  • ADDITIVE MANUFACTURING APPARATUS INCLUDING TWO LIGHT ENGINES AND A LIGHT ALTERING STRUCTURE AND A METHOD OF ADDITIVE MANUFACTURING A THREE-DIMENSIONAL OBJECT
    Publication number: 20240157642
    Abstract: The present disclosure provides apparatuses and methods for manufacturing three-dimensional objects. Each additive manufacturing apparatus (1000, 2000, 3000) includes: a) a reservoir (1100, 2100, 3100) for receiving hardenable material; b) a first movable light engine (1200, 2200, 3200) providing a first light radiation configuration; a second light engine (1300, 2300, 3300) providing a second light radiation configuration that is different than the first light radiation configuration; and d) a light altering structure (1400, 2400, 3400). The light altering structure is located between the reservoir and light radiated from at least one of the first movable light engine or the second light engine. The first movable light engine is configured to radiate light onto a first focal plane (2220) within the reservoir containing the hardenable material and the second light engine is configured to radiate light onto a second focal plane (2320) within the reservoir containing the hardenable material.

  • Coating for reducing contamination of substrates during processing
    Patent number: 7824498
    Abstract: A substrate support has a support structure and a coating on the support structure having a carbon-hydrogen network. The coating has a contact surface having a coefficient of friction of less than about 0.3 and a hardness of at least about 8 GPa. The contact surface of the coating is capable of reducing abrasion and contamination of a substrate that contacts the contact surface. In one version, the support structure has a dielectric covering an electrode. A plurality of mesas on the dielectric have a coating with the contact surface thereon.
