- A few things to note. I have this problem where I say moon or semi moon and what I actually refer to is the filament that is extruded as a full tube or a half tube. Anyhow...I DID A THING! In the last video we finished installing the Polyformer and in this one we fine tune it until it works...Which took a bit of time...But it worked out eventually!
Skip to the end for some tips on printing with rPET I've learned.

For a small scale filament making machine, a hot end with a very large nozzle is an interesting alternative to the compression screw designs.
I would recommend drying the recycled filament in a dryer/oven/food dehydrator 70c for 3-5h to reduce the moisture content. This will help with the bubbles and the stringing. Keep it up :)!
i second this, PET tends to be very hygroscopic, and the bubbles are likely trapped steam.
I admire your persistence!!!
ill be watching you from now on, keep it up!
that’s neat, I suggest you never mix nozzles with different plastics, so for example you have the PLA-only nozzle, the ABS-only nozzle etc. otherwise you’ll always get clogging because some plastics get burned at certain different temps, and then clog the nozzles
Haha I won't mix them in the future I think. From this whole process I think I've learned my lesson 🥲
Congratulations, friend! I am printing the pieces to build the machine myself. I'm not very handy, so I hope it doesn't give me too many problems. I couldn't understand your entire video because I don't know much English, but I saw that you had quite a few issues.
Regarding the bubbles, what is the extrusion flow rate in your slicer? Normal filament is solid but PET is hollow and so it has less mass. To compensate, most people set the flow rate in their slicer to 130-140%. Under normal circumstances that may be insane but due to the hollow filament it may be necessary if you haven't tried that already.
May try in the future 👍
The one problem that home filament recycling still needs to solve is how to make filament longer than one bottle.
While it's amazing to turn a simple bottle into printable filament, there's only so much you can do with a bottle worth of filament.
I've seen a couple people attempt to build filament splicers, but I've not seen a successfully working design yet.
If that part could be solved, people could finally make an entire spool of bottle filament. THAT would be a huge step for the process as a whole.
There are 5 liter bottles :)
@@antonkukoba3378you could also do tons of water bottles and weld the filament together
Your cat's name is Aslan? That's Awwwwesome.
I wonder if PET and PETE and PETG can be combined onto the same filament spool? let me go try to google the melting point for each.
what model Prusa is that? i3 mk3?
Where can I find the updated guide and components please? What software do I need?

Where to find schematic for that filament maker?
Google: Polyformer
This whole thing is example of not so eficient design, badly documented proyect with lot of incompatible parts for diferent versions. Amount of filament needed too print all of this parts is also significant. All in all there is many ways too make more efficient and simple PET recycler.
Pfft yeah right name one
