Hi everyone! Finally, the files of the Proper Extruder are released! I needed to do some improvements first and now I'm happy enough to share the first version. You can download them for free from my website properprinting.pro/product/proper-extruder/
@@didiz01 30D is similar to 80A so I shouldn't have any problems printing that ;) www.teknorapex.com/thermoplastic-elastomers-and-measuring-shore-hardness-chart
Do you think your struder design will work on a cr10v2 if I print it on the same cr10v2??? (sorry I'm from the 3rd world jajajajaja having an cr10 here In Colombia is an very luxury thing) tanks man you are awesome... (I follow you since the beginning trough different accounts... I had to change it every time I change my phone)....
The fact that despite all of the work you've put into this thing you're keeping it free is exactly why the 3d printing community is so great. We're all out here trying to make things better, not only for ourselves but also each other. Bless ya and keep at it.
I plan to do the same with my designs as they start rolling out. I know I need money, but I think everyone should benefit from the knowledge of others.
@@peenerpan113 I mean, if you're giving something away for free (or pay what you want) there's an implicit understanding that you won't necessarily be making any money off of it, or are at least not expecting to -- Ultimately what you're positing is only really an issue if you had intended to monetize it from the get go.
All other cool things aside, I think the most amazing part is that you managed something (and by that I mean "printing ninjaflex") that up until just a few years ago many companies - with, like, actual R&D budgets - tried and failed at. That's, I think, the most beautiful thing about the 3D printing "industry": I don't know of any comparable field where the line between "enthusiastic hobbyist" and "professional engineer" lie so close together. Definitely on my short list of things to print if and when I have access to a resin printer (should really check if there's a hackerspace near me, damn my procrastinating xD)
It's so cool that with 3D printing the hobbyist is able to create (semi-) professional parts! The biggest part of the work when developing a product is everything but the prototyping phase where I'm in right now. Optimizing the design to make manufacturing cheaper, do functional testing and real life testing, complying to standards, (get back to the drawing board and do this cycle again at each fail) sourcing cheaper parts (test again), marketing, packaging and be better/faster than your competitor. You quickly need a whole team to get things to the market ;) This of course depends on the product, especially consumer electronics requires a lot.
Take a bow, Jon. Not only for developing an extruder that can handle some of the most difficult materials, but also for giving a real world demonstration of the benefits of rapid prototyping and iterative design. As we say in America, knocked it out of the park.
Wow! Amazing work! I was inspired by your last video to develop a belt extruder of my own for this exact reason. I print in Recreus Filaflex 60A filament for work all the time and we constantly get buckling issues as you describe. It's so interesting to watch you go through the same problems as I have been these past 2 months. Your buckling solution is really elegant, I didn't think of it at all! I managed it in a different way, by putting the two drive belts in a slight V shape (about 2mm apart at the top pulley and 1.5mm apart at the bottom). This means there is more pull from the bottom and buckling doesn't happen (unless retraction is higher than 3mm). With this setup I've managed to get my home CR-10 printing at 45mm/s in 60A. Also when my stepper started skipping (like crazy!) I increased the gear ratio - it looks a little silly now but it works a treat! Keep going man! You inspire makers everywhere.
You're consistently one of my favorite 3D printing/maker channels on this whole platform! It's cool to see these experiments that push the boundaries of the hobby, and thank you extra for making the designs public which is incredible for the community
Long term I'd say a grooved bearing on the antideflection area. It will give the belt only one place to go. For grove radius use filament radius in addition to belt thickness.
Great video! The production quality is incredible, and it is nice that you show off your failures, so even we can learn from them. Great job on the extruder!
Really love seeing the design process and also the hardships you had to get through. Your extruder looks and performs like a monster =) Thank you very much for the video!
Congratulations!! It was really nice to see the iterative process, as you encountered problems and engineered solutions for each in turn. Great work, great vid!!
