3D Sand Printing

Print Sand Casting Molds & Cores Directly from CAD 

Hoosier Pattern's ExOne S-Max™ system selectively dispenses foundry-grade resin into thin layers of specially engineered sand. With an on-demand sand management system, a printhead offering precise dosing of the binding agent, and capabilities for complex internal details. The process produces accurate, uniform cores and molds rapidly, significantly reducing lead time. if you can design it, we can build it. 

Our Design Engineers Can Help Bring Your Designs to Life

Have a specific need, but don't have the resources to design it? Hoosier Pattern has an experienced team of CAD designers who have a passion for precise, efficient design. With experience ranging from CNC patterns to foundry gating, our CAD designs, as realized by the ExOne S-Max™ system, give you the complexity you need, with tolerances your product requires. 

When determining the cost for a printed sand core/mold, take the L x W x H of the bounding box of the piece to be printed and multiply this by $0.15 (for most product)

Most lead times are 10 business days but can be expedited for an additional fee. 

If we do not have to clean the core and can print the part in a printed box and you can extract the part, cost is $0.13/cubic inch with a normal lead time of 1 week. HPI does have a minimum printing charge of$450 and packaging material and shipping is an additional charge.
