Overly Complex Shell Geometry
Intricate curves or thin-wall sections that look striking in a 3D rendering can be difficult or costly to mold reliably at scale — a manufacturability review before finalizing industrial design catches this early.
Underestimating Tolerance Stack-Up
Individually reasonable tolerances on multiple mating parts can compound into a poor fit when assembled together — a common surprise for first-time buyers designing without manufacturing engineering input from the start.
