About these items High - performance engraving: All laser engravers can engrave and cut over 100 types of materials. They feature innovative laser technology with spot compression, a 0.08 x 0.08 mm laser beam size for concentrated energy, and high - speed engraving up to 10,000 mm/min using a stepper motor and synchronous belt drive. Power and capacity: Different power levels are available (5W, 10W, 20W). The 10W and 20W models can cut wood up to 5 mm thick. All have a laser head lifespan of over 10,000 hours at 80% power and offer relatively spacious engraving areas. Air - assist compatibility: All support air - assist function (air pump included only in G3 model). Air - assist improves cutting efficiency, avoids dark edges, and lowers surface temperatures during engraving and cutting, resulting in clean, precise edges. User - friendly and compatibility: They connect to the computer via USB and are compatible with popular software like LightBurn and LaserGRBL, supporting iOS, Windows, or Linux systems. They come with features like a cable management system, eye - protecting filters, and some have an emergency stop switch for good operation. Assembly and trial materials: Some models like the 5W - powered one have a simplified modular design for easy assembly with detailed instructions. All come with a set of trial wood and acrylic plates, along with necessary tools and accessories.
