What is Sand 3D Printing?

Sand 3D printing uses binder jetting technology to create complex molds and cores directly from CAD data. Unlike traditional tooling, it eliminates patterns, reduces lead time, and allows intricate internal geometries. These printed molds are then used for metal casting in aluminum, steel, iron, or other alloys.

Complex geometries without tooling
Cost-effective for low to medium volume production
Fast lead times (days instead of weeks)
Compatible with a wide range of metals
Scalable for prototyping and mass production
