Hardware for ceramic processing using new LED based light engines - Laboratory Prototype 1st generation

The heart of the prototype is a DLP projector, consisting of a 1080p DMD chip from Texas Instruments. This chip was non-commercial at the time of the prototype’s completion. The resolution was 1920x1080 pixels. Using a high performing LED source allowed peak powers of 208,3 W/m2 at 465,6 nm dominant wavelength. Patented tilting and coating devices as well as back illumination facilitated the processing of ceramic based slurries with high viscosities (<40 Pa s). Together with a 3.704x magnification objective, a pixel size of 40x40 ?m2 and a maximum building volume of 43 x 78 x 150 mm3 was achieved. Processing speeds of up to 10 mm/h were possible.
