In this video I show our FDM resin printing journey. Thanks to your suggestions I was able to determine the mission for this video. I focused on the light source, the nozzle and on the resin itself which I eventually turned into a gel. Like the true Proper Printing style, this didn't go without struggles and I almost gave up!

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!
No worries, take your time when it's needed, otherwise you'll get the RUclips burnout. :) Creations like this simply take time as well and it's so refreshing to see.
Awesome video, thought I've tried some crazy things but this idea is cool as hell lol I prefer good videos over many videos so yeah no problem.
For fume silica you should a precision scale to have a repeatable result. 5%-10% by weight=putty. So you can to a mix of A-380 for thixotropy and glass bubble for bridging. But to achieve good result just use a scale.
DUDE, I can't wait to see you succeed on this! You're single handedly creating a whole new way of printing! Something companies hire teams of people to do. Keep at it, never give up! Every day you're getting closer, i'm rooting for you man
This is real research!
I love the ambient build montages. You could definitely make separate "companion piece" videos with just music and footage :)
Like Alan Fisher's (armchair urbanist) train and transit mixes
Can't wait to see where you take this! Been aching for a RepRap continuous fiber system for YEARS. Cheers 🍻
Why has no one commented on this lol
@@jobonotoe They're afraid of my mega mondo bucks donation
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!
That's a very interesting idea!
That is a genuinely great idea
Yeah that would also be a good alternative.
But when, as you said, you jet it between the support and the part, you already got your part at this point, so why still need the support?
@@CAPTAINCAPSLOCK111 Not after the fact, but as you print layer by layer. The glue layer is the only thing that touches the part. This way you don't need a gap between support and part, resulting in perfect bottom surfaces.
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
Usually the downside with z-hop on FDM is stringing though, which would mean leakage here. Unless the peristaltic pump can "retract" fast enough.
What about if you turned the lasers off at layer changes
@@xomm i think that the resin Is thick enough to not leak during Z hop
@@eugeniolabruna4140there's a delay effect from when you stop pumping though.
@@xomm that can be resolved with diagonal z-hop
You continue to amaze me with your ability to attack a problem and work through it. Another great video and smooth edits.
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.
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
Regarding adding the continuous fiber, I was wondering if there would necessarily be a minimum viscosity for the gel, in order to keep it stabilized when printing features that cause a sudden change in tool head direction. Specifically because there's some delay on curing due to the way the laser is masked around the nozzle. The effect might be like the situation you can force with FDM printing an inner wall of a sphere too fast it overcomes the cooling and the nozzle begins to pull the extrusion taught.
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.
That's awesome! Keep on experimenting and I truly believe that this enables so many new possibilities! I hope that you'll succeed!
This is genius! Great content Jon 👏👏
Thank you!
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 RUclips 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!
Thanks Gerolf for this comment and we are definitely in the same boat. The projects I referred to in the end of this video are indeed "safer", yet still interesting. Sometimes you need to do a project which is mostly fun to do and where you know you can handle it. Just like playing with Lego's. I think that a good mix between this helps to keep your sanity and joy into making. That feeling of burnt out is definitely what I experienced lately and I'm so grateful to how this video is received!
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 😉
Het Nederlandse gescheld maakt dit echt geweldig, succes met je resin printing avontuur!
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! 🙏🥰
Thanks, your comment helps so much! I completely lost my motivation during the making of this video and I'm so happy that I continued. Comments like these is what I keep in the back of my mind on moments like these.
We missed you
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!
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.
Nice idea. Loctite pistol dispenser for UV resin works exactly like this (minus the IV part). It's like a pressure cooker with a tube exiting from the top
Yeah was going to say gravity feeding it will drastically reduce the work of the pump so it's not trying to pull the thick fluid up and into it.
As for the rest of the problems well I'm not sure there is much you ca do about it bridging gaps, there is a reason why current resin printers work from the top of the piece down, it's much easier to use a laser to activate it at the point instantly hardening it rather than ejecting a fluid then trying to get it to harden.. It'll always drip or turns into a string causing lumps in the working surface as is the nature of fluids
Needs to heat the resin
"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!!
Gaaf, bedankt man! Succes met je studie!
This is exactly why I love RUclips. Whacky awesome projects like this
The part with the peristaltic pump is really calming and I like it.
Amazing, so glad you didn't give up. Can't wait to see the next iteration.
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.
Look at the clay extruder printers, they just use an air piston to press a pusher plate in a tube to get the flow needed. It requires a separate compressor but not a terrible option. That setup is used for dispensing paste for solder.
Amazing work Jon... always remember, the breakthrough always comes RIGHT after you're ready to give up... sometimes.
You are The 3D printing evil genius and we are not worthy. Thank you for living my other life for me and keep up the awesome work. Thanks man 👍
awesome!!! don't give up, look how far you've made it already!!!
Never give up! Thanks for your supportive comment!
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
Thanks for your advice! Maybe a combination of both the regular nozzle tip and the two o-rings could be an interesting option. The way that this seals off works like a charm!
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!
Don't give up, man!
You're one of the few youtubers that makes good quality videos and awesome projects.
None of the boring and cloned videos about upgrading an old ender 3, or 50 different reviews about another chinese budget printer!
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!
I was going to suggest the same thing, I think that May work
That'd be worth trying, thanks!
It may need quite a bit of fine tuning the ratios could be as fine as a few granules more or less to get consistency correct
So awesome to see your process for engineering this crazy idea :)
Very nice stuff! :D Looking forward to more content! :)
Thank you!
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.
Great suggestion, thanks! I'm wondering if I need to cool it down at the nozzle to make it work. Would be funny though since this would be the exact opposite of regular FDM printing.
