Polymaker, a leader in advanced 3D printing materials, announces the launch of three new polycarbonate-based 3D printing materials. Each has unique properties that are commonly used in different industries. Polymaker has partnered with Covestro to bring these new materials to market, providing access to products already known to professionals and optimized for 3D printing.

The three new materials consist of:

- Polymaker™ PC-ABS - a mixture of already common 3D printing materials, polycarbonate and ABS. The advantages of this blend are impact resistance, heat resistance and ease of processing. The polycarbonate increases the heat resistance and hardness of the material, while the ABS contributes to the good processing properties. This PC-ABS also specializes in surface finishing, for example electroplating and metallization, and provides a good approach for finishing.

Polymaker™ PC-ABS uses the Bayblend® range from Covestro as a starting material, a plastic commonly used in the automotive and information technology industries today. Polymaker™ PC-PBT - this polymer blend combines the good chemical resistance of PBT with the strength and toughness of polycarbonate. Polymaker™ PC-PBT is also suitable for use in extreme conditions, whether in contact with hydrocarbon-based chemicals or at temperatures below zero. The product retains its good toughness and natural ductile fracture behavior even at low temperatures.

- Polymaker™ PC-PBT was developed from Covestro's Makroblend® family, which is widely used in various industries. Compared to PC resins and PC-ABS compounds, PC-PBT is more resistant to chemicals. This enables printed applications where good resistance to temporary contact with fuels, oils, lubricants and cleaning agents is required.

- PolyMax™ PC-FR is based on Covestro's Makrolon® family of flame retardants, the main feature of this polycarbonate-based blend. This base material achieves V0 performance in the UL94 flame retardant test and benefits applications where appropriate material approval is required. In this way, PolyMax™ PC-FR can be used for battery housings, engine mounts in aerospace and other industries. Such FR materials are well established in the automotive, electronics and electrical industries.

Polymaker has introduced a nano-reinforcement technology that is included in all PolyMax™ materials. This increases the fracture toughness of the FR material and produces a flame retardant filament suitable for demanding applications. PolyMax™ PC-FR is based on Covestro's Makrolon® and offers a balance between mechanical performance and safety, as it has been used in electronic motorcycles, aerospace and automotive spare parts.
