used to fabricate large, 3D objects with complex shapes via tradi-
tional casting or injection molding techniques. Moreover, the chi-
tosan bioplastic breaks down within about two weeks when returned
to the environment, and releases rich nutrients that efficiently sup-
port plant growth. For more information: Javier Fernandez, javier.

Platinum chromium coronary stent system
Boston Scientific, Natick, Mass., received CE Mark approval for
its next-generation bare metal stent, the REBEL platinum chromium
coronary stent system, designed to treat coronary artery disease. The
system offers physicians the same platform as the Promus PREMIER
drug-eluting stent, but without the Everolimus drug. The cus-
tomized platinum chromium alloy stent features high visibility, low
recoil, exceptional radial strength, and fracture resistance, while im-
proving axial strength and deliverability. The enhanced low-profile
delivery system includes a shorter, more visible tip, unique dual-layer
balloon, and a Bi-Segment inner lumen catheter, which provides an
appropriate level of pushability and flexibility. The stent system is
available on a Monorail platform in 48 sizes, ranging in diameter
from 2.25-4.50 mm and lengths of 8-32 mm.

ADVANCED MATERIALS & PROCESSES • MAY 2014 11
A new book from SAE International, Warrendale, Pa., Plastics
Application Technology for Safe and Lightweight Automobiles, cov-
ers application technology development for various aspects of au-
tomotive design—concept design, CAD modeling, predictive
engineering methods through CAE, manufacturing method simula-
tion, and prototype and tool making. The book describes the design
and manufacturing aspects of energy absorbers, fenders, front-
end modules, instrument panels, steering wheels, head lamp as-
semblies, throttle bodies, polycarbonate glazing, tailgates, and
exterior components such as roof racks, wipers, door handles, and
rearview mirror assemblies using engineering thermoplastics for
safety and reduced weight for next-generation automobiles.
Kaiser Aluminum Corp., Foothill
Ranch, Calif., and The Boeing Co.,
Seattle, formed a closed-loop scrap re-
cycling program that is expected to in-
volve approximately 22 million lb of
aluminum in 2014-2015.The program
is the largest aluminum recycling pro-
gram to date and captures 7XXX and
2XXX aluminum alloy recyclables gen-
erated at multiple Boeing facilities dur-
ing production of commercial aircraft.
Scrap alloys will be remelted and used
to produce aerospace sheet and plate
at Kaiser’s Trentwood facility in
Spokane,Wash
