Open source filament pelletizer | Naomi Wu needs our help
Check out my 2nd channel, TT Racing: / @ttracingyt
I am passionate about finding ways to recycle waste prints and filament, so I needed a filament pelletizer. None of those already published quite met my requirements, so I designed my own from scratch.
This video also aims to help Naomi Wu, a maker with the utmost integrity, who has put the community first repeatedly. Her actions have drawn negative attention from her government, and she effectively cannot post on social media anymore.If you need a threaded insert heat press, support Naomi by purchasing this one from her store:
cybernightmarket.com/products...
This product was sent to me free of charge by Naomi for the purpose of testing, BEFORE I learned of her current situation. I was happy to pay for one, but she is very generous. It has been tested in accordance with my review policy and all opinions expressed are my own: teachingtechyt.github.io/revi...

It's really sad hearing about Naomi's situation. Her contributions to the 3d printing community can't be understated.
When I was reflashing my CR-10S, I was so happy to see her notes in the source code posted by Creality.
SIMP
She has never had it easy, she was demonitized a few years ago and demonized as well, I dont use enough brass inserts to warrant buying the tool but I will have a look at her website to see if there are other products that might be useful to me.
She's also toxic af
I didn't know she made so many contributions to the space.
Naomi's a bloody legend. My CR6-SE went so badly wrong it killed my PC, and it was her work in the background that pushed Creality to make it right in the end when they really didn't seem interested in helping at all. I didn't realise her heat-set insert tool used rubber bands, that's a genius way to apply even and constant pressure to do the job. When I get around to printing cases for stuff in some volume I'm definitely buying one of those to help with the process.
Yeah, she has a (phenomenally generous in terms of depth of explanation b/c development process & rationale often isn't documented even for open source work) video about the heat-set rig in which she mentions that rubber bands do exactly what's needed at a better cost with no risk of a wear-prone part being hard to find.
I like her boobies
Naomi Wu is really great maker and very kind person! She helped me a lot with my KZhead.
I like her boobies
Naomi's an absolute legend and everyone in the maker community owes her a debt of gratitude. Her current situation is heartbreaking and I miss her content and input. Definitely will be shopping on her site!! Be well Naomi❤
Why do we owe her btw?
@@MikeWazowski2072 as the video said she was a champion of open source in China which helped move the industry and the hobby forward, she's also called out companies such as Razor for trying to profit off of Covid by peddling cosmetics marketed as health devices.
@@MikeWazowski2072he mentioned a few things in the vid. But if you're really curious look into her, you'll find a ton of stuff she's done in the community.
@@MikeWazowski2072 We don't necessarily 'owe' her, but she has been an advocate for open source and was pushing Chinese companies producing 3d printers to use open source software. If you know the 3D printing market, its mostly Chinese companies.
@@MikeWazowski2072Without her, Chinese 3d printing companies like Creality likely wouldn’t be as amazing for consumers as they are now.
I'm glad to hear that she is around and well(?). It's nice to know that while she's less available to the rest of the world she is still able to continue her engineering that there is a way we can still support her.
And here is why the maker and 3d print community feels like an actual community. People coming together around shared interests and goals, looking out for each other for no other reason than to lift each other up. You and Naomi are a shining example of what is right in this world, thank you!
I believe that the ideals of the open source community are as close as we can get to an utopian society that actually works.
I appreciate that you didn't bury Naomi's situation in your video to just get views. I appreciate your integrity as well as you kindness toward fellow makers. Keep up the good work, friend.
I've been missing Naomi, but had no idea what happened. She is a force for good in the maker community. I hope she is able to find a resolution soon.
世界需要像Naomi Wu这样的人，请考虑再给她一个机会，让她在制造者社区与我们分享她的知识和天赋。 The world needs people like Naomi Wu, please consider giving her another chance to share her knowledge and gifts with us in the maker community.
Thanks for making this video, Michael. Naomi has been a fantastic force in the maker community.
