The Viper

Pro SLA
®
system is a 3-D Production Solid Modeler that generates plastic models or
prototype parts from computer data. The system typically builds parts by processing a three-
dimensional CAD file. Software translates the CAD data to represent cross sections, or slices.
The Viper Pro SLA system creates models by profiling each slice as a layer on the surface of a
resin delivery module (RDM) that contains resin. Layer thickness can range (see the
for details).
A laser beam solidifies the layer of resin. The vertical elevator system lowers the newly formed
slice beneath the surface of the resin at a distance determined prior to part building. A recoating
system ensures consistent layer thickness. Layers build up until all the data for the model is
processed. Then the part is drained and removed from the Viper Pro SLA system for post-
processing. The Viper Pro SLA system consists of an assembly of numerous discrete sub-systems
that are integrated to perform 3-D stereolithographic model generation. The subsystems are
combined into a single physical unit.
