Abstract
The invention relates to a device (100) for an additive manufacture. The device (100) comprises a laser device (110) for machining material using a laser beam (112), said laser device (110) being designed to deflect the laser beam (112) onto a machining region of a workpiece (10); at least one supply device (130) for a supply material, said supply device being designed to supply the supply material to the machining region; and an interferometer (140) which is designed to measure a distance to the workpiece (10) by means of an optical measuring beam (142).
Claims12
An apparatus for additive manufacturing, the apparatus comprising:
- a laser apparatus configured for material processing by a laser beam, wherein the laser apparatus is configured to steer the laser beam onto a processing region of a workpiece;
- at least one supply apparatus for a supply material, the at least one supply apparatus being configured to supply the supply material to the processing region;
- and
- an interferometer unit comprising an interferometer, the interferometer being configured to measure a distance to a surface of the workpiece using at least one optical measurement beam,
- wherein the interferometer is configured to move the at least one optical measurement beam in linear and rotary movements with respect to the laser beam.
