  • Publication number: 20240058737
    Abstract: The invention concerns a method for the removal of a part (41, 55) of a particle collecting device (40, 41, 42, 55), which part is loaded with at least highly flammable particles (51). The part (41, 55) is removed from a process gas cleaning device (100) of an additive manufacturing device (1) by means of the following steps. An inert gas (50, 250) which substantially encloses the particles (51) is provided. The part (41, 55) of the particle collecting device (40, 41, 42, 55), is removed from the process gas cleaning device (100), wherein the particles (51) remain enclosed in the inert gas (50, 250).

  • Publication number: 20230264263
    Abstract: Disclosed is a filter system for an additive manufacturing device for purifying a process gas of the additive manufacturing device wherein, in order to purify a volume of process gas during operation, the filter system has at least one permanent filter. The permanent filter is configured so as to be thermally stable in a manner such that during operation, the permanent filter is stable at a temperature of more than 110° C. Further disclosed is an additive manufacturing device as well as an additive manufacturing process.

  • Patent number: 11667082
    Abstract: An apparatus for manufacturing a three-dimensional object by a layer-by-layer solidification of building material at the points corresponding to the cross-section of the object to be manufactured in a respective layer. The apparatus includes a process chamber in which the object is to be built up layer by layer by selectively solidifying layers of a building material in a build area, a gas supply device, and a recirculating air filter device, wherein the apparatus comprises a pressure stabilization device configured to keep the pressure in the process chamber substantially constant.

  • Publication number: 20220118513
    Abstract: The present invention relates to a method for the post-treatment of particles (51) carried along in a process gas (50) of a device (1) for the generative manufacturing of three-dimensional objects, wherein the particles (51) are conducted to a filter chamber (40). An oxidant (60) is added to the particles (50) and that an oxidation reaction of the particles (50) with the oxidant (60) is initiated.
