This test used a GM-100 fiber laser with LightBurn software to engrave a brass belt buckle. The goal was to check whether the machine could process a grayscale relief-style design on the brass surface.
1. Test Goal
The test was carried out to verify the relief engraving performance of the GM-100 on brass. The required result was a detailed engraved design with a good final appearance.
2. Test Requirement
The sample was a brass belt buckle. The engraving process needed to create a detailed skull and motorcycle relief-style design.

6. Test Conclusion
This brass belt buckle relief engraving test achieved the recorded test requirement using the GM-100. The parameter screenshots show a relief engraving workflow with a cleanup layer, which supports detailed grayscale-style engraving on a brass accessory surface.
This type of result may be useful for custom belt buckles, decorative metal accessories, personalized gifts, commemorative products, and small-batch metal craft samples. Before batch production, the final parameter values should be confirmed with the same material, artwork file, lens setup, and marking software.
