Abstract
método e dispositivo de controle da densidade de energia de um feixe de laser a presente invenção refere-se ao campo de peças de fabricação através de fusão seletiva a laser (slm), isto é, uma técnica para fabricação de aditivo capaz de produzir peças de metal por meio de lasers de alta potência que realizam a fusão, localmente e de forma gradual, isto é, em uma forma seletiva, de um pó de metal em uma atmosfera controlada. o método de controle (s) da densidade de energia de um feixe de laser (3), a partir de pelo menos dois parâmetros do feixe de laser (3), compreende as etapas de aplicar regularmente o feixe de laser (3) em um suporte de referência (7) e medir (s4), a cada aplicação, a intensidade de luz obtida nesse suporte de referência, identificar (s6, s7, s8) uma variação na intensidade de luz no suporte de referência (7) entre pelo menos duas medições, e quando a variação na intensidade de luz for maior do que um determinado limiar, determinar o(s) parâmetro(s) instável(is) da densidade de energia do feixe de laser (3) (s8).
