New Technology 3D Prints Ultra-Smooth Polyurethane Parts in Single Step

Smooth-Mode technology, developed by Chromatic 3D Materials, enables 3D printing of durable rubber parts with ultra-smooth surfaces at commercial volumes. High-quality polyurethane parts, such as seals, gaskets, grommets, and bladders, can now be 3D printed without post-processing requirements or surface finishing, said the company. Sealing requires a smooth surface, but 3D-printed parts typically have layer lines or roughness. “We have developed a way to easily and cost-effectively 3D print products…

The design ensures a leak-free seal, which explains its early adoption and continued widespread use in the medical and pharmaceutical sectors. In a recently published news release, Arburg uses the venerable Luer connector to illustrate how a modern approach to integrating functions during…

Newsom Nixes Thermoform Recycling Bill

California Governor Gavin Newsom announced today that he is not signing Assembly Bill 2784, which would have established minimum recycled content in thermoform plastic containers and mandated CalRecycle to collect fees from producers whose products did not meet those requirements. Noting that he strongly supports California’s transition to a circular economy, Newsom wrote in his statement that AB 2784 imposed “confusing requirements” in conflict with some provisions of SB 54,…
