3D Systems’ New Monster Resin Printer Is 72x Larger Than Formlabs Form 4

Sure, comparing industrial to desktop tech is unfair, but it effectively puts the SLA 825’s monster footprint into perspective.

Imagine a resin 3D printer build chamber spacious enough to fit four standard carry-on suitcases side-by-side with room to spare. That is the sheer scale of 3D Systems’ newly launched SLA 825 Dual.

While the company frames it as a 20% upgrade over their previous model (SLA 750 Dual), the real story is just how massive this machine is compared to the desktop units we know.

Overall, the SLA 825 clearly targets industrial throughput and part-size improvements. Yet, 3D Systems is also being more explicit about resolution and feature-size claims for the SLA 825 (50–150 µm layer thickness; XY feature size to 0.0127 mm) than it ever was with the SLA 750, which focused on “2000 dpi” and general accuracy.

“The SLA 825 Dual will continue 3D Systems’ nearly 40-year leadership in high-throughput SLA manufacturing,” the company says. Need we remind you that 3D Systems invented SLA decades ago.

3D Systems hasn’t yet disclosed the throughput, nevertheless is calling the SLA 850 its “most advanced” large-frame stereolithography printer aimed at key markets, such as motorsports, foundries, and service bureaus.

The new machine also introduces a more streamlined workflow, improving ease of use and maintenance. In keeping with modern industrial system design, the 825 Dual is upgradeable, allowing customers to adopt future hardware or software improvements as they’re released.

Notably, new software, available to customers as an add-on to the 3D Sprint printer management software, is focused on casting applications. ArrayCast, enables you to create customized casting trees, complete with configurable runners, sprues, and end effectors tailored to your workflow. 3D Systems says ArrayCase can deliver up to 10x faster production cycles by digitally assembling casting trees before printing begins, eliminating bottlenecks caused by manual processes. It eliminates the hand gluing or wax welding required in cast making that can introduce human error.

To feed this new monster resin printer, 3D Systems is launching new materials including Accura SbF and Accura Xtreme Black. The SbF is designed for investment-casting workflows and targets patterns that must be dimensionally stable and burnout cleanly. It is antimony-free, which improves suitability for casting of high-performance metals (including nickel-based superalloys and titanium). The material also offers a low-viscosity resin that drains quickly and cures to a high modulus, making it easier to handle and prepare for shelling.

Accura Xtreme Black is aimed at functional prototyping applications, offering parts with production-like aesthetics (deep black color), robust mechanical properties, and reduced finishing needs.