I've only ever heard bits and pieces of Naomi Wu but it's ALWAYS been heavily positive, even when I see way too often here in the states "crap Chinese machines" when in reality, crap products are made everywhere, as well as amazing products. It's sad to see that there are some truths about the Chinese government and their censorship. I hope Naomi and her friends and family the best. I currently don't have any ideas or use for a heat set press, but I'll absolutely keep Naomi's in mind
I wish more 3d printing channels talked about this. Her situation is really rough. She is such a wonderful person.
Yes, great job pushing this situation to the forefront.
I was pretty skeptical of Naomi when I discovered her, I were pretty impressed she changed my mind about her and I became very interested in her projects. She is in a very tight space due to the same qualities that in the west would make people famous and her sexuality is clearly putting her in troubles in china. Hope she’s well and hope China will fix all the issues with their politics. Chinese people are amazing for the large majority, do not let their politicians affect your judgement about them. Go Naomi!!
Always will love helping Naomi. When I met her in New York maker faire she was so nice.
Cool topics, products, and projects! I really love that pelletizer design a lot! And wow,, that heat set insert machine would be incredibly useful for me and my business. I think I'll be ordering one soon! Finally... Naomi Wu... absolute legend, not just for makers, but the LGBTQ+ community. An inspiration about being yourself in the face of those that want you gone. I very much hope that she can find some way to return in some way. We miss her dearly.
ive been actively looking for a pelletizer forever thank you so much for doing this, and especially for making it open source.
Naomi is the best, she helped me a number of times when she didn't need to. I hope she keeps doing whatever is best for her and loved ones without feeling pressure to help anyone else. Bought a couple of LGBT China pins.
This is the first time that I have made a comment on KZhead. Thank you for taking the time to help others. I am impressed with your ability to convey a problem without putting others down. Thank You !
It is no surprise the design with a drill bit didn't work. Drill bits do not cut on the side. The helix is just for evacuating chips. An endmill would likely work much better. The lack of side cutting is also why drills don't work for fixing out-of-round holes in printed parts; for that, you need to use a reamer.
I wish more people understood this.
Nice seeing the whole process going into it's creation. Thanks for sharing! And much love to Miss Wu
Nice machine, sad about Naomi, good work on the palletizer, I need to look into this more as too have a crap ton short lengths building up, I would recommend using proper heat inserts though, those ones you show in the video are not actually heat inserts, they are used with injection moulding and are designed to be cast into place, which is why they are hard to insert properly and make a mess off your parts, the sample ones that come with Naomi's machine are the correct type.
Picked one up a couple of months back -- is it worth the money, no, but I appreciate everything Naomi's done over the years, and I needed a dedicated heat insert press. I was doing a big rebuild of 2 machines, and this tool made the job magnitudes easier.
Let's not be sad, let's celebrate Naomi's success with her webstore, and having so many friends that love her and support her :) I'm a huge fan myself and miss her videos, but am so happy to see she's still making and contributing her engineering skills to the community. If you see this Naomi, take care of yourself, and visit Australia one day please! :)
Your filament pelletizer design is absolutly incredible! It's really cleaver to use the drills rotation to feed in the filament, making the design much simpler without additional electronics.
Naomi and her girlfriend are in serious danger and I appreciate you for being brave about that to say it out loud on your platform. Not enough people are. She's been a welcoming voice for me for a long time as another queer woman in tech, and that is just as important as any of her other contributions. As for your design; This is brilliant. I've been thinking about doing something like this and you've given me a lot of things to consider in my own design. Thanks for sharing!
Thank you! for keeping in touch with Naomi.
Calling out Naomi. A brave legend in the maker space. Be more like Naomi!
I recently saw the Twitter update from Naomi where she mentions her newest book project, which happened to be posted on the day of this video. She has to lay low for the sake of her partner, but I hope someday with continued support she'll be back on KZhead again. I miss her so much. Thank you for letting more people know about her.
Instead of a drill bit, try an end mill (specifically 'side cutting', which most are). The flutes on drill bits are made to evacuate chips, and aren't typically sharp. However a side cutting end mill is designed specifically to cut in this manner. >edit< Should have watched all the way through first, just watched a bit further, the router bit should work in the same way :)
I first heard about Naoimi Wu's situation from Maker's Muse and it is so sad to hear what has happened to her. I will buy something just to support her! Edit: Her belt printer also has to be one of the coolest 3d printing technologies I have ever seen, part of what inspired me to pursue engineering as a major in university!
