S-Max +TM Industrial Production 3D Printer

The Solution for Large and Robust but Delicate Sand Cores 

The S-Max+™ prints very large, complex sand cores and mold packages for metal casting directly from CAD data, eliminating the need for a physical pattern or tooling. Designed to be used in conjunction with an industrial microwave for curing, this printer supports cores used in high-temperature casting or when intricate details are required. Changes in design can be immediately implemented. The ExOne® 3D printing process economically provides complex molds and cores for industries such as automotive, aerospace, heavy equipment and energy.

Choosing Phenolic binder enables high temperature casting, high flexural strength and extremely thin walls and channels. Silicate binder offers low gas emissions and is an economical, non-hazardous choice for detailed cores. Both binders utilize microwave technology for post-print curing.
