- This video is part 3 of my attempt to build an affordable 3D Priner filament recycling setup. Brought to you by PCBWay. Register at jle.vi/pcbway and get a $5 welcome bonus!
In this video, I'm going to share with you some quick updates on my affordable filament recycling project... You'll see a few steps forward, a few steps back, and, you'll learn a few valuable lessons that I, unfortunately, have had to learn the hard way...
This video is going to be a little different than the others in the series... I've run up against some major setbacks, as you're about to see.
But, my hope is that it will not only be entertaining... but also, that it will help any of you who are looking to DIY recycle 3d prints, by alerting you as to which issues you need to look out for.
It was a frustrating couple of weeks, full of, quite honestly, REALLY stupid mistakes... but if this helps any of you 3D printing enthusiasts build your own DIY recycling rigs with fewer headaches, I guess that's something... right?
Anyways... sit back, relax, and prepare to learn how NOT to build a DIY filament recycling setup.

Thanks for watching guys. I know, I'm an idiot. Be gentle in the comments.
No man, you're brave. Not just for sharing your missteps, but for undertaking such a project to start with!
Idiot status is only reserved for people that don't learn from mistakes and are afraid to try new stuff😉 so dont worry mate !
something to consider when next you are discouraged and don't want to shoot b roll of a catastrophic failure: even for crafting youtube, the crafing itself is secondary to telling a story about yourself, and those embarassing frustrating, and above all vulnerable parts of your journey to craft the thing are the most interesting part of that journey. if you had just built a super good plastic thingy first try, you'd have shown us one video of a plastic thingy working and we'd have all watched it, agreed "ah yes cool thingy" and clicked away during the ad break. instead you have a story about growth and struggle and friendship and whatnot. Film the worst parts, cause they might be the best parts
oh. and we end up learning more about thingy craft from videos like this than of perfectly assembled ones
We appreciate the honesty. I'm sure we have all made similar mistakes before when learning!
Stay safe over there!
It's very respectable that you leave nothing out of your documentation in this journey, showing us both the good and the bad that you're doing, instead of hiding all the mistakes you're making, and only showing us "good" results.
It's really great showcasing all the mistakes in your journey so that others can avoid them. Awesome job!
Thanks for the kind words of encouragement. I'm just glad I can turn lemons into lemonade by sharing the journey, because otherwise, let me tell ya... it would be pretty hard to soldier on with so many screwups already!
Not the first time that someone share some mistakes, but it's definitely the first time that i see someone totally screwing up the project as i always do 🤣.
Loved this video and subscribed!
"Success is a poor teacher." A saying I've had many opportunities to appreciate :D Thanks for sharing your experiences! There is so much more to learn this way.
You need a flexible coupling such as a 3-jaw lovejoy coupling. Each side has three pegs sticking out with a rubber piece between each side. This allows for slight misalignment.
On it. Thanks.
Keep it up and stay SAFE !!
Thank you, I will
It's brave of you to be this honest and share your mistakes - so many people are too proud to do that. Thank you - this way we can learn together!
Thanks so much for these videos
I am building an injection mold machine from scratch and your videos on these series are really what i need now to learn about the importance research, design reviews, and patience.
I'm all in, in seeing how these process goes. Also give updates on the cost of the project so far.
Thanks again
the failures and hiccups and problems are exactly what I'm here for, and I cannot describe how grateful I am that you're sharing that with us so that we can all learn what to look out for. much much much more useful than just "I built a thing and it works". I can't imagine how much work you've put in to troubleshooting and building everything, and I can't thank you enough for that. I'm super eager to follow along for the rest of your recycling journey, and I hope to join you on it some day soon and begin recycling filament too!
Might be a good idea to add a microswitch to that perspex lid so the motor can’t run if the lid is open. For your safety and your kids.
This is a terrific idea. The VFD /probably/ has either an Enable or Disable input that can be used for exactly this purpose. It should /also/ have an ESTOP input that can be used to arrest motor power immediately. He should wire up and have both of them working before any more tests.
This is so REAL!! Sometimes unexpected things just happen. Anyway, Nice BUILD, Jon! 👍
Thanks! And thank you guys for always being there to help me fix my screwups!
thanks for sharing your journey, it helps to see what others struggle with so you don't give up from frustration with your own problems with the project!
Thank you, I will
Good luck! And stay safe!
I really enjoyed this video. Pretty much the trials and tribulations we all have been thru with one project or another, so showing us you are not superhuman helps relate to the rest of us.
