STUNNING PARTS
THAT ALWAYS FIT WITH A SURFACE FINISH THAT RIVALS INJECTION MOLDING.

Sharpest details: highly collimated light with
pre-tuned anti-aliasing for subpixel resolution.
Smoothest surfaces: lower peel forces and
light touch supports.
Most accurate assemblies:
±0.15% XY dimensional tolerances so
assemblies always fit.
