Topic: Polycarbonate!

( I also posted this in the DIY Filament materials thread, but i felt it was appropriate to post it here too. If it is inappropriate to double post this way please tell me.)

I set my Filastruder to 250, but I could only do about 230 with the motor running on the same power supply as the heater band. I also had a fan blowing near, but not on the nozzle to push away the "off-gas" (I think this is the correct term)

Okay, so i tried extruding it yesterday and here are my results:
The surface of the PC was rough, and the diameter was about 1.10-1.12 with the winder. Occasionally the filament would have a bubble in it. If you add and additional fan, and put the motor on a separate power supply, I am almost positive you could do 1.75 with good tolerances.

Any questions or feed back?

Re: Polycarbonate!

So are you going to try with a better power supply smile?


Sounds like you need more heat, or better insulation. 


Another option is PC-ABS blends. I forget the common ratios, but the make a great co-polymer. Sorta a co-co-polymer since ABS is already a blend.
