Abstract

A print engine of an additive manufacturing system includes a print station configured to hold a removable cartridge. A laser engine including a frame can be positioned to hold at least one removable field replaceable unit that includes at least some laser optics or patterning optics. An optical alignment system can be attached to at least one of the print station or the laser engine to align the field replaceable unit with respect to the removable cartridge.

ADDITIVE MANUFACTURING SYSTEM USING A PULSE MODULATED LASER FOR TWO-DIMENSIONAL PRINTING

      
Document Number 03124097
Status Pending
Filing Date 2019-12-19

  • Bayramian, Andrew J.
  • Demuth, James A.
  • Duanmu, Ning
  • Shen, Yiyu

Abstract

A method of additive manufacture is disclosed. The method may include providing a powder bed and directing a shaped laser beam pulse train consisting of one or more pulses and having a flux greater than 20 kW/cm2 at a defined two dimensional region of the powder bed. This minimizes adverse laser plasma effects during the process of melting and fusing powder within the defined two dimensional region.

IPC Classes  ?

  • B23K 25/00 - Slag welding, i.e. using a heated layer or mass of powder, slag, or the like in contact with the material to be joined
  • B23K 26/00 - Working by laser beam, e.g. welding, cutting or boring
  • B23K 26/34 - Laser welding for purposes other than joining