Very cool design. With mine I would definitely recommend only using it clamped down and never hand held. Also having a sharp drill bit to start is also very important but I always welcome improvements!
Excellent work, Michael! Really interesting machine! 😃 I hope Naomi all the best! Stay safe there with your family! 🖖😊 And happy holidays!
Thanks mate for sharing about Naomi. I was going to make my own inserter but after hearing this I will purchase from Naomi instead. She does great work. Also thanks heaps for your machine I will be getting the plans for that as well as I do a lot of plastic recycling and recycling my leftover filament. Cheers. Love your work. 😊
Hey Michael, thank you for being so supportive of Naomi. I am not in the market for any of these devices but I would like to help. Do you know is she has any sort of other way we can be supportive? Other products? Thank you for the awesome content and for being a real friend to Naomi.
Naomi is am amazing human being, I hope China learns that she is an asset and not a threat and they would gain popularity if they learn to trust and support its people.
Trust them to not expose their deliberate security "flaws"? China is an aggressive dictatorship - they aren't in the business of "trusting and supporting" anyone who gets in the way of their global ambitions.
So pleased to see Naomi is ok!
I already have the non-printed parts to make the AdaFruit heat set insert machine, but just haven't gotten around to printing the parts. Looking at Naomi's heat set inserter with the tensioned feed feature, I may redesign for that feature using the parts that I already have. BTW, the links on Naomi's product page for inserts again demonstrates her dedication to helping the community. The links are for CNC Kitchen's heat set inserts. She also links to a competitor's product (which looks very similar to (but not the same) the one in the AdaFruit Learning system that is my stepping-off point.
Great way to stumble on your channel. I've been wanting to look for something like this so thanks a ton! Going to check out your grinder next
Amazing video and so simple shred machine. Thank you. I also hope the best for Naomi
for adding inserts to round things, 3d print a v-block. ;-) also.. thanks for helping naomi! completely agree she has done a lot for makers. :-)
such a great invention! thanks for making this video!!
such a great job, my friend... very impressive. My grade-school art teacher wife is going to love my filament scraps now!!! :) thanks for sharing and all of your hard work!!
It's a little thing but I just wanted to say that I appreciate that you wait until the credits roll to ask for a like. A lot of people do it early before I have decided if I like a video, then when it ends it goes away so quickly I don't have time to hit the like button before a new video plays (takes me a moment, I watch videos on my tv mosty). I thought your timing was perfect here. And of course, as always I really appreciate the content and your support of Naomi.
Man, it’s out of my price range, but I *lust* for that heat set tool! It’s such a great design and works so well. (I hadn’t known about the setting-speed requirement previously, that alone is useful new information.) I use very few inserts, but I love tools, and would love to help Naomi. I was so sad to see her disappear from the public web. She was not only incredibly talented and a great role model for girls and women in tech, but was also a true industry force for good. She has integrity and a real drive to make at least her little corner of the world (Maker technology) a better place. I have so much respect for her on every level. I hope she’s doing ok, and hope*so* much that the forces that be will see fit to let her continue the work she’d been doing. Go Naomi! (BTW, this was the first time I’d heard an explanation of what actually happened; before your telling of it, I hadn’t known about the encryption/security angle.)
Her getting several folks in engineering to make replacement parts for an elderly lady's 'iron lung' respirator earned my respect.
I’ve wondered if a solar oven, like one with reflective surfaces to concentrate sunlight for heat, could be figured into recycling PLA filament somehow? Certainly a gravity feed could sent piles of scrap into some molds below, as they’re heated up. Thanks for drawing attention to Naomi’s situation. I was wondering why there were no posts recently.
Good job Michael. The pelletizer is working nicely. Let's hope the best for Naomi. Have a nice day.
