Best Practices for Printing Dental Models with Resin

3D printing has revolutionized dental labs by enabling accurate, fast, and cost-effective model production. But achieving perfect results requires more than just high-quality resin—it requires the right workflow.

This guide shares best practices for printing dental models using resins like Senertek, ensuring precision and reliability.

1. Choose the Right Resin

Not all resins are suited for dental models. Look for materials with:

• Dimensional stability – Ensures accurate models

• Smooth surface finish – Easier to inspect and polish

• Low shrinkage – Maintains true size during curing

Senertek model resins are formulated to deliver consistent accuracy for all model applications.

2. Optimize Printer Settings

Printer settings directly affect quality. Recommended best practices:

• Layer height: 25–50 microns for high detail

• Exposure time: Follow resin manufacturer’s guidance

• Orientation: Minimize supports on critical surfaces to reduce artifacts

Testing small calibration prints helps find the perfect balance.

3. Proper Support Placement

Supports prevent warping and improve print success. Tips:

• Place supports away from key surfaces

• Ensure adequate support for overhangs

• Use minimal contact points to reduce post-processing

4. Post-Processing

Proper post-processing maintains accuracy and biocompatibility:

• Wash prints in isopropyl alcohol (IPA) or recommended solution

• Post-cure using UV light for the required duration

• Polish surfaces if necessary for smooth, accurate models

5. Storage & Handling

• Avoid prolonged UV exposure before use

• Store resins at recommended temperatures to maintain quality

• Label prints for patient-specific tracking

Conclusion

By following best practices, dental labs can maximize the performance of Senertek dental resins, reduce errors, and deliver high-quality models efficiently.
