Chinese language 3D printing supplies firm Polymaker has introduced the launch of three new polycarbonate (PC)-based supplies for 3D printing. Every of the supplies have been developed in collaboration with Covestro, a German producer of high-performance polymers, and are designed to comprise particular properties to be used in quite a lot of industries, like automotive, aerospace and electronics.
Utilizing formulations already well-known to business professionals, PC-ABS, PC-FR and PC-PBT, the plan is to optimize the recipes for 3D printing and convey them to market.

Optimizing Covestro polycarbonate supplies for 3D printing
Polymaker PC-ABS is a extremely processable materials, mixing collectively polycarbonate and ABS properties, and utilizing Covestro’s Bayblend method as the bottom materials. The polycarbonate content material offers the tip materials a lift in warmth resistance and toughness, whereas the ABS improves influence resistance and circulation traits. Bayblend from Covestro is a line of polycarbonate plastic supplies generally used within the automotive business, and can due to this fact assist familiarize the Polymaker PC-ABS materials to automotive engineers.
Polymaker PC-PBT was created utilizing Covestro’s Makroblend household of polycarbonate supplies, that are catered in direction of offering excessive chemical resistance, enabled by the properties of PBT. Polymaker PC-PBT is suited in direction of use within the electronics business as a defend or housing materials, because it performs nicely in excessive environments, whether or not in touch with chemical substances or working at low temperatures. Reportedly, PC-PBT is ready to function in temperatures as little as -30°C, while sustaining 70 p.c of its mechanical properties. It’s immune to a listing of chemical substances, together with hydrocarbons, alcohols, natural acids, inorganic aqueous salts & gentle base and acid options.
The primary characteristic of the third materials, the PolyMax PC-FR, lies in its flame retardant properties. It’s designed to be used in excessive warmth functions the place materials compliance is important, having achieved a V-Zero ranking on the UL 94 plastics flammability normal check. V-Zero implies that the fabric was capable of cease burning after 10 seconds, inside the circumstances of the check. PolyMax PC-FR makes use of Covestro’s Makrolon mix, a excessive efficiency plastic utilized in digital motorbikes, aerospace spare elements, and automotive manufacturing. Polymaker has additionally built-in the nano reinforcement expertise of its Polymax materials line to spice up the fracture toughness of the flame-retardant filament, permitting it to carry out in demanding functions.

Polymaker and Covestro
Polymaker and Covestro have a longstanding partnership, having helped one another to provide a variety of supplies over time. Polymaker’s PC-Max filament, launched in 2016, was developed with Covestro’s uncooked polycarbonate resins. The three new PC filaments additionally use Covestro’s polycarbonate plastic resins as their base supplies.
Moreover, In December 2017, Polymaker launched the U1000 and U0174D supplies for FFF 3D printing utilizing Covestro’s thermoplastic polyurethane (TPU) resins.
The 2 corporations have additionally launched a web site designed to assist using polycarbonate in 3D printing. It provides helpful data on 3D printing with polycarbonates – from materials choices to printing circumstances.
