Lubrizol has developed a thermoplastic polyurethane (TPU) urethane that targets replacement of silicone in peristaltic pumps. Peristaltic pumps are positive displacement pumps used to pump a variety of fluids. A technical officer of Lubrizol interviewed at MD&M West in Anaheim, CA yesterday said that the new TPU is melt processable, unlike silicone, which is a thermoset. The new material would be one of the softest TPUs with Rockwell Hardness of 62A. The product was on display at the Lubrizol booth. Full details are expected to be disclosed at the Annual Technical Conference (ANTEC) of the Society of Plastics Engineers in Boston this May.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
