STEREO LITHOGRAPHIC 3D PRINTING ASSEMBLY AND STEREO LITHOGRAPHIC3D PRINTING METHOD

摘要

The invention provides 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, said photo mask system providing at least one photo mask between said digital projection system and said projection location. This provides a fast 3D printing assembly allowing high resolution details.
