Part detached from the build plate during printing

Q: What is the first cause to check when a part detaches from the build plate?

The first cause to check is poor platform leveling. Redo the leveling according to the printer manual, calibrating the distance between the platform and the FEP with A4 paper.

Q: What is the recommended exposure time for the initial layers (bottom layers) with Smart Dent resins?

For Smart Dent resins, between 30 and 50 seconds of exposure for the first 5 layers is recommended to improve part adhesion to the platform.

Q: How can the condition of the FEP affect part adhesion during printing?

A FEP with scratches or resin residue from a previous cure interferes negatively with adhesion. The solution is to clean with IPA 90%+ or replace the FEP.

Q: What to do when the part has insufficient support base and detaches easily?

Use CAD software to add more supports to the part, especially on thin edges, ensuring greater stability during printing.

Q: Why is resin homogenization important to prevent the part from detaching from the platform?

Poorly homogenized resin can compromise adhesion. Therefore, the resin should be stirred before use to ensure its correct consistency and cure properties.

Loss of adhesion is one of the most frustrating errors in dental 3D printing. It usually has a simple solution.

Diagnosis Checklist

1. Build plate leveling

The primary cause is poor leveling. Re-level the build plate according to your printer's manual. The correct distance between the build plate and the FEP should be calibrated with A4 paper.

2. Exposure time of initial layers (bottom layers)

Increase the exposure time of the first layers (bottom exposure) to improve adhesion. For Smart Dent resins, we recommend between 30-50 seconds for the first 5 layers.

3. Dirty or scratched FEP

A FEP with scratches or residue from previous resin curing interferes with adhesion. Clean with 90%+ IPA alcohol or replace the FEP.

4. Insufficient supports

Parts with little support base easily detach. Use CAD software to add more supports, especially on thin edges.

5. Poorly homogenized resin

The resin should be shaken for 2-3 minutes before use. Heavy pigments and photoinitiators settle over time.
