We are going to make this work! I hope you enjoy this journey and if you have any suggestions, let us know!
To get the resin to better sit where it is extruded, you might try adding a low boiling point solvent and using the part cooling or heater block to boil it off just after extrusion. Hexane or IPA might be perfect. Of course, it might ruin the resin.
What size nozzle are you using? You could ask Max for suggestions
Once things are better worked out, an obvious suggestion would be to replace the attached lasers with a fiber optic light feed. LEDs might be cheaper too.
try adding grinded down cured resin as a thickening agent. should have the same density as uncured resin.
Moving the UV light out of the nozzle should improve things quite a bit - less resin stuck to the nozzle means less failures and more consistent "extrusion". Ideal setup would be ring light like arrangement where the nozzle stays dark and the curing process starts some distance from the nozzle. Might be worth experimenting with using clear resin prints as a light pipe (transparent plastic part stuck to the LEDs).
You, my guy, are on WHOOOOLE another level.... The creativity in your brain is just out of this world for both Video (editing and ideas) and Engineering. Hands down.
Thanks man, really appreciated!
Thanks for saying that my friend. 😇🌎✨
Could u please share the STL model of the extruder online???? thanks
pretty cool progress 👏😎
..love your hidden humor, always cracks me 😂
Thanks Adrian!
I kept pausing the video and going back to make sure i didn't miss any easter eggs lol
We are glad to sponsor this video! I really admire your interesting idea and the ability to work it out! Additionally, hope to see more people check out the SV06 by the link in the description of the video😁
I'm glad you sponsored it! Thanks! I also hope that they do, we we're surprised by this printer and it showed that you put thought into it.
How do you feel about 3D printed firearms?
Do you really think you could print a firearm with resin? Rather, you can print a brain. You can get your hopes up.
@@squirlboy250 dangerously stupid
@@Demonicwolf9 No, not at all. We have came a long way in tech and there is a lot of really good people out there putting in the work. I was asking for his opinion on the subject matter and nothing more.
I remember seeing a printer with same concept as this at FormNext last year by Massivit 3D. As far as I recall they use a photocurable and water-soluble "gel" with exactly the same process for hardening as shown here. They also have a second extruder with thermoset resin.
So you can print a soluble mold with this uv-fdm process and fill it with thermoset resin at the same time.
Anyway, it's an amazing start!
So instant curing or after finishing the layer?
What is the patent scenario around this concept? Patent attorneys can be painfully humorless.
@@ulrichkliegis4138 ViscoTec Pumpen- u. Dosiertechnik Gmb produces Moineau pump extruder called vipro-HEAD, around 4k euro.
@@jzagaja What does this have to do with a potential patent conflict situation?
@@ulrichkliegis4138 same principle?
This project is amazing. To prevent the resin from sticking to the nozzle, a cone around the nozzle might help or angle the UV lights in a different way. Ensuring there is no way the resin cures near the nozzle. As others already pointed out an enclosure might help as well to avoid unwanted light and keep the temperature more constant.
Best regards
I was thinking a little of that ptfe coating stuff that slice engineering sells or ptfe spray applied to the nozle using a towel.
To get more control on the flow, you should try a couple things.
1. Funnel feeding
2. Stronger pump that feeds an elaßtic reservoir like a think silicone tube
3. A pinch valve.
I used that setup to make a reaserch platform for molecular gastronomy, it works great.
That would be highly nonlinear and not a good idea at all.
Or just a standard motor driven syringe system with a 1mm bore capillary tube to the print head.
The production level goes up every video. The yarn and project board were the nice touch this time.
A complete rim with fdm resin continous fiber!?!? You are madman! A genius madman that is
Another killer video man! It's so awesome to see your ideas and goals working!! I can't wait to see where you take this!
I was having a bad day.. Until this video's notification came! Thanks for uploading these awesome "adventures" of yours!
Soooooo good to see that you're making progress. I hope to see more fine tuning and where this train rides to. I wish you all the best !
Congratulations on taking a standard FDM printer, adding some fun chemistry/materials and added hardware, and creating the beast of both worlds!
Surprisingly good results thus far. The challenges are it seems to be subject to the failure modes you can expect from both types of printing and printers combined, including the issue of the fumes you need to avoid breathing. Hopefully it can be figured out well enough to counter the cost of the problems with better results than either type alone can do.
I see your methodology and if it can be done, it won't be too long before it is done.
Sovol must love watching their printers being hacked like this!
Should you get it working well enough, perhaps they'll sell a kit based off your work.
You should use silica to thicken the resin. It's what we use in the industry if we need a resin to be more viscous. The glass bubbles are used in similar lines, but reduce strength etc.
The silica powder is also translucent so should cure even better.
Never stop experimenting, omg this is what the community needs! more creative people who are willing to push the limits of current technology while thinking outside the box!!
