I love the ambient build montages. You could definitely make separate "companion piece" videos with just music and footage :)

It took way too long for me to post a new video and a lot has happened since. I’m back and we are going to make awesome stuff! You can find the printable files of the pump on my website properprinting.pro/product/non-pulsating-peristaltic-pump/ I hope you enjoy this video and leave a comment if you’ve got suggestions!

It seems that in the last benchy the nozzle was hitting the rest of the print during travel moves. Try to use Z hop or give a conical shape to the point of the brass tube. Awesome project

Can't wait to see where you take this! Been aching for a RepRap continuous fiber system for YEARS. Cheers 🍻

You inspired me to try printing liquid PVA. Imagine how much easier soluble boundary support would be. Just jet some warm liquid PVA between plastic support and the part. Can't wait to finish watching your video!

alright I do have a couple of thoughts, one, is that there is already a somewhat established process for printing thick liquids like chocolate, something like that likely would not work with a standard resin but the thickened resin you first made that demonstrated its ability to form its own little tower, it seems to me like such a system would work, secondly, I think once you incorporate a fiber the surface tension around the fiber could support itself much better, possibly being able to use a thinner mix than you currently need to achieve success Very cool to see this project. I also do a lot of tinkering and printing and ive been thinking about this type of printing for a while

This is why I love this channel. I appreciate the fact that you include your successes and failures during your design iterations. You can learn so much from seeing the whole process.

You continue to amaze me with your ability to attack a problem and work through it. Another great video and smooth edits.

Just discovered your channel whilst researching a resin project of my own. I previously attempted adapting FDM to resin using the leurloc syringes you mentioned, using the "Frostruder" idea. Had issues getting the flow rate dialed in as the viscosity of the resin presented challenges Ive been attempting to overcome. The gel you created shows lots of promise, I will attempt making some of my own and experimenting with different formulations. Greatly anticipating getting this technique to work myself. Keep up all the good work, you're onto something big.

This is genius! Great content Jon 👏👏

Hey Jon, I just watched the video and wanted to tell you that I think you did an awesome job in putting this video together! Over the years I have worked on countless projects that went on and on, beause I was trying to do something noone else had tried. Very often I had to leave these projects half-finished because weeks and months had gone by and I didn't have final results to show. I often had partial success at what I was trying to accomplish, but I eventually had get back to 'safer' projects to feed the KZfaq machine. Last but not least: Working on one seemingly endless project for months, can lead to a feeling I can only describe as feeling 'burnt out'. I commend you for sharing your struggles in this video!

We missed you

Het Nederlandse gescheld maakt dit echt geweldig, succes met je resin printing avontuur!

I feel your frustration and let me say: I'm so proud of you for not giving up! Such a small tweak for such and excellent result. I can't wait for Resin Gel FDM at home, this will be a game changer. You will have your own brand and line on day 😉

For the resin, I'd be tempted to treat it more like an IV bag. This gives you 3 main advantages: 1) Gravity will help push everything through the system. 2) If the container is sealed, you could add a pneumatic fitting to the top to pressurize it. 3) Easy to refill mid print, assuming you have an opening on the top as well.

AWESOME‼️ I am in AWE of your work, your research, your patience, your stamina etc etc. (Yeah, AND your videos!) For me, you are just like the BIG inventors/explorers/discoverers we read about in our history books. May you forever be connected to an abundance of inspiration! 🙏🥰

So glad you're back! You've been such an inspiration for myself and so many others! The ASMR assembly section of this video was super satisfying!

Amazing, so glad you didn't give up. Can't wait to see the next iteration.

This is amazing. I remember your last video on this 9 months ago. I can only think of one suggestion, that's to use the flexible tubing for the peristaltic pump, but immediately transition to rigid tubing like PEX after, and (possibly before). That way there's no elasticity in the plumbing, and the pressure will be constant. That should help with laying a consistent bead with a viscous gel.

Wahou! I'm following your channel from early days, and I have to say that i really love the way you come up with new ideas, how you present them in an entertaining way, share your doubts, attempts, success play dumb with your mate and keep moving forward... truly inspiring ! 👍

Mount a pvc pipe above the extruder and use a threaded rod to push a plunger into the pipe extruding the resin at a fixed rate under it's own hydraulic pressure. Also perhaps think about changing out the tubing or even buying a fiber sleeve for it so the tubing itself does not expand while trying to print.| Edit: Maybe also start a discord for people to give feedback on projects as you're trying to solve problems. I definitely thought about modeling this in fusion for you when I thought of it lol.