@@properprinting oh and i forgot the mention that curing resin is exothermic and a lot of heat is created. so if you ever run into the problem that your just applied resin is flowing of the sides its probably that the cured resin is too hot and needs to cool down for a moment. gl with your project
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.
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!
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 ! 👍
Don't give up! You are one person sure, but you've got an army of people here behind you who believes in you. You've got this. Research is slow but when you have your Eureka moment you'll go down in history as the guy who revolutionized FDM when nobody else thought there was anything that could be changed. YOU'VE GOT THIS!
The real star of the show isn’t the nozzle, it’s you for not giving up
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.
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.
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.
This is my absolute favorite 3d printing channel.
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.
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.
Don’t give up, mad geniuses like you make the world a better place!!
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!
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.
The pump assembly segment was the most satisfied I've been in months.
Thank 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!
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..
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.
Just as a note, and because I really want you to see my comment, they do make syringes in huge sizes like 100ml or more. You could also make a syringe pump which can pump any number of syringes at a time, like two for if you wanted to mix materials in your new fancy nozzle. Plus it would be a convenient way to store ready to use resins. No chance of spilling and way less mess on the hoses since you could just use Luer lock. Best of luck!
Thanks for your advise! I made a video a while back where I used a syringe to print pastes and it worked very well. I used a flexible axis and the required torque was too high, so I ended up printing mayonnaise. I switched to this pump instead of a syringe because I like that this doesn't have a limited volume. Especially when printing big. I think that it's ideal that you can just refill it during print. I still favor the use of the pump instead of a syringe because I think that this enables more possibilities. Therefore, the trouble I run into are worth solving, so I can improve on this concept.
@@properprinting Awesome totally makes sense. Thanks for the detailed reply! Really love all your projects.
A ”winner” is a ”loser” that just tried one more time… I admire you persistence and think you are on to something. Keep at it! 👍🏻💪🏼
Failed experiments are successful inspirations. you my man, even if you don't reach your goal (you definitely will), you have inspired many. your pioneership has been established
Hell yea! I checked the channel for new content just yesterday!
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!
man you are pushing the endgame, i am busy with other things than 3d printing but when i check a video of yours once in a while i am like... this dude is reinventing the industry, thanks a lot for your work and research!
You bring the future of 3d printing to an entire different playing field thats way higher and way more advanced keep on going this is awsome
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.
You’ve made some serious technological innovations here. This whole video was amazing too.
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.
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.
Thanks Grant!
WOW! this keeps getting better! keep up the great work!
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.
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!
Non pulsating peristaltic pump montage was full on maker ASMR. Amazing project, execution and video Jón!
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!
Thanks Vincent!
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!
So good Jón, I can feel myself grinning each time you have a "eureka moment" or a successful outcome. Cheers, JAYTEE
I knew I liked you based on your design work, but then you go and show up being a classic mini owner and I am now sure you are the best!
This car is so precious to me and holds a great story. I literally held every single screw of the engine and I put it together with my father. I'm saving money to get the body work done and get it back on the road again. Most fun you can get on 4 wheels!
I can't believe you almost gave up right before success! Good job sticking it out that last bit you needed, even if it isn't perfect yet.
Thanks for not editing out all the trial and errors, it's really inspiring !!!
never Never give up! World need more people like you
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
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
did you try increasing layer height and reduce flow, and reduce the light intensity so the nozzle can go over the hardened resin bridges. i think all you need is a balance of flow rate and light intensity. gel is consistent enough to hold itself up during curing.
or you need a special resin formula that hardens slowly and gradually enough that the bridges will not be too hard by the time nozzle hits them. i just thought of fluorescent pigments that are used for resin casting. this pigment restores the light energy and gradually releases it in dark. I think if you add some into your resin mixture then the UV light will be absorbed by these pigments and then released gradually reducing the immediate hardening effect of the light to your resin. good luck.
I love your determination. That last print before the Benchy was really impressive! Keep up the good work!
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.
Removing the boogers that way is an interesting approach, thanks for mentioning! I started printing with a syringe in an old video where I printed food. I still like that design, but the limited volume is a big disadvantage for me. With the pump it's also possible to refill the vat during printing making non-stop printing of very large parts possible! (if it works xD)
This is awesome. Look forward to more FDM Resin printing videos. Thank you
Thank you very much for not giving up! What an important lesson in tenacity.
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.
13:55 always nice to see someone succeeding at his project 🙂
That resin looks insanely good, can’t wait for the next iteration
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.
Sooo friken clever. Don’t give up. Feels like you are so close!
Keep going! You are almost there. The last 10% of the way is always the hardest.
Wow. Just wow. Congratulations! What perseverance!
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 ...
Congratulations Jon. You are the Master of the Universe!
Thanks for your support on this project!
Don't give up, we need more people like you in the world
You did it! When you said you're giving up I almost started to cry:) I think you're just a couple of parameters away from success, so keep trying, it will bring totally new options once you fine tune 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.
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!
What an amazing video. Please dont give up. Watching the struggle/failure and then finally success is really inspiring.
You are so close to getting this. Keep going, you are really on to something!!
Don't give up!
I think a brighter uv light to 'cure' the resin faster. Your tip can't be at all transparent, though. Is must be able to clear the tip then cure a split second later. Maybe press a needle into your resin printed tip. That way the metal would shield the uv light
From my armchair it seems to be the collisions originate from the way it is sliced. Good luck man and never give up!
You're an ace! Good Job!
Keep discovery like that happening!
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 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!
Absolute boss of a scientist. I have no words, I had a hard time writing this comment because literally I have none!
Glad you didn't give up. Good work.
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. =]
I've had those days where every single step seems to be another road block. I'm glad you managed to work through it all and persevere.