Nice! Looking forward to seeing the continuous fiber printing! :D
Try angling the uv lights so that the beam is at least a few mm from the nozzle. And at that point I think you could use a little less thickener to keep it from balling up, because those uv lights seem to cure pretty fast.
Simply AMAZING. Hope you get it perfect and someone sponsor your idea in the market. You deserve it👍
I love how you stay consistent and growing! Keep it up!
No one has ever done it better so... until someone comes up with good looking parts using CDM, those are high quality prints : ) Great video as usual.
Considering the difficulty of this project, I'd say that last benchy is extremely impressive! Great work! 😁
I'm really amazed to see how far you are making progress.
This custom made resin and the whole process with the pump could technically work on bigger scale, similar to industrial cement printers
Thanks! Yes I'm pumped about the possibilities this enables!
I've been hype about this video FOR MORE THAN 2 WEEKS!
More amazing than the printing is how you can also film it and tell the story. If I was working on a project like this it would definitely be stuff absolutely everywhere. I am always amazed how people make such innovative projects at the same time as making entertaining content. When I build somthing everything is a mess untill its done. (Typically half done)
I get so excited about your designs and show my friends but none of them know anything about 3D printing so it all just sounds ordinary to them... I can't even begin to explain the level of engineering involved!
I love your videos, they keep me so inspired!
Congrats, my friend! That's a fantástic beginning and contribuition for the marker comunity. Looking foward for the next vídeos about It!
This is what the 3D printing sphere needs, more weird experimental printers, just like there were in the beginning
Impressive! Thanks for sharing this adventure, I didn't think you were going to get it to work at all :D
You are super awesome! You have the right recipe! Patience, Persistence and Perseverance! I’m so proud of you!
Incredible job working out the mixture and the viscosities. "Aquarium decoration," I was thinking the same thing, made me laugh.
Although I can't think of a single practical application for this I've always wondered if it's possible and I'm happy to see there's somebody doing it for once!
Still, the only advantage I can think of is the possibility of better bridging and development of future processes but that doesn't make it any less exciting.
EXCELLENT. Seems a bit smaller nozzle, and possibly an internal check-valve that requires a bit of pressure to allow goo passage, but with no back pressure shuts off.
Hi. Once I had this idea and I tried to do it with UV Leds and a syringe for the resin. I used clear resin to continue curing after the nozzle was on another layer and used a "hat" to protect the nozzle from UV light.
See you.
Looks like a concrete printer. Love the barnacle benchy. Thanks for the time at ERRF
As a guy who had to work on Ipro8000's, and now consumer level fdm...
Try accura extreme white or watershed clear if you can get a hold of them. Their viscosity and photosensitivity may be the best solution to some of these issues you are having.
Thanks for the Stroopwaffels at ERRF too!
Thanks for your suggestion! Also, you're welcome!
Use AEROSIL 200 for thixing the resin (high viscosity when still, lower viscosity when moving). And Byk Chemie for Wetting and dispersing and anti settling additive.
That's interesting, thanks for your suggestion!
Would be interesting to see the physical strength comparison of these prints vs standard pla, and standard resin prints.
That'd be interesting for sure!
_"Vamos a la playa"_ and the usual right soundtrack ... You guys nailed another one! - YES I *enjoyed* this journey with you two: *cured* 😎
I was expecting the Whiteboard to fall off the wall as your friend closed the door! I am a little disappointed but still love the video!! 😅
This crossed our minds, but that thing was so damn heavy😆
I love how speechless you get when one of your endeavors finally works :)
I've seen this idea floating around for some nice. Nice to see a diy approach.
wow such amazing research and journey. I love your scientific trial and error approach, as well as your controlled chaos creative design thinking!
How am I supposed to learn anything from your video if you make me laugh so much? 🤣
You’re so creative! Meanwhile other youtuber‘s biggest accomplishment is printing things at 1000%
Just found your channel with this video. Thanks to the YT algorithm for bringing me a real gem! Such a cool idea for resin FDM printing, really out of the box thinking. Love it!!
This is awesome! Can't wait to see it improved! Keep working on it!
This is the start of a game changer, i will be watching your progress, keep the the good work.
I've had this idea kicking around for ages of a dual nozzle FDM and Resin printer. FDM to draw vasemode, Resin for the infill.
A mini paste extruder that cures with UV instead of heat, well done!
I'm amazed. This could be a revolutionary new 3d printer category. In fact I'm sure it will be. This is actually so cool and fascinating. I'm sure once this is well done out it could compete in the same way fdm and resin do. It'll be the same case of that this has certain advantages over the other, so in certain applications it'll be better. Truly amazing
Thanks! It's fun to experiment with this and come up with new insights of what's possible. I'm convinced that we're going to find some interesting applications!
