Robot laser cutting machine for aligners

Machine Description

This patented aligner trimming cell is designed for the fully automated, high-precision trimming of orthodontic aligners made from polyurethane and other dental elastomers.

The system combines laser-based cutting technology with a 6-axis industrial robot, enabling unit-of-one production with infinite geometric versatility at industrial throughput rates.

Each aligner is processed individually based on patient-specific 3D data. Automated 3D path planning ensures precise, repeatable trimming of complex and delicate contours without mechanical contact.

- Consistent cutting quality independent of tool wear
- High contour accuracy for complex geometries
- Reduced scrap and rework
- Stable processes at high production speeds

Special attention has been given to robot dynamics, vibration control, and process stability, enabling damage-free trimming despite the lower stiffness of 6-axis robots compared to classical CNC machines.

Applications
- Orthodontic aligner production
- Digital dental manufacturing
- Automated medical device production
- High-variance, unit-of-one manufacturing environments

Integration & Automation
The trimming cell is designed for straightforward integration into fully automated aligner production lines, including upstream thermoforming and downstream handling or inspection systems.
