediately after spilling in the metal. I’ve done pretty smooth copies of plasticine sculptures (make sculpture, sink into it thin plastic foil dividers at strategic places where you want the 2 or 3 parts of your mold to open, then smudge plaster onto sculpture creating the mold..) with spilling soldering metal into them :P
Reflections are frequently a problem in photography and videography, so check out corresponding local forums and other such information sources for what people around you use as a "dulling spray" to remove them. Usually you'll find that hair care products are used, they are cheap, you can source them anytime and don't need to wait for shipping, and they can usually be washed off with warm water and soap, unlike paints which are permanent. Spraying a strong-hold hairspray from a larger distance and at an angle will make for a matte translucent surface as it sets in clumps, and blonde and highlight hair sprays are available too, pigmented in various colours.
I was just wondering about the paint used on the head. It was a nice method, but as the goal was to copy a "precious object", I doubt you'd want to use any permanent substance on it.
Your suggestion seems very interesting.
Yeah, I learned about this about 20 years ago while working on a photo shoot. They were getting glare off chrome baskets and saw the guy walking around with a can of hair spray. It costs about 1/4 what the "official" dulling spray does and is available just about everywhere. It does just wipe off with warm water/cloth.
Stumbled on this video by accident, so glad I did.
This is so great! Thanks for sharing, I know that one day I'll need to scan something and print it on my 3d printer, this information would've help alot.
there have been some quite interesting, and spooky, animations done using this technique....
Instead of spraying paint onto the surface, try this:
1. Mix 100g of corn starch with 150-200ml of water for white contrast paint
2. Mix 50g of corn starch with 50g of coal powder (coconut coal powder is cheap on Amazon) and 150-200ml of water for grey/black contrast paint
3. Apply with a €2 car sponge, tap and wipe around a bit to create swirls and patterns
It's cheap as hell (€2 sponge + €5 each for 500g starch and coal) and doesn't destroy the object (I've tried with things like spray chalk before but sometimes the solvent attacks the object's surface and causes chalk/paint to permanently stick).
When I shoot in good lighting and input photos at ~3k * 2k res, Meshroom detects well over 100k features in each of them and the scans are extremely accurate.
Gives a whole new subset of use-cases for camera's expensive and cheap. And skullrings definitely aren't tacky. Yours has an awesome story connected to it.
Cheers man, thanks for sharing! Have a few coffee's on me!

Hi
Since this video got released, Meshroom is probably the best bet for free photogrammetry
All I see on their site is downloads of 3d models, I don't see any actual software.
@@RayRand It's on their github github.com/alicevision/meshroom/releases/tag/v2018.1.0 I've used it a few times now and if you get the images right its the bomb
There are rings like that on Ebay. Small silver with ruby eyes were popular among sixties fans. I got mine facing eye socket forward on a shelf in my den. Precious and cute, but so creepy!
PREVIOUS PLACE OF EMPLOYMENT I "FOUND" EQUIPMENT IN A CORNER
*Translated* - My boss fired me so I took equipment that nobody would notice, uploads video with adds and makes money to cover the cost of getting fired
(Love you 🥰🥰:)) - great video
Cool story bro, that sounds much more logical than that I recorded a video which sat around on my harddrive for months during which time I changed jobs. 🤔
Fun fact: one of those errors is how they got the album cover art for A rush of blood to the head.
Nice video friend! I noticed the Fisher-Price camera and the spaghetti printer. The metal printing by Shapeways is awesome! Going to try it for sure.
Fantastic tutorial! I am a neophyte with zero 3D experience and a huge interest in learning about it. Until I found this video I was totally ignorant of how to create files. None of the videos about or instructions for 3D printers discuss files other than mentioning different softwares available. This step-by-step guide was a giant step for me towards understanding the process. I particularly appreciate the advice about spray painting the model in contrasting colors. I can't wait to try this!
I liked your video very much. The details of the struggles to perfect 3D printing/reproductions has been a trial and error only a few understand. There were times when you would think it's not even possible but every little advance no matter how insignificant promised a perfect end result somewhere in it's future. From idea to tangible reality. Thanks for sharing! :-)
That came out beautifully!!! I used to wear a skull ring every day, as well! Not the same one, but I do like the one you've made a great deal!
Love the sense of humor. Even tough it's gluten free!
another rule of thumb for photogrammetry is that the photos overlap each other by 60%, source is that i work with drone photos of big areas for surveying, we use the software agisoft, there is a free version of it but you can export your work with it.
Agisoft is good, but I don't know if I'm using it wrong since all my results from it are much worse than 3DF Zephyr, when using the same source material. The results tend to be more noisy and more fragmented.
