EQUIPMENT FOR USE IN PUBLISHED LASER DIRECTIVES

摘要

Improved gas flow systems and procedures for use with powder-based laser-radditive production chambers are described. The revealed gas flow configurations and associated chamber designs improve the removal of laser melting emissions. After various configurations, the removal rate of contamination with generated sprinklers is improved by using system designs that reduce the gas flow output to the substrate that increases the gas flow channel length,a uniform gas flow is made possible using multi-channel pumps and/or one or more additional gas inlets are introduced into the chamber design.
