Optimized for Mass Production.
Scaling an aligner business requires more than just clinical planning; it requires Production Efficiency. If your technicians are spending hours manually drawing cut lines or labeling models, you are losing money.
Our Design & Finish Service delivers files that are ready for the factory floor. We define the Trim Line (Cut Line) digitally within the software (3Shape/Maestro), ensuring your automated cutting machine knows exactly where to slice for patient comfort (Scalloped or Straight cut).
Technical Production Specs
We configure the files to match your manufacturing hardware (Printers & Cutters):
Trim Line Definition
- Gingival Margin: Precise curve definition (0.5mm – 1.0mm from margin) for Laser or CNC machines.
- Cut Style: Scalloped (following gumline) or Straight Cut (high trim).
- File Format: We export the specific curve metadata required by your machine (e.g., PTS file).
Model Engineering
- 3D Labeling: Patient Name + Step Number engraved/embossed on the base for sorting.
- Hollowing: Walls optimized (2.0mm) with drain holes to save resin and speed up printing.
- Base Design: Chamfered bases for easy removal from the build plate.
Why Outsource the “Finish”?
Clinical treatment planning is only half the battle. Preparing thousands of STL files for printing and cutting is the other half. China Dental Designs handles the tedious data preparation. We deliver a folder that goes straight to your Print Server and Cut Server.
Submission Workflow
- Scan: Upload Arches and Bite.
- Machine Specs: Tell us your Printer (e.g., SprintRay) and Cutter (e.g., Hamer, Laser).
- Receive: Download the Production Package (Models + Cut Files + Reports).
