The giant Solvay Group, based in Brussels, is making a major bet on the plastics electronics business. Most recently, Solvay North America Investments led a $20.6 million financing round in which it bought a minority interest in Plextronics, a Pittsburgh-based company that has new conductive plastics technology. Plextronics envisions 15 billion printed electronic devices by 2015, using new technology developed by a Carnegie-Mellon professor that is capable of commercial scale performance. That’s where Solvay may become particularly interesting. Right now, Plextronics has no polymer manufacturing capability. Solvay has plenty, particularly in very high performance plastics. It’s too early to say now if Solvay may help in actual polymer production.
One of the goals is to produce flexible solar cells that could significantly reduce the cost to produce power from solar cells. Another potential market is printed Organic Light Emitting Diodes displays that could challenge plasma technology and liquid crystal displays. Another possible application is RFID tags.
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.
