The OMTech Solis Duo was designed to break that cycle entirely. Announced in August 2025, it’s a compact dual-laser engraver that integrates a fiber laser (1064nm) and a blue diode laser (455nm) in a single, Class 1 enclosed chassis. Depending on the configuration, you get a 20W, 30W, or 50W fiber laser paired with a 20W or 40W diode laser. The result is a machine that can engrave stainless steel, brass, and titanium with the fiber side, then instantly switch to wood, leather, or acrylic with the diode side — all without changing setups.

After spending time with the Solis Duo — running test engravings on metal, wood, leather, and acrylic — here’s the honest assessment of what this machine does well, where it falls short, and whether it’s the right investment for your workshop.

Specifications at a Glance

The Dual-Laser Configuration: One Machine, Two Worlds

The Solis Duo’s defining feature is its true dual-laser architecture. Unlike modular systems that require physically swapping laser heads, the Duo integrates both lasers into a single galvo-based system. Switching between them is instantaneous — you’re not retooling, you’re not recalibrating, you’re just clicking a button in the software.

This isn’t just a marketing gimmick. In practice, the ability to engrave a metal keychain and a wooden plaque in the same session, without moving materials between machines, genuinely changes the workflow. As one user put it: “We replaced a benchtop fiber and a separate diode with the Duo. Shared focus and the camera make mixed metal + wood jobs much simpler”.

10,000 mm/s Galvo Speed: Industrial Throughput on Your Desktop

The Solis Duo uses a galvanometer system — high-speed mirrors that steer the laser beam instead of moving a heavy mechanical head. The result is engraving speeds up to 10,000 mm/s.

What does this mean in practice? Users coming from gantry-based diode lasers at 600 mm/s describe the difference as “instant”. Logos, QR codes, and batch production jobs that used to take minutes now finish in seconds. The 16MP HD camera further streamlines batch processing, allowing quick visual alignment and job setup.

250×250mm Work Area: The Largest in Its Class

At 250 × 250 mm, the Solis Duo’s work area is the largest in its category. This is spacious enough to handle multiple jobs at once — ideal for batch production of small items like keychains, tags, and jewelry.

If you need even more space, the optional conveyor system extends the work area up to 250 × 900 mm — the longest in its class. The optional rotary axis attachment enables engraving on cylindrical objects like tumblers, mugs, and rings.

0.002 mm Accuracy: Precision That Rivals Industrial Machines

The Solis Duo delivers 0.002 mm engraving accuracy. This level of precision ensures even the finest text or design element is rendered with clarity — whether you’re engraving serial numbers on metal parts or detailed artwork on wood.

The fiber laser’s pulse width ranges from 80–100 ns, and the modulation frequency spans 30–60 kHz. This flexibility allows fine-tuning for different materials and applications.

Class 1 Enclosed Safety: Home-Studio Ready

The Solis Duo features a fully enclosed, Class 1 FDA-certified chassis with a tinted viewing window. This means the machine contains laser radiation and fumes during operation, making it safe for indoor workshops, craft studios, home-based businesses, and classrooms.

This is a significant advantage over open-frame diode lasers that require dedicated workshops and safety goggles. The Solis Duo can sit on a workbench in a spare room without turning it into a hazmat zone.

Performance: What Can It Actually Do?

Metal Engraving (Fiber Laser): The fiber laser is where the Solis Duo truly shines. On stainless steel, black marks come out crisp and high-contrast. The 50W fiber configuration delivers deep, permanent engraving that’s suitable for industrial applications like serial numbers, QR codes, and part identification.

One user reported: “Stainless black marks look crisp at 150×150 lens”. The machine’s 0.002 mm accuracy ensures fine detail is preserved even on small metal surfaces.

Wood and Leather (Diode Laser): The 20W or 40W diode laser handles wood, leather, and acrylic with authority. One user noted: “The 20W diode handles 3 mm ply well with air assist”. For thicker materials, users report that a dedicated CO₂ laser is still the better choice — but for most everyday engraving and light cutting, the diode is more than adequate.

Acrylic: The diode laser handles dark/opaque acrylic well, but clear acrylic is a physics problem — diode lasers can’t cut it. For clear acrylic, you’d need a CO₂ laser. This isn’t a Solis Duo limitation — it’s a fundamental limitation of diode technology.

Batch Production

With the 10,000 mm/s galvo speed and the 16MP camera for visual alignment, the Solis Duo is ideal for batch processing. Users report that batch mode with the camera is a significant time-saver.

Competitive Landscape: How the Solis Duo Stacks Up

Summary

The OMTech Solis Duo is the most practical dual-laser engraver for creators who work across both metals and non-metals. It combines two powerful laser sources — fiber and diode — in a single, Class 1 enclosed chassis that’s safe for home studios and small workshops. The 10,000 mm/s galvo speed and 0.002 mm accuracy deliver industrial-grade throughput and precision. The 250×250mm work area is the largest in its class. And the three-configuration lineup offers a clear upgrade path that competitors lack.

But for small business owners, Etsy sellers, sign makers, and serious makers who need one machine that does it all — metal and wood, acrylic and leather, batch production and custom one-offs — the Solis Duo delivers.
