3D Printed Sand Mold: Faster Prototyping for Aluminum Castings

From CAD to Casting in Days

Binder-jet 3D printing builds the mold layer by layer directly from a digital model. There is no pattern, no core box, and no waiting on machined tooling. Complex internal cooling channels, lightweight rib structures, and one-off geometries become feasible without extra cost.

Ideal for Low-Volume & Complex Parts

This approach suits prototyping, spare parts, and small-batch production of aluminum components — especially where geometry is too intricate for conventional molding. Bainuo pairs 3D printed sand molds with precision aluminum casting to deliver near-net-shape parts ready for machining.

Integrated Workflow

Because Bainuo also runs CNC machining, surface treatment and inspection in-house, a printed mold and its casting can move through one facility without hand-offs between vendors. That shortens the critical path and keeps tolerances consistent.
