What files and specs do manufacturers need for custom brass jewelry?
Supply neutral 3D solids (STEP/IGES), layered 2D vectors (DXF/PDF/AI), high-res textures, and a clear spec sheet: units, scale, tolerances, minimum wall thickness, finish codes and plating thickness in microns, BOM, and assembly notes. Proper files cut tooling cycles, scrap and cost.
Quick Summary
Provide neutral 3D solids (STEP/IGES) plus native CAD and high-resolution STL/3MF for prototyping; 2D DXF/PDF/AI with text converted to outlines for profiles and engravings; a detailed spec sheet with units, tolerances, minimum wall thickness by process, finish codes and plating thickness (microns), BOM and assembly notes. Clean, annotated files reduce tooling cycles, rework and unexpected costs.
