Problems solved by technology

[0003] It is further known from the prior art that the amount of energy consumed in the construction material is critical to the quality of the process and the quality of the object, since if the energy consumed in the construction material is insufficient or exceeds a defined interval or value, it may result in deviation or negative effect on the object to be built

Embodiment Construction

[0024] The only graph ( figure 1 ) shows a device 1 for the additive production of a three-dimensional object 2 by sequentially selectively irradiating and curing layers of a build material 3 curable by means of an energy beam 4 . The energy beam 4 is generated by a beam generating unit 5, eg a laser beam source.

[0025] In this exemplary embodiment, the energy beam 4 is focused on the build plane 6 and irradiates the build material 3 in the curing zone 7, wherein splash particles 8 are produced, for example by at least partially evaporating the build material 3 in the curing zone 7, 9 and 10. According to the situation described, the energy dissipated in the build plane 6 irradiated with the energy beam 4 , in particular in the build material 3 located in the curing zone 7 of the build plane 6 , leads to partial evaporation of the build material 3 . The corresponding partially evaporated build material 3 produces splash particles 8 - 10 which move out of the solidification...

Abstract

The invention relates to a device (1) for the additive production of three-dimensional objects (2) by sequentially selectively irradiating and curing layers of a building material (3) curable by means of an energy beam (4) , wherein the detection device (13) is configured to detect splash particles (8‑10) generated by at least partially evaporating the building material (3) in the curing region (7) where the energy beam (4) In (7), the construction material (3) is irradiated.

Description

technical field [0001] The invention relates to a device for the additive production of three-dimensional objects by selectively irradiating and curing layers of a construction material curable by means of energy beams sequentially layer by layer. Background technique [0002] Apparatus in which an energy beam is provided to selectively irradiate and thereby cure a layer of build material in a build plane are well known in the art. Objects are additively manufactured by sequentially illuminating layers of build material. To cure the building material, energy is dissipated in the curing area by means of energy beams. Depending on various parameters, such as energy beam power or energy beam intensity, the (powdered) build material in the solidification zone can be sintered or melted and thus solidified. [0003] It is further known from the prior art that the amount of energy consumed in the construction material is critical to the quality of the process and the quality of t...
