PETamentor2 Is Latest To Turn Bottles Into Filament

[Ondřej Šraitr] has various videos, together with the one particular you can view below, about his PETamentor2 — a machine for turning PET bottles into printable filament. You can seize the documents on Thingiverse, and there are not many sections you have to acquire.

The system appears excellent, and from the video clips, it seems to perform well. A blade slices the bottle into a strip that feeds what is in essence a scorching finish that pushes out the filament. The blade is adjustable to established the amount of plastic fed at any provided time which is vital because you require adequate to develop a sound piece of filament but not any much more than that.

Remarkably, the monthly bill of supplies does not incorporate any sort of microcontroller. There is a PWM speed regulate module to generate the 7 RPM motor and a temperature controller. Of study course, you have to have a electricity source, a heater block and a heater. The nozzle is, oddly sufficient, a common .4 mm nozzle. You drill it out to 1.5 mm and die swell requires treatment of obtaining to the closing 1.75 mm size.

It can take about 45 minutes to consume up what appears to be like a 1-liter bottle. The filament made looks superior in the video clip. We are not positive, but we feel that was a roll of solder utilized as a ballast body weight on major of the bottle trying to keep it relocating in a downward way. Bottles imply wetness, of system, so just after producing the filament, it requires to be dried.

This is the second model of the equipment and we ended up a little bit amazed that we under no circumstances noticed a video clip of the filament in use. But it appears like it would operate and it isn’t like we haven’t witnessed this approach utilised right before. In actuality, we have found it many occasions. We simply cannot bear in mind any that seemed as classy as the PETamentor2, however, and we are fascinated to hear about anyone’s effects with the ensuing filament.
