How Does 3D Subsurface Laser Crystal Engraving Machine Work?

The principle of 3D subsurface laser crystal engraving machine is not the phenomenon of light interference, but because the laser intensity at the focus point is high enough. Although transparent materials are generally transparent to the laser and do not absorb laser energy, they will produce a non-linear effect and absorbs a large amount of energy in a short time to produce a micro-burst at the focal point, and a large number of micro-burst points form an internal engraving pattern.

The laser subsurface engraving patterns of crystal and glass are made by a computer-controlled laser inner engraving machine. In fact, most of the crafts commonly seen are not real crystals, but artificial crystals. “Laser” is the most useful tool for “internal engraving” of man-made crystals (also called “crystal glass”). Using laser subsurface engraving technology, the plane or three-dimensional pattern is “engraved” in the crystal glass.

When laser internal engraving, there is no need to worry that the incoming laser will melt the substance on the straight line, because the laser maintains the form of light energy when passing through a transparent object and does not generate excess heat. Only at the point of interference will it be transformed into internal energy to melt the substance.

How Much Does A 3D Laser Crystal Engraving Machine Cost?

3D laser crystal engravers typically cost anywhere from $17,900 to $22,000, depending on the laser power and table size. Based on the make and model of your 3D crystal engraving machine, you can expect to pay around $19,200 for a standard crystal engraver and around $23,800 for a premium type with shipping costs.

How to Laser Engrave Crystal?

The outside of the crystal is smooth and hard, without the slightest gap. How is the pattern inside the crystal made?

In fact, these glass and crystal crafts are made by a computer-controlled green laser engraver. Laser glass and crystal engraving technology is currently the most advanced and popular glass engraving processing method in the world. It uses a green laser with a wavelength of 532nm to focus inside the glass and crystal. The computer controls the spatial position of the burst point in the vitreous body, forming a colorful three-dimensional photo inside. When the laser beam is engraving, it will follow the preset optical path to reach the top of the crystal, until the laser enters the crystal, its energy density must be less than the destruction threshold (a certain critical value that destroys the transparent material). After entering the crystal, its energy density must be greater than the destruction threshold. During the engraving process, the laser is properly focused (the energy density of the laser at a certain point is related to the size of the spot at that point. For the same laser, the smaller the spot is, the greater the energy density is.) to make its energy The density exceeds the failure threshold of the material. Because the laser generates pulses in a short period of time, its energy can cause the material to be thermally broken in an instant, resulting in extremely small white dots. Arrange the dots in a regular manner to form the pattern we need. The smaller the focus point and the more precise the control, the finer and more lifelike graphics we get. It is suitable for fine engraving in crystal glass, quartz glass, optical glass, ordinary glass and tempered glass. Engrave flat or three-dimensional patterns in transparent materials such as crystal and glass. The rest of the glass or crystal is left intact as it is.

So, how to obtain 3D designs is thanks to 3D flash photography technology, which has absolute advantages in shooting human bodies. It can obtain high resolution within 0.01 seconds and obtain accurate 3D data of faces. 3D flash light can be connected with ordinary 2D digital camera to project special raster code on the surface of the object, and the coded picture is captured by the digital camera. Through special decoding software, the coded picture is analyzed to find out the 3D information of the X, Y and Z axes of the photo. In this step, the processed portrait is a 3D mesh portrait composed of grids, and the next step is to give the face skinned and tinted. After completion, a 360-degree 3D full portrait was created in the computer. The computer then enters the information into the 3D subsurface laser crystal engraving machine, and the perfect personalized portrait will be engraved.


The 3D laser crystal engraver solves the problem of slow engraving speed, unstable system operation, missing laser points, insufficiency of pattern and text designing software, use of computer interface control cards, uneven laser explosion points, imperfect automatic control devices, and low cost performance of equipment. The efficiency, accuracy, maintainability, versatility and safety of the system are comprehensively improved.

3D subsurface laser crystal color engraving is expected to be realized.

It is inevitable that crystal engravings will become richer in color. According to the principle of the three primary color palette, the micro-control circuit controls the lamps of several colors respectively, and mixes the colors on the “interior engraving” photo to change a variety of brilliant colors, so that the original white interior engraving photo presents a colorful effect.


The 3D laser crystal engraving machine can only be used for crystal and glass, and the engraving scope is 300mm*400mm*130mm. Of course, you can customize the table size according to your business needs, but the price will also be higher. The parameter setting is a bit difficult. In addition, the price is a bit high, starting at $18,000.
