Printability and Surface Finish

Polycarbonate is widely used in engineering applications due to its outstanding mechanical properties, but it has traditionally been considered difficult to print. Spectrum PC 275 has been developed to improve processing stability by minimizing warping and reducing material shrinkage while maintaining the strength and durability expected from polycarbonate.

The material produces strong interlayer bonds and excellent dimensional accuracy, making it suitable for mechanically stressed components and precision applications. With proper printer settings and temperature control, users can achieve consistent, reliable results for both prototypes and production-grade parts.

Traffic Black provides a sleek, professional appearance with a glossy finish that enhances the presentation of functional components and technical projects.
