Japanese OEMs, particularly in the electronics and IT fields, are leading the way on engineering applications for plant-based plastics. The latest: Fujitsu is testing a new polymer that uses caster oil extracted from the seeds of the caster bean. The new polymer is being tested for small components in notebook PCs and for mobile phones. A target application is connector covers. Five years ago, Fujitsu was one of the pioneers, using polymers based on corn-based polylactic acid in the chassis of a notebook PC. The goal of the new polymer, developed with Arkema, is better flexibility.
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.
