| 摘要 |
The invention relates to a method or an apparatus for the production of a three-dimensional object (9), wherein a photopolymerizable material (3) is compacted by means of simultaneous or nearly simultaneous radiation of a construction area on a construction plane (5) by means of electromagnetic radiation. The distance between a carrier platform, on which the object to be generated is constructed, and the construction plane is changed during at least one phase of radiation. According to the invention, it is possible to compact the three-dimensional object beyond a designated instantaneous through-hardening depth in a main direction of construction during a phase of radiation without interrupting the entry of electromagnetic energy during the phase of radiation. In addition, it is possible to control the instantaneous through-hardening depth of the photopolymerizable material during a construction stage. Variants of appropriate devices are also described. |
