Review: Zeiss T Scan Hawk 2 Handheld Laser 3D Scanner
After using my Zeiss T-Scan Hawk 2 for about 6 months, it is time to make a review video for it. Overall I've been pretty happy with it, but it does have its issues.

Scan to CAD Workflow: Recreating Keycaps Using DezignWorks + Solidworks 2022
Просмотров 9862 года назад
Unfortunately for me, my pet black-capped conure takes great pleasure in destroying my laptop's keys. In this video, I undertake the task of 3D scanning keycaps and reverse engineering replacements. After receiving new 3D-printed ones from Protolabs, my laptop now has a full set of keys again! To accomplish this, I first scanned the parts using our Steinbichler Comet L3D structured light scanne...
Scan Spray Showdown: What is the Best Coating for 3D Scanning?
Просмотров 21 тыс.2 года назад
Structured light 3D scanning is an amazing tool for inspection and reverse engineering, but it does have its limits. One of the biggest hurdles you can encounter during a scan is the part's surface. If it's too reflective, transparent, or dark, your scan data probably won't look so good. In these cases, it's best to apply a coating to improve your results. But which coating should you use? It t...

How to Check the Accuracy of your 3D Scanner
Просмотров 3,3 тыс.2 года назад
How accurate is your 3D scanner? If you've never checked, it is definitely worth your time to find out! Whether you have a cheap scanner like a Revpoint Pop, prosumer system like an Artec Leo, or a high-end industrial scanner like a Creaform Metrascan3D, knowing it's accuracy is extremely important for metrology and reverse engineering projects. We also discuss some calibration standards you ca...
Repairing a Broken Olympus Mju by Reverse Engineering with FreeCAD
Просмотров 2,4 тыс.2 года назад
Reverse engineering is a really cool application of 3D scanning! It can be used to replicate parts that cannot be purchased so that older products can be repaired. It can also be used to customize parts. Even if the part is broken, the part's scan data can still be used to recreate a CAD model of the entire part. This can be accomplished using free tools like Gom Inspect and FreeCAD. Once the C...
Structured Light 3D Scanning a Nintendo Gamecube Controller
Просмотров 5002 года назад
To demonstrate the structured light 3D scanning process, we scanned the top panel of Nintendo's Wavebird wireless controller. Your process will be similar even if you are using a white light 3D scanner, or any scanning system from Gom.

What are you using to hold your scale bar, when doing satellite mode. Do you have a link for it? Thanks!
I use Noga's products (vacuum mounts, magnetic bases, arms, etc.) for holding my scale bars in combination with some Neewer/Smallrig clamps. I think I had to get some thread adapters for them to play nicely with each other, though.
Also it seems that the foot spray contains Zinc Oxide, which could potentially be less toxic to humans than Titanium.
Tempura is seafood coated in thin batter and deep fried. Tempera is pigment mixed with egg yolk.
You can coat the calibration Parts with some opaque powder to prevent the lasers from entering the Surface 👍
Yes, that is a good point. I'm planning to purchase some new steel ball bars for this scanner. I don't want to coat my existing matte ball bars because I'm afraid the coating won't wash out very well from the porous surface and also because it is hard to gage how much coating has been applied to an already matte white surface.
@@sentinel3dscanning You might try some dry hair shampoo from a spray can. It's more or less rice starch and water soluble, It works great for the cheaper 3d scanner out ther.
hawk tui?
Beat me to it.
Yup!
A couple more things I thought of after recording this video: 1. I love that the object you are scanning doesn't need to be stationary during the scanning process - you can hang a part from the ceiling and scan it while it spins around on a string/rope, as long as target stickers are on the part. I know this isn't specific to this scanner, but it is cool nonetheless. 2. Automatically finding common reference points (a.k.a. target stickers) on two overlapping scans is really nice, but the GUI is annoying to use when unselecting individual points because it scrolls back to the top of the list. I also found a cool example of a Milwaukee Packout setup specifically for 3D scanning here: instagram.com/kaizen_inserts/p/CsQs50qLPYu/?img_index=1
ATTBLIME coats a very thin layer between 3 microns to 6 microns depending on the spray. Recommended for highly accurate 3D scans.
What I missed in the video are the existing and quite common standards for accuracy checking of 3d scanners like the VDI 2634 sheet 2 (single scan data) and sheet 3 (merged data).
