PC-ABS
Polycarbonate-ABS Alloy is an incredibly tough material designed for strong, resilient parts. Properties are excellent and greatly improved over standard ABS.
PC-ABS is moisture sensitive. Even when stored in a bag with desiccant, drying in an oven for ~ 1hr at 85C-95C may be required for bubble free high strength prints.
good results are achieved when printing small parts at 270-290C on a heated bed at 110C up to 140C. For larger prints with good layer adhesion and minimal distortion, an enclosure is ideal.
