Abstract
A device and a method for layerwise, generative production of three-dimensional objects are provided. Multiple objects are produced in parallel in distinct process chambers (11, 12, 13, 14) by means of successive application of layers of a building material and subsequent solidifying of a layer and interconnecting of the layer with the previously applied layer, respectively, by means of radiation. The radiation is supplied to a part of the process chambers by a radiation source which is arranged outside of the process chambers, while an application of a layer takes place in another part of the process chambers.
Claims12
Device for layerwise generative production of three-dimensional objects by acting of electromagnetic or particle radiation at respective positions corresponding to the cross-section of the object in the respective layer comprising:
- at least two building regions which are separated from each other for objects to be produced;
- a radiation source for emitting the electromagnetic or particle radiation toward the building regions, characterized by a switch device for switching a pathway of the radiation from the radiation source towards the building regions such that one building region is irradiated at a time, wherein the switch device comprises a switchable optical element or a beam switch, and
- a control device which controls the switch device to apply the radiation source for concurrent production of an object in each building region, such that during a process step in one building region which runs without participation of the radiation source, a process step with participation of the radiation source runs in another building region.