If I can give you some advice, I would mount the spool on a pair of bearing without a cover nor grease (naked bearings) it will really reduce the force required to unwind the spool. This only is for flexible materials ofc
Greetings, Surely you are the most over the top 3D R & D engineer in the world. Well I've only been viewing all things 3D for 3 years so there may be some others. Thank you for a great presentation and commentary. You're a true joy to watch with chips and a cold beer. All the Best in your efforts, Cheers Doug
That was very impressive work. Thank you for taking the time to create a video that shared the entire design process with us. That's both inspirational and educational, particularly for young want-to-be engineers.
Oh wow, this is awesome. I always look forward to your videos and seeing what you've done. Thanks for making this open to the community as well! Goie werk.
i've been watching your channel for 2 years and gotta say everytime is see that notification i'm excited to my core and you always deliver, keep up the good work
God I love that process you go through of trial end error and error and error 😂 It is such a fun thing to watch, and then ofc the joy is over and the fun is ruined because you fix something great, again, that the world has never seen, again, and all that. Dude you're a freaking 3D designer rock star !!
Dude! That's simply OUTSTANDING!! 🤩 I've only had moderate results with 80 on my Hemera, and ice trued countless dozens of settings and configs, as well as different hardware... Although it's printed every engineering filament I've thrown at it - sub $150. I think it's safe to say there's a Proper Printing "Prints All" extruder coming in my near future! Bravo my friend! Excellent work indeed!!
I've been printing flexibles for over 5 years now (started with M3D's "Tough 3D Ink", now working with NinjaFlex 85A). Really happy to see the innovation in this extruder. Next up, maybe switch the hotend to a short, all-metal? I got burned (business/money sense, not heat) on my last large printer and I'm currently hunting for the most suitable out-of-the-box (i.e. minimal mods) printer for flexibles without going into the crazy stratosphere of $5K plus machines. Seeing what you've done here is a *tremendous* help in that hunt! Great content!
how these videos only get around 250k views is beyond me. this is some high quality stuff. So much work shown in such an impressive way. dude this is inspiring
Awesome work man. I designed my own extrusion idler for my Ender 3 V2 and flexibles were my primary concern since hard plastics haven't even given me anything more than slight quality variation from loose or overly tight setup. The hardest part was to ensure the filament path stayed perfectly straight, the slightest bend and it would kink seconds into the test. Still need to go in and beef up parts of it, the first version lasted a few month and then began to bow without any solid support. Plan for that is to print thicker base with two snug fit holes to insert a thin steel rods, just a couple out of old CD drives. As I learned you have to treat the pressure as a source of heat deformation, same effect just takes longer.
CONGRATS BRO!!!!! no small feat, i have been following the development, i am so happy for you that the belt drive worked, am thinking adding it to my own printer, but what is the weight of the extruder assembly with metal parts and all?
I know the TPU gear was just a test piece, but TPU is actually an awesome material for quiet low backlash gears if you do herringbone with zero clearance and 100% infill. I'm using TPU planets in my E motor gearbox. I think it might not work well for low speed high torque output, but it's great for stepping up speed.
Me too! Fun fact, APS tech solutions aps-techsolutions.com/en also uses the same type of belts and I had a great chat with them. They print a lot of Nylon with carbon fiber without any problems. This gives hope!
@@properprinting My go to belt when grip is important are OptiBelt. We use Optibelt ZR series on toroid winding machines where the back part of the belt is used for friction tensioning the wire, and we tried a ton of belts. Optibelt's rubber compound seems to provide the best grip, uniform wear, ideal hardness, not to rigid and not too soft. The grip might be not important for flexible filaments, because the filament itself might grip on a harder belt, but might be important when one wants to print harder, possibly slippery filaments as well with the same setup. Belt backs can also be coated. We found a company that offers twenty or so coating materials with different hardness, grip, abrasion resistance and so on, especially for the purposes when you want to feed material with the belt, like conveyors and such. The only reason why we don't use them on the toroid machines is cost, mainly. The Optibelt ZR was "good enough" for us so far, and the coated one would't fit the machine easily anyway. Still good to know that it is an existing thing when needed.
