50$ DIY 3D print Filament Extruder to Mini Shredder ; Filament Makers 2 in 1 machine Part2

This is the lowest cost and most basic filament extruder,
The cost of the parts (Extruder body) shown at the beginning of the video is about $50,
They come from mass-produced products, so they are much cheaper than making one individually.
I used a stainless steel water pipe with a diameter of 25MM and a wood drill with a diameter of 20MM
But it still takes a lot of time and tools to deal with and modify them.
The parts shown at the beginning of the video are all necessary.
This is the result I got after many attempts.
Missing or changing the structure will cause problems.
This extruder cannot accurately control the diameter of the filament, it will jump between 1.75+-0.1MM, but it can still be used for 3D printing.
Especially when printing large parts, it is difficult to find a significant difference between it and the purchased filament.
But the cost of printing will be greatly reduced, and the plastic pellets only cost about US$2 per kilogram.
If you often need to print large parts or models that do not require high accuracy, it is very worthwhile to make it.
If you buy 50 kilograms of filament + shipping costs $1,000, then it only costs $100 to make the filament at home, which can save more than $800 of the cost.
I have used it to make 25 kilograms of filament for the production of large decorations.
I have found a simple and low-cost way to improve the accuracy of filament diameter, if you want to know, please subscribe to my channel

[@glabifrons]

@@duellyiamgemini3857 I've not seen a pick-your own scrapyard (other than automotive ones) in the US since the mid-'70s (and I've looked). They seem to be a myth of TV shows anymore. As to a dump, that's where garbage goes. They don't let the public in there as it's hazardous, not to mention the unbelievable stench. That said, it'd be hard to believe you could get such specialized equipment from any scrapyard. It's not like that chopper/shredder is from a paper-shredder, that's just not consumer-grade equipment. If there is one there, it's likely shot as that's not something that someone is just going to toss out. Good luck even finding one on aliexpress. The best you could hope for is military surplus, and that's still going to cost far more than the quoted $50. Plus, he's not pointing to Home Depot, he's pointing to _his_own_website_ where he sells the stuff for literally more than 10 times what he claims it would cost. His _cheapest_ chopper option (without motor or gearbox) is nearly 4x the total build cost he quotes! All of his gearbox options are well over $50, by themselves. Add to that the sales-pitch in the description section and the whole thing is _extremely_ misleading (being very kind here). ALL of the equipment in the video is brand new, even the dual-drive extruder shown at the end (that type tends to chew itself up pretty quickly). This, in itself, proves that the video's title and description is misleading. He didn't build it for $50, not even at wholesale prices. Not even close. There have been many people who have tried this and very few demonstrations of anything usable, and all of the ones I've seen have cost _many_ hundreds of dollars, and that's just the for the extruder assembly (not the shredder). On top of all that, the entire basis of the video as depicted in the title and thumbnail (and his sales-pitch in the description) is recovery of used plastic, yet he uses brand new pellets to demonstrate extruding filament. If this assembly actually worked, he'd be feeding the plastic he shredded into it. Especially considering that pellets cost >10 times what he claims (unless you're buying in industrial quantities). I don't know why you mentioned Home Depot. If you even could find all of this stuff at Home Depot (which you can't), it'd cost you _way_more_ than $550.

Did you drill a hole in the bottom metal part of the diatom spray gun for the pipe to go out the back? They do not look like they come with holes on both sides.

[@reynaldminguez6869]

Just an idea in the cooling process since we're trying to achieve atleast .02 error in the diameter of the final product why not run it while its considerably hot into a bowden tubing then while it runs thru the tubing run it on running water to cool it off to its size, since the tubing itself is slippery enough to to slide the filament, heat resistant since it work perfectly even its use is to run thru filaments close to heat, it cost less since these tubes are already marketed. Take note that bowden tubes despite flexible are quite tough and for over heating or melting issues its safe to say to extend the end nozzle enough to reach working temperature a few degrees lower.

[@mlw19mlw91]

That could work well on lower melt point filaments like PLA, good idea :)

[@neptarclepuffin]

Need to run some calcs on plastic shrinkage and see what the actual diameter of the Bowden tubing is

How to maintain constant temperature of water the change in temparature of that water might effect the filament ?

[@ameliabuns4058]

All this needs now is a microcontroller to automate a lot of the process! I bet the accuracy would get much lower with that. 0.2mm is a lot tbh! It'd clog a lot of hotends

[@jakegarrett8109]

Yeah that will, it will almost even smash up on the extruder size too. Now I know how they made those dozen rolls I bought that are completely unusable varying from 1.45 to 2.05 (+-.25), and it absolutely will clog every time it gets to the wide part, and the thin part many extruders won't grip anymore (and I run double springs on my extruders, it physically won't allow that much travel unless you swap the idler pulley to a flat bearing). PID tuned I can see this work out well enough, although it looks like it has too many variables, the input should be fixed screw speed and just regulate the output stepper (which is easy to calculate since now you have a known diameter off x current speed you can easily compute your new ideal speed and am Arduino will have no problem adjusting that dozens of times per second with some under-shoot on purpose in your equation, although a proper PID equation isn't that crazy either).

[@jakegarrett8109]

Also the layers are horrible, no layer adhesion at the thin sections and horrific globbing for thin parts when it gets to thick filament so its very weak and poor dimensional accuracy even when it doesn't jam.

[@LiveType]

I had a project that did something like this. It's not nearly as easy to setup as he makes it seem (as most of these types of things are). Sure it looks impressive, but it's completely unusable. You really want a light based measuring control loop. A mechanical one doesn't cut it. The amount of effort that goes into making a filament with a +/- 0.05mm is stupidly hard using consumer grade stuff. I've seen the industrial machines. They're shockingly cheap for what they are, but outside the reach of almost any hobbyist. Also no guided winding? Weak sauce. If you did this "properly", the cost will be well north of $500. Mine was just shy of $1000 and that was with significant cost savings taken into account.

[@en2oh]

this is a GREAT project. Question about cooling water. Is this a problem with hygroscopic polymers? Would a cold air jet be as effective?

[@techdiyer5290]

They use it in industrial uses because water cools faster and allows the plastic to retain the size in tighter tolerances, but they dry it after wards anyway

[@en2oh]

Part of ensuring accurate filament diameter will be to apply tension to the soft filament. If it's cooled too much, the filament might be too hard to draw. I wonder what would happen if the fresh filament was 'drawn' through a 1.75mm draw plate? @@techdiyer5290

[@TheAprilChicken]

uneven filament size gives uneven extrusion on final prints. some layers will be thinner and some thicker leading to very visible layers and general poor visual quality as well as strength issues if some parts of the print are underextruded. if the filament is 1.65mm but consistent diameter than there is no issue because you can set the diameter in slicer settings.
