NEC will begin using a bioplastic hybrid to make housings for its personal computers this year. The move marks a major increase in its use of the materials from renewable resources. Since 2004, NEC has tested the material in “dummy cards” which are inserted in the memory card slot of a PC at the time of purchase. The NEC polymer is made from polylactic acid and kenaf fiber. NEC had hoped to introduce the material to PCs last year, but was delayed waiting for development of an environmentally safe flame retardant. Composition of the material is 90% biomass. “It is biodegradable, but the speed is considerably low because the molecular structure is modified to improve its durability,” an NEC spokesperson told Design News. The cost of the resin has been able about double oil-based plastics in the relatively small lots used so far for applications such as mobile phones. The NEC development goes way beyond technology in North America, where focus has been on disposable packaging. For example, NEC coupled the bioplastics with flame retardants made from metalhydroxides and other materials.
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.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
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.
