In this video I show how I print UV resin on a standard FDM printer. This has two main challenges: pumping the resin and curing the resin. I chose to use a peristaltic pump so the mechanics don’t come in contact with the resin, but I had to solve the pulsating problem of this type of pump. For curing the resin, I use standard low power lasers.

You don’t have the squish of SLA and you are not doing small cross section free form print so To counter balance the tiny surface tension effect. Start by printing the inside wall and apply a Z shift at each layer. That should do the trick and allow you to use low viscosity resin which would be the easiest to prevent leaks

Awesome experiments. Great note on safety for the lasers, but you missed a very important warning with this type of work. Photopolymer resins give off heat when curing. If you have some on your hands (even with gloves) it can burn you if it starts curing - if too much uv light hits the spot. Be careful, even a smudge can burn you to blistering level.

Thin the mix. Add a tiny spray head of resin, like spray painting, the laser cures the "paint". Attach a standard 3d print head to your rig. Precise controlled color depths for 3d prints. This way its lack of layering is a benefit. Easy to scale up to full color printing. You could also combine it with a 3d scanner and make an automated 3d coloring device for existing 3d prints.

The pulsation can be solved by using 2 tubes. Both tubes run on the same set of rollers but the outside housing has a phase shift for both tubes. This way the pulse of 1 tube falls in the dead period of the other. Watson Marlow (Dutch peristaltic pump manufacturer) has a few model doing this running in the lab here.

Thanks for the info! As it looks for now it seems not to be pulsating too much with this design. One tube makes it easier to work with, so I hope I can stick to it.

you need gel instead of liquid, liquids will move on you before curing and it retracts unpredictably. I would like to see some trace testing to tune every parameters, you can't use standard fdm parameters. You need to cover a wide spectrum of values because you're into unknown territory. We don't know if the fluctuation in extrusion is causing real issues. When the first layer is nice, then test to stack them and succeed to have consistent height. I would try pointing the laser on the nozzle and use high speed printing to avoid clogging. Considering each layer will cure more previously laid ones, the power of the laser needs to be tuned to barely solidify the resin with one pass, this will reduce clogging. We can check if the layers need to be thinner than the nozzle diameter and if prefers over or under extrusion. if the resulting parts are tacky, it's not an issue you can cure them after.

This was the toughest video I've made so far. I badly underestimated FDM printing with resin, but I'm happy with the result. The pump on itself already enables some interesting possibilities for the extruder series! If you've got suggestions on how to FDM print resin, than let us know in the comments!

What about turning off the laser on travel moves? If you are controlling it with the fan output, you can just wrap all G0 moves in M107 - M106. Then even if it leaks resin it will stay liquid. Also in DIW adding a filler to change the rheology is very common (eg SiO2 or TiO2). PS is the pump design uploaded somewhere? Kinda want to try it out

Interesting idea, love it! On a topic of predictable flow I would suggest trying a system with a reservoir residing above the printer(maybe on a shelf) such that it can introduce a manageable pressure in the tube. Pump may add the resin to the reservoir at a predictable pace and reservoir will act a a buffer to have enough resin to keep needed pressure. Then the two challenges still left: a) stop the flow and b) control the flow intensity. To be able to stop the flow I would add a small solenoid to close the resin output right at the print head; just before the nozzle. And to be able to control the flow I would try to have a prolonged/rectangular shaped reservoir, such that when rotated/tilted the height of the resin change and pressure change with it. Idea with tilting resin reservoir will require a motor of some kind. This whole idea is very dependent on ether ton of experiment or a mode to predict its physical behavior. Anyway, good luck with the project!

I think what we are seeing here is actually seeing. How we know an object is somewhere generally relies on light waves reflecting from its surface or the absence of that. This is no different. The laser light is reflecting from the surfaces and penatrating the nozel. Either controlling the light or shielding the actual nozzle or both is what will be needed. But I guess if it was that easy, they would be mass produced and on the market by now. So what do I know.

Whilst we can see “some light” at the end of the fibres, some materials have much lower transmission at UV wavelengths. For example Germicidal 250nm fluorescent tubes have to be made with quartz as glass filters a lot of the energy at this wavelength. I suspect end polishing of the fibres also has an impact.

@guillermomarturetfendt9037 Жыл бұрын

In this case it was because of the fucked up surface. One cannot cut fibre optic cable with a kitchen knife and expect it to transmit light perfectly. The cables must be cut with a special tool that makes sure the surfice is perpendicular and doesn't have defects. You also need to align very well the start of the fibre to the laser beam making sure it also is parallel to the beam. If the laser is coming at an angle, there will be huge reflections at the beginning. I liked his idea don't get me wrong, but it is pretty clear he didn't research how fibre optics cables work

Have you tried/considered a non translucent resin? I think ideally something dark like black. I think the issue is that the resin refracts some of the laser internally, and funnels it up the nozzle opening like an optic fibre. Perhaps a less translucent resin would prevent this. It would be a lot slower but you could also try doing dropwise extrusion (and retract to break the physical connection between the resin in nozzle and the print, possibly mitigating the optic fibre like effect)? or print a layer then cure it?

I work with lab instruments that use peri-pumps. They have a lot of advantages, such as easily adjusting flow and volume by changing the ID of the pump tubing. You can eliminate the pulsing by using the flexibility of the tubing between the pump and nozzle as a pressure receiver. If the flow from the pump is slightly higher than the nozzle size can handle, the tubing between the pump and nozzle will pressurise and expand slightly , acting like bellows to absorb the pressure pulses. Also, having more rollers reduces the volume of the tubing between rollers and therefore the volume that is pumped with each revolution. Most commercial peri-pumps use only 2 or 3 rollers.

