3D Laser Inner Engraving Machine
The SANKEN SKLE Series 3D Laser Inner Engraving Machine is designed to create decorative patterns inside transparent glass and crystal without mechanically cutting grooves into the surface.
A computer-controlled laser forms small internal points that make up 2D or 3D images. This process can be used for decorative glass panels, crystal products and customized artwork.
Five models are available: SKLE-1218, SKLE-1325, SKLE-1530, SKLE-2030 and SKLE-2040.
The series offers maximum processing sizes from 1200 × 1800 mm to 2000 × 4000 mm, with a laser wavelength of 532 nm and engraving speeds of 180,000–480,000 dots per minute.
3D Laser Inner Engraving Machine
The SANKEN SKLE Series 3D Laser Inner Engraving Machine is designed to create decorative patterns inside transparent glass and crystal. Using computer-controlled laser technology, the machine produces internal points that form two-dimensional and three-dimensional images.
Unlike mechanical engraving, which removes material from a surface, laser inner engraving creates the pattern within the transparent workpiece. This allows decorative images to be formed without cutting grooves into the outer surface.
Five models are available: SKLE-1218, SKLE-1325, SKLE-1530, SKLE-2030 and SKLE-2040. Maximum processing sizes range from 1200 × 1800 mm to 2000 × 4000 mm. The specified engraving speed is 180,000–480,000 dots per minute.

How Laser Inner Engraving Works
Laser inner engraving uses a focused laser beam to create small points within a transparent material. These points are arranged according to the programmed image to form visible decorative patterns.
The design is converted into a series of laser processing positions. As the machine follows the programmed pattern, individual points are formed at designated locations inside the workpiece.
By arranging these points at different positions and depths, the machine can produce both flat decorative patterns and three-dimensional internal images. The final appearance depends on the design, material and laser processing settings.
Laser Engraving Functions
2D Internal Pattern Engraving
The SKLE Series can produce lines, graphics and other two-dimensional patterns inside transparent glass or crystal. Laser points are positioned according to the prepared design.
3D Internal Image Engraving
Three-dimensional images can be formed by distributing laser points at different depths within the material. This method is suitable for decorative objects and customized internal image designs.
Computer-Controlled Engraving
The engraving process is controlled by a computer program. The machine follows the prepared processing pattern to position the laser points within the workpiece.
Internal Processing
The laser is focused inside the transparent material rather than mechanically grinding the external surface. The workpiece surface is not intentionally machined during the internal engraving process.
Adjustable Processing Conditions
The engraving program and laser processing settings are selected according to the required pattern, material and workpiece dimensions.
Typical Working Sequence
The engraving pattern is prepared before processing. After the transparent workpiece is positioned on the machine, the operator selects the required settings and starts the engraving program.
The machine follows the programmed positions to produce internal laser points. After engraving, the finished workpiece can be inspected for pattern appearance and completeness.

Technical Specifications
The SKLE Series consists of five models with different processing areas and machine weights. The listed models share the same laser wavelength, pulse specifications and engraving-speed range.
| Model | Max. Processing Size | Processing Speed | Machine Weight |
|---|---|---|---|
| SKLE-1218 | 1200 × 1800 mm | 180,000–480,000 dots/min | 1000 kg |
| SKLE-1325 | 1300 × 2500 mm | 180,000–480,000 dots/min | 1200 kg |
| SKLE-1530 | 1500 × 3000 mm | 180,000–480,000 dots/min | 1495 kg |
| SKLE-2030 | 2000 × 3000 mm | 180,000–480,000 dots/min | 2000 kg |
| SKLE-2040 | 2000 × 4000 mm | 180,000–480,000 dots/min | 2300 kg |
Common Laser Specifications
| Parameter | Specification |
|---|---|
| Minimum Processing Size | 3 × 3 mm |
| Laser Wavelength | 532 nm |
| Maximum Pulse Energy | 1.2 mJ |
| Pulse Width | 7 ns |
| Processing Method | Computer-Controlled Laser Inner Engraving |
The engraving speed refers to laser point processing. Actual completion time depends on pattern size, point density and material characteristics. Glass thickness capacity, electrical power and installation dimensions should be confirmed for the selected model.
Choosing the Right SKLE Model
The five SKLE models share the same published laser specifications. The main selection factor is the maximum processing area required for the glass or crystal workpiece.
SKLE-1218 and SKLE-1325
The SKLE-1218 supports workpieces up to 1200 × 1800 mm, while the SKLE-1325 extends the maximum processing size to 1300 × 2500 mm.
SKLE-1530
The SKLE-1530 accommodates processing sizes up to 1500 × 3000 mm. Its machine weight is 1495 kg.
SKLE-2030 and SKLE-2040
The SKLE-2030 supports processing sizes up to 2000 × 3000 mm. The SKLE-2040 provides the largest processing area in the series at 2000 × 4000 mm.
The appropriate model should be selected according to workpiece dimensions, material characteristics, engraving design and available installation space.
Applications
The SKLE Series is suitable for decorative engraving applications involving transparent glass and crystal.
Typical products include decorative glass panels, crystal artwork, personalized designs and glass products requiring internal two-dimensional or three-dimensional images.
Material suitability and engraving appearance should be evaluated according to the workpiece and required design.
Laser Inner Engraving vs. CNC Surface Engraving
Laser Inner Engraving
The SKLE Series produces decorative points inside transparent glass or crystal. It is intended for internal image creation rather than mechanical surface groove cutting.
CNC Surface Engraving
The SKE-CNC Series uses machining tools for decorative surface engraving and groove processing on flat glass.
For mechanical groove processing, see the CNC Glass Engraving Center .
Frequently Asked Questions
