Embodiment Construction

[0029] figure 1 A schematic diagram of a system 1 according to one embodiment is shown. exist figure 1 Only those partial parts of the system 1 that are relevant for explaining the principles described below are shown in the sectional view.

[0030] The system 1 is used for the additive production of layers of a build material 3 curable by means of a laser beam 5 , that is to say for example metal powder, by selectively irradiating and thus selectively curing layer by layer in succession. A three-dimensional object 2 , that is to say in particular a technical component or a group of technical components. The selective curing of the respective layer of construction material to be cured is carried out on the basis of object-related construction data. The corresponding construction data describe the geometrical or geometrical structural design of the object 2 to be additively produced in each case and may contain, for example, “scribed” CAD data of the object 2 to be produced....

Abstract

An apparatus (1) for additive manufacturing of three-dimensional objects (2) by successive, selective layer-by-layer exposure and thus successive, selective layer-by-layer solidification of construction material layers of construction material (3) that can be solidified by means of an energy beam, comprising a filter device (7) provided for filtering process gas (9) arising in the course of performing additive construction processes in a process chamber (8) of the apparatus (1), especially containing impurities arising in relation to the process, wherein the filter device (7) comprises severalfilter modules (14) with a filter module housing (15) each, wherein every filter module housing (15) comprises a filter body receiving room (16) configured with a defined geometry provided for receiving a defined number of filter bodies (18) configured with a defined geometry, wherein every filter module (14) comprises connection interfaces (19, 20) on the filter module via which it is or can beconnected, if required, to defined connection areas (21, 22) of a pipe structure (12) of the apparatus that is or can be flown through by the process gas (9).

Description

technical field [0001] The invention relates to a system for the additive production of three-dimensional objects by sequentially selectively irradiating and thus successively layer-by-layer selective curing of layers of building material consisting of a building material curable by means of an energy beam, including filtering A device, which is provided for filtering the process gas which is produced in the process chamber of the system during the implementation of the additive manufacturing process, in particular contains process-dependent impurities. Background technique [0002] Corresponding systems for the additive production of three-dimensional objects, for example in the form of systems for carrying out selective laser sintering or selective laser melting methods, are basically known. Corresponding systems usually include a filter device, which is provided for filtering impurities that are generated in the process chamber of the system during the implementation of t...
