How to Find a Chinese Supplier to Mass-Produce a Custom 3D-Printed Product

The first mistake sellers make when they want to mass-produce a custom 3D-printed product in China is searching for a "3D printing supplier." Most Chinese factories that serve high-volume orders are not running FDM or resin printers at scale. They are running injection-molding lines, CNC machining cells, or silicone casting setups — and each of those transitions requires a different supplier type, a different tooling investment, and a different verification process.
