Re: Polycarbonate printing - 13 years ago
Polycarbonate has the same shrink factor as ABS at 0.007inch per inch (or mm per mm), so I don't see why it would warp any more. In comparison, HDPE and PP can shrink up to 2% - very huge! To run PC you would need to modify (or severely alter) most of the extruder / hot ends available in order to boost the heat high enought run it. PC/ABS on the other hand could be run at about 25-35 degrees C hoby TreaterBot - Polymer Working Group
