Overlapping border and internal sections of object formed by different am melting beam sources in overlapping field region

A method for additive manufacturing an object is disclosed. The method includes, for a first portion of the object to be built in a first overlapping field region of a plurality of melting beams of a metal powder AM system, sequentially forming each layer of the first portion by: forming only a bord...

Zusammenfassung:	A method for additive manufacturing an object is disclosed. The method includes, for a first portion of the object to be built in a first overlapping field region of a plurality of melting beams of a metal powder AM system, sequentially forming each layer of the first portion by: forming only a border section of the first portion of the object using a first melting beam of the plurality of melting beams in the first overlapping field region; and forming an internal section of the first portion of the object within the border section using at least one second, different melting beam from the first melting beam in the first overlapping field region. An entirety of an internal edge of the border section of the first portion of the object is overlapped with an entirety of an external edge of the internal section of the first portion of the object.
