Einseitige Zwei-Richtungszuführung zum Lasersintern

摘要

An apparatus and a method of using the apparatus to deliver metered quantities of powder to a target area (186) in a laser sintering process from a single sided bi-directional powder delivery system to ensure fresh powder is preheated prior to fusing the powder with a laser beam. Metered quantities of powder (184) are deposited for pre-heating adjacent the target area and then are spread by a mechanism (180) that traverses the target area.
