LM3 40W

Ortur OLM3 40W / LU3-40A 2023
Diode laser (405–460 nm) F2 · Intermediate

The $629.99 Ortur LM3 40W sits between the Sculpfun S30 Ultra 33W (~$550) and the xTool D1 Pro 40W (~$749), offering a 400x380mm workspace and a top speed of 20,000mm/min. The package includes a 50L air pump with air assist integrated into the laser module, an accessory that competitors in the same price range price separately for $30–60. The typical user profile is a semi-professional maker producing wood or acrylic parts several times a week and requiring single-pass cutting up to 15mm on pine without reconfiguring the setup. The main limitation is the open-frame design: without a dedicated enclosure, managing fumes and laser safety is left up to the operator.

Software

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.

Reviews from those who use this machine every day will be available in the next version of the platform.
