Patent number: 10525688Abstract: The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.Type: GrantFiled: March 27, 2015Date of Patent: January 7, 2020Assignees: Howmedica Osteonics Corp., The University Of LiverpoolInventors: William O'Neill, Christopher J.

Publication number: 20160098495Abstract: Aspects of the present disclosure relate generally to preparing models of three-dimensional structures. In particular, a model of a three-dimensional structure constructed of porous geometries is prepared. A component file including a porous CAD volume having a boundary is prepared. A space including the porous CAD volume is populated with unit cells. The unit cells are populated with porous geometries having a plurality of struts having nodes on each end. The space is populated with at least one elongated fixation element extending beyond the boundary to produce an interlocking feature enabling assembly or engagement with a mating structure.Type: ApplicationFiled: October 7, 2015Publication date: April 7, 2016Inventors: Nicholas Nai Guang Dong, Matthew P. Poggie, Robert W. Klein, Eric Jones, Christopher J. Sutcliffe, Joe Robinson, Dan Jones, Lewis Mullen, Robin Stamp
