Polycarbonate ABS alloy (PC-ABS) is a tough thermoplastic, combining the strength and heat resistance of polycarbonate with the flexibility of ABS. Commonly found in automotive, electronics, and telecommunications applications, it is one of the most widely used industrial thermoplastics in the world.
When used as a 3D printer filament, the same benefits apply, but the trade-off is a slightly more complicated printing process. First, because PC-ABS is hygroscopic, it’s recommended to bake it before printing. Second, it requires a high printing temperature (of at least 260°C). Third, it tends to warp, so a high print bed temperature is also necessary (of at least 100°C, could be as high as 140°C).
When Should I Use PC/ABS 3D Printer Filament?
Functional prototyping, tooling and small-batch end use parts that need to withstand small shocks and impacts are a good fit for PC/ABS.
