Our Process
3D sand molding uses binder-jet printing to produce complete sand molds and cores directly from your CAD file — no physical pattern required. The printed sand mold is assembled at our foundry and poured using the same alloys, furnaces, and heat certifications as our conventional production work.
The primary applications are prototype castings, first articles, short production runs, and complex internal geometry that is difficult or impossible to core conventionally. Send us your CAD model and alloy specification and our engineers will design the risering and gating system and coordinate the mold print.

Lead Time Advantage
Eliminate pattern fabrication lead time — prototype castings poured in days from your approved CAD model
Advantages
3D printed sand molds are produced directly from CAD files — no wood or resin pattern needed. Eliminate pattern lead time and tooling cost entirely for prototype and short-run work.
Binder-jet printing can produce mold cores that are impossible to make conventionally — intricate oil passages, undercuts, and compound internal shapes with no assembly required.
First casting in days rather than weeks. 3D sand printing removes the longest lead time item — pattern fabrication — from the critical path.
3D-printed sand molds are compatible with all alloys Ironbound pours — bronze, aluminum, nickel alloys, Monel, and stainless steel.
