Abstract

UN SISTEMA DE SINTERIZACION DE LASER A TEMPERATURA CONTROLADA COMPRENDE UN HAZ LASER (12) QUE ESTA ENFOCADO SOBRE UN LECHO DE SINTERIZACION (38) POR UN ESPEJO DE FOCALIZACION (26) Y UN JUEGO DE ESPEJOS DE EXPLORACION (32, 34). LA RADIACION TERMICA (14) EMITIDA DESDE EL LECHO DE SINTERIZACION (38) FORMA UNA IMAGEN EN LOS ESPEJOS DE EXPLORACION Y EN EL HENDEDOR DE HAZ (110) QUE REFLEJA TAL RADIACION PERO PASA LA LONGITUD DE ONDA DEL HAZ LASER (12). LA RADIACION (118) ESTA ENFOCADA SOBRE UN DETECTOR OPTICO (126) QUE EMITE UNA SEÑAL SOBRE UNA LINEA ((128) A UN CIRCUITO DE CONTROL DE POTENCIA (104). EL CIRCUITO DE CONTROL DE POTENCIA (104) CONTROLA UN MODULADOR (100) QUE MODULA LA POTENCIA DEL HAZ LASER (112) DE MANERA QUE MANTENGA LA EMISION DE RADIACION TERMICA (114) (Y ASI LA TEMPERATURA EN LA LOCALIZACION DE SINTERIZACION) A UN NIVEL SUSTANCIALMENTE CONSTANTE.
