PC-ABS for Fortus 3D Production Systems

PC-ABS (polycarbonate-ABS) is one of the most widely used industrial thermoplastics. PC-ABS offers the most desirable properties of both materials – the superior strength and heat resistance of PC and the flexibility of ABS. PC-ABS blends are commonly used in automotive, electronics and telecommunications applications. Additionally, a PC-ABS part manufactured on a Fortus® 3D Production System is 5-60 percent stronger than a part made on previous FDM® systems. When combined with a Fortus system, PC-ABS gives you Real PartsTM conceptual modeling, functional prototyping, manufacturing tools, and end-use-parts.

The information presented are typical values intended for reference and comparison purposes only. They should not be used for design specifications or quality control purposes. End-use material performance can be impacted (+/-) by, but not limited to, part design, end-use conditions, test conditions, color etc. Actual values will vary with build conditions. Product specifications are subject to change without notice.

1 Build orientation is on side long edge.
2 Literature value unless otherwise noted.
3 Due to amorphous nature, material does not display a melting point.
4 All Electrical Property values were generated from the average of test plaques built with default part density (sparse). 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.
