 How
SLA process works: Stereolithography
process produces plastic parts directly from 3D CAD model; by solidifying
the surface of a liquid photo polymer layer by layer with the help
of a laser beam. When the laser beam hits the liquid, it solidifies
the resin. When a layer is fully traced, the elevator is then lowered
in the vat. The self-adhesive property of the material causes the
layer to stick with each other and in this way a 3d part is formed
in multi-layers. SLA process is very accurate and suitable for smooth
surface finished parts. These parts are widely used for conceptual
designs, Product verification, Pattern making, Form/Fit analysis and
light functional testing.
