Introduction
This is a 3D inner engraving test on a crystal block using the Cloudray UV Pro 5W UV laser. The test focused on engraving a jellyfish-style 3D model inside the crystal, creating a visible suspended 3D effect.
The total marking time for this test was approximately 11 minutes.
1. Test Goal
The purpose of this test was to verify whether the UV Pro 5W UV laser could complete a clean and detailed 3D inner engraving inside a crystal block.
The test needed to confirm whether the machine could reproduce the main structure of the jellyfish model, including the body shape and flowing tentacle details, while keeping the engraving positioned correctly inside the crystal.
2. Test Requirement
The requested sample was a rectangular crystal block. The required effect was 3D inner engraving based on a jellyfish 3D model file.
The final result needed to show a clear three-dimensional visual effect inside the crystal, with the engraved points forming the jellyfish shape from the internal structure.

5. Test Result
The crystal inner engraving test was completed successfully. The total marking time was approximately 11 minutes.
The jellyfish model was engraved inside the crystal block, forming a visible 3D structure within the transparent material. The main body and tentacle areas were reproduced clearly.
6. Test Conclusion
The test confirmed that the UV Pro 5W UV laser can be used for crystal 3D inner engraving projects, especially for decorative gifts, custom crystal displays, 3D model engraving, and personalized crystal artwork.
For future production, the final result may vary depending on the crystal size, material quality, model complexity, point spacing, focus calibration, and engraving depth settings. When working with a new crystal size or a more complex 3D model, it is recommended to run a small test first and adjust the point spacing, dwell time, and depth settings to balance engraving clarity and processing time.