With beagle busters pelletizer a 2 flute endmill would probably work. It gets you a full cutting edge VS a drill bit that only has a cutting edge on the tip. Love the video!
I am glad there is something we can do to give back to her. I had heard her situation was a mess currently, and she had been heavily censored. But i was clearly unaware of her shop. I had been interested in her press. But now that I know It will go directly to her and give her a hand. I am definitely buying one.
Thank you for the video, and for the time you spent on it. it's just cool, I don't have time to realize my thoughts about future development and immediately a video comes out on this channel about what I was thinking of doing, and it's simple. Thank you from the bottom of my heart.
I was looking for yesterday as she was not coming up even though I was subscribed. Shocked to hear what had happened to her a big loss to the community.
Such excellent topics and techniques covered in this video. Thank you Michael for all that you do and share. Naomi's situation is not right, but sadly she's not the only one. Wish there was more we could do in general to ensure creative and helpful people are not silenced on this wonderful planet.
i used to use the screw made for the inserts and a torch lighter. took a bit of work to figure out the right temp and approach but it worked fine as well and prevented plastic from going up the threads but i do like how this unit works
I wondered why Naomi had gone silent. So sorry to hear that. 😢
Thank you for bringing light to Naomi's situation.
Naomi is an incredible example of success for girls & ladies; thank you for highlighting her current unfortunate fate. And, thank you for demonstrating another way forward to enjoy 3D Printing & save the planet from plastic waste.
That explains so much why she hasn't been posting so much lately. So sad to see this happy to Naomi. She's such an amazing engineer. Always enjoy seeing her discoveries and breakdowns
I entered the world of 3D printing because of Naomi. She was a great ambassador for Chinese manufacturing and a really sweet person. We wish her the best and will go to her store to support her. Now we see up close what an authoritarian regime will do to just about anyone. Vote blue!
Very clear, thanks for the work. 👍✌🖖🥃
very happy to hear naomi is still around and doing things. as a woman in a hobby with very little women in it I have always respected her engineering prowess and confidence with her body. I think shes genuinely one of the coolest people I've ever heard of I hope she's okay and does well. Naomi is the type of woman that I have always wanted to be I respect her so much. This machine is genuinely so well designed. She kept costs down without compromising in quality this is an extremely professional machine. She was one of the most talented people in our hobby and I hope one day we see more of her again.
Awesome video and design. Naomi and you are the two channels who got me into 3d printing. I wish there was more we could do to free Naomi from the ccp.
Looking forward to future recycling developments. I've amassed quite a bit of waste over the years, mostly scrapped parts, but a fair bit of unusable filament as well. I've always hoped that there would be a way to turn it all around into something useful.
Looks like a must to have if you are serious about inserts, nice video.
I really miss seeing her. She was unique and really what KZhead is all about. #FREENAOMI
Wow, that end result is great. I had a similar issue when trying to shred filament, it cut/creased but did not cleanly separate. Heck, even through a micro-cut shredder I still had long strands instead of all shreds. I could have used this setup a while ago, gonna save the video for later.
if you use a larger diameter 3 bladed router bit you wont have that issue anymore
@@rexxx927 What type do you mean? There are different ones. Flattening? Joineter? Round over for molding?
@@RoseKindred flat about 20-25mm od and 8mm high
@@RoseKindred oh and keep the blade as close to the filament entrance as possible use the housing from the same material your recycling incase a chip lands in the reclaim add a magnet just incase or if you will use it alot
It would awesome for her to leave the country and be free to share anything she wants. Awesome design and thanks for making it free. Tired of seeing solutions that requires extra expensive motors and gear.
As for iteration and the brass inserts, there are other ways that require less tools and are less wasteful to iterate. Like square nuts, you just need to leave a slot to fit them in and then you can remove them again afterwards. An advantage of square nuts is that you don’t need anything other than a screwdriver to insert them.
