Create precise 3D internal engravings with this pristine block of K9 Crystal. This high-purity optical glass blank features a material QR code for reliable parameter setup and is engineered specifically for sub-surface processing with UV laser systems.

## Pricing

- **Price:** $27.40 (inc GST) — $24.91 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 47 today, and up to 300 more in 22–23 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10534:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE10534:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## 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.