"ah nee, tiefus" ik ging helemaal stuk. Ik studeer op dit moment aan de universiteit van Eindhoven en wil toch even zeggen dat ik je werk heel erg waardeer. Mensen zoals jij maken de kloof tussen de industrie en academie kleiner!!

Great video! I love seeing you explore interesting ideas. Including the failures along the way, the frustration, the thought process to fix issues, and the various revisions is quite helpful and inspiring for viewers.

Found your channel recently and am blown away by all the awesome work you're doing. It won't be long before you have 1,000,000 subs for sure!

awesome!!! don't give up, look how far you've made it already!!!

i think you need to go back to the regular nozzle geometry. The reason it works for regular fdm printing is that the nozzle shape acts like a ramp, pushing any irregularities along its path back down to the print, minimizing snags etc. probable reason it didnt work for you last time is that the laser has a gap from the nozzle tip (the shadow produced by nozzle) which means the resin can climb up the nozzle before hardening. Try targeting the actual perimeter of the nozzle tip so it hardens before getting any chance to climb up the nozzle

Fantastic video and great work! I love joining you on this journey and seeing the way you approach the problem. I'm impressed that you self corrected and didn't dedicate too much time on the lens idea, it's a pitfall that many people encounter! If you feel like giving up, consider spending less dedicated time on the project and keeping a notebook ready for capturing spontaneous moments of inspiration. Don't burn yourself out! Can't wait to see where you take this.

This entiere Journey is so so cool. I am looking forward to every single Video you are releasing, but this is especially cool. Please keep it up mate, what you are creating is truly inspiring. All the best to you.

use a little of both the glass and Silicone? getting the advantages of each but low enough content to keep the bad properties at bay? totally guessing here!

So awesome to see your process for engineering this crazy idea :)

The part with the peristaltic pump is really calming and I like it.

I have worked at a medical pump company. They made both peristaltic and syringe pumps. Have you considered using a syringe to pump the resin? It would be easier to load and prime. You just need a gear reduced stepper motor to turn a screw to press on the syringe. In this way it would be easy to control the flow as well. The calculations for exactly how much resin you are pumping are very simple for any given syringe size, thread pitch, motor speed, and reduction. It would basically work like a threaded Z axis, but for your pump! I'm sure you get it.

Hey there! you can try heating up to resin to about 30-35°C if you want it to be a bit more like a fluid. Its a common problem for normal msla resin printers in lower tempratures and controlling the temprature of the resin could make this setup a bit more consistent. For the bridging problem you could enable Z-Hop. Just saying im just a noob in fdm and sla but had the same problems in my fdm printer with bridging and the temprature problem with my resin printer.

If the aim is really continuous fiber printing, you shouldn't care about bridging. Firstly, you won't have very much bridging to do, is defeats the purpose of continuous fiber in most cases. Secondly, bridging with a fiber holding the paste should be way easier.

Really nice video. As for creating a leak tight thread seal, I would just use PTFE tape on the threads. That will almost certainly create a leak tight seal. This may allow you to more easily try other nozzles in the future.

Amazing work so far, can see a lot of potential for the idea, particularly a nozzle capable of mulitple resins as well as continuous fibres/ traditional filament, could open up a lot of 3D printing potential. Looking forward to the next video in the series!

Out of the box thinking! I love it, keep up the hard work. It's defeating when things don't work out, but it's oh so satisfying when they go right. The possibilities are really open on this type of printer, and an easy retrofit for those that don't want a bunch of printers capable of one process.

Thanks for your perseverance. Most would have given up very early in your venture, it is extremely admirable that you didn't let frustration stop you. Keep up the good work!

Awesome! Love the blue color and how clean it looked when it finally printed. Good luck continuing this!

Wow. Just wow. Congratulations! What perseverance!

What an amazing video. Please dont give up. Watching the struggle/failure and then finally success is really inspiring.

The fact that you are still working on this and making progress against all the set backs is honestly the most impressive thing in hobby 3d printing I have seen. We believe in you!

Brilliant work, love the way you make your videos too! Please dont give up, we are called to do these things for a reason!

I am always so blown away by the ideas you come up with. This has been a cool project to watch. Keep it up man!

So many cool ideas come off your channel. Love watching these.

