  • Patent number: 8926304
    Abstract: A three-dimensional printing apparatus including a tank filled with a liquid-state forming material, a platform disposed at the tank, a rotating shaft, a rotating arm, and at least one light source is provided. The rotating shaft is disposed under the tank or above the tank. The rotating arm connects to the rotating shaft such that the rotating arm is driven by the rotating shaft to rotate. The light source disposed on the rotating arm rotates along with the rotating arm and generates light projecting toward the forming material along with the part of the platform moving in the forming material, such that the forming material is solidified in layers and forms a three-dimensional object on the platform.

    Abstract: A continuous-wave (CW) ultraviolet (UV) curing system for solid freeform fabrication (SFF) is provided, wherein the curing system is configured to provide an exposure of UV radiation for one or more layers of UV-curable material. One or more UV exposures may initiate curing of a curable material in the layer dispensed by a solid freeform fabrication apparatus. One approach to provide the single or multiple UV exposures is the use of one or more UV LEDs, which generate UV radiation without generating any substantial amounts of infrared (IR) radiation at the same time. This allows for the curing process to be energy efficient and also allows for the SFF system to be far less complex.

  • Publication number: 20140314995
    Abstract: A method of pulsed laser processing of solid surface for enhancing surface hydrophobicity is disclosed wherein the solid surface is covered with a transparent medium during laser processing and the laser beam incidents through the covering medium and irradiates the solid surface. Two effects are obtained simultaneously. One is the laser-induced texture formation directly under the laser irradiation. The other is the deposition of the laser-removed materials along the laser scan lines. Both effects introduce surface roughness on nanometer scales, and both enhance surface hydrophobicity, rendering superhydrophobicity on the surfaces of both the laser-irradiated solid and the covering medium. Because the beam scan line spacing can be larger than a single scan line width by multiple times, this method provides a high processing speed of square inch per minute and enables large area processing.

    Abstract: A powder bed laser sintering (PBLS) device includes a build chamber having a build area defined over a build plate. The build area is bounded by a plurality of walls comprising first and second end walls and first and second side walls extending between the first and second end walls. The build plate is movable relative to the plurality of walls to successively lower in stages. Powder material is layered into the build area at each stage and is selectively subjected to a laser beam to fuse the powder material to form an additional layer of a component at each stage. A powder dam extends between the first and second side walls through the build area. The powder dam holds the powder material between the powder dam and the first end wall.

The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

  • Patent number: 8852491
    Abstract: In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.
