Claim 18:
19. An interbody implant device for use between bony structures and/or cartilage; said interbody implant includes a frame structure and a porous structure positioned at least partially within said frame structure; said interbody implant device includes a top surface, a bottom surface, a front wall, a rear wall, a first side wall, and a second side wall; said frame structure includes a rear plate, an outer top rim, an outer bottom rim, an inner top rim, and an inner bottom rim; said rear plate forms at least a portion of said rear wall; said outer top rim forms an outer peripheral edge of said top surface; said outer bottom rim forms an outer peripheral edge of said bottom surface; said outer top and bottom rims are spaced from one another; said inner top rim and said inner bottom rim are spaced from one another; said outer top rim is spaced from said inner top rim; said inner top rim forms at least a portion of said top surface of said interbody implant device; said outer bottom rim is spaced from said inner bottom rim; said inner bottom rim forms at least a portion of said bottom surface of said interbody implant device; said frame structure includes a central opening; said inner top rim defines an upper perimeter of said central opening; said inner bottom rim defines a lower perimeter of said central opening; a bottom surface of said inner top rim is partially or fully absent said porous structure to form an upper undercut in said central opening; a top surface of said inner bottom rim is partially or fully absent said porous structure to form a lower undercut in said central opening; said porous structure at least partially formed of a series of overlapping layers in 3D space resulting in a randomized pattern of voids and webs wherein a) said overlapping layers have an overlap of 5-100%, b) said voids in said porous structure have a size of 0.001-0.5 in., c) a thickness of said webs is 0.0005-0.1 in., or any combination of a), b) and c).
