"Open vs. closed" is not about the material — it is about who controls your workflow after you buy the disc.
Open materials
An open disc works on any mill, exports to any CAD, and is priced by the market. You are never hostage to one vendor's puck.
Closed materials
Brand-locked blanks may need proprietary holders or firmware; convenient, but a discontinued puck can strand your machine. The "discount" is paid back as lock-in.
The real test
- Can the disc run on a second mill? If yes, it is open.
- Does the file export without a watermark or paywall? If yes, it is open.
Every zirconia, PMMA, and PEEK disc we sell is open-system and mill-agnostic.

De-risk a closed buy
- Ask the discontinuation policy in writing.
- Keep one open mill as exit.
- Archive native files, not just STL, so you can re-cut elsewhere.