Man that is so awesome! Where many 3D printing channels have gone from cool tests and experiments to boring projects and sponsored printer reviews, you keep pushing innovative ideas like these. Keep it up man!

dont give up!, I just discovered this channel and I really loved the passion you have explaining what you do, also filming and editing is pure awesome!, thanks!, subscribed

Was looking forward to seeing another video from you, this did not disappoint! Awesome concept man looking forward to seeing where this goes

Great research! Never give up, take a lot of breaks though, wait for the inspiration to come! Loved the blue vase print!

Thank you very much for not giving up! What an important lesson in tenacity.

Wicked video bro! Definitely come back to this at a later date. You're so close to something really cool I think, nay, I know! 😉 Looking forward to seeing what other cool ideas you have 👌

Brilliant concept. I admire your ingenuity.

Man, i'm so happy to see that this fumed silica suggestion was usefull :D hope to see something awesome in your fdm resin printer, keep up good work!

This is really cool to watch you work out solutions to make this work.

You have to keep going! You're literally creating a new technology for the world! The fruits of your labor are untold but I'm willing to bet it'll be mainstream in 5 years or less. My recommendation is create or buy a small compressor. Create a sealed reservoir with a pressure transducer. Find a pressure that works well with your tube length. Then tweak the printer to control the compressor to maintain a specific pressure. I think that'll give you the consistent results you're looking for. Your pump will be more like a variable valve at that point.

I get so excited to see you post a new video! Fantastic work as always this is so inspiring! This may be a lot on the stepper motor but it would be so cool if you could create a stack on the motor that has your pump and extruder/fiber extruder in one where adjusting the gear ratio would get different feed rates on the resin and fibers.

WOW! this keeps getting better! keep up the great work!

with out a doubt one of the best videos i have seen on youtube i was on the edge of me seat for 20 mins thank you..

First time here. Never seen your videos before... First impressions -- absolutely amazing. Your excitement and the way your face lights up when you have ideas is so great. I almost cried when you said you were giving up, and I don't even know you 😂 20 minutes of video, and I could tell how much perseverance and determination you have. I'm sure it gets very frustrating, but don't give up! You've already come so far.

Honestly viscosity of your gel plays such a big role in what results you can get ... printing like this at some point becomes a material property study of the gel ...

You're an ace! Good Job! Keep discovery like that happening!

Looks awesome! This is research indeed, I really learned to love frustration during my career in science. That really helps doing software development now. :) Awesome result and together with the Proper Extruder, you're really creating some unique setups for people to try!

You did an amazing job, you should be super proud of yourself. I don't have any smart suggestions for you but I would love to see you pick this back up after a few months!

Dude this is absolutely amazing! So fascinating to watch!

One quick way I found that helps to understand issues or explain complex problems is taking it to the absolute extreme, like you did for the infinitely powerful pump. It always clears things up for everyone aswell.

This is awesome. Look forward to more FDM Resin printing videos. Thank you

Phenomenal work sir! It's also encouraging seeing you press through all the failures to success, I have struggled with that myself and almost every time I keep trying it works out in a success. =]

Please keep this work going, I'll be looking into stuff like this in my post-doc and find your content very insightful! Also I subscribed when I found you use labview in your projects!

The coaxial fiber/resin nozzle concept is incredible. Like you said, the geometry opens the door for multiple fluid injection ports - you might be able to add a second port for a "trim" line. This line could connect to a small syringe which could be used to create a vacuum near the end of a printed line, giving better retraction control over the resin. That might let you use a less viscous resin. It seems like there's a balance between resin pumping speed (specifically, how fast you can start and stop the flow) and print speed/performance. A lower viscosity plus that "trim" line control might help you achieve more control over the liquid. Don't give this idea up!

A big ol' syringe with a plunger that's a threaded rod driven by a stepper might be able to squeeze a thick enough gel that it could bridge stuff (like you said, put pressure on the vat). 3dprintingnerd showed a uv gel industrial 3d printer and it had a mechanical doodad that cleared boogers from the nozzle after each travel move. It was a tube concentric to the nozzle tube on the outside and it moved down a couple of times to break stuff off. That could be doable with your new design.

Creative and innovative project, and an informative & enjoyable video!! First time watching your channel, definitely not my last; Subscribed!

