3D Systems SLA 825 Dual: Revolutionizing Large-Scale Stereolithography 3D Printing

In 1987, 3D Systems pioneered the additive manufacturing industry with the introduction of the world’s first commercial stereolithography (SLA) 3D printer. This groundbreaking innovation laid the foundation for one of the most accurate and widely adopted 3D printing technologies available today. Nearly four decades later, 3D Systems continues to lead the way in shaping the field it originally established. Their latest advancement, the SLA 825 Dual, is meticulously engineered to elevate large-scale SLA production to unprecedented levels. This powerful system seamlessly integrates speed, scale, and accuracy, providing manufacturers with a comprehensive solution for demanding applications.

The SLA 825 Dual boasts an impressive build volume of 830 x 830 x 550 mm, making it an ideal choice for manufacturers requiring high throughput without sacrificing precision. This advanced 3D printer empowers users to create intricate and complex parts with remarkably fast turnaround times and significantly reduced labor costs. Explore the key features of the SLA 825 Dual detailed below, and be sure to visit 3D Systems at Hall 11.1, D11 at Formnext 2025 to witness its capabilities firsthand.

Unleashing Precision and Productivity for Demanding Industries

The SLA 825 Dual is specifically designed for industries where accuracy and surface finish are paramount. Foundries, aerospace and defense organizations, automotive and motorsport companies, and service bureaus can all significantly benefit from the system’s exceptional combination of capacity and consistent performance. This printer addresses the critical need for reliable, high-quality large-scale 3D printing in these demanding sectors.

The versatile applications of the SLA 825 Dual span a wide range of industries. Typical use cases include the creation of full-scale wind tunnel models for aerodynamic testing, the production of investment casting patterns for metal part manufacturing, aesthetic design verification to evaluate product appearance, and the creation of functional prototypes to validate designs. Furthermore, the SLA 825 Dual supports low-volume production of general manufacturing and consumer goods, as well as the creation of mandrel tooling.

To achieve these outstanding results, the SLA 825 Dual leverages dual 4W lasers powered by 3D Systems’ proprietary HyperScan Technology. This advanced technology allows the printer to achieve a layer resolution of 100 μm and a minimum feature size of just 0.127 mm (0.005 in) in the XY plane. These capabilities enable manufacturers to achieve the intricate details and exceptional surface quality that SLA 3D printing is renowned for, even at significantly larger scales.

Unmatched Material Compatibility and Comprehensive Post-Processing Solutions

The SLA 825 Dual exhibits broad material compatibility, supporting the Accura AMX family of production-grade resins. These resins are available in a diverse range of colors and mechanical properties, allowing users to select the optimal material for their specific application requirements. In addition to the Accura AMX resins, the SLA 825 Dual also accommodates specialized materials such as QuickCast® resins designed for investment casting, wind tunnel F1 formulations tailored for aerodynamic testing, and general-purpose photopolymers for a variety of applications. This extensive material selection empowers users to customize their 3D printing process to perfectly match the unique demands of their projects.

To ensure that printed parts achieve their full mechanical and dimensional potential, 3D Systems offers a suite of dedicated post-processing solutions designed to complement the SLA 825 Dual. The PostCure 1050 is specifically optimized for curing large parts produced by the SLA 825 Dual, delivering uniform and efficient curing even for the largest build sizes. For smaller or mixed workflows, the Cure 400 provides a compact and versatile alternative, offering excellent curing performance in a smaller footprint. These post-processing solutions are critical for maximizing the performance and longevity of 3D printed parts.

Streamlining Workflow with 3D Sprint® Software

Beyond its impressive hardware capabilities, the SLA 825 Dual seamlessly integrates with 3D Systems’ 3D Sprint® software, a single, comprehensive platform for file preparation, optimization, and printer management. This integration simplifies the entire 3D printing workflow, from design to final part production.

With 3D Sprint®, users can seamlessly transition from CAD design to 3D printing without the need to switch between multiple software programs. The software’s powerful tools for CAD optimization, data management, and printer monitoring help minimize downtime and streamline production. Its intuitive interface is designed to maximize productivity, ensuring that operators can focus on achieving optimal output rather than troubleshooting technical issues. 3D Sprint is a critical component of the SLA 825 Dual ecosystem, enabling users to unlock the full potential of the 3D printer.

The SLA 825 Dual represents 3D Systems’ continued commitment to innovation in SLA technology, combining unparalleled scale, precision, and reliability to meet the ever-evolving needs of advanced manufacturing. For industries constantly pushing the boundaries of design and production, the SLA 825 Dual signals the arrival of the next generation of stereolithography 3D printing. Its unique capabilities and comprehensive ecosystem make it an ideal choice for companies seeking to leverage the benefits of large-scale, high-precision additive manufacturing.