So glad you posted this.
Thanks so much. You are amazing.
Thanks for your update.it is delightful to see your journey
Regarding Teaching Tech's Pelletizer, do not build it without using the "Dime Mod". There is one key piece that the filament rubs up against and in a few minutes, can actually wear a groove in the part, causing the filament to no longer be cut. The "dime mod" puts metal on this crucial face of the part, making it much, much more durable. I made my first piece out of PC-CF with 7 perimeters and 100% infill. A groove was worn in it in about 15 minutes of use. I used the same material and parameters with the dime modded part, and after 2 hours of pelletizing, it still works perfectly!
I really really really appreciate how open you are about all the mistakes. It's really something I can connect with. Lots of doing steps a through M and then having to go back five or six steps at a time to fix something that I messed up.
Keep up the great work!
I'm so glad!
Gotta say it's highly commendable how much positive spirit you have in this entire process, especially considering the political environment that you're having to endure on top of trying to figure this all out. I wish you luck and success in your journey to affordable filament recycling!
Love the video man! Hope you and your family stay safe!
Thanks for sharing the progress! It's always a pleasure to watch. Stay safe and happy vacation!
Very cool update!
Safe travels for you all!
LoveJoy couplings are your best friend in these situations. I use them on 500hp coupled motors. It allows for perfect alignment too, and gives some cushion in high impact situations such as grinders.
Amazing series! Love your videos! (you can always add more humor) Be safe!!!
I love the fact that you show the good and the bad.
I am really hard on myself when i screw up. I think that its because, i compare myself to what, i see makers, like you, do online.
Its the exact same thing, as social media messing with peoples selfworth.
All you see each day, when scrolling Facebook or Instagram, is other peoples amazing lives, because they only show the perfect moments (enhanced with a million edits and filters).
Every project has ups and downs, and i love the fact that you show both!
This comment makes it all worth it!
Right, because of this video I don't feel so bad about my screwups, ha.
VFD will stop motor immediately if you wire a stop switch to the control terminal and change the stop setting from coast to braking. It's usually in the first or second layer of parameters. Change the setting to variable load as well, it will help with torque curve and life of the motor
A love-joy or spider coupler will help with some shaft misalignment. It will degrade faster but you can experiment with 3d printed inserts.
3D printing aside, stay safe. Being in the States, the conflict going on in your backyard seems so far away. Regardless how a particular person feels about what is going on, innocent people on all sides are in danger. Keep your family safe, and keep going.
Thank you! Please try to stay safe! (You and your family)
Test motor movement and direction is called a bump test in the manufacturing industry and electricians in a factory always work in pairs or teams.
You just demonstrated why.
Most VFDs are defaulted to coast stop, but many also have a breaking function as well.
Stay safe !
Thanks for not only showing the successes but also the roadblocks, which in my opinion are much more valuable :)
Great project! Sharing mistakes is so very welcome! Much respect for your positivity despite what's going on in your backyard. Take care and stay safe!
Something you might try: take the inconsistant filament you got from running the 8mm shreds through the extruder, pelletize it, and run the pellets through the extruder. I'd be curious to know what the results of that are. Good luck!
Keep watching the video, lol... There is no shredder anymore ;)
You want to melt the plastics as few times as possible, otherwise the polymer chains break down. That can be reversed, but you’d need to put the plastic in a low vacuum with only a bit of argon or nitrogen as inert gas, ideally heat it to around 260°C and then keep it there for hours, so the polymerchains can „relax“ form longer chains again (that’s how I understood it in German „school-chemistry“ at least) and also don’t oxidize with oxygen in the air. PET is especially prone to oxidation, in fact so much that sometimes they use vacuum extrusion setups, so when the plastic exits the screw extruder, it doesn’t come in contact with air. Nylon for example would have to be chemically split from polymers to monomers, that can then later be made into completely new nylon basically. NileRed made a video where he synthesized nylon, I watched it long ago, but I bet it wonderfully explains the concept as well. (Just a fun fact I thought someone would be interested in)
Hi, 1) I hope, that you and your famili are safe.
2) I hope that somebody wrote it (I did not find it) Never ever use strait connection between motor/gearbox and machine. You have to use some caind of flexible coupler, which allows slight intolerance in assembly process.
Great Progress, it’s always easy to point out mistakes form far away but getting through isn’t as easy! Great job. I’m looking forward to see your progress.
I love your transparency. So refreshing to see it in the Social age! Enjoy your time in the states and safe travels!
