® RenShape <strong>SL7840</strong> <strong>Resin</strong><br />
The SL resin you envision:<br />
white, accurate, durable and PP-like<br />
Key features<br />
> PP-like fine surface parts with<br />
high elongation and excellent<br />
flexibility<br />
> Good dimension stability even<br />
in humid conditions<br />
> Low viscosity supports easy<br />
recoating during the build as<br />
well as good drainage for fast<br />
and easy cleaning<br />
> Good green strength requires<br />
minimal finishing<br />
stereolithographY From<br />
Key benefits<br />
> Users can build accurate, robust<br />
parts in PP-like pearl white color<br />
> Throughput is increased with<br />
minimal part finishing<br />
> Because the liquid resin is<br />
colorless clear and the cured<br />
resin becomes pearl white in<br />
its appearance, the parts are<br />
distinctly recognizable during<br />
the build<br />
Key applications<br />
> Designed for use on solid state<br />
SLA ® platforms<br />
> It offers a large working envelope<br />
of buidling concept models<br />
and functional prototypes where<br />
snap-fit property is required
