Recycling Failed 3D Prints with a DIY Filament Extruder: Artme3D

Everyone complained that I always use multi-thousand dollar equipment for my recycling project, yet I finally found a very promising Germany DIY filament extruder! Let's build and try out the DIY Artme3D filament extruder kit and recycle some old 3D prints with it!

*QUESTION* Is recycling failed 3D prints a waste of time and money?

[geekdomo]

I run a makerspace at a local university. I have been trying to work out a grant for the other recycler you showed. This one here is within our budget! Thanks Stefan!

I worked in an industrial extrusion plant, this is just a way scaled down version of our recycling process. Set aside scrap, throw into the granulators, put into bags, feed back into the line at 80/20 virgin powder to regrind. A couple tips if you want it to go smoother and produce more.
If you pulverise some of the regrind into a fine powder and mix with the chunkier regrind, the extruded product will be far more consistent. You can attach a magnet to the side of the hopper and that will pull out any metal before it has a chance to clog the filter. Use a blowing agent like hydraxine or similiar via a suspended dropper and you can drop the screw speed and temps to almost double your final extruded product at the cost of density. If you want to get super in the weeds then you can drill a hole near the end of the screw barrel and pull a vacuum on the melted material to effectively eliminate any contamination.

I love how you have the ability to form new mesh filters as required. The original manufacturer doesn't rip you for replacement parts.

Things to try:

- Print and recycle the same plastic a few times to see if it degrades
- Make filament from non 3d printed sources
- find a way to upgrade it or improvements for it after you use it for a bit.

I worked in a plastic recycling facility for 8 years. We did profile extrusion as well as compounding pellets. A water tank to cool the fillament after leaving the barrel and die would allow for you to drag the mix from the extruder at higher speed and keep tension on it as well instead of using gravity. This is if the setup can melt the plastic faster and not back up the barrel.

TeachingTech just released a filament shredder/chopper, which would be really useful for you to re-pelletize some first stage filament! That should give you uniform pellets that work much better for your filament extruder.

This is a HUGE step in the right direction. I've been so confused as to why there aren't any solutions to shred and re-spool 3D printing waste that are consumer grade and priced. I'd love to buy a system to recycle my PETG and PLA waste, but it's way too expensive right now.

[VacFink]

I’d love to see an experiment showing how repeated recycling affects strength and printability.

[retrohipster]

I think a big reason why I'm excited about this project is that I feel like a lot of these parts can be sourced cheap or can be sourced from old machines. Like if you had an old ender 3 floating around, you probably already have a lot of stuff for this project. This project seems like the best shot a determined maker has at making a recycling machine cheaply..

[hazonku]

I came cuz Angus told us in his annual predictions for the next year video to check this out. Was not disappointed. This thing really is amazing. Maybe not something for us hobbyists but I could see the average Etsy print farmer who has consistent business paying for one in about a year or two and then even saving money not long after.

[rafaelguida]

The amount of detail they put while keeping it low price is honestly impressive. From a mechanical intermittent reversing winder to the mixer, angle measurement in a clever way, wow! Im amazed

[williamsnapp]

I’m super impressed with this kit. I’m an engineer who used to work in bulk plastic production, so many features of a professional small scale plastic extruded are present in this inexpensive kit

[josephmoloney]

To be honest the best way I see this working is in groups of makers such as myself and a friend rather than me purchasing one for me alone

[Rancr]

I had previously extensively researched recycling 3d printing material around 2 years ago. It was a flunk. The machines were too expensive and you would never ROI your investment into one of them. Very happy things have changed, and thank you for this video.

To correct the hot filament falling off the roller, you can just print or purchase an inverted double cone shaped roller (like the ones where a cross section is two arrows pointing at each other) and the filament shouldn't fall off anymore. Might have to play around with the angle to make sure it doesn't bind or alter the shape of the filament. Might be best to just create one where it curves with the same radius as the filament so it can't physically deform the filament at all actually.

[olafmarzocchi]

If coupled with a Hall filament width sensor (see link in klipper documentation) you could use a feedback on the filament diameter and both avoid the tricky sensor at the bottom and also improve a lot the accuracy.

In fact, a video about filament dimeter compensation during printing would be interesting.

[MinecrafterPiano]

Regarding Teflon-tape temperature (6:25), some Teflon tapes are rated for 260C/500F while others are 288C/550F.
So you can bump the temperature to ~280C if you use the right tape; it's basically the same price too!

[drewmiller]

I could see this as a great option for local 3D printing groups. If ten people got together to purchase one it could be really beneficial.

@CNCKitchen Have you heard of the INFiDEL by Thomas Sanlander? Its an inline filament sensor, and if the designer of this actually added the sensor to this project, it would be more autonomous. It is capable of feedback, and He said that if someone wanted to, it could be used to have a variable extrusion rate during printing, based on the filament diameter. that basically means your filament tolerance doesn't need to be as good. Here is the video Title: Make your own inline filament diameter sensor (under $5)!
