  • Patent number: 10960605
    Abstract: A dispensing system for an additive manufacturing includes a powder source that contains powder to form an object, and an array of nozzles positioned at a base of the powder source over a top surface of a platen where the object is to be formed. The powder flows from the powder source through the nozzles to the top surface. A respective powder wheel in each nozzle controls a flow rate of the powder. Each wheel has multiple troughs on surface of the wheel. When a motor rotates the wheel, the troughs transport the powder through the nozzle. The rotation speed of the wheel controls the flow rate. For solid parts of the object, the wheel rotates and allows the powder to be deposited on the top surface. For empty parts of the object, the wheel remains stationary to prevent the powder from flowing to the surface.

  • Patent number: 10940613
    Abstract: The present subject matter claims a process and apparatus for forming, crystallizing and increasing the molecular weight of polymer particles which does not require re-heating the polyethylene terephthalate (PET) pellets after they are cut and crystallized in the under water cutting (UWC) section. In the existing solid state polycondensation (SSP) technologies where an UWC is used, high crystallinity of the PET pellets can occur, by cooling and re-heating the PET pellets, which results in reduced removal efficiency of by-products, such as acetaldehyde (AA) and furthermore also a reduction of the reaction rates of molecular weight increasing reactions.

  • Patent number: 10933582
    Abstract: Devices, systems, and methods are directed to the use of vapor phase change in binder jetting processes for forming three-dimensional objects. In general, a vapor of a first fluid may be directed to a layer of a powder spread across a build volume. The vapor may condense to reduce mobility of the particles of the powder of the layer. For example, the condensing vapor may reduce the likelihood of particle ejection from the layer and, thus, may reduce the likelihood of clogging or otherwise degrading a printhead used to jet a second fluid (e.g., a binder) to the layer. Further, or instead, the condensing vapor may increase the density of the powder in the layer which, when repeated over a plurality of layers forming a three-dimensional object, may reduce the likelihood of slumping of the part during sintering.
