  • Patent number: 10449632
    Abstract: An additive manufacturing system wherein a gentle sintering run on heat-fusible particles is followed closely by a selective laser melting run. The laser sintering run slightly sinters the particles and causes the particles to adhere to each other, but not necessarily deform and lose their original shape. The particles become connected via bridges between each other, which holds them in place. During the laser melting run, the powder melts in place, with minimum particle ejection or mobility, since the particles form a network of connected particles.

  • Patent number: 10189033
    Abstract: A process and apparatus are disclosed for the deposition of a layer of a first material onto a substrate of a second material. Powder particles of the first material are entrained into a carrier gas flow to form a powder beam directed to impinge on the substrate. This defines a powder beam footprint region at the substrate. The powder beam and the substrate are moved relative to each other to move the powder beam footprint relative to the substrate, thereby to deposit the layer of the first material. A laser is operated to cause direct, local heating of at least one of a forward substrate region and a powder beam footprint region. The laser beam direction is defined with reference to a plane coincident with or tangential to a surface of the substrate at the center of the laser beam footprint in terms of an elevation angle from the plane to the laser beam direction and in terms of an acute azimuthal angle from the movement direction to the laser beam direction.

  • Patent number: 10046394
    Abstract: A method for manufacturing material voxel-by-voxel using directed-energy deposition is given. Using the method, unsupported structures, via voxel-wise directed-energy deposition, with steep overhangs is described and demonstrated. Methods for forming arbitrarily-complex structures and shaped voxels and surfaces are also given. A method for forming materials with internally-varying properties is also given. The method utilizes a pulsed or modulated, rather than continuous-wave energy source, thus allowing rapid solidification of voxels, rather than contours, hatches or tracks. Tuning of pulsing or modulation, material flow, and deposition-path parameters allows the buildup of unsupported material using standard directed-energy deposition processing heads and 3-axis stages, for example. The methods are demonstrated using a modified-directed-energy-deposition processes and is applicable to powder-bed for the buildup of three-dimensional components, repair and the addition of features to existing components.

    Abstract: A fabrication resource receives a base material such as metal or other suitable material. The fabrication resource applies optical energy to a surface of the base material. Application of the optical energy transforms a texture on the surface of the base material. Subsequent to transforming the texture on the surface of the base material, the fabrication resource then adheres a supplemental material such as paste including glass powder to the transformed texture on the surface. Application of heat to the paste fuses the glass powder of the applied paste into a glass layer that adheres to the transformed texture. The fabrication resource contacts an electronic circuit device onto an exposed facing of the glass layer and reheats the combination of the electronic circuit device, glass layer, and base material. The application of heat secures the electronic circuit device to the layer of glass and corresponding base material.

  • Publication number: 20150064363
    Abstract: An atmospheric, Laser-based Chemical Vapor Deposition (LCVD) technique provides highly localized deposition of material to mitigate damage sites on an optical component. The same laser beam can be used to deposit material as well as for in-situ annealing of the deposited material. The net result of the LCVD process is in-filling and planarization of a treated site, which produces optically more damage resistant surfaces. Several deposition and annealing steps can be interleaved during a single cycle for more precise control on amount of deposited material as well as for increasing the damage threshold for the deposited material.

  • Patent number: 8962098
    Abstract: The objective of the present invention is to provide an unexpected method of manufacturing a battery electrode and a coating die for use therein, both of which are capable of providing a high speed drying and of improving a peel strength between a collector and a compound. The manufacturing process S1 of manufacturing the battery electrode 1 includes the process of coating the compound 3 containing the electrode active material 4 and the binder 5 on the sheet collector 2 and the process of drying the compound 3 to bond the collector 2 and the compound 3, wherein in the coating process, a laser light is emitted to the interface between the compound 3 and the collector 2. Due to the above structure, regardless of the drying speed, the binder 5 contained in the compound 3 is crystallized at the interface with respect to the collector 2. As a result, the high speed drying is provided and the peel strength between the collector 2 and the compound 3 is improved.

  • Publication number: 20150037513
    Abstract: High rate deposition methods comprise depositing a powder coating from a product flow. The product flow results from a chemical reaction within the flow. Some of the powder coatings consolidate under appropriate conditions into an optical coating. The substrate can have a first optical coating onto which the powder coating is placed. The resulting optical coating following consolidation can have a large index-of-refraction difference with the underlying first optical coating, high thickness and index-of-refraction uniformity across the substrate and high thickness and index-of-refraction uniformity between coatings formed on different substrates under equivalent conditions. In some embodiments, the deposition can result in a powder coating of at least about 100 nm in no more than about 30 minutes with a substrate having a surface area of at least about 25 square centimeters.
