POROUS STRUCTURES PRODUCED BY ADDITIVE LAYER MANUFACTURING

A three-dimensional structure is disclosed that is formed when layers of a material are deposited onto a substrate and scanned with a high energy beam to at least partially melt each layer of the material. Upon scanning the layers at predetermined locations a first segment overlapping a second segme...

Zusammenfassung:	A three-dimensional structure is disclosed that is formed when layers of a material are deposited onto a substrate and scanned with a high energy beam to at least partially melt each layer of the material. Upon scanning the layers at predetermined locations a first segment overlapping a second segment and underlapping a third segment is formed. A method of facilitating bone ingrowth is also disclosed.
