APPARATUSES AND METHODS FOR ADDITIVELY MANUFACTURING AN OBJECT FROM A POWDER MATERIAL

Abstract:

A method (1000) of additively manufacturing an object (200) from a powder material (202) comprises discharging the powder material (202) from a powder-deposition opening (126) in a hollow body (122) of a powder-supply arm (108) while rotating the powder-supply arm (108) and an energy-supply arm (112) about a vertical axis A1. Method (1000) also comprises, while rotating the powder-supply arm (108) and the energy-supply arm (112) about the vertical axis A1, distributing the powder material (202) within a powder-bed volume (204) using a powder-distribution blade (128) that is coupled to the hollow body (122) and extends along the powder-deposition opening (126). The method (1000) further comprises, while rotating the powder-supply arm (108) and the energy-supply arm (112) about vertical axis A1, consolidating at least a portion of the powder material (202) in the powder-bed volume (204) using the energy emitters (114), coupled to the energy-supply arm (112).