Two minutes into the video I hit the like button. Love the storytelling, and the project is very interesting
you rediscovered the very first ever 3d printer tech from the 70's made in japan. using resin to fdm print.
I think you could get really good results here with a few adjustments
- screw pump gravity fed by a hopper
- higher viscosity resin mix
- shade the nozzle so that resin stuck to it doesn't cure
- more light intensity and slower print speed
Geweldig! Je hebt het precies aangepakt zoals ik het zou doen. Wat ik me nu bedenk is dat je de printhead lichter kan krijgen als je een even sterk signaal kan maken met 1 UV lamp en een lens om het brandpunt precies op print hoogte te krijgen. Dat idee met glasvezels vond ik ook mooi out-of-the-box maar ook wel vrij complex. Voor het gewicht van zo'n opstelling zou een enkele high power UV LED dat ook voldoende moeten zijn. Ben benieuwd naar de volgende iteratie!
This is a really interesting and intriguing series. It really makes the imagination run wild. I wonder if the peristaltic pump might work better if the resin is stored in a reservoir above the pump to allow for gravity feed instead of forcing the pump to draw the resin upwards against gravity. You could even incorporate a mixing mechanism to keep the resin from separating before it is pumped.
That's so cool! I love your innovative approach and your filming too! 👍
To solve some of the "sticking to the nozzle" problems, maybe it would help to have a little "umbrella" around the opening of the nozzle, so that the resin only cures a few millimeters after the nozzle...?
The best yt channel in the best country
The production value here is top tier. Keep it up. Certainly a fun concept
Incredible Cinematography, awesome video!
This is basically how all my prints look. Resin or FDM. Gave up on the hobby. Will wait until it's less of a hassle. But you're a fkn Wizard, bro. Nice.
"I've also had days like these" bro that shit was hilarious
these UV resin deposit machines currently exist at our facility we have several of them to pop out large forms, indeed we print in continuous mode. nice work.
This guy is on another freaking level.
Great ideas and implementation man, keep it up.
Still impressive... and has POTENTIAL for future research and technology. I have absolutely no doubt this could be a step in the direction to something better than both FDM and resin printing. (and it could lead to much stronger resin prints that can have much more strength than FDM or any plastic).
What a year this channel has had. Very impressing.
Your editing and production is on a nother level my guy! Also thanks for trying this out so I wont have to:)
Looks like the new issue is resin sticking to the nozzle, maybe some kind of non stick coating on the nozzle would help
you could control precisely the amount of resin by using system like in diesel cars "common rail" the nozzle is opened/closed electronically while pump just keeps the right amount of pressure
Daunting, yet interesting🤔
about continuous fiber printing, with thermoplastics, I did my own thinkering :
1st, except if the fiber can be streched under high enough temperature, the filament diameter will have to be the nozzle diameter, elseway, you will have too much plastic in the nozzle not being able to freely flow.
2nd using continous copper fiber coextruded with PLA or PETG could add the functionnality of working electical connections in print, though the fiber filament may need to be wrapped aroud a star-shape terminal to ensure that an electrical terminal gets direct contact to the copper fibers
3rd for the coextrusion process, I though about pultruding a pet ribbon along a stripped electrical wire in a 0.8mm nozzle, a 0.22 mm2 wire have a diameter of 0.5mm, leaving space but also not too much for the PET aroun it
I wont lie, this is a whole new level of printing, Ash and Glass Powder as thicking agents? Never would have guessed but Chemically makes sense, I hope you get this right man, this technology could be revolutionary, I would also say, Raising the nozzle a litt higher than the Laser focus would probably stop the build up
I keep a jar of glass microballoons on my desk at work for the sole reason that if you shake it, air gets trapped between them, and it behaves like a fluid for a few seconds until the air works its way out. It's fun to play with
I can imagine, this stuff is so weird! Your comment reminds me a bit of those snow globes.
Love the update and can't wait to see you achieve the end goal!
You should add a wipe channel on the bed somewhere. Like a v-slot the same angle as the nozzle then and g-code every layer or so to go wipe the nozzle. Or even just and upside down brush.
Great work! Vacuum pump the mixed resin to get the entrained air out of it.
if u use a resin bottle with one pipe directly to the nozzle dpped to the very bottom into the resin and one pipe into the bottle from the top only 2 cm in the air inside the bottle, and then pressure the second pipe with higher pressure air from your pump, the resin does not have to go through your pump. think about curing in a different pass when printing, then you can use more fluid resin.
Props on the engineering, never stop exercising those receptors lol
GRAET JOB ! You're too close to bring it to life. Could you mention your friend with his FDM resin printer, I mean, who send you this video
Very cool. Your resin reminded me of those pottery clay printers. I think they use a worm-drive pump and syringe pump. Would help with the flow. Also a shroud around the nozzle to block UV.
It looked so similar indeed! I want to use this technique to see if it can print the clay which would be awesome!