Amazing work! Not only does this facilitate continuous fibery enforcement, but also potentially the use of different resins for different parts of the print, allowing the specific physical properties of each individual resin to be best utilized. This may be one of the most significant home fabrication projects I've ever seen. Only other thing that you could possibly do that would be quite so cool. Would be to use a infrared laser or some such thing to partially melt a bit of filament ahead of the printhead for standard FDM 😜 You're doing amazing work, keep it up!

WOW. I've seen plenty of attempts at this but most gave up after they experienced the buildup on the nozzle. It looks like you're really close to a good solution, don't give up!

So good Jón, I can feel myself grinning each time you have a "eureka moment" or a successful outcome. Cheers, JAYTEE

That's amazing! no other word can explain this better, meanwhile i was watching appeared in my mind a PC cooling pump, those may are the correct size to be interchanged with the stepper motor instead of the normal one that power them. For the tubes connections i think you can also use those fittings used for compressed air (i understand testing but i think a cable tie doesnt clamp well over tube and brass) also rigid tubes may help with the flow as the one you have on can expand with pressure.

13:55 always nice to see someone succeeding at his project 🙂

What you've done is awesome, dont give up my friend

I had the idea of implementing this sort of system into an FDM printer. Great work on this project, and thanks for your contributions to the 3D printing community! I hope you can change FDM printing with this approach.

Glad you didn't give up. Good work.

Love the project! Can't wait to see the next version with continues fibers!

I love your determination. That last print before the Benchy was really impressive! Keep up the good work!

This is awesome! I'm thinking you could take a page out of resin printing and place the model at a non vertical angle on the bed and print supports for it. I also suspect that the problem would go away once there is a fiber, the resin will stick to it over the gaps. Also that nozzle is pure genius!

Sweet project! When I was at Formlabs as an intern, I worked on a hackathon project that was extremely similar to this. We also used luer locks as the nozzle, but used a leadscrew driven syringe as the resin pusher. We also ran into the same problem where the laser would cure the resin at the tip and block it, but ran out of time before we could come up with a solution like you have. I can share a photo gallery of the build if you're interested.

Hell yea! I checked the channel for new content just yesterday!

Vet zeg! Volg je al een paar jaar. Geweldig om te zien hoe je een idee blijft vasthouden en doorontwikkelen. Ideeën die uiteindelijk bij iedereen thuis kunnen belanden. Echt heel tof

The pump assembly segment was the most satisfied I've been in months. Thank you.

This is exactly why I love KZfaq. Whacky awesome projects like this

Sooo friken clever. Don’t give up. Feels like you are so close!

Man that montage of the peristaltic pump was the nicest montage I've seen in a while, also just love your content and excitement. I'm loving this project.

How about mixing the two? You can add both glass bubbles and fumed silica and try that. The fumed silica will thixotrope to the point that the glass bubbles will not sink / float out of the resin.

i just got here, but man your build segments are super nice.. i could watch hours of that kind of thing! very nice video production!

That is awesome on so many levels... I would love to see this become a thing.

great progress. you are close, i can feel it

You keep trying, it will be great when you get it finished. You are an inspiration to the rest of us to not give up.

This is absolutely awesome. Keep going 💪💪💪

Thanks for not editing out all the trial and errors, it's really inspiring !!!

You are a true engineer!!! Keep on doing research!! 😍 Love your channel FYI.

I think you are very different than other 3D printing guys out there. you are an inventor and innovator. I have recently discovered you and am happy. this FDM resin 3D printing especially with capablity to mix different type of resins throughout printing will be a big game changer. please continue working on this. i realy appreciate you sharing these great ideas on here. some of your ideas are patentable which can lead to you having your own revolutionary 3D printer range in the future. you are a problem solver this is the most valuable skill. I am an UK based medical device inventor with granted patents to my name so I kind of know what I can see coming :-) well done

Jon, this is astounding! Amazing work! Keep it up. I know it can get tough and you want to quit but man we are rooting for you here. This is insane.

When printing something like PLA and the nozzle hits the print it will remelt and you have no fatal collision. It is different with resin. It is solid and the nozzle will tilt when it hits. That leads to more resin in a spot where you are already colliding. That will lead to more built up and the next time you reach that spot it will break the nozzle. Z-hop won't help there since it is happening during print. I think you have to tweak whether the extrusion amount or the layer height. Especially at crossings of infill or outer shells. That’s why you could finish in vase-mode without any problems. You had no crossing vertices. Keep doing what you’re doing! You are onto something great!
