Open the CIPO recordAbstract From the Canadian patent
A three-dimensional porous structure is produced. A first layer of metal powder is deposited and scanned with a beam to form a portion of a plurality of predetermined unit cells. At least one additional layer of metal powder is deposited onto a previous layer and a beam is repeatedly scanned for at least one of the additional layers in order to continue forming the portions of predetermined unit cells. Porosity of the porous structure is varied by forming unit cells in different layers having different shapes or struts of different dimensions or by randomly perturbing vertices of unit cells to randomize their geometries.
