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.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
