New from Stratasys Inc. (www.stratasys.com) is a PC-ABS (polycarbonate-ABS) blend for rapid prototyping and rapid production. Combining the strength of PC and the flexibility of ABS, PC-ABS blends are most commonly found in automotive parts, electronics, telecommunications equipment, and toys. The new blend from Stratasys will help designers better predict end product performance, the company says, and it is compatible with three FDM™ systems from Stratasys: Titan TI, Vantage SE, and Vantage S. FDM, or fused deposition modeling, is designed for building prototype and production parts out of high-performance materials such as ABS, PC, medical grade Class VI PC, and polyphenylsulfone. For the new PC-ABS blend, two layer-thickness settings are available: 0.005 and 0.01 inch (0.127 and 0.245 mm).
Mechanical and Thermal Properties of Stratasys's PC-ABS
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
