Somos®WaterShed is an equivalent solution for material needs
such as ABS and PBT. The clear resin is optically approved.
It helps shorten the product development and testing process.
With these features, Somos®WaterShed; in areas such as
automotive, aerospace and consumer electronics; it is frequently
preferred in applications such as precision casting models.

Stereolithography
The best solution for

smoot surface quality
In SLA printing technology, the photopolymer resin
is cured with a UV laser source. This technology requires
support structures which are removed after printing.
It is a frequently preferred printing technology for parts
which need high accuracy and smooth surface quality.
SLA parts can be finished a very high standard using
a variety of post-processing methods such as sanding,
painting and varnishing.
