Polymaker, a filaments supplier for extrusion-based desktop 3D printers, has co-developed with Covestro a new line of polycarbonate (PC)-based materials for these printers.
The first two products in the new line are Polymaker PC-Plus and PC-Max. The application was made possible by lowering the printing temperature from 300-320°C down to a moderate 250-270°C as well as by a significantly reduced tendency to warping.
Compared with existing 3D printing materials, Polymaker PC is said to offer high heat resistance of over 100°C, making them suitable for lighting, engineering and all types of applications that require good structural stability when exposed to heat.
In addition, Polymaker PC-Max further exhibits improved mechanical properties – increased toughness, in particular for mechanically demanding applications.
To date polycarbonate has only been available for applications in exclusive, industrial 3D printers or a small market for extrusion-based 3D desktop printers.
“Thanks to Covestro’s experience, portfolio of products and industry leadership, we can achieve high performance, reliability and safety with the best materials,” said Dr. Luo Xiaofan, CEO of Polymaker. “The products should inspire our customers and expand our portfolio.”
Polymaker PC can easily be post-processed by sanding, coating or other methods. Additional advantages include intrinsic flame retardance, optical transparency and resistance to chemicals and solvents, added Covestro.
Tim Efthimiady, Senior Vice President of the Polycarbonate Business Unit of Covestro, noted: “We see the introduction of our high-tech polymers to the field of 3D printing as an important step for driving next-generation design and production solutions. We are looking forward to further collaboration with Polymaker for this burgeoning industry.”