WOW! I am SUPER impressed. Excellent work sticking it out until you had a usable design. I would like to see something printed that is appropriate for the properties of the material; not sure what that could be, but something that is not just an aesthetic gear, but something that requires 'rubberyness'. Thank you.
This is the proper channel! Always exciting engineering work delivered with the right amount of subtle humor. I'm always looking forward to the new videos. Can the extruder be printed with FDM too or does it depend on the precision of resin? I'm also wondering why you need such a big motor. Is it because if the friction caused by the large contact area of the belts?
Thanks Max! It's designed in such way that it can be printed with an FDM printer. I made special versions of the base part for FDM printing. The motor mount must be printed out of ABS, Nylon or polycarbonate because of the heat of the motor. There's quite a lot of force between the belt and filament causing friction. It's a fine balance which probably can be improved. Right now I want to make sure that it can generate enough back pressure and a bigger motor is not a problem for me (this stays cooler too)
@@properprinting One solution to the stepper motor temperature problem with a PLA or PET-G filament would be to use a stepper damper, this would isolate the temperature from the motor. You should get a stepper with a longer shaft or make the gear shaft longer to reach the motor.
Not only is the design fantastic but I love the way you put the video together. I loved everything about this design/ idea and the way you presented it. Amazing work. This video got you another subscriber. I will continue to watch your videos going forward.
I bought one of my Felix 3D printers second-hand from a research team that had been experimenting with printing flexible filaments with limited success. Really interesting to see your approach and the results were better than I would have thought.
You fully have my attention. I need a new extruded set up for my Ender 5 Pro, and this looks like it could fix all my extruded issues. 🙏🙏 Seriously you rock!
very nice iterative-design journey! Shows the problem -> solution -> somehow another problem popped up -> solution, again path very well :D The extruder looks very cool and seems to be technologically quite advanced!
Yes! Finally! Im so exited when you channel is shown as a notification in my cellphone. Very nice video. I have a little thing to say. I have learned that even the smaller steppers, and even without gear readuction, have enought power to push filament. So going with a bigger mottor maybe is a workaround that works, but it no solves the problem. I can suppose that in this situation, is a good solution, because I can guess that the extra force the motor have to do, is because the flexible filaments is rubbing agains all the path between the belts and the extruder. But anyways is a detail!... keep making videos, you are my favorite youtuber! have a good day!
Thanks! The downside of this that it requires more force, also with PLA. I experienced something similar with printing the guitar neck. So, or I have to accept it, or I have to make a larger gear reduction. My goal eventually is not to extrude plastic with it anyway, just a cool extra feature ;)
Great video and even better accomplishment! I’m new to the 3D game and glad to have stumbled on this video. Excited to see all your past and future content. Congrats.
You sir, are a genius! Normal drives depend on biting in to the filiment to feed and assure positive displacement. But TPU just deforms out of the way. Yours grips it over a long segment. The only issue I see is how long will the belts last? Rubber likes to oxidize and off-gas. I wonder if it'll rapidly degrade after coming in contact with 10kg of filament? Might still be worth it to keep replacing them though, if you have to print a bunch of TPU.
What an impressive journey since your first video! 👍 This extruder is, as usual, a beautiful piece of engineering, it even looks like a Swiss clock mechanism! I love to see this neat models on your screen ❤️ Continue to push the 3D printing further, maybe Joseph P. will hire you soon 😉
That is incredible. I always love your videos (especially when you wire the extruder backwards) I use many of your modifications on my Ender 3, and love them all. This might be one I have to try at some point.
I won a 1Kg roll of BASF Ultrafuse 316l and debinding and sintering from the TCP show and have been earmarking parts to be printed in this material and your extruder has had my attention since you first revealed it to us, when I do get it printed and processed I will send you some pics and video of it although itv may take some time as I have some more smaller parts to design and print to get this material used up as the whole 1Kg has to used up before I send it to be processed
I just received a new set of diamond lapping pastes and papers which I will use to get a beautiful polished finish to the parts, I am also looking into getting some coloured anodidsed nuts bolts and washers for it, will make a great accent colour!
