Device and method for monitoring the state of a protective glass of a manufacturing system and manufacturing system for an additive manufacturing method

Abstract

The present invention relates to a manufacturing system 1 for manufacturing a workpiece 26 by exposing powder material and/or a workpiece element. The manufacturing system 1 comprises at least one light source 4 for irradiating the powder material 18 and/or workpiece element provided in a processing chamber 12; a light path 14 generated by the light source 4 which extends through a protective glass 10 into the processing chamber 12 of the manufacturing system 1, wherein the protective glass 10 is provided for protection against damage and/or contamination. At least one exposure device L1-L9 is provided for exposing an object plane 30 associated with the protective glass 10 of the manufacturing system 1. The exposure device L1-L9 encloses the protective glass 10 at least partially, preferably completely, and comprises a plurality of similar light-emitting diodes, LEDs for homogeneous illumination.
