When it comes to 3D printing aligner models, the key considerations are precision, durability, and speed. Whether you’re creating models for custom clear aligners or other orthodontic applications, choosing the right resin is one of the most important decisions affecting print quality and efficiency.
Two of the top contenders in the market today are Phrozen Aqua-Gray 4K Resin and Anycubic Standard UV Resin — both offering unique advantages that make them ideal for aligner production.
Why the Right Resin Matters for Aligner Models
The resin used in 3D printing directly impacts the clarity, precision, and durability of the final model. Orthodontic models require fine detail, sharp edges, and long-lasting stability to ensure a perfect fit for aligners — ultimately ensuring patient comfort and treatment accuracy.
Key Reasons Resin Quality Is Crucial
1. Resolution
High-resolution resins ensure that even the smallest details — like tooth contours and micro-adjustments — are printed accurately.
2. Durability
A strong, fracture-resistant resin ensures that the printed models withstand the pressure and heat of aligner molding without breaking or deforming.
3. Printing Ease
Resins with smooth flow and fast, consistent curing reduce printing errors and improve production speed, saving time and materials.