I do see VDI 2634 and ISO 10360 being referenced more often in accuracy specifications these days. I haven't read these standards yet, so I'm not qualified to comment on them. I can say that my own accuracy tests performed on my Zeiss T-Scan Hawk 2 were slightly outside of Zeiss' 10360-based accuracy specification, so it is probably a good idea to reference your own tests rather than completely relying on a manufacturer's specification when explaining accuracies to your stakeholders.
Apparently, per the SDS, Dr Scholls foot power is butane, ethanol and talcum power. Talcum Powder has a refraction index of approximately 1.5 and Titanium Dioxide is approximately 2.5 considering talc is almost exactly half the cost kg per kg and I have talc on hand I will have to experiment with some denatured alcohol solutions and some photogrammetry projects i have going on. Thank you this has been informative. FYI denatured alcohol is primarily ethanol alcohol with methanol as a poison to eliminate alcohol taxes.
How you apply this solition intou your objects?
@@que_dijo just buy the foot powder spray or talc per the pound and use a rapidly evaporating solvent like isopropyl, acetone, or denatured alcohol so it could be used in a spray bottle or paint gun. The uneven texture gives scanners something to reference and give cleaner scans or photogamatry.
So i have a plastic model jetski i am trying to scan and its too shiny. I tried foot powder, and i even sprayed it with grey plasti-dip. I have to of these models, one is yellow top and yellow bottom, the other is white top and yellow bottom. I really dont want to damage these as they are rare but i want to male 3d printed replicas. I am using a Creality Ferret Pro scanner. Any suggestions? That AEsub spray is spendy, should i try that?
Aesub Orange is probably the best way to go if you want to reduce damage. In my experience, Aesub Blue evaporates too quickly and goes on rougher. It will be pricy, but it will be safe. On something as big as a jetski, you will probably need several cans.
@@sentinel3dscanningi sent you an email from your website
@sentinel3dscanning its a toy model its only about 10inches long.
Have you tried plasti dip paint that you can peel off afterwards
for plastidip (any rubberized coating) to "peel" off you would have to apply it heavily, which will significantly alter the actual surface of the object being scanned, if it's something that remotely requires any sort of accuracy, it's not going to work.
This was an extensive video, measuring even the surface of the spray. Although as mentioned Foot Spray is great if you don't mind the clean up otherwise the spray is the best solution.
Thanks for putting this video together. It's really going to help me going forwards.
Great information....
12 years in metrology and after ton of "lets verify this dimension with caliper" videos, i really admire what you showed here. If you have all of these resources than you for sure can do Linearity with your "verification" artifact in combination with different lenses. Uncertainty is more part of "calibration" company. And there not much that you can do here... But still. We used GOM only for plastic and cold formed metal sheet objects. What you mentioned is absolutely true, they are hiding uncertainty details. If you spent 50k or more on fancy scanner that you expect a nice quality scanning, which in fact can be done with 5-10k scanners. Those scanners are not made for precise measurements, if you wanna go with precision, than CMM is a way to go. For field measurements i would recommend laser tracker.
4:32 Whaaat
I need to place reflective dots on the black plastic object I am trying to scan. I find the foot powder comes off to easy in handling.
Man this channel is so underrated
I use Zinc Oxide from Amazon mixed with 99 percent IPA. It is very white. But perhaps Titanium Dioxide is even better.
Thank you for doing all of this work. Amazing.
Nice! What song is playing as you make the repair?
Tutorial on aligning meshes with GOM like you demonstrated in the video would be awesome!
Subscribed 👍
Excellent, thank you. Now to go buy some foot spray 😅
What is the ratio of Titanium Dioxide powder to denatured alcohol that you used?
Any possibility of you doing the plastic gears on the bottom?
Hi, is there any chance you could make the file available for 3d printing. I have a MJU that id like to repair
I added a link to the description where you can download the .stp file for printing. Make sure to choose a high-resolution printing method.
Just go to an NDT supply house and buy some dye developer. 5 year supply for like 20 bucks.
Just be more specific!
I wish. A single can of that is $18 to $30. That will last for a few objects as long as it is not large like a car. Also virtually doesn’t exist. I see some on eBay.
Thank you, great and useful work.
Magnaflux spot check developer works pretty well
This is the most over engineered video on foot powder ever and I love it.
