😁 Dental Aligners Made with 3D Printing
Gone are the days of metal braces. In 2025, custom dental aligners made using 3D printing are not just more popular — they’re more affordable, faster, and made with precision-fit technology.
This blog explains how aligners are 3D printed, why dentists and startups prefer them, and how this market is booming in India and globally.
🦷 What Are 3D Printed Dental Aligners?
Dental aligners are transparent, removable trays that gradually move teeth into the desired position.
With 3D printing, each aligner is custom-designed and made from a digitally scanned model of the patient’s mouth.
Instead of manual impressions and molds, everything is done digitally + additively.
🖨️ How the Process Works
- 🧑⚕️ Intraoral Scan: A 3D digital scan is taken of the patient’s teeth
- 💻 Treatment Planning: Software simulates gradual teeth movement
- 🖨️ Model Printing: Each stage is printed using resin or FDM printers
- ♻️ Thermoforming: Clear aligners are molded on the printed models
- 🧼 Finishing & Polishing: Aligners are trimmed, cleaned, and packaged
Each patient may require 10–40 aligners, depending on the treatment plan.
💡 Why 3D Printing Is Ideal for Aligners
- ✅ Accurate fit with no manual errors
- ✅ Faster turnaround (2–5 days)
- ✅ Cost-effective for labs and startups
- ✅ Scalable for bulk production
- ✅ Easy to customize and remake if needed
