    摘要: Die Erfindung betrifft eine Fertigungsanlage (10) zur Herstellung eines Bauteils mittels eines additiven Fertigungsverfahrens, bei dem ein formloser Werkstoff schichtweise aufgebracht und basierend auf einem digitalen Datenmodell selektiv ausgehärtet wird, wobei die Fertigungsanlage aufweist:
    - einen Werkstoffvorratsspeicher (11), in dem ein primärer Werkstoff (13) bereitgestellt wird,
    - einen Bauteilraum (12), in dem der primäre Werkstoff (13) schichtweise aufgebracht und selektiv ausgehärtet wird,
    - mindestens eine Rakel (14), die über dem Bauteilraum (12) bewegbar und zum schichtweisen Aufbringen des durch den Werkstoffvorratsspeicher (11) bereitgestellten primären Werkstoffes (13) während des Bewegens über dem Bauteilraum (12) ausgebildet ist, und
    - eine Energiequelle, die zum selektiven Aushärten des schichtweise aufgebrachten primären Werkstoffes (13) in dem Bauteilraum (12) ausgebildet ist.

    摘要: A powder is spread in two directions, that is, the advancement and retraction directions of a powder recoater. The powder recoater according to this invention includes a hopper that stores a powder, and a cylindrical powder supplier that has a side surface close to or in contact with the bottom surface of the hopper and includes a supply path for the powder. The powder recoater according to this invention further includes a pivoting unit that causes the powder supplier to pivot. In the powder recoater according to this invention, the center axis of the supply path is displaced from the center axis of the powder supplier in the radial direction of the powder supplier.

    摘要: A fabrication device includes a build surface for production of a 3-dimensional solid component, a material delivery system configured to deposit one or more build materials on the build surface, at least one of the one or more build materials being a photocurable material, a first imaging component having a first resolution, and a second imaging component having a second resolution different from the first resolution. In this configuration, the first imaging component and the second imaging component are operable individually and in combination together to selectively irradiate the photocurable material to at least partially solidify successive layers of the 3-dimensional solid component In one example, the lower resolution imaging component solidifies bulk interior regions and the higher resolution component solidifies detailed borders.

    摘要: A powder delivery device for providing raw material powder to a powder application device of a powder bed fusion apparatus is provided. The powder delivery device comprises a powder supply section configured to receive raw material powder, the powder supply section comprising an outlet for providing the raw material powder to the powder application device. The powder delivery device further comprises a first physical parameter determining unit arranged at a first location of the powder supply section and configured to determine a first physical parameter in the powder supply section, a control unit configured to determine whether the first physical parameter meets a first tolerance criterion, and a powder treatment unit, wherein the control section is configured to instruct the powder treatment unit to perform a powder treatment in case it determines that the first physical parameter does not meet the first tolerance criterion.
