The superior strength and heat resistance of PC and the flexibility of ABS.
PC-ABS (polycarbonate-ABS) is one of the most widely used industrial thermoplastics. PC-ABS blends are commonly used in automotive, electronics and telecommunications applications. Parts are ideal for conceptual modelling, functional prototyping, manufacturing tools and end-use-parts.
PC-ABS also exhibits excellent feature definition and surface finish. Engineers and designers use PC-ABS in demanding applications like power-tool prototyping and industrial equipment manufacturing. 3D printing in real engineering thermoplastics results in stronger parts, more confident testing and prototypes that mimic the material properties of the final product. PC-ABS works with soluble support material, meaning support removal is hands-free and complex parts with deep internal cavities take no extra effort.

2. Due to amorphous nature, material does not display a melting point.
3. All Electrical Property values were generated from the average of test plaques built with default partdensity (solid). Test plaques were 4.0 x 4.0 x 0.1 inches (102 x 102 x 2.5 mm) and were built both in the flat and vertical orientation. The range of values is mostly the result of the difference in properties of test plaques built in the flat vs. vertical orientation.
