Title:
METHOD OF POWDER BED-BASED ADDITIVE MANUFACTURING OF AN INTRICATE STRUCTURE WITH PREDETERMINED POROSITY AND POROUS FUNCTIONAL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/263310
Kind Code:
A3
Abstract:
A method of powder bed-based additive manufacturing of an intricate structure (10) is specified, wherein the structure has a predetermined porosity, wherein a multitude of parallel irradiation vectors (v) is chosen for selective irradiation of a powder layer for the production of the structure (10), wherein melt pathways (V) generated by the parallel irradiation vectors (v) are free of overlaps and wherein the parallel irradiation vectors (v) also run parallel to the structure (10) to be formed thereby. Additionally specified are a computer program product (CP) and a corresponding porous functional structure (20).
