Getting started with industrial sand 3D printing

24 Jun 2026

ExOne is targeting small and mid-sized foundries, pattern makers, and print service providers with its new compact sand 3D printer, the S-Print Pro.

Designed to operate in a footprint of less than 12 m², ExOne aims to combine “the accuracy and repeatability of the proven S-Max platform with low investment and operating costs.” The S-Print Pro was developed specifically for small-batch casting and contract manufacturing, spare parts production, the manufacture of custom components, and for use with special alloys—areas where smaller foundries often operate with limited automation and digitization.

Weighing 4,000 kg, the S-Print Pro offers several features to enhance productivity and ease of use, including the new CoreBoost printhead generation, available at 400 dpi resolution, and the new StepX in-situ surface smoothing option, which reduces the stair-stepping effect during printing. User-replaceable printhead modules simplify maintenance, while a service-friendly design—which allows for easy maintenance of the coater—along with a two-canister replacement system, keeps downtime to a minimum. An exclusively developed feature allows the same printhead to be used in different module configurations, offering the flexibility to either maximize print performance or reduce operating costs. Operation remains intuitive thanks to the proven user interface of the S-Max family.

“Most of the world’s foundries are small operations, many with fewer than 100 employees. They are the backbone of the manufacturing industry, yet industrial binder jetting has rarely been built for their scale or budget. We aim to close that gap with the new S-Print Pro,” explains Aldo Randazzo, Director of Application Management & ODP Administration at ExOne.

Despite its compact size (the build volume is 1,200 × 750 × 500 mm), the S-Print Pro is designed for productivity in single-shift operation. ExOne promises a complete job box in less than one shift. The system processes furan binder with silica sand, with the option of CeraBeads or silicon carbide. The layer thickness varies from 0.10 to 1.00 mm, with a standard thickness of 0.28 mm.

Deliveries of the S-Print Pro will begin in the second half of 2026—initially to selected beta partners.
