The ComMarker Omni X/XE UV laser engravers have become popular for their new 3D glass engraving capabilities, especially the 3D glass internal engraving feature. As the demand for this unique feature grows, many users are exploring the possibilities of engraving inside K9 crystal cubes to create stunning 3D designs. However, some users have encountered issues when trying to perform 3D glass engraving on crystals purchased from third-party sources. The reason? Not all glass pieces are suitable for 3D engraving.
Why Only K9 Crystal Works for 3D Glass Engraving
ComMarker’s 3D glass engraving function is designed specifically for K9 crystal cubes. If you’re using a non-K9 crystal, it simply won’t work correctly, and the results may not meet expectations. The key issue here lies in the material properties of the glass.
Here’s how to distinguish real K9 crystals from fake ones and ensure you’re using the correct material for your laser engraver:
How to Identify Real K9 Crystal:
Blue Light Test:
-
-
When you place a genuine K9 crystal cube under the preview light of the ComMarker Omni X/XE, you’ll notice that no blue light passes through the crystal.
-
Fake K9 crystals, on the other hand, will allow blue light to pass through, indicating they are not of the same material quality.

Why K9 Crystal Works for 3D Glass Engraving:
K9 crystal, also known as optical crystal, has properties that make it suitable for UV laser engraving. When it comes to the ComMarker Omni X/XE, the crystal’s smooth surface and the way it reacts to UV light allow for the high precision required to carve intricate designs inside the material. Other glass types, especially cheaper or imitation crystals, lack these properties and don’t allow for the same detailed engraving.
Conclusion:
When working with 3D glass engraving on the ComMarker Omni X/XE, using the correct K9 crystal cube is essential for achieving the best results. The simple blue light test is an effective way to differentiate between real and fake crystals, ensuring that your projects are as flawless as possible.
By making sure you use authentic K9 crystals, adjusting your settings correctly, and selecting the proper STL or OBJ files, you can unlock the full potential of the 3D glass engraving feature on your ComMarker Omni X/XE UV laser engraver.
