Atomstack Swift vs Ortur LM3 40W
Technical comparison · Diode laser (405–460 nm)
Swift and LM3 40W start from very different budgets (€215 vs €700) and aren't aimed at the same buyer. The second's name references 40W, but the declared rated power spec is 20W — a distinction that matters more than the model name when cutting capacity is the deciding factor.

| Software notes | The AtomStack Swift supports the most widely used laser control software, including LaserGRBL (free, Windows only) and LightBurn (paid, compatible with Windows, macOS, and Linux). It connects via USB or Wi-Fi, providing excellent flexibility for sending g-code files directly to the machine. | The LM3 uses firmware based on the open GRBL protocol, compatible with LightBurn (diode license ~$60 one-time), LaserGRBL (free, open-source), and the proprietary Ortur iOS/Android app with selectable novice and advanced modes. LightBurn offers advanced variable power control, path optimization, and optional camera alignment; LaserGRBL covers basic engraving tasks at no additional cost. The open GRBL protocol ensures compatibility with third-party tools and standard G-code generators. Communication is via USB; the Ortur app allows remote job launching via Wi-Fi without a connected PC. |
The differences that matter
- Price: €215 for the Swift vs €700 for the LM3 40W — nearly triple.
- Declared cut depth: up to 15 mm (pine), 10 mm (plywood), 8 mm (black acrylic) on the LM3 40W; no figure available for the Swift.
- Work area: 400×380 mm on the LM3 40W vs 300×300 mm on the Swift.
- Rated power: 20W declared on the LM3 40W despite the "40W" in its name; not available for the Swift.
Which one to choose
Choose Swift if…
Pick the Swift if budget is the top priority and you're engraving thin materials: at €215 it's among the cheaper options in the category, though work area (300×300 mm) and power stay modest.
Choose LM3 40W if…
Pick the LM3 40W if you need to cut, not just engrave: the spec sheet declares cut depths up to 15 mm on pine, 10 mm on plywood and 8 mm on black acrylic — figures not available for the Swift. Work area (400×380 mm) is also larger.