Big disadvantage of using nuts is that when you tighten them, they also compress the plastic. This will cause deformation with most common filaments as it adds permanent stress into the part. There is no way around it Whereas a threaded insert can be tightened hard, without stressing the plastic at all (if the part is well designed)
Thank you so much for bringing light back to naomi wu
With the right brass inserts and insert tips for the soldering iron it is very very easy to get this in straight. Pro top stop about 1/2 a mm from the surface, then use some flat metal to push down on the insert. This make make sure it is flush, but it will also suck the heat out of the insert so it wont bleed into the nearby plasti.c
Nice! I designed one using off the shelf filament feeder systems from Amazon. i didn't take any further due to the aluminum cutter I designed wore out too quickly and I cant CNC stainless :(. Thanks for this!
In case you happen to read this, hang in there naomi! I wonder if a version of the heat press could be made with a soldering iron as well, like where you could but in your own soldering iron as well
what i usually do is just place a second insert on my soldering iron so the one i am pressing in can't catch, but my iron does have a very slim tip will admit, i love naomi's work and would love to get one of these
That absolutely sucks. I'm glad she's still alive and doing what she loves despite the setback. Sometimes ppl disappearr and you don't hear back from them ever after they get sent to a education camp. So atleast there is some grace.
Good work, Michael! I don't have anything useful to say; I just wanted to bump the algorithm!!!
Thanks!
I used to watch Naomi Wu's channel for a long time, but stopped when it more and more became unpacking the latest new product some sponsor sent her. That said, i wish her well, and i am happy that 'ViceMedia' who screwed her over some years ago, filed for bankruptcy. I'll happily buy something from her store
Thanks, came here to see what was up regarding eh Naomi Wu situation as I had heard just some rumblings of her going dark. The pelletizer looks really nice and well thought out. I don't really use pellets for anything so not a tool I can use, but love the idea. I just don't have space extra 3d printing desktop gadgets. That said, I have never used threaded inserts because I felt they would be a real pain to insert and get straight. So I would just do undersized holes or captive nuts which have their own issues. This press makes a lot of sense. The rubber bands seem really low tech, but honestly there is nothing wrong with that and more thought would likely just lead to an over-engineered mistake. keep it simple stupid.
I don't know much about Wu, but hearing all that she is going through is horrible. I liked the few things I have seen of hers, such as the electronic camouflage/screen she tested in public.
It seems like one of the main issues with recycling old filament/prints is making new filament. I wonder if we could somehow work on a feed system for an extruder that can handle ground up/minced/shredded plastic directly instead of trying to work of filament extruders, or, a system that can completely powder old filament/prints and then compress it into nice even pellets that the existing pellet feed systems can handle.
Thanks I've actually been trying to make a pelletizer for awhile and have been struggling found designs I liked but parts I orser aren't quite right I look forward to trying your pelletizer
Hey mate, just a small suggestion, when using a full screen text box, please invert the black & white for comfortable night reading 👍 Cheers.....
I am quite surprised she used heat for the insertion, when I worked a production job in the Clipsal factory many years ago. We inserted threaded inserts with an ultrasonic inserter, seem to have a much more secure insertion. And worked with all plastics including PVC
Love this. Great work, both raising awareness of Naomi's situation and the pelletizer. I will look inti buy the insert tool but I don't need the temperature controller as I already have one and it would be unnecessary weight/fuel in shipping. I feel like I should have a pelletizer as a duty of care😆. At a time when people are being complacent about the disgraceful waste most colour change methods create. Some even giggle about it. Oh well, that's just the excitement of new tech and I understand it but surely 10% waste is pretty poor in production jus profit/expense wise let alone the unwarranted impact on the environment so what is 50% or more? Any way I'll curb it and say keep up the good work fella
This video is kind of a full circle for me... my first 2 channels of introduction into the 3D Print world was *Teaching Tech* and *Naomi's Channel*
As much as id want to help Naomi, that tool is completely overkill compared to ones we can build as hobbyists... I made Stealthpress with parts in my drawer and it performs the same if not better particularly as i want to control the insert force. Awesome pelletiser Michael!
Thanks for the video. I am sorry to here about Noami. I was wondering why she has not posted for a while. I missed the notice from Makers Muse. I am not sure if you pelletizer will be suitable for my needs. I will have a look at Naomi’s site to see if there is some way I can help.