After trying many products I found a brand of chalk spray that works perfectly. Its called “Heidi Swapp” . It covers fast so no need to build up a thick layer, and the final finish is nothing less than perfect ! Other brand chalk sprays leave small chalk clumps on the surface. Not this brand. I buy whatever color spray is on sale, usually around $9.00 a can and one can goes a long way. I have a David SLS 3 pro and other structured light scanners and I have not found any difference in my scans using different colors. On the chalk spray, it does wash off with soap and water but its dye can stain untreated white plastic. I just got a can of Magnaflux developer spray but have yet to try it. 😁
Thanks for sharing your experience! I've never tried chalk spray before. I tried Magnaflux developer once, but it went on too thick and the texture was quite rough - maybe because it was an old can.
@@sentinel3dscanning If the Magnaflux spray is going to go on thick then I will stick with the Heidi Swapp brand chalk spray. I buy whatever color is on sale on Amazon or Ebay. The different colors are all bright like Magenta and Teal for example, and do not affect the scan. I would bet they have white but when not on sale prices are around $30.00 a can vs about $10.00 a can when offered on sale. I have tried many different dulling sprays over the years so I can confidently say that I highly recommend trying this chalk spray. Keep up the great videos 😁
All i see for this Heidi Swapp spray is blue and teal and its like $19 a can on Amazon
Delivered well 👏
If I don't have a gom scanner will I still be able to use the software?
A Gom 3D scanner is not required to use Gom Inspect.
i have a broken switch to yashica t5 but i had no idea how to get so tiny and complex object recreated. this is the way. i gave up :p
Keep going, cool chanel.
bro yopur content is dope. Thanks for all this information ypu are sahring with us. Learning from the best! Thanks again!
I got a tip to try out ATTBLIME AB2. It’s like Aesub blue but it’s a thinner surface coating. I ordered 2 cans for now and will test it out. But I don’t think i can do the same test showed here….
Let us know what you think once you've tried it out!
How is it, as well as the smell and sublimation time compared to AESUB ?
I had used it now couple of times and it's ok but if you coat the part too thick it will not disolve. Coat it once, wait a minute and do a second coating. The smell, compared to Aesub, is better.
@@Todestelzer I guess the smell is very light almost non-existent ? Compared to AESUB which you can coat thicker it still dissolves ?
@@christopher8116 buy booth and test it. I would recommend the orange Aesub. It stays longer on the part.
I've tried generic foot powder spray, talc powder mixed in isopropyl alcohol in a spray bottle, and just dabbing on baby powder with a foam brush. They all worked great for laser scans, tho I was more surprised how much it helped a photogrammetry scan I was working on. HUGE increase in quality. It's one of those things I've only recently learned about and wish I knew years ago, when I first started messing with 3D scanning, lol. Great video, pleased to see this info spreading around.
I use a Teflon Dry release agent from Miller Stephenson. Dries almost instantly and cleans off easily.
I had not heard of that option. Thanks for sharing it!
First off, great video! I went to your channel to see what other content you have, and i was surprised to see your first video listed was only 10 months old. Amazing content/quality for such a fresh channel. Can't wait to see all the stuff you end up making
crikey, you want a bit mad with the aesub blue. the temptation is to spray until it looks white, but actually a quick, light spray and leave it a few seconds , it goes white.
Yes, I certainly applied way too much on the first trial, and the error of my ways is made painfully obvious by the outlier data point visible at 7:14! I made sure to apply less on subsequent trials. Thank you for the tip, Andy!
I was thinking the same thing
I usually use dry shampoo spray but I was sent a couple cans of AESub (blue and orange) and really like it. Unfortunately it's very expensive.
Thanks for sharing your experience!
How many different scanners you have? Also do you have a website and cost for object scanning?
Hi, Dan! We have one 3D scanner - a Steinbichler Comet L3D 5M. It has 5 sets of lenses to accommodate a variety of part sizes. You can find our website at www.sentinel3dscanning.com. Our Pricing page includes the cost of common job types and our hourly rate. If you have a specific project in mind, send an email to info@sentinel3dscanning.com and we can discuss your needs further. Thanks for watching!
Who did you use to 3d print the part?
For this part, I used Shapeways. For a project that will be featured in an upcoming video, I had to use Protolabs because I needed higher resolution prints. No complaints about either company. It can get expensive if you need parts right away, though.
thanks for the video, I learned a lot
Thanks for sharing your knowledge of these products. It would be interesting to see how they compare to Aesub yellow, which is supposed to be their ultra fine vanishing spray.
I'll have to look into that one. Looks promising!
🙂 𝚙𝚛𝚘𝚖𝚘𝚜𝚖
Very cool! Thanks for the info!
Can you scan a ps4 loser and upper shells separate?
Yes we can!
I sent you an email through your website email let me know how we can go about business hope to get your reply asap
