3D Laser Engraving in glass & crystal
Surface laser engraving
VS
Sub-surface 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), 3D crystal engraving or inner laser 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
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.
What you can benefit from Subsurface Laser Engraving
✦ No heat-affected on the materials with the cold treatment from green laser
✦ Permanent image to be reserved does not wear due to internal laser engraving
✦ Any design can be customized to present a 3D rendering effect (including the 2d image)
✦ Exquisite and crystal-clear laser engraved 3d photo crystals
✦ Fast engraving speed and steady operation upgrade your production
✦ High quality laser source and other components allow less maintenance

One key point need to note:
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.
Green laser engraver
Supported Laser Technology - green laser
The green laser of 532nm wavelength lies in the visible spectrum which presents the green light in the glass laser engraving. The outstanding feature of the green laser is the great adaptation for heat-sensitive and high-reflective materials which have some troubles in other laser processing, such as glass and crystal. A stable and high-quality laser beam provides reliable performance in 3d laser engraving.
As the represent of cold light source, UV laser get wide application due to high quality laser beam and steady operation. Usually glass laser marking and engraving adopt the UV laser engraver to achieve customized and fast processing.

Choosing a laser marking machine that suits your production involves considering several key factors. First, identify the materials you'll be marking, as different lasers are suitable for various surfaces. Assess the required marking speed and precision for your production line, ensuring the selected machine meets those specifications. Consider the laser wavelength, with fiber lasers being ideal for metals and UV lasers for plastics. Evaluate the machine's power and cooling requirements, ensuring compatibility with your production environment. Additionally, factor in the size and flexibility of the marking area to accommodate your specific products. Finally, assess the ease of integration with your existing production systems and the availability of user-friendly software for efficient operation.
