Curing is the final hardening stage for a resin print after it leaves the printer. In this step, the printed part is exposed to UV light, sometimes with heat, so the photopolymer resin finishes cross-linking and reaches its intended strength, stiffness, and surface stability. Before curing, a print may look complete but still be soft, fragile, or slightly tacky.
In cyber security and hardware work, curing matters because many attackers and defenders rely on resin prints for enclosures, jigs, mounts, and prototype parts. Under-cured parts can crack, deform, or fail when installed in a device, while over-curing can make them brittle or change dimensions. A careful workflow uses washing, controlled UV exposure, and inspection to produce repeatable parts. That consistency is important when a printed component must fit a sensor, protect a board, or support a secure test setup.
