ExOne launches compact S-Print Pro sand 3D printer

Key Takeaways

• The ExOne S-Print Pro is a compact industrial sand 3D printer designed for small and mid-sized foundries and pattern makers.
• It operates in under 12 m² of floor space and combines design elements from ExOne's S-Max platform with lower investment and operating requirements.
• The S-Print Pro offers part quality and repeatability comparable to the S-Max Pro in a smaller and lower-cost platform.
• It features the CoreBoost printhead generation at 400 dpi resolution and the StepX in-situ surface-smoothing option.
• The system is designed for productivity in single-shift operation and processes furan binder with silica sand, as well as CeraBeads or silicon carbide.

Introduction to the S-Print Pro

The ExOne S-Print Pro is a compact industrial sand 3D printer that brings binder jet sand printing to operations that need production capability in a smaller footprint. With a build volume of 1,200 × 750 × 500 mm (W × D × H) and a layer thickness of 0.10–1.00 mm, this printer is ideal for small to mid-sized part volumes.

Printing and Maintenance Features

The S-Print Pro includes the CoreBoost printhead generation at 400 dpi resolution, which provides high-quality prints with minimal layer lines. The StepX in-situ surface-smoothing option reduces stair-stepping during printing, resulting in smoother surface finishes. The system also features user-replaceable printhead modules, service-accessible construction, recoater maintenance features, and a two-canister change system to reduce downtime.