Does Naomi’s press tool use standard TS-100 style tips? If so, it would probably be a great match with CNC Kitchen’s heated insert TS-100 tip. Got one a few months ago and love it. Makes it as easy as possible to do heat press inserts by hand.
This look to me is T12.
+1 for supporting CNC Kitchen Tips
@@ToddRafferty it’s dope right? I had been hoping someone would make one for ages but never found one until I saw a community post of his. Ordered right after.
Naomi's story is important for so many reasons. It's also why I quit Vice long ago. Trash ethics with very real consequences.
i created a jig for my drill press that holds my soldering iron vertically. this is a nice little build, but i'll stick with my drill press as it does more than one thing. i just prefer stuff that is multi-purpose i guess.
I hope that the public interest can cause the authorities to re-think their approach. Meanwhile, I have special heads to put on my soldering iron and have to wonder therefore where that machine picks up the temperature. My soldering iron picks it up inside the head, just under the heating element, and 300 °C is great to melt solder, but a good rule of thumb is 10 °C above the melting point of your plastics. I had great results with 200 °C for PLA.
Amazing Video!!!!!
Good luck trying to calibrate your Protocycler, I have one, and cant even calibrate mine, reached out to the company and all I got was limited support. But I have repaired mine multiple times and figured out how it works, and the design has been flawed from the start. Prompted me to work on my own desktop extruder design.
And like that is sold out on her shop, well done Machel
I miss Naomi.❤
I think I was misled in this video. I was hoping there would be a solution for recycling filament here but all good! I'll check out Naomi.
It's one piece of he puzzle. Unfortunately there are a few stages. Over various videos I'm covering my solutions for each.
Only the end (tip) of a drill bit is sharp. Drills don't side-cut. An end mill (or router bit like you used) is sharp up the flutes.
Moving in the right direction... though, what we really need right now is an affordable shredder, not those overpriced, closed-source partial kits from Action Box haha 😂
Huh, I never heard of them but looked at their shredder. It is not bad, certainly a more entry-friendly one than the other plastic recycling that keeps popping up in the 3D community. Still, $900 is a tad much for just the shred box that looks to be about 6 inches. At this point, I would think that real recycling enthusiasts would have a way to affordably offer machines. An Industry plastic shredder is cheaper, size-wise.
@@RoseKindred you've hit the nail on the head. Sure, it's great that they're willing to share their progress, but they don't offer any documentation (CAD/SVG I can understand they're trying to protect their RnD/IP), but the pricing starts to be a bit ridiculous when you realize that they're trying to nickel and dime you by selling the plates, the teeth, the motion systems, the controllers separately when it seems that their future iterations are seemingly never backwards compatible. Let alone the components they use are readily available at much cheaper price points (if you know the brand, model, and measurements which they try their hardest to omit from their videos and documentation...) for example, I can purchase an equivalent worm gear reduction box for $100-250, yet they're charging around $1000 for two...? 🤔
I'd happily buy a CNC kit from them if it was both more reasonable in price as well as if they also included self-sourcing documentation of what motors, gearboxes, and electronics are compatible with their particular design. Again, it's great that they're sharing their progress, but it's also not like they're doing anything revolutionary per se. For example, xyzDIYchen has been developing, producing, and selling a worm gear based shredder FULL kit for the last 2 years or so, more affordably too. Let alone the fact that shredders are not really a new technology to begin with. idk, to me, the "revolutionary" and "state of the art" framing, nickel and diming, and lack of backwards compatibility as demonstrated by the Action Box team just comes-off as a disrespect slap to the face for the customer ie belittling our own intelligence and resource procurement capabilities, but maybe I also watch too much Louis Rossmann 😂
@@x_jaydn you can get a 1.1kW tarp motor include the worm reduction and motor for $150 :)
I love her product- heat set inserts are great and I love to use them, and precision can be a task. But as a 16 year old with no job I just cant afford that kind of one use unneccessary high price product yet. I would rather buy a second printer like an sv06 with that money. Very expensive for what it effectively is- extrusion, some metal parts, screws/bolts, and a soldering iron.
