3D Laser Engraving in Glass & Crystal

When it comes to laser engraving, you may already be quite familiar with the technology. Through the process of photoelectric conversion in the laser source, the energized laser beam removes a thin layer of surface material, creating specific depths that result in a visual 3D effect with color contrast and a tactile sense of relief. However, this is typically classified as surface laser engraving and is fundamentally different from true 3D laser engraving. In this article, we will take photo engraving as an example to explain what 3D laser engraving (also known as 3D laser etching) is 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.

Common applications of internal laser engraving

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

Technology Support and Market Prospect

More fortunately, the green laser technology has been around for a long time and is equipped with mature technology support and reliable components supply. So the 3d subsurface laser engraving machine can provide manufacturers a super excellent opportunity to expand business. That is a flexible creation tool to realize the design of unique memorial gifts.
