The GLMM-1W is a 3D laser internal engraving machine built on a 300 × 400 mm engraving platform base and developed for smaller, personalized work. It is mainly used by wedding photo studios, advertising gift suppliers, tourist attractions and internal engraving workshops. Its key advantages are its compact size, light weight, portability and affordable price, which make it accessible to a wider range of users and start-up businesses.

The machine engraves text and patterns inside transparent materials such as acrylic, crystal and glass. With the supplier’s technical improvements it can also perform basic laser engraving on the surface of non-transparent materials including metals and non-metals, making it a versatile single-machine solution. Both 2D and 3D work is supported: flat photos, children’s hand and foot prints, trophies and medals, 3D portraits and a range of 3D models. The integrated Z-axis and XY-axis design improves engraving precision and quality, and a 368-specification crystal portrait can be completed in about five minutes.

Because the engraving is created inside the material without damaging the surface, the process produces no dust or pollution emission, and the finished patterns cannot be removed by acids, alkalis, solvents, high temperature or friction, which also makes the machine suitable for anti-counterfeiting marking. The machine runs on 220V ±10%, 50Hz with air cooling and an output of about one kilowatt-hour per hour, and the laser module has a rated life of 20,000 hours. It measures approximately 500 × 600 × 600 mm and weighs approximately 30 kg. Please note that the machine should be installed in a clean, dust-free environment free of vibration sources, and that the standard configuration can be customized — including laser parameters and performance — for special requirements.
