1. A method of forming a cutting element, comprising:
forming an assembly comprising a supporting substrate, a hard material powder over the supporting substrate, and an acid-dissolvable structure embedded within the supporting substrate and the hard material powder;
defining a geometry of a fluid pathway with the acid-dissolvable structure;
subjecting the supporting substrate, the hard material powder, and the acid-dissolvable structure to elevated temperatures and elevated pressures to inter-bond discrete hard material particles of the hard material powder and form a cutting table attached to the supporting substrate; and
removing the acid-dissolvable structure from the cutting table and the supporting substrate forming the fluid pathway.
