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.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
