ExOne Unveils S-Print Pro Sand Binder Jetting System for Smaller Foundries

ExOne has launched the S-Print Pro, a new sand binder jetting (BJT) system specifically engineered for smaller foundries and pattern shops. This development aims to address the historical pricing barriers that have kept these businesses from adopting industrial additive manufacturing (AM) technologies. The machine occupies less than 12 square meters of floor space and is positioned as an accessible entry point for production-grade sand 3D printing.

The S-Print Pro is a result of the combined engineering expertise and application knowledge gained from the merger between ExOne and voxeljet. According to CEO Eric Bader, the system fulfills a long-standing request from foundries for an industrial sand printing solution that is affordable to acquire, install, and operate. This launch signifies ExOne's commitment to increasing the accessibility of industrial binder jetting globally.

The system features a substantial build volume of 1,200 × 750 × 500 mm and supports a standard layer thickness of 0.28 mm, with a variable range from 0.10 to 1.00 mm. ExOne reports that the S-Print Pro can complete a full job box within a single shift. It is compatible with furan binder and silica sand, with optional materials including CeraBeads and silicon carbide.

Key innovations in the S-Print Pro include the CoreBoost printhead generation, offering 400 dpi resolution and available in two configurations optimized for either print performance or reduced operating costs. An optional StepX feature provides in-situ surface smoothing to mitigate the stair-stepping effect common in layer-by-layer printing. The user-replaceable printhead modules and a two-canister system are designed to minimize downtime.

ExOne is targeting the S-Print Pro towards foundries with fewer than 100 employees, a segment considered underserved by current industrial BJT systems. Aldo Randazzo, Director of Application Management and ODP Administration at ExOne, highlighted that most of the world's foundries are small operations and that industrial binder jetting has not historically been scaled or priced for their needs. Intended applications include low-volume casting, contract manufacturing, spare-part production, custom components, and specialized supply chain needs.

Deliveries of the S-Print Pro are slated to commence in the second quarter of 2026, with initial units allocated to beta partners and early reservation holders. ExOne is accepting reservations via email and through regional representatives, offering customized total-cost-of-ownership assessments.
