The Ortur Laser Master 2 S2 SF is a 5.5W (5,500mW) diode laser engraving and cutting machine built for makers, hobbyists and small businesses that need fine detail on a large surface. Its short-focus, optically compressed 0.12 x 0.15mm spot renders crisp text, photos and intricate artwork, while the generous 390 x 410mm (15.4" x 16.1") bed handles big projects and batch production at speeds up to 5,000mm/min. Engrave 100+ materials — wood, bamboo, leather, paper, acrylic, coated glass, stone and coated or oxidized metal — and cut up to 6mm pine in one pass with air assist. The plug-and-play USB connection works with LightBurn and free LaserGRBL on Windows, macOS and Linux, opening JPG, PNG, BMP, DXF, NC and SVG files. A rigid, modular aluminum frame keeps engravings sharp through long runs, and built-in safety protections — tilt and displacement auto-stop, USB-disconnect shutoff, long-idle auto-off and a 97% UV-filtering shield — let you work with confidence (eye protection recommended). Ideal for personalized gifts, signage, crafts and product customization. | Ortur | | -LaserMaster2 S2SF 5.5W DiodeLaserEngraver,Cutter-Black | Best Buy
