Atomstack Glacier 120W vs Atomstack Glacier 90W Water-Cooled Diode
Technical comparison · Diode laser (405–460 nm)
Both have an 800 × 800 mm bed, a diode source and autofocus, so the choice comes down to power, 120 W against 90 W, and the wood thickness each is rated to cut, 40 mm against 30 mm.

| Software notes | The system is fully compatible with LightBurn, the industry-standard software for advanced vector preparation and control, and AtomStack Studio, the manufacturer's proprietary solution. It also features a built-in touchscreen for offline control, allowing complex jobs to be started without the need for a constantly connected computer. | The system is compatible with leading laser cutting and engraving software, such as LightBurn and LaserGRBL. The machine offers fully offline operation capabilities via its built-in touchscreen display, allowing users to manage jobs locally without the need for a permanently tethered computer during extensive runs. It supports standard G-code files and can be expanded with additional modules, such as the infrared laser for processing metals. |
The differences that matter
- Power and cut: 120 W against 90 W; in wood up to 40 mm against 30 mm (manufacturer's rated values) → boards between 30 and 40 mm are within the rated range only on the 120W.
- Price: €2,199 against roughly €2,000 → about €200 less for the 90W.
Which one to choose
Choose Glacier 120W if…
You cut thick solid wood and acrylic and want to do it in a single pass: the maker rates up to 40 mm in solid wood and 30 mm in acrylic. The compromise is price, about €200 more (€2,199 against roughly €2,000).
Choose Glacier 90W Water-Cooled Diode if…
You work wood up to 30 mm and want a water-cooled machine for about €200 less. The compromise: 30 W less power and a wood cutting limit 10 mm lower.
