Materials Engineering: Glass-Clear Prototypes are Tough as Nails
Rapid prototypes made from Ren- Shape SL 7870 look like glass.
But
with a notched Izod impact strength
of 1.15 ft-lb/in., a 286 to 333-ksi flexural
modulus, and a 10 to 22% elongation,
they reportedly take more of
a licking than competing clear stereolithography
(SL) materials. The SL
7870 photopolymer also maintains
long-term dimensional stability in
warm/humid (40C and 90% R/H)
environments. The low-viscosity
material joins a family of antimony free
RenShape photopolymers from

It also is a

for parts

high-quality,
smooth surface
finishes
and a precise
replication
of intricate
