A thermoset resin for forming parts to be metal plated includes a vat photopolymerization (VPP) thermoset resin and an etchable phase disposed in the VPP thermoset resin. The etchable phase is etched from a surface of a part formed from the VPP thermoset resin such that a plurality of micro-mechanical locking sites is formed on the surface of the part. The etchable phase is at least one of organic particles, organic resins, inorganic particles, and copolymers of the VPP thermoset resin. For example, the etchable phase can be a polybutadiene phase and/or a mineral such as calcium carbonate.
