SCANNING STRATEGY FOR VOLUME SUPPORT IN ADDITIVE MANUFACTURING

摘要

A method of additive manufacturing of the component is presented. The method comprises, a), providing a component (10) geometry with a hole (11) and, b), selectively irradiating a powder bed (P) with an energy beam according to said geometry in a layerwise manner, wherein in layers (L) of the component (10) including the hole (11), the respective regions which define the hole (11) are irradiated with the energy beam such that a supporting structure (12) is generated in the hole (11) having a lower rigidity than a structure of the component (10). Furthermore, a use of the supporting structure for counteracting stress or distortion during the additive buildup and a computer program product as well as an apparatus corresponding to said method are presented.