I must have missed this video! Glad I saw it. Freaking wicked design man. You must read your Mcmaster catalogue all the time like I do. To know that those very unique parts exist at all. Maybe a small yet very custom spring steel sheet metal part to replace your belt pushers. It would be much more robust and wouldn't lose tension as it wore
Dang, I was on the edge of my couch with this one... WELL DONE ! ! ! ! TPU's will for sure, teach a Kat new curse words...lol ... I enjoyed this video.
Love the design of the extruder expect for the weight. It might be interesting to design something that could be used on the high speed hevorts and ratrig printers. I'll post it if I end up doing something like that

great video! to clean the resin tray of anycubic use GASOLINE!
Thanks! Good tip, I'll keep that in mind!
Right no one had created extruder before this that could print TPU perfectly
That is incredible. I always love your videos (especially when you wire the extruder backwards) I use many of your modifications on my Ender 3, and love them all. This might be one I have to try at some point.
Protect this man at all costs
This is the first time I have seen this I love it he is amazing.
I won a 1Kg roll of BASF Ultrafuse 316l and debinding and sintering from the TCP show and have been earmarking parts to be printed in this material and your extruder has had my attention since you first revealed it to us, when I do get it printed and processed I will send you some pics and video of it although itv may take some time as I have some more smaller parts to design and print to get this material used up as the whole 1Kg has to used up before I send it to be processed
That's sick! I'm also working on something with that filament (I don't own it though) I'm very curious about your pictures!
I just received a new set of diamond lapping pastes and papers which I will use to get a beautiful polished finish to the parts, I am also looking into getting some coloured anodidsed nuts bolts and washers for it, will make a great accent colour!
You’re a genius. Amazing engineering 👏🏼👏🏼👏🏼👏🏼👏🏼
I know I'm late but that look you had when changing the fep sheet was hilarious, I just changed mine this week and its soooo tedious.
Try cutting a 0.8mm radius groove into the back of the belt. More grip and better tracking.
I must have missed this video! Glad I saw it. Freaking wicked design man. You must read your Mcmaster catalogue all the time like I do. To know that those very unique parts exist at all.
Maybe a small yet very custom spring steel sheet metal part to replace your belt pushers. It would be much more robust and wouldn't lose tension as it wore
Awesome video! Educational and entertaining. I love how you own your failures. That's the best way to succeed.
This thing is BEAUTIFUL!!
I really like the ASMR build aspect as well
if you ever sell these as printed id buy one, this is a fantastic design!
Great work! This is an amazing extruder. I really think this has a lot of potential.
Dit is echte innovatie, geweldig gedaan!!! 👍👍👍
That extruder is very pretty!
Amazing work. You got some mad engineering skills
Cool to see your current work
Lovely project, would be nice to see how perfect layers are up close, as filament aren't biting in to the filament compare to metal geared extruders.
i feel so happy with you my friend! great success!
Absolutely Genius and climatic!
Thanks! I'm very happy how it fits the Mutant perfectly!
epic designing and another cool project
Since I've only recently been stepping into flexibles, this is super impressive! I'm about to move out to NinjaFlex
Keep up the awesome work!
Congratulations man!! This is awesome 👍🏻👍🏻👍🏻👍🏻
Awesome work dude! Love how you include all misshaps
Linus (from linus tech tips) always drops everything, Jon from Proper Printing always extrudes backwards xD
Dang, I was on the edge of my couch with this one... WELL DONE ! ! ! ! TPU's will for sure, teach a Kat new curse words...lol ... I enjoyed this video.
Love the design of the extruder expect for the weight. It might be interesting to design something that could be used on the high speed hevorts and ratrig printers. I'll post it if I end up doing something like that