@RocketMagnetUK Жыл бұрын

I used to use peristaltic pumps. I also recall them only having about 3 rollers and they definitely delivered continuous flow to lab instruments. I remember calibrating the flow and we used special tubing in the actual pump section with coloured tags on each end which indicated the flow range based on ID, these tags locked in place to stop tube movement and put the tube in the pump under slight tension.. helps with pulsing and stops tube feed. Main issue with a peristaltic is over time it damages the tube changing the flow or even wearing through completely. So another reason for the short section in the pump as you just replace that small length each time. Overall I think he should take a quick look at lab grade peristaltic pumps as they solved all these issues decades ago.

@@RocketMagnetUK I agree . There are many different designs. I have even seen hospital infusion pumps that used many flat plates operated by a helical cam to pinch the tubing in a continuous wave. A company like Watson Marlowe would be able to give him all the information he needs

Hi really nice project. I have worked in a lab for uv curable resins but I have no experience with 3d resis. There are basically two kinds of catalyst for this typ of stuff. Radical and Kationic catalysts. The radical ones have the advantage that they stop working when Light is emited which is super important for high res., while the Kationic once continue after the UV is gone but they are way slower. So you actually could use a really thick resin with a cationic catalyst. It would allow the resin to cure after it has left the nozzle. But you would need rather thick layers and would have low resolution, but you actually might be able to get super fast printing speeds. If you do not care about colours curcumin is actually a pretty good kationic catalyst. Greetings from Germany

Wow, what a cool video and idea! I've seen some great suggestions in the comment section about pulsing the lasers. I am not an engineer by any means, but perhaps a "simpler" first attempt would be to extrude the resin with the laser off, then run the same path (without extruding the resin) with the laser on to cure the resin. The higher viscosity resin would probably be more ideal, since it better resists flowing away from the previously deposited layer. Yes, you are running the same print moves twice which will greatly increase the "print time", but I don't know that speed is necessary concern at this stage. Just an idea (maybe others had it in the comments too). I am looking forward to your next video!

Incredible first iteration! I'm glad your persistence payed off. If your enthusiasm towards this project still outweighs your frustration and you're planning on a redesign, I have one possibly good suggestion: Higher pressure resin through a much smaller nozzle. If you get the pressure high enough you can form a small jet of liquid that will still be diposited even if the nozzle lifts off the surface. As a side benefit, this will increase the flow velocity giving less time for the resin to cure in the tip of nozzle (also the smaller opening will let in less UV). If you like the idea then I'd look into using a scroll pump for consistant high pressure flow. The elasticity of the peristaltic pump tube would be an issue at these pressures, especially when you want to turn it on and off quickly. Perhaps pneumatic tubing would be a good choice.

I think your on the right track using a standard Nozzle shape, the V angles down towards the tip so no matter which direction the nozzle goes any oozing will flow back to the tip. With normal fdm the plastic is always soft and will be wiped off when the direction changes and gets 'run over' in the part when the nozzle returns thus it doesn't accumulate but with resin it needs to get cleared asap. the standard nozzle looked the best if you can sort the leaks.....hope this is some help, Andrew. love watching you work ....it's FUN

@Arpad Toth just need to have enough pressure, people who have a well for their domestic water supply the water is pumped into a tank with an air bladder which then pushes into the house. Our old house had that and it kept a steady 60PSI. In theory a hybrid system would work to eliminate the issues of pulsing, a pressurized tank and the pump constantly pushes resin into this tank while an pressurized air pocket moves the water along. Just like how the well pump pushes water into the storage tank but the air bladder pushes it up into the home.

I watched the same KZfaq video and thought the process would be the end all in 3D printing. I have two suggestions. Lose the laser. Go with what we know already works, UV leds. Cheaper and easier to work with. you'll still need some way the shield people from the light. Second use a tank to store the resin and air pressure to pump it. You can control the pressure very precisely and electronic valve to turn the flow on and off. Good luck and I'd love to see you make this work.

Indeed, it seems like you can take some notes from that machine in Joel's video. Opaque white gel resin is what they use. Less UV reflection with opaque white. Gel because surface tension is unlikely to hold. Perhaps if a single laser is not pointed at the tip of the needle but instead - a couple mm BEHIND the line of resin as it's being printed. That would only work if printing in that single direction, though. Hmm.

I wish more 3d printing channels were like your's and Ivan Miranda's you guys push 3d printing to its limit and have fun with it. Ps: if you get this working I would love to see you revisit the car rim idea again with tough resin.

tremendous challenge, that effort was titanic, a lot of desperation, but science is like that, success and error, greetings from Mexico, I am attentive to your videos.

Loved this video. The biggest issue is the reflecting light really. Have you tried putting down a layer first with high viscosity resin, and then curing it? Or maybe a ballpoint pen mechanism could work to block the resin inside the extruder, you would risk locking up the ball though.

This is ridiculous… I love it! Also I think the pulsation at around minute 7 might be due to the difference in pressure and air’s ability to compress compared to water which results in the water pulsation when it’s on both out and inlet but not pulsating when in the inlet only

Awesome project. I've had similar ideas, I wanted to use a simple ring of UV LEDs instead of the lasers, but I guess your idea works better.

It is more or less the functionality of a Multijet (3D Systems) / Polyjet (Stratasys) Printer. Works exactly the same way. But rly good progress and achievement. GL with it.

I am not an engineer, and i respect you for all of this, i don't really know some things that you are talking about, and i laughed a bit too much in some parts( you are funny :D). Keep up the good job of doing what you like .