It took me like a good ten seconds for the thumbnail to sink in. When it did I let out an audible “OH! …WAIT, WHAAATT??”
"I decided to do something different" - "I'm gonna do something different" 🤣
I wish to share an idea, I had patent pending. I originally had an aquarium of liquid resin. A plate is submerged just below the surface. An inkjet deposits photo reactive hardener and colorant while a UV lamp cures the mix. Another approach could be to put down a thin layer of resin on the bottom of the aquarium then use the inkjet to add color and photo reactant. Each layer would be a full color photograph film. If the film is neutrally bouyant the resin becomes support. It's a fully liquid version of the powder bed with color and glue without the fuzzy texture. I had thought to add a different inkjet color to make a fiber or solid or flexible set of dots. Epson heads are better for pushing out the doping liquids.
proposed amendments:
1.instead of a pump, use a container with a plunger (such as a syringe) pushed by a screw - better control of the flow and dosing of the medium
2.stiff tubes - walls resistant to pressure (again better flow control)
3.pipes splitter just before the print head (easy change of printing material)
4. (optional) degassing of the material in the vacuum chamber before filling the feeders.
wow the edit and production is sooo good !!! inspiring
I hope everything is good with you and that you have some vids comming. I miss them! Best regards!
I’ve been thinking that 2 part resin mixing ‘hot ends’ could be super useful. Didn’t even think about this
another super cool thing (i think already mentioned in the video?) would be to print polymer solutions: PVB in alcohol, styrene filaments in acetone, or even chitosan would be awesome
Exactly!
This is really a good idea, and you're getting somewhere now. It just needs a bit more tinkering and fine tuning, but I think it's worth investing more time and effort, because I think it has a great potential beyond just producing the resin parts in a different way. Here's what I think you could try, for what it's worth:
- Resin viscosity and speed should be adjusted so that the nozzle never touches the previously extruded resin. I think increasing layer height just enough that the resin still hits the previous layer properly should do the trick.
- It would obviously be best if the light would be doughnut shaped, with the generous "blind spot" around the nozzle. I'd try to make two small circular masks which you could move along the beam to adjust the focus and size of the dark spot made of anything that wouldn't melt, like aluminum or copper foil and wire. And as much laser power as possible, so the resin cures near instantly.
- I don't know how high the percentage of glass beads was used, but I'm pretty sure you could use other materials, like metal powders, and be able to sinter the parts if that was also considered as an option. I think you'd need to have at least 60% of metal for that to work, though.
Anyway, keep up the good work,I can't wait to see the next episode:)
This is basically what some of the new very high end color 3d printers do (if you want an idea of what they can do, look up heroforge miniatures, they make custom figurines for tabletop gaming and have an option to print in color), but they are using modified inkjet print heads instead of an extruder designed for filament to deposit the resin, and that allows them to mix pretty much whatever colors they want from just 3 to 6 colors of resin (primary colors + possibly clear and/or black/white). Those printers still cost tens of thousands of dollars and are huge though.
Video Quality :10/10.
I would shield the nozzle from the UV light to avoid curing it while the resin mixture is touching the nozzle. It should be thick enough to not flow away if the curing starts like .1 seconds after being dispensed.
LOL "how can we do resin printing, but worse?"
I'm genuinely shocked you got it printing as well as you did
Consider a syringe pump. They are ideal for precise linear dosing. Peristaltic pumps are generally pulsatile and best for precise bulk transfers.
Thanks for your suggestion. I designed a non-pulsating pump ;) I like that nothing, except for the tube, comes in contact with the resin and it doesn't have a limited volume.
Maybe you should use hard tubing everywhere EXCEPT the peristaltic pump. By using the soft silicone tubing to feed the extruder, I would imagine there is quite a bit of expansion/hysteresis that could be messing up your flow rate as the pressure on the nozzle changes.
Try fumed silica instead of bubble glass. It's a thickening agent that also happens to lower viscosity somewhat when being put under shear stress, ie when it is stirred, pumped, or extruded. It also won't float and might improve part strength once cured
Loving every second of ur production
You should consider using a syringe pump, much higher accuracy and will let you not worry about pumping while you figure out the other problems. You can buy ground glass syringes or just use disposable ones.
Small scale MASSIVit printer. 3d print nerd had it on his channel.
Could you use heat make the resin more liquid? So then you can tie flow rate to temp for any resin.
Overhang free prints too…
An interesting subject would be to heat up the resin to print extremely high viscous yet high performance resins! This would only work if the additive is not the weakest point though.
Ben bijna verslaaft aan je video's en vooral met de humor en toch heel duidelijk waar je mee bezig bent.. hoewel ;-)) Ga vooral door.
Bedankt Stef!
Our mad 3d printing scientist ❤️
check the frame at min 08:12. i like the shadow circle around the nozzle maybe it can prevent clogging
