摘要： A print engine of an additive manufacturing system includes a print station configured to hold a removable cartridge containing powder. A laser engine is positioned to direct a one or two dimensional patterned laser beam into the removable cartridge. In some embodiments powder is produced at least in part with a magnetohydrodynamic system.
