Device for acting on a work area with laser radiation, in particular 3D printing device

摘要

3D printing apparatus for the production of a spatially extended product, comprising at least one laser light source from which a laser radiation can emerge, a working area, which is or can be supplied with laser radiation to be acted upon starting material for the 3D printing, the working area in such the 3D printing device is arranged so that the laser radiation impinges on the working area, scanning means which allow a relative movement of the working area relative to the laser radiation and / or the laser radiation relative to the working area, and optical means for beam shaping the laser radiation such that in operation At least one linear intensity distribution (1) is produced in the working area of the 3D printing device, wherein the scanning means and / or the optical means are designed so that the relative movement between the at least one linear intensity distribution (1) and the working area is in line length direction ung (2) takes place.
