[Ondřej Šraitr] has quite a few video clips, which includes the a person you can observe underneath, about his PETamentor2 — a device for turning PET bottles into printable filament. You can get the information on Thingiverse, and there are not many parts you have to buy.
The device seems superior, and from the videos, it appears to perform properly. A blade slices the bottle into a strip that feeds what is essentially a hot conclude that pushes out the filament. The blade is adjustable to set the amount of money of plastic fed at any provided time which is critical because you need plenty of to make a solid piece of filament but not any a lot more than that.
Amazingly, the monthly bill of elements doesn’t incorporate any kind of microcontroller. There is a PWM velocity regulate module to push the 7 RPM motor and a temperature controller. Of class, you have to have a electric power supply, 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 takes care of getting to the remaining 1.75 mm sizing.
It can take about 45 minutes to take in up what looks like a 1-liter bottle. The filament created appears fantastic in the online video. We aren’t certain, but we think that was a roll of solder made use of as a ballast weight on major of the bottle trying to keep it transferring in a downward course. Bottles indicate wetness, of program, so immediately after developing the filament, it requires to be dried.
This is the 2nd version of the equipment and we were being a little bit surprised that we never ever observed a online video of the filament in use. But it appears to be like like it would operate and it is not like we have not found this strategy used before. In actuality, we’ve seen it a number of periods. We can not bear in mind any that appeared as fashionable as the PETamentor2, even though, and we are interested to hear about anyone’s success with the resulting filament.
