Vancouver, British Columbia – Two new polyurethane based resins are being developed by 3D printing specialist Carbon.
“We want to extend engineering-quality material families to many industry-specific production formulations,” Jason Rolland, the company’s vice president of materials, told attendees at the Polyurethane Manufacturers Association in Vancouver, British Columbia.
The first of these, SIL 30, is a silicone–urethane. It is designed to be both soft and tear resistant, and will be equivalent to thermoplastic silicone–urethane materials. Applications include products such as earbuds and other consumer electronics, wearables, gaskets and seals.
A clear rigid polyurethane (RPU) is being developed, in response to customer requests. This will allow rigid parts, such as those required for microfluidics, to be created very accurately. Also under development is an ultra-high impact FPU resin. This has been designed to withstand cold cycling and fatigue, as well as give a very high impact strength value.
