Abstract

a presente invenção refere-se a um dispositivo (10, 100, 150, 200, 250, 300), especialmente para produção aditiva camada-por-camada de um componente tridimensional complexo (12), com um dispositivo de medição (30, 202, 252, 302) para monitoramento contínuo de parâmetros de qualidade, especialmente da temperatura e/ou de uma composição química de uma atmosfera de gás de proteção (24), durante a produção do componente (12), sendo que o dispositivo de medição (30, 202, 252, 302) e um leito (14) com um pó de material (16) estão circundados, pelo menos em regiões, por uma célula de tratamento (22) enchida com uma atmosfera de gás de proteção (24), e um pó de material (16) de uma camada mais superior (18) pode ser aberto por fusão localmente, por meio de pelo menos um laser (32, 204, 254, 304) em uma zona de fusão (42). de acordo com a invenção, o dispositivo de medição (30, 202, 252, 302) apresenta o dito pelo menos um laser (32, 204, 254, 314) e pelo menos um sensor ótico (34, 206, 218, 256, 306, 308) para detecção prioritária dos parâmetros de qualidade na região da zona de fusão (42), especialmente por meio de uma espectroscopia raman. em consequência disso, possíveis erros de construção no componente (12) podem ser reconhecidos, avaliados e eventualmente corrigidos com segurança, de modo a poupar recursos.
