Abstract
An apparatus () for producing three-dimensional work pieces comprises a carrier () adapted to receive a raw material powder (). The apparatus () further comprises an irradiation unit () for selectively irradiating electromagnetic or particle radiation onto the raw material powder () applied onto the carrier () in order to produce a work piece made of said raw material powder () by a generative layer construction method. The irradiation unit () comprises a radiation source () and a plurality of optical elements. A detection device () of the apparatus () is arranged so as to be capable of detecting an operational parameter of a radiation beam () emitted by the radiation source () and having passed at least one optical element of the irradiation unit ().
