## Description

A premium, optical-grade glass blank specifically engineered for sub-surface laser engraving. Unlike standard glass that is etched on the surface, this crystal allows for internal 3D engraving (bubblegrams), where a high-precision laser creates intricate 3D designs suspended inside the solid material while leaving the exterior faces perfectly smooth to the touch.

Achieving clean, 3D internal results requires a material free from microscopic inclusions and structural inconsistencies that can cause fractures or "shattering" during processing. This crystal blank solves that by providing a uniform molecular structure, ensuring your designs remain crisp, sharp, and perfectly "floating" inside the medium.

Manufactured from high-purity K9 glass, this 50 x 50 x 80mm prism is an official xTool accessory, ensuring perfect compatibility with the F2 Ultra UV laser system. The inclusion of an integrated QR code for one-click parameter setup means you can skip the guesswork and move straight to making!

### Features

- **Produce professional 3D "bubblegrams"** thanks to the high-clarity K9 composition.
- **Streamline your workflow** with the integrated Material QR Code, allowing for instant parameter configuration in xTool Creative Space (XCS) to achieve optimal contrast every time.
- **Capture and refract light brilliantly** across your designs, as the K9 optical-grade glass offers a superior refractive index compared to standard soda-lime glass.
- **Create high-value commemorative items** such as bespoke trophies, architectural models, or personalised keepsakes with a substantial 50mm thickness that provides depth for complex 3D scenes.
