Abstract

CáMARA DE PROCESSO E MéTODO PARA UM PROCESSAMENTO DE UM MATERIAL POR MEIO DE UM FEIXE ORIENTADO DE RADIAçãO ELETROMAGNéTICA, E, DISPOSITIVO DE SINTERIZAçãO A LASER Uma câmara de processo para um processamento de um material por meio de um feixe orientado de radiação eletromagnética é provida, que compreende um elemento óptico (9) para acoplar o feixe (7) no interior de uma câmara de processo (10), em que o elemento óptico tem uma superfície (9a) voltada em uma câmara de processo, uma seção de parede (12) circundando o elemento óptico (9), uma primeira entrada (16) para um gás que é disposta em um lado do elemento óptico (9) e configurada de modo que um primeiro fluxo de gás de escapamento (18) incide substancialmente tangencialmente sobre a superfície (9a) do elemento óptico (9), uma segunda entrada (23) para um gás, que é configurada e disposta de modo que um segundo fluxo de gás de escapamento (25) flui a uma distância com respeito à superfície (9a) em substancialmente a mesma direção que o primeiro fluxo de gás (18).
