Abstract
A method of forming an orthopaedic implant having a porous surface layer thereon. A mask includes a cut-out configured to receive a portion of the implant therein. The implant is placed within the cut-out and thereby masked. A water soluble binder solution is sprayed onto at least a part of the unmasked portion of the implant using a sprayer, thereby forming a binder layer on the implant. The binder solution includes water, ethanol, gelatin, glycerin, and a colorant. A porous layer including a plurality of metallic particles is contacted with the binder layer. The porous layer is bonded with the surface of the implant with a sintering process.
