AtomStack Glacier 120W Water-Cooled Diode Laser Engraver

AtomStack Glacier 120W Water-Cooled Diode

120W Water-Cooled Professional Laser Cutter

The AtomStack Glacier is the world's first water-cooled diode laser engraver, delivering a true 120W laser output sustained for 24 hours straight with zero power decay. Its precision-engineered water-cooling system holds the laser at a steady 30°C, enabling true 24/7 operation without thermal throttling—something air-cooled systems simply cannot match. The Glacier cuts through 30 mm solid wood and 30 mm acrylic in a single pass, making it the most powerful diode laser cutter available.

With an expansive 800 × 800 mm working area, the Glacier handles full-size MDF boards, large woodwork, and industrial prototypes in one piece—eliminating alignment errors from piecing smaller sections together. The second-generation COS packaging technology achieves a laser spot as small as 0.15 × 0.15 mm, delivering significantly higher precision than typical high-power lasers. With an optional IR4 infrared module for metal engraving and compatibility with 300+ materials, the Glacier is built for demanding production workflows and serious commercial operations.

FAQ's

Frequently Asked Questions

What is the working area of the AtomStack Glacier 120W?
The Glacier provides an 800 × 800 mm working area, allowing large sheets and full-size projects to be processed without repeatedly repositioning the material.

Why does the Glacier use water cooling instead of conventional air cooling?
The Glacier uses an integrated water-cooling system designed to maintain the laser at approximately 30°C during operation. AtomStack positions the system for sustained, continuous operation and reduced thermal slowdown compared with conventional air-cooled diode systems.

Can the Glacier operate continuously for 24 hours?
Yes. AtomStack specifically states that the water-cooled system is designed for 24/7 operation, with the 120W configuration capable of sustaining its laser output for extended production without the thermal slowdown associated with air-cooled systems.

Can the Glacier engrave metal?
The standard diode laser is not a dedicated metal-marking laser. However, the Glacier can be fitted with AtomStack's optional IR4 4W infrared laser module, which adds metal and plastic engraving capabilities.
