ADDITIVE MANUFACTURING APPARATUS AND METHODS

A method of building a workpiece in an additive manufacturing process, in which the workpiece is built through layer-by-layer solidification of material. The method includes, for a bridging layer in which an area to be solidified bridges material solidified as separate islands in an immediately prec...

Zusammenfassung:	A method of building a workpiece in an additive manufacturing process, in which the workpiece is built through layer-by-layer solidification of material. The method includes, for a bridging layer in which an area to be solidified bridges material solidified as separate islands in an immediately preceding layer, first, solidifying separated portions of the area, each separated portion connected with a different one of the islands of the preceding layer, and then solidifying material between the separated portions to join the separated portions together.
