Hardware for ceramic processing using new LED based light engines - Laboratory Prototype 2nd generation

A new equipment with extended build volume was developed. Several components of the system had to be adjusted or redesigned in order to fulfil the new requirements. A series of changes in the structure of the DLP system and improvements to the 1st prototype (Figure 15) led to the concept illustrated in Figure 16. Due to the lack of space, the coating system had to be changed to a linear one. All components were adapted to meet high stiffness requirements of the extended build-volume. VIS delivered a light engine based on a WUXGA DMD with a resolution of 1920x1200 pixels. For focusing, optics with bigger magnification ensured a 3 times larger X-Y- building volume of 115.2 x 64.8 x 160 ?m3 was achieved. Building speeds of upt to 8 vertical mm/h could be obtained.
