    Abstract: A system for additive manufacturing uses a pulsed laser beam with one or more low flux components on the order of kW/cm2, and one or more high flux components on the order of MW/cm2 during the duration of the pulse. The pulsed laser beam is directed onto the powder particles on the substrate thereby melting the powder particles and melting the substrate at the interface layer between the powder and the substrate such that the powder particles bond to the substrate. This is accomplished by using low power (and low cost) lasers to do the majority of the energy transfer, and using high power (and higher cost) lasers to complete the melting process, overcoming the kinetics of powder agglomeration through surface tension forces by partially melting the powder-substrate interface layer before surface tension can take effect on the molten powder particles.

  • Patent number: 10369745
    Abstract: The present invention relates to a membrane and a method for manufacturing a membrane for filtering a fluid, said membrane comprising: a substrate having a three-dimensional structure and consisting of an one-piece ceramic porous body; and at least one separating filtering layer having a porosity that is lower than that of the substrate, in which the three-dimensional structure of the substrate is produced by forming elemental layers that are stacked and connected in series with one another, by repeating steps: a) depositing a continuous bed of powder at least partially consisting of a powder intended for forming the ceramic porous body; b) locally consolidating, part of the deposited material such as to create the elemental layer, and simultaneously linking the elemental layer thus formed with the preceding layer such as to gradually grow the desired three-dimensional shape.

  • Patent number: 10343389
    Abstract: The present invention is directed to an improved method for supporting an object made by means of stereo lithography or any other rapid prototype production method. The generation of the support begins by determining the region that requires support in each layer of the object and defines a number of support points in this region. In a next step, a support mesh is generated connected to the object using these support points. The present invention also discloses different techniques that reduce superfluous edges to further optimize the support mesh. Finally, a support is generated from this support mesh. The present invention may facilitate the generation of supports data by employing more automation and less user analysis.

  • Patent number: 10330699
    Abstract: A device comprises elements for measuring current, the elements being housed in a casing. The casing includes a first portion and a second portion made of plastic, welded to each other, which together define a housing for receiving the measuring elements. The first portion is opaque in order to absorb a laser beam for welding the portions, and the second portion is transparent in order to let the laser beam pass. The process for manufacturing the device includes a fitting step in which the measuring elements are fitted into the casing and an assembly step in which the portions of the casing are joined together using a laser welding process.

  • Patent number: 10265769
    Abstract: A three-dimensional fabricating apparatus includes a fabrication chamber, a supply chamber, a flattening unit, and a controller. In the fabrication chamber, powder is layered to form a powder layer and bonded together in a desired shape to form a layered fabrication object. The supply chamber stores the powder. The flattening unit is reciprocally movable above the supply chamber and the fabrication chamber, to transfer the powder and flatten the powder in the fabrication chamber to form the powder layer. The controller is configured to control the flattening unit to move in a first direction to transfer and supply the powder from the supply chamber to the fabrication chamber. The controller is configured to control the flattening unit to move in a second direction opposite the first direction to form the powder layer and transfer an unused portion of the powder from the fabrication chamber to the supply chamber.
