Claim 0:
1. A method, comprising:
laser ablating selected regions of a cemented carbide substrate, thereby forming the cemented carbide substrate into a selected shape;
after laser ablating selected regions of the cemented carbide substrate:
enclosing a plurality of diamond particles and the cemented carbide substrate in a pressure transmitting medium to form a cell assembly; and
subjecting the cell assembly to a temperature of at least about 1000° C. and a pressure in the pressure transmitting medium of at least about 4 GPa to infiltrate the plurality of diamond particles with a portion of a metal-solvent catalyst of the cemented carbide substrate and catalyze formation of a polycrystalline diamond table that is bonded to the cemented carbide substrate.