Im kinda new to agisoft, but i would recommend the 60% overlapped photos, also something i learned is that pixels is everything and white pixels are basically dead ones. So the optimal camera settings is kinda counter intuitive, you should have as low ISO setting as you can, fast shutter-speed. Also using a relatively narrow lens also helps (18-24mm).
@@Jellooze Thanks for the tips from a proper photographic perspective!
Wow, you are excellent. Good teaching style - you are smart, you get to the point, and explain clearly. Thanks
Very informative... and beautifully done. Especially liked your coverage of the failed attempts and process evolution. Most don't cover that and this is so vitally important for understanding. TY !!
So true, wish more tutorials had this approach (not only showing when everything turns out perfect).
Great intro and presentation on 3 - D printing. Also useful for those interested in entry level 3 - D printers.
@@SwitchAndLever Sorry. Fixed my comment and thanks for letting me know it was weird! Happy summer!
I have this EXACT mannequin head, and I, unfortunately, painted it matte black and splatted it with white paint to make it scannable... and DAMN it came out SO good.
Somehow I stumbled upon this video after I pulled out my XBox 360 Kinect to see if it can be used as a webcam. Now I'm going to waste the next two years of my life trying to get a 3D model of my son's head from a 3D printer that I don't have. Thanks a lot!
You did an excellent job with this video. Thanks!
Nice! Phantom got his ring back! Thanks!
17:51 "That's really all there is to it". Months of work, thousands of photos, learning a dozen software tools, painting, stickers, modeling, printing, and purchasing (or home-brewing) several laser scanners. But you got a plastic head and a ring. Hmmm... at least it was free!
The tip to paint it in a non-reflective coat, and spackle it with white and black paint is great.
Months of work? Naw, days of work, literally several days of work! Also never bought a laser scanner, I even specifically say this in the video. Though, you're kind of missing the point, this is what I made with it, to be able to share my tips and tricks on how to do photogrammetry and 3d scanning successfully, what you choose to do with it when you're done is totally up to you. If you think the end point was to make a small head and a ring and not to actually acquire the knowledge and learning in the process then I could see your confusion.
@@SwitchAndLever I actually do really appreciate that you did all this; I would have had to repeat it to learn what I did in your 18 min video. But I can say it would have taken me weeks. I was trying to capture the humor of "That's all there is to it". Seems like a lot to me!
One of the best things I learned is it's not hard to order a metal version of a 3D object online. So I don't need to buy a metal 3D printer!
the best video of 3d scanning of all time on youtube! thank you very much!
Great video, its been 2 years, since it was made, would you do a follow up video with updated new developments in both scaning and 3D printing hardware software, please?
I love this age,and seeing so much creative people on RUclips 😁👍 it has become a hobby which inspires me when i make music. Stay creative!
I have recently started making rc truck vaccum molding body and this is a great way for mr to cut some major working time on making 3d model. Thank you sir!👍💪👌
@@christopherbradbury9124 hi. Thanks to show interest in my project.
Ill make a short story: yes it work, but not on a scale I can sell them. The production cost is hight and at the end the result is not that great. Its easy to make a body with a thin plastic, but with a thicker plastics it's not the same. I dont have enought experience right now. But its going foward even with that covid19 virus.
I also dont feel confortable salling the same body as traxxas.
I also want to add that I started this project last September... perfections needs time.
Thank you for your comments.
Stay safe👍
Very good and useful video ! Next I'm going to have to learn to turn my Kinnect into a 3d scanner...
Love your humor - was devastated not to have won the printed bread 🤣
The printed bread surely does look amazing and also the rest of the video looks great! Thanks.
Cheers, I appreciate it!
You sir got yourself a new subscriber. Also sticking a good flash light to the camera would solve the shadow problem.
The way you teach really fits my head. Thanks dude.
Interesting to bring together GIS / Photogrammetry with 3D printing. New to the later and wanted to say thanks for the information shared.
A way better software than those is "meshroom", it's completely free, doesn't have any limitation and tells you where you need more pictures. My first test was the exact SAME piece, it also gives coloured texture.
Finally a video how to do this . Thank you
Oh my...! I'd never have thought of 3D printing my precious items!! Holy crap, what a fantastic idea, I'm going to do it just like you did your ring for some of my (cheap but I love them) jewelry, what a great video! I love this. Really would never have thought of this, this is brilliant. And your video's quality is amazing, the explanations, demonstrations, errors encountered and WHY... Simply fantastic. Excellent job, will be referring to this video again! Thanks for your efforts and for sharing!!!
