Atomstack A20 Pro V2 vs Ortur Laser Master 3 10W
Technical comparison · Diode laser (405–460 nm)
Two 455 nm diode lasers at close indicative prices (€450 and €375). What decides is rated power, 20 W against 10 W: the rest is €75 and a few millimetres of bed.

| Software notes | The software compatibility of the device is extensive and aligns with the industrial standards of the maker sector. It natively supports both LaserGRBL, a free and open-source option suitable for basic engraving operations, and LightBurn, the most popular paid professional platform for advanced management of layers, cutting parameters, and complex vector formats. Control can be managed directly via a wired USB connection from a computer or in offline mode, using memory cards to load processing files. The machine responds to standard G-code commands, allowing experienced users fine customization of acceleration and speed parameters through the configuration of the internal firmware, without constraints linked to proprietary and closed-source cloud ecosystems. | Natively compatible with LightBurn and LaserGRBL for desktop control. It also features a proprietary mobile application via Wi-Fi connection for basic management and rapid file sending. |
The differences that matter
- Rated power 20 W vs 10 W → the A20 Pro V2 leaves more margin in speed or passes on the same material (manufacturer-declared values).
- Bed 400 × 365 mm vs 400 × 400 mm → the Laser Master 3 takes a part 35 mm wider on the short side.
- Software: the A20 Pro V2 also has proprietary software besides LightBurn; the Laser Master 3 has a mobile app over Wi-Fi for sending files.
Which one to choose
Choose A20 Pro V2 if…
Engraving large surfaces and cutting in fewer passes: with double the rated power you can raise the speed, declared up to 24,000 mm/min, or cut the passes on the same material. It costs more and the short side of the bed is shorter.
Choose Laser Master 3 10W if…
Engraving signs, personalised items and jobs across the whole bed, where 10 W is enough and the €75 saved counts; declared speed goes up to 20,000 mm/min and files are sent from the phone over Wi-Fi with the app. You accept half the rated power, so less margin on cuts.
