Wonderful Art from 3D Laser Engraving
Speak of laser engraving, you maybe have a great knowledge of that. By means of the photovoltaic conversion happening to the laser source, the excited laser energy can remove partial surface materials to create the specific depth, producing a visual 3d effect with color contrast and concave-convex sense. However, that is usually regarded as surface laser engraving and has an essential difference from real 3D laser engraving. The article will take the photo engraving as an example to show you what is 3D laser engraving (or 3D laser etching) and how it works.

What is 3D laser engraving
Like the pictures shown above, we can find them in the store as gifts, decorations, trophies, and souvenirs. The photo seems floating inside the block and presents in a 3D model. You can see it in different appearances at any angle. That's why we call it 3D laser engraving, subsurface laser engraving (SSLE), or 3D crystal engraving. There is another interesting name for "bubblegram". It vividly describes the tiny points of fracture made by laser impact like bubbles. Millions of tiny hollow bubbles constitute the three-dimensional image design.
How does 3D Crystal Engraving Work
Sounds amazing and magic. That's exactly a precise and unmistakable laser operation. Green laser excited by the diode is the optimal laser beam to pass through the material surface and react inside the crystal and glass. Meanwhile, every point size and position need to be accurately calculated and precisely transmitted to the laser beam from 3d laser engraving software. It is likely to be 3D printing to present a 3D model, but it occurs inside the materials and has no impact on the external material.

Some photos as a memory carrier are usually engraved inside the crystal and glass cube. The 3d crystal laser engraving machine, although for the 2d image, it can transform it into a 3d model to provide instruction for the laser beam.

Adaptable materials
The green laser can be focused within the materials and positioned anywhere. That requires materials to be high optical clarity and high reflection. So crystal and some types of glass with an extremely clear optical grade are preferred.
- Crystal
- Glass
- Acrylic