Really great video! Thanks for sharing I learned a lot more than all the perfect outcome videos
Keep up the hardwork Jonathan. Stay safe out there.
As long as your final video shows none of the pain and all of the glory it will be alllll goood
Love this video. One of my favorites you have ever done.
Wow, thank you!
Stay save mate !
and don't worry too much about still releasing content on vacation ! you must also relax a bit after all that stress of the recent week...
Enjoy your trip
All the best ❤
And if you decide to still create content, i will absolutely be here for travel blogs, and positron V3 travel blogs 💯
i am not too sure of your exact vfd but after a bit of googling i think it supports emergency stops on its digital inputs which would cut power without the downramp. you should really look into adding e-stops at accesible locations near the shredder
Oh wow!! I thought the first oopsie was it.....but there was more to come!!! Glad you're ok....just remember we learn by our mistakes - we all make them (are they really mistakes if we didn't know about the risks??)
Anyway, glad you and the family are staying safe with all the war stuff....please stay safe and thank you for the content 😊
Very interesting stuff thanks for keeping the project going
Keep it going! I am in love with this series!
Thanks for sharing. Every project has its hiccups. I just think you should try make your extrusion part of the machine more linear (horizontal) than vertical. And stay safe my friend. We are thinking of you in these trying times.
Stay safe, love your journey
Im not interested in making a shredder, but I am interested in being really good at working through setbacks so Im learning a lot. Good video, thanks for posting it.
well, thats the difference between DIY and engineering. Kudos tho for sharing your experience and for keeping at it.
As a long time fan of "Make something today even if it sucks", I dig the slogan, but it will preclude our watching your videos once the kids learn to read.
Love the content, Have safe travels.
Stay safe and look after your family 😊
Thank you, I will
Your stick welding is bad and will not hold very well! You have to make overlapping puddles. Gotta hold the stick in the first spot for a sec, then move it away to give it about 1 second to cool before coming back almost all the way to make the next "puddle" weld. It will essentially look like overlapping round spots, each one 2 or so mm away.
Thanks for the tips, I'm constantly working on improving my skills. I hope it holds, but if not, I'll re-weld it :)
The previous statement about your welding isn't completely wrong, it isn't the best, but that's okay, your not a welder. That's the only thing he was right about though. I'm a Journey Man Red Seal Welder as well as a Technical Sales specialist for welding supplies. Looks like your using a low hydrogen 7018 style rod (it was hard to tell as I'm just going off of the slag , using my phone lol.) and if you are you need a smooth straight progression with alittle bit of weave, about 1/4 the dia of the electrode perpendicular to your path of travel. Work angle and travel angle are also super important, your holding it wrong and not supporting your body properly so i bet your unstable, especially after you commit to the weld. Your heat looks too low, that's why all the spatter and lack of penetration (unless your on the wrong polarity, which is possible). Look man, I know this is strange but if you want to learn to weld, hit me up, I promise after 1 day of exchanging emails or a phone call you will drastically improve your welding as alot of it is just minor things your doing wrong. Just the basics they would teach you when training that you haven't had to know or learn.
aahh, project pains. I know the feeling. I have a few shelves of projects with issue that I can't surmount. Good luck and Chag Sameach
For shredding plastics I have tested cheap TC sawblades 6" 40 tooth, opposing on 25mm axles running with a £20 18v drill shredding anything was not a problem, the size of shredded plastic, aluminiium extrusion was small enough & uniform enough to use. Apart from the danger of someome inserting a hand and being turned out as a bean burger (Human Bean Burger), this seems like a workable approach considering testing was on a threaded bar with washers and just 4 nuts.
As for your new seive to drill out those Iranian missiles have the correct curvature already, just make sure its not a UXB before beginning!
Looking forward to the next video.
The only bad mistakes are those you fail to learn from. ;-) Stay safe!
Wishing you safe travels. And yes, I appreciate the success and the failures.
Stay safe ! Super interesting project but I can wait for you to be safe ... (you means yours of course)
You sharing the diagnosis issue u had only helps the viewers not make it same mistakes.u should make a link that has it cut sheet and make details..a wiki page notion type doc..nice job
I'm very interested in this project. As a technical engineer I grinch sometimes seeing some of your mechanical solutions. Suggestion: for coupling the gearbox and the shredder I would use instead of a straight axel some kind of CV joint. This makes perfect alignment unnecessary.
On it. Thanks!
great to see it is not only me screwing up stuff...
