This is the TTS-55 PRO, the upgraded version of the TTS 55, with a laser power of 5500mW.

32-bit Motherboard: The motherboard features a 32-BIT dual-core MCU for faster processing, with an engraving speed up to 10,000mm/min. The laser can engrave both online and offline (via TF card). With the built-in Wi-Fi module, you can also use a mobile phone app or computer web interface for engraving.

Perfectly Compatible System: Use LaserGRBL or LightBurn (the most popular paid carving software, very easy to use). Supports Windows XP, 7, 8, 10 (with LaserGRBL), and Mac OS, and Linux (with LightBurn).

Advanced Laser Technology: The TTS-55 PRO laser module uses the latest LD+FAC+C-Lens compression spot technology. It has a fixed focus with a focal length of only 23mm. Compared to long-focus lasers, this short-focus laser has stronger engraving and cutting abilities. Engraving accuracy is 0.1mm.

Engraving and Cutting Capability: The TTS-55 laser can engrave wood, plastic, paper, leather, bamboo, sponge paper, alumina, stainless steel, chevron board, acrylic, glass, and more. It can cut up to 5mm plywood, 3mm acrylic board, 3mm carton, 0.7mm leather, and more. The working area is 300x300mm.