Good Video! Really good Idea with the dots on the objects! Also good to see a comparison between the programms out there!
Did you actually watch the video to completion? You don't need a 3D printer, you can order 3D prints from a wide variety of different online services, among them my favorite Shapeways. It helps if you have a 3D printer, but it's in no way shape or form required.
@@SwitchAndLever Yeah, im sorry, yesterday was a bit of an emotional day for me, im sorry c: Im actually going to change the comment xD
Switch & Lever bad acne is also good if your doing a face or buttocks
The small bread is awesome :)
Follow on instagram and enter the raffle, it could be yours! :)
You can try also to place the object (not too heavy) in a battery operated Motorized Display Rotate Stand ...is a very cheap option to get online. One camera, one display base.
I address this in the video and why it’s not necessarily a good idea to spin the object rather than move the camera.
Skull rings are cool ! Great job. Lots of great info too.
This is the most informative video I have seen on this subject
Thank you for this gem of educational content.
Im just a beginner to 3D printing and could learn alot from this video. Thx alot
Wow I didn't know this was possible. Thanks for the education. Also good to see that is not all just an instant success. It makes it easier to cope with my own trials.
Just added to the "Best Videos" playlist, awesome video :)
Intuitively, I thought putting the head on a turntable and turning it while keeping the camera still on a tripod would give the best result. But this was not the case?
The software relies on matching points between images. If the background stays the same the software gets confused. Also the lighting on the head will constantly change when rotating it, unless you're working in very even lighting, making matching harder.
Switch and Lever Maybe if you were to try using a 'green screen' like they use in CGI effects and before entering each photo into the phot matching software you were to do something like change the background color of the 'green screen'
Yes, that is what Niels Provos did in the video I mentioned, and I basically did the same but didn't use a green screen when I masked out and replaced the background with pure black. Didn't help me though, even though it is a usable method. You just have to make sure your lighting is even.
Switch & Lever I was kind of meaning more like actually in a separate post- photography operation, basically using the 'green screen' as a background, but in something like Photoshop editing the color into something like blue, then green, then grey, then yellow or something like that to prevent the software from getting confused by tricking it into only focusing on the image you want to scan
SFM. Structure From Movement. The idea that changes in image frame by frame reveals camera motion and ultimately the object point-cloud, or Structure.
Turntable can work well, but you have to make sure the model is the ONLY thing the camera can see.
Two ways to do this: backdrops/lighting when taking photos to exclude the background or crop your photos in post production to remove backgrounds.
The software will try to match points from one image to the next; if it can 'see' lots of background NOT moving when the turntable runs, then the software assumes the turning bit to be noise.
Many softwares out there have a 'tell me three times' thing going on when it comes to images.
Take your pictures, but if two of them are something you don't want in your scan?
No biggee! it takes three images with good correlation to make 'real points' in these systems.
Biggest hurdle in this work is in the camera: JPG compression.
Take your shots, but look at the images in extreme close-up.
Do you still have pixels of good color & shape? Or is it sloppy colorful compression noise?
Image quality is your biggest factor in success.
Ive learned so much from this video. Much more than what ive initially expected from the title. THANK YOU.
You are equally as informative as you are entertaining. Subscribed!
I tried several software products, including 3DF Zephyr and found that this was the best. I got the best result from the first try and it was the easiest to use. And it is also free. Installing Autodesk Recap is a nightmare..
free for 14 days though :(
I would love if you showed how to take the 3D model to the 3D printer?
Informative and entertaining as well. Love the video narration style.
You should have a white or contrasting background in each picture you take. This should be as obvious as depth of field and lighting.
You can achieve this very simply by using a piece of foam board that you rotate around the object as you walk around taking each picture.
For what it's worth, it will provide faster and much more accurate results than what is happening here.
This looks difficult. Fun video.
Thanks for info, 3DF Zephyr confirmed to be easy, free and good :-)
This man, I love him
I had that ring!!! Very nice video!
Loads of information! Amazing video!
Wow great info and detail. Thank you. Love the story as well.
Very helpful for my current projects. Keep it up!
I just saw your video. Holy Sh!t, this is an awesome video. It answered, all my questions. Thank you so much. I’m watching the rest of them.
I’ve used LiDAR scanners like faro for scanning sets and locations for movies and visual effects. They are great tools but it takes time…
Great material. Although this video needs a follow up, a lot of things can change in 3 years
For the consumer not all that much have changed in this field in the last few years. On the research level there are a lot of exciting stuff going on though, involving neural networks and machine learning, but we have yet to see any of this make it into a product for doing proper 3d scanning I'm afraid.
