3D Systems Launches SLA 825 Dual With Dual-Laser Technology

Key Takeaways

• Dual 4 W lasers aim to boost SLA throughput
• Build volume 830 × 830 × 550 mm, 22% larger than prior models
• Claimed up to 25% faster builds versus previous SLA printers
• Lower‑power lasers keep system cost competitive for service bureaus
• Larger build area reduces part count per job, increasing revenue potential

Pulse Analysis

Stereolithography (SLA) has long been the gold standard for high‑resolution resin printing, but speed has remained a persistent bottleneck. 3D Systems, the inventor of SLA technology, leverages its deep expertise to introduce the SLA 825 Dual, the first consumer‑grade printer to employ two simultaneous lasers. By splitting the build area between two 4 W sources, the system can cure two distinct regions at once, a concept borrowed from metal powder‑bed fusion where multi‑laser heads are commonplace. This architectural shift signals a maturation of SLA, moving it closer to the productivity levels traditionally reserved for metal additive processes.

The SLA 825 Dual’s specifications underscore its production focus. Its 830 × 830 × 550 mm build envelope expands the printable footprint by roughly 22%, enabling larger prototypes and end‑use parts without the need for multiple machines. While the dual‑laser setup theoretically could double throughput, 3D Systems advertises a more modest 25% speed increase, likely reflecting the use of lower‑power lasers that balance energy delivery with hardware cost. The modest gain still translates into meaningful time savings on sizable jobs, especially when combined with the machine’s larger volume, which reduces the number of separate prints required for a given production run.

For service bureaus and in‑house manufacturing labs, the SLA 825 Dual offers a compelling value proposition. Faster builds and a larger build plate mean higher part‑per‑day capacity, directly boosting revenue potential and reducing order turnaround. Because the system avoids the expense of high‑power lasers, its price point remains accessible for shops seeking to scale resin production without a massive capital outlay. As the industry pushes toward higher throughput and lower per‑part costs, dual‑laser SLA printers like the 825 Dual could become the new standard for high‑volume, high‑precision additive manufacturing.
