Newly developed selective self-adhesive silicone rubbers can be co-molded with nylons, polycarbonates, and PBT-type polyesters, creating new design opportunities in medical devices and cars. “These materials can eliminate assembly operations for needle-less IV valves,” comments Eric Bishop of Shin-Etsu Silicones. The new materials’ combinations are also replacing gum rubber in automotive applications. Bishop spoke at Molding 2008 in San Francisco. The materials are called selective because they don’t adhere to steel.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
