Atomstack Glacier

Diode laser engravers tend to lose power as they heat up, and air cooling only goes so far. Atomstack's answer with Glacier is liquid cooling: according to the maker, the system holds the laser module at 30℃, allowing 24-hour continuous operation without output drop and five times the lifespan of air-cooled machines.

Two lasers, one cooling loop

The headline figure is 120W of actual output. Atomstack says it can cut 40mm solid wood or 30mm acrylic in a single pass, with second-generation COS packaging compressing the beam to a 0.15×0.15mm spot. Output runs at 100W in standard mode, with a turbo mode raising it to 120W for thicker stock.

Alongside it sits a 4W IR laser module at 1064nm, which the maker describes as the first water-cooled IR module. With a 0.04×0.04mm spot, it is claimed to engrave deeply into more than 300 materials, including metal marking and fine stone work, operate between -10℃ and 40℃, and last 100,000 hours.

Workspace, control and safety

• 800×800mm working area, sized for full MDF sheets and composite panels without splitting jobs
• Power-loss recovery that resumes from the point of interruption
• Built-in touchscreen for offline jobs without a PC
• 4-in-1 real-time monitoring of temperature, water level, flow and faults, with a safety stop in 0.1 seconds
• Optional fully enclosed B4 enclosure for capturing smoke and fumes, with 360-degree visibility
• Atomstack Studio on PC and a smartphone app, plus compatibility with LightBurn and LaserGRBL
• Multi-machine control: one PC can run several Glacier units on the same or different jobs

Taken together, Atomstack positions Glacier as both a hobbyist tool and light production equipment, with the cooling system as the feature that makes the rest of the specification sheet credible over long sessions.