You can also add flex coupler between the motor and shredder to deal with concentricity. Flange bearings with grub screws will never be centered. Look at some industrial equipment. All problems you are dealing with have solutions in the form of industrial LEGOs
On it thanks!
Stay safe out there, sir.
Thanks for documenting this. Failures are community science.
I'm really interested in the extruder portion to make filament. Buying bulk plastic pellets is far cheaper than filament and ditches the high cost of a shredder. I've kicked around various ways to build a good extruder and take up reel system for diameter but am curious to see your final solution.
Stay safe !
Great video love it. Might I just ask for future videos you edit out the bead work.
Thanks for sharing. Good luck I am rooting for you. After watching your video on what printer to buy I have ordered a Bambu X1 carbon and an assortment of filaments, Sunlu dryer, esun suction with bags, and a few tools etc. I haven't even got the printer yet and I'm already watching you build a filament maker! Very entertaining. I am a bit of an inventor/modifier myself, so I know your pain. Watch your Fingers don't get caught in the grinder - frustration and tiredness kills! I love the idea of making my own filament so this series is, like your other excellent vids is very useful to me. Designing and R&D the unit is a lot of work though. Maybe you will make some money by selling us kits when you figure it all out? I'm from the UK and we see what is going to some extent in part of the world, especially with aggressive protests in London. The fireworks display was particularly worrying. I hope you and your family stay safe and that you continue to have the freedom to make your excellent videos.
Sounds like I’m a bad influence ;)!
@@thenextlayer I think that you've got me addicted. I'll soon be missing the time when I could sleep at night and not be thinking of thingies! And builds. And enhancements.And.........
Enjoying the videos be safe and hope your state side trip is fun and relaxing . Hope you get to come home to a few surprises packages and a peaceful time to work on stuff.
So I came back to see how its going its not so practical after all huh? Sometimes we hope for it but its usually never the case Since this requires alot of hand work the right parts. But I do enjoy watching and you being transparent about it, And i do hope you get it working and you stay safe.
Bump. Im gonna build one once you figure this out. Time for a custom shredder from PCBway
That mistakes were made in no way kills this project. The point of this project and video series is to see what's possible if you know what you're doing and make the right choices the first time. That these mistakes are costing you time and money is OK if at the end of the project, you still end up with a solution that falls within your USD1500 budget and a blueprint of how to get their so that those that come after you don't have to make the same mistakes. In short, you have ventured into land where most fear to tread, mistakes are the cost of learning and the quicker you need to learn the more mistakes will be made. Go easy on yourself.
Thanks man. You're totally right. I'm well over $1,500 if you factory in all the parts PCBWay is shipping me to fix my screwups, BUT, I think I can give people a BOM that will be well under $1,500 now that I know what I'm doing and what NOT to buy, so... that's a win :)
ofcourse its good to see where things went wrong, what could be improved, i was planning to build my own recycler cause the only company here who takes scraps gives you a quarter of a new roll for giving them 4 rolls of filament scraps .. which is a straight rip off, and you cant even combine the points you get as it limits to max 1/4 of a roll discount per order...
Do it! I'll be able to give you a BOM that's $1500 or less, I think.
@@thenextlayer i am actually planning to build mine with aluminium extrusions, and stuff i get for free from a friend who build some cncs and got left over parts :D
as for grinders i am still on the lookout for cheaper alternatives to the grinding gears you have, i had the idea of using some wood shredders for home use, some of those seem to have not just the boring rollers inside but actual sort of grinding gears like you have, and i found oen close by that seems to be broken ( as in electrically broken )
I just want to give u a big hug :) good for you for doing all this work :) keep it up brother :) you got this :)
Thank you so much 😀
Thanks for sharing, for us to learn from. However, I keep thinking if it wouldnt be easer to just hand crank the schreder, with a very simple gear ratio setup? Unless you have huge amounts of scrap plastic, this will not run that often anyway. Would it at all be feasable? I have no experience with this, but it seems that man have been grinding things for hundreds of years without any precition engineering involved, just more hard work.
hard and irritating lessons im sure, there is no better way to learn then to just do, though im sure there are better ways lol but ones you learn yourself first hand are never forgotten. lol, still wishing you the best of luck and continuing to follow, may post a few videos myself of my progress, though ive been working on this for a few years now, and trying to find a way around buying that at the time expensive gear reducer, spent time trying to 3d print my own to only break the parts from the speed and torque, also began to realize that even if i did not sure how long it would of lasted. just received my artme3d extruder yesterday will be working on that over the next week or so while your away.
