MakerWare Profiles for Polycarbonate on an R2x

thingiverse

This text presents MakerWare profiles for Polycarbonate (PC) printing on a Replicator 2x. PC has similarities with T-glase, being crystal clear but twice as strong and tough as ABS while stiffer than nylon. Suitable for mechanical use up to 150°C, it's prone to warping like ABS. Printing PC requires high-temperature setup, preferably all-metal, as stock R2x parts are not heat resistant. The text suggests specific components and settings like Carl's T-shaped heater block, DHeadrick's aluminum 3in1 extruder, and 0.5mm nozzle from QU-BD. Print settings include 0.5mm layer width, 0.3mm layer height, 265°C nozzle temp, 130°C HBP temp, 30-60 mm/s print speed, and warping prevention techniques. It's also crucial to dial in print settings on a calibration cube before attempting real prints due to PC's strong nature and inability to be dissolved by solvents like ABS.
