Laser glass and crystal sub-surface engraving technology is currently a relatively advanced and popular method of engraving inside glass in the world. It doubles the frequency of pulsed YAG strong laser, outputs green laser with a wavelength of 532nm, and focuses on the inside of glass and crystal to produce micron The vaporization burst point of magnitude size is controlled by the computer to control the spatial position of the burst point in the vitreous body, forming a colorful three-dimensional image inside.

3D Laser Subsurface Engraving Machine

In order for a laser to be able to engrave glass and crystal, its energy density must be greater than a certain critical value, or threshold value, to destroy the glass, and the energy density of the laser at a certain point is related to the size of its spot at that point. The smaller the spot is, the smaller the same laser beam is The greater the energy density generated in the place. In this way, through proper focusing, the energy density of the laser can be lower than the damage threshold of the glass before it enters the glass and reaches the processing area, and exceeds this critical value in the desired processing area, and the laser generates pulses in a very short time. Its energy can instantly heat and crack the crystal, resulting in tiny white spots, carving a predetermined shape inside the glass, while the rest of the glass or crystal remains intact.

Laser subsurface engraving machine is an intelligent internal engraving tool integrating laser technology, mechanical design technology, computer technology, electronic technology, 3D control technology and transmission technology.

3D Laser Subsurface Engraving Machine for Custom Crystal and Glass


Small size: It adopts integrated design, small size and light weight.

Simple, flexible and convenient operation: The software interface is user-friendly and easy to learn. The integrated automatic centering function makes it convenient for the operator to place the crystal.

Strong adaptability: According to the mobile requirements of the machine, the core components are equipped with an anti-shock system, which can effectively prevent damage to the core components of the machine due to accidental impact during equipment transportation and use.

Fast engraving speed: With 2000Hz laser head, the general engraving speed can reach more than 1800 dots/second, saving engraving time.

3D Laser Subsurface Engraver for Crystal and Glass

High stability, delicate engraving effect. Adopting advanced air-cooled semiconductor end-pumped solid-state laser technology, the beam quality is good, the stability is high, and the engraved point effect is delicate.

Support multiple data formats: The software came with it supports data files in multiple formats such as dxf, cad, bmp, jpg, etc., and has good compatibility.

Environmental protection, low noise: No compressor, water pump and high-power fan, no pollution, because the laser engraves inside the glass or crystal without any damage on the surface, so no dust, gas and other pollutants are emitted.

2D and 3D functions are available at the same time. Any text and pattern can be engraved inside the glass and crystal.

3D Laser Engraving Machine

Using the five-axis linkage computer automatic control system, the engraving precision is higher, the effect is good and the operation is simple.

Both batch production and individual processing are possible. During mass production, one person can operate several sets of equipment, saving manpower.

Optional 3D camera for making personalized 3D portraits.

Combined with industrial production lines and industrial robots to realize subsurface engraving automation.


Laser sub-surface engraving machine is suitable for fine internal engraving in crystal glass, quartz glass, optical glass, ordinary glass and tempered glass.

Laser subsurface engraving machine is used to engrave any 3D graphics inside the crystal body, such as flowers, birds, fish, people, beautiful natural scenery and other various animals and plants. The good optical properties of the crystal make the sculpture exquisite, such as in the sky and in the water.

Laser subsurface engravers are used for creating glass crafts, souvenirs, and detailed engraving of interior and surface patterns on decorative glass. In fact, most of the handicrafts that are usually seen are not real crystals, but artificial crystals. Laser is the most useful tool for internal carving of artificial crystal (also known as crystal glass). Using laser engraving technology, the 2D or 3D pattern is engraved on the inside of the crystal glass. It can etch 2D/3D portraits, names, hand and footprints, trophies and other personalized gifts and souvenirs, and can also mass produce 2D/3D models of animals, plants, buildings, cars, ships, airplanes and 3D scene displays.

A great laser engraver to make personalized gifts with crystals. Only need a picture or a screenshot, it will turned out a nice and clear 3D graphic on the subsurface of crystal. I will try subsurface engraving on cell phone backs, screens, cases, covers and shells made of glass, ceramic or crystal in the future. All in all a great crystal engraving machine worth buying for both business starters and custom shop owners.