NICE! Glad to hear someone else is doing this, not just me. Feel free to message me on discord - misery likes company. The gear reducer shouldn't be that expensive, though - hit a junk yard.
Keep up the great work. following with keen interest here.
Prayers for you and your family bud! Also hope you enjoy your trip out this way in the States!!! if your near Anaheim and want something other than disney great wolf lodge is an amazing waterpark and hotel designed for kids! took my kids last weekend and they loved it!
I need to find a best friend like you have to help me get my Ender 3 Pro up and running again..
Perfection at the first try is boring. That 0.5 mm of play might only be that at the shaft, but it amplifies the further you go from the spinning point. When you show the rotation with the shredder connected, that bearing on the end looks to be moving way more than 0.5mm.
Great point!
You walk so we can run!! good stuff. but if I recycle, I would be buying mine lol save the headache! 🤣
That's a nice metaphor, thanks!
Instead of going direct from shred to final extrusion I wonder if maybe the process would do better with the shred going into a larger 4mm extrusion and then pelletizing that to then feed into the final extruder. Granted this means two extruders would be needed but if that were a real problem no one would ever need two 3d printers now would they? 😊
Taking care of your family is No1 mate, stay save. I can't even imagine how it must be living in Isreal right now ...
hey I saw that you got the A1 bambulab printer and u live in israel how did u got the A1 I saw on the bambulab website and there is no shipping for israel I would like to know how u got it cuz I live in israel too and I want the A1 too, thank you in advance
I have the A1 mini not the A1. All my Bambu printers were provided by Bambu lab for review.
@@thenextlayer oh my bad, but is there any option to ask them that they will make shipping to israel possible?
while errors can be entertaining they are highly informative, thanks
Glad you think so!
This kind of video is why I like your channel. We learn through failure, pretending otherwise is intellectual dishonesty and just uninteresting. So, try and get a new shaft, they're not that expensive.
I appreciate that! Seriously, your comments keep me going!
"We didn't do it because it's easy - but because we thought it would be easy!" 😅
It's an interesting project and I hope you will be succesful eventually!
Israel seems to be a place where things evolve quickly, yikes.
I literally laughed out loud at this. Thanks man
That's a good example why you don't mount something like that to plywood but instead steel to steel. Would that spacer have been steel, no issues. Wood is just way too soft.
Think about it -- would you use plastic, even PLA-CF to do that job? No? Then wood is not sufficient either.
Hmm I didn't think of that. You think the issue was the wood being soft?
My concern was that I'd NEVER be accurate enough in my welding to get it exactly level - but maybe what you're saying is that I should make a steel platform, and then shim it with ONLY steel until I get it level?
@@thenextlayer wood compresses easily under load. It will never make a good shim. Metal is far better.
However, your motor coupling probably shouldn't be a hard collar like you have. The problem is that you have to be extremely precise in alignment between both parts so the shafts are exactly in line. This is almost impossible in most cases.
However, standard industry couplings help with this. A "spider" coupling, or a flexible coupling, helps accommodate small alignment errors. Switching to one will make lots of large problems go away now, and reduces small chronic problems that wear out bearings and shafts faster than they should.
Perhaps some gears and a chain would give some tolerances.
Perfect use of giggity. I wonder if you could rope in a filament-making sponsor to finance your cheap R&D and eventually market and sell the recycled filament on a wider scale.
Use a lovejoy style coupler between the shredder and gearbox. Then you will not need to worry about misalignment issues.
I looked at McMaster Carr and it was like $300 for the spider style one. I’m checking out lovejoy and it’s super promising but I don’t know what it will cost. I’ll call them tonight maybe
For the time and cost of building this, do you think it was worth it over just buying filament?
I'll calculate it at the end, but... no.
I get as much filament as I want for free. It's more about not letting it go to landfills, and if I can make content out of it, that pays for itself. With that said, if you DON'T get filament free, it becomes economical after probably 75-100 rolls. That's not that bad if you print a lot or collect from your local community.
I was wondering if it wouldn’t be better if you would power the shredder with a impact drill
Not nearly enough power!
Stay safe.

Ok, what about wood chippers? They come in both gas and electric power. Also, who cares if the original extrusion is not consistant. If it is in a string, on a spool, all you need is a chopping mechanism, to make it into pellets, which work in the extrusion machine.
Wood chippers don't go fine enough sorry
