Microfabrication process
Projection micro-stereolithography exposes patterned resin layers. The published optical resolution, positional accuracy and part tolerance describe different performance measures.
Material handling
The system includes a heated vat, coated build platform and side-shifting membrane. Optional small-volume vats support material development, while touchscreen parameters can be customized.

The reviewed S150-series specification table states an 80 × 48 × 50 mm print size. Optical resolution, motion accuracy and printed-part tolerance are separate measurements. S150 Ultra is a separate configuration; a launch date remains unverified.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
