Having worked in a plastic extrusion factory, I can tell you he is not exaggerating at all. Plastic is a fickle thing when being extruded. Humid that day? It's gonna stick to the machinery. Then there are the static shocks you receive working with the raw plastic. On many occasions I was shocked so bad it made my hand turn white where it hit me. :P Long story short, this is definitely a get what you give process, and I admire the dedication to the craft. Thanks guys!!
I appreciate the openness, transparency and passion this guy displayed for the science that goes into every step of this process. Thank you. I really enjoyed watching this and learnt alot. I originally was trying to find if there was a way to recycle wasted prints at home but after seeing this, it may be out of my league.
I don't comprehend why there seems to be so much hostility towards this video. I quite enjoyed knowing that plastic filament synthesis is not a precise science yet. It tells me that there still is a lot to learn about making things, especially in the area of plastic extrusion. Thanks for sharing this.
man this blew my mind!!out of hundreds of filament tutorials i finally understand just from watching this!came here on advice from 3d printing food safety which is so informative.i really appreciate the truthfulness of both tutorials.very very enlightening.
"It's an odd thing to Google this because there is this void of information" Even 7 years later this is still true. I have been researching how to do this off and on for quite some time. No one really explains on a step by step bases what to do. "It truly is an art form" Everyone has their own methods and techniques and I am enjoying piecing it all together. From 2022, Thank you for this video.
I know exactly what you mean. I'm working in a company that produces 3d printing filament and I'm a main operator there. Sometimes 2-3 degree Celsius more or less can make the difference.
Good morning, friend, I saw that you work in a company that produces 3D filaments, I have an indistrial extruder that I am adapting to start producing here in Brazil, but I have a lot of difficulties in cooling where it always gets oval. Can you help me ? Could you give me some contact so we can talk better? Thank you very much
I love this guy! trying to build my own home extruder primarily for pla. this simple little video has to be the most informative thing i have found on the subject. very useful for me as i am trying to decide on an extruder to filament roll design!
Joshua - thanks on behalf of your customers for getting the information out there and spending the time. I haven't had a bad print yet that was related to Makergeeks filament. I have however had several small issues that were me on the human end....
@@georgetown2180 this information wasnt invented in the last 4 years. I have a 15 year old course explaining extrusion. A lot of videos about this topic are more then 5 years old.
Hi. First and foremost, thank you for providing this astonishing informative introduction. I have found that the "maker" movement entails many disciplines. You have provided some enlightening details with this podcast.
I have no experience with their filaments but I tried to buy a printer from them a while back and they could never deliver. After a month and a half of waiting I finally canceled my purchase. They did refund my money immediately so thats a plus. Ended up going with a Flashforge Creator Original purchased on Amazon. Im glad I did because its fantastic.
I’ve been in the blown film industry for over 25 years. I’ve also run mono filament machines way back in my youth. Plastic will never EVER go away. If this world completely bans plastic we will be living in caves hoping for a lighting strike to create fire.
Great to see you making the product locally. There are Technical colleges that not only give you data, but are good at trouble shooting. One thing you may run into is screw design and speed. When adding ferrous material, the friction will tear the bond. Also a vacuum in your primary water tank will control ovality and concitricity issues.
This guy could make some serious money if he started marketing, assembling, and servicing these machines here in the states. He's got the knowledge no one else has.
+ElGatoLoco698 Well, not many people do anyhow. Ever use a weedwacker? Weedwacker string is really nylon filament and it wouldn't surprise me if it was made in the same factories and even with the same machines but different settings.
Yeah, its like injection moulding operator needs to know the machine, but extrusion is about knowing the material on the fly. Its like another art form when it comes down to doing it.
This is why I chuckle so much at all those desktop diy filament extruders that you see 1 or 2 videos on and then they vanish. None of them realize how important the cooling is after you extrude, it or have any clue how to properly pull it out.
lot's of people on here are just talking, he on the other hand has invested in it and is making it... so shut up about how you'd buy it from china, and at least respect the man for what he did... I thoroughly enjoyed this piece... well done maker... and I would pay him to be a consultant if I ever get around to building me a little filament factory... Think of all the experimentation you could make if you had a set-up like this...
"It's odd when you google this- because it's just this void of information!" I´m working developing in a composite filament for medical implants, it is hard that you don´t find any information about but you feel great with any advance in the project
I enjoyed the vid. Even the digression into how it was a challenge to put together. If there was a bit of product marketing in it, im cool with it. Ive had to source locally after finding a couple china suppliers had a bit of impurities in thier spools. True white wasnt true white. Locally costs 5 times the price but 5 times less hassle and 10 times better quality. I can appreciate the effort put in to making high quality filament. Its noticeable. All the best.
Sounds more like americans not wanting to do international trade. Don't then complain when your prices skyrocket or somethings are just not available as americans can't do them or will not purchase overseas. Or better yet, don't wonder when international customers disappear - why buy from americans, when they don't buy from others.
Awesome video! Can't wait to read your detailed step by step "how to" blog post you of course are gonna write about this... to fill the information void on this subject i mean.
Now that's where I would buy my filament from.Very well presented on how it all works.I'm building a 3D printer at the moment and would love to get more info' on shipping to Australia maybe first some samples.
Just getting a small Filastruder to reuse my failed prints and 3mm filament went from 3mm to 1.75mm less breaks and less problems with hotend breakdown/cooking filament...
after watching a youtubers videos of his homemade filament maker I can see he had to watch this video because he made a scaled down version of this thing... only difference was he had one water bath instead of two.. so im guessing he just used slightly below room temp water and not warm, or cold. His channel is "diy chen". Probably the best diy filament maker setup ive seen.. ive seen other more simplified ones but theyre more small scale. diy chen's uses a hopper and pellets whereas everyone elses uses a shredded bottle pushed right into a hot end heated block.
Wow. I could see how fun that must've been for you to put together. You really do a good job at explaining concisely how specific the different layers of the process have to be. I was actually doing a search to see if there was a small scale version of making your own filament but thanks to your great explaining I can see it is way too many components,.time, trial and error, and financial investment, to do in a home type of setup. I'd like to purchase filament from you though. Now that I've seen how passionate and attentive to quality you are, I don't think I want t9 order Chinese spools. Hahaha
I find the water fascinating. The feedstock as to be thoroughly dried for the process to work correctly. We end-users often wind up storing the finished product in dry boxes so our process works correctly. But during manufacture the filament runs through 20 feet of water troughs. I find that reasonably hilarious.
Hi guys, we have developed a bioplastic mix from cassava which rots in 1 week under normal composting conditions. Now we are thinking of prototyping by producing pellets and eventually 3D Filaments to test it out. Any ideas on how we could go about this in Ghana? You feedback will be much appreciated. Cheers Venan

Really control the thickness of the plastic on Your enterprise is not fully automated: using laser meter line operator must constantly monitor its thickness and if it starts to deviate from the specified size - it interferes with the process? If so, as a result of such proceedings, the thickness and shape of the filament can be absolutely stable along the entire length of the coil and not to depend on the "human factor"?
A question for on the topic of mixed filament parts. How do metallic parts such as wire work in the filament manufacturing-extrusion process? I am not a material scientist or chemical engineer, but I can imagine that either metallic parts fuzing in the batch mixers to the resins. I could also see bonding the resin on a wire that is extruded in the resin-extrusion process. Do either of these approaches have merit?
Why is water used for cooling? Is air-cooling not fast enough at those production speeds or are there other reasons for this? Because normally it seems like a bad idea to hydrate filament...
