3D Sand Printing

Fast. Flexible. Tooling-Free.

At One Off Castings, we use industrial-grade 3D sand printing to produce high-precision molds and cores directly from your CAD file — no patterns, no hard tooling, and no delay. This digital-first approach enables rapid casting of complex geometries, making it ideal for prototypes, R&D parts, or low-volume production runs.

How 3D Sand Printing Works

1. Direct from CAD
   You provide your 3D model — we convert it into a print-ready mold or core using advanced binder jetting workflows.

2. Layer-by-Layer Mold Printing
   We print your mold using specialty foundry sand and high-performance binders, creating a precise, ready-to-pour cavity.

3. Pour and Cast
   Once printed, the mold is ready for molten metal. No pattern fabrication, no retooling — just cast and go.

Why Choose 3D Sand Printing?

• Tooling-Free Production
  Eliminate lead time and cost associated with patterns — ideal for prototypes, short runs, and urgent replacements.

• Design Freedom & Complexity
  Easily produce internal channels, undercuts, or organic geometries that traditional sand molds can’t support.

• Ultra-Fast Lead Times
  Go from CAD to cast part in a matter of days — perfect for compressed development cycles.

• Iterate with Ease
  Make real-time design changes — just update the CAD model and reprint the mold. No tooling revisions required.

Best Use Cases

• Functional metal prototypes

• Research & development components

• Emergency or replacement parts

• Intricate or highly customized geometries

• Short-run or low-volume castings
