Abstract
The invention provides a stereo lithographic 3D printing assembly comprising a digital projection system for projecting a first pattern having a first resolution at a projection location, and a photo mask system for projecting a second pattern having a second resolution at said projection location. This provides a fast 3D printing assembly allowing high resolution details.
Claims18
A stereo lithographic 3D printing assembly comprising a digital projection system for projecting a digitally defined first pattern having a first resolution at a projection location, and a photo mask system for projecting a second pattern having a second resolution and said second pattern and said first pattern aligned with one another at said projection location.

(canceled)
A stereo lithographic 3D printing method, comprising:
- projecting a digitally defined first pattern having a first resolution at a projection location in a resin container during a stereo lithographic 3D printing process using projection optics;
- providing at least one photo mask between said a resin container and said projecting optics;
- projecting at least one photo mask pattern at said projection location using said at least one photo mask to project a second pattern having a second resolution at said projection location for providing said second pattern on said first pattern.
