Liberate Your Primescan Data. Unlock Open Workflows.
Receiving digital impressions from a Primescan or Omnicam is great, but the proprietary file format often locks your laboratory into the closed Sirona ecosystem. If you want to design natively in Exocad, print models on a Formlabs or SprintRay, or utilize third-party milling centers, you strictly need open STL/PLY files. China Dental Design provides a highly efficient, legal, and seamless CEREC to STL Conversion Service to liberate your digital data instantly.
Technical Processing Capabilities
We utilize fully licensed software infrastructure to legally receive, process, and export your proprietary files with 100% geometric accuracy and zero data loss:
Supported File Formats
- Sirona Connect Center: Cases sent directly through the Dentsply Sirona Connect portal.
- Proprietary Exports: Raw .dxd (Diagnosis), .rst (Restoration), .cmg, and .3si files.
- Legacy Systems: Older Bluecam and Redcam file versions.
Open Output Options
- STL (Standard): High-resolution, monochrome geometry mesh. Perfect for immediate 3D printing or Exocad design.
- PLY (Color Texture): Contains both precision geometry and true-color texture. Absolutely essential for your CAD designers to identify finish lines and soft tissue clearly.
- Mesh Clean-up: Optional watertight mesh repair (hole filling) included at no extra charge to ensure printability.
Two 100% Secure B2B Workflows
Method A: Sirona Connect Portal (Highly Recommended)
- Log in to your clinician’s or lab’s Sirona Connect Case Center account.
- Search for our verified portal ID: direct@chinadentaldesign.net and add us as your favorite Partner Lab.
- Send the case directly through the portal. We receive the raw data, convert it, and securely upload the open STL/PLY to your dashboard.
Method B: Secure Portal Transfer (For .DXD Files)
- Export the case manually as a “.dxd” file directly from your CEREC acquisition unit.
- Upload the file exclusively via our 100% HIPAA-compliant secure portal (Do not use unsecured platforms like WeTransfer for patient files).
- We execute the CEREC to STL Conversion Service and return the open files overnight.

Frequently Asked Questions
- Is this conversion process legal?
Absolutely. We hold valid, paid enterprise software licenses that legally allow us to act as a partner lab to receive, process, and export Sirona cases. You are simply outsourcing the digital model generation step to our facility. - Why do I need PLY instead of just STL?
If your in-house technicians are digitally ditching dies or drawing margin lines, the high-definition color texture embedded in PLY files helps them distinguish the prep finish line from the bleeding gingiva significantly better than a flat, monochrome STL file.
