Why Choose Fast Model Resin?
Fast Model Resin is Formlabs’ fastest dental 3D printing resin, capable of printing at speeds of 100 mm per hour.

Print a Model a Minute
Print 11 arches in one job in just 9 minutes.
Fast Post-Processing
Post-process parts quickly with a 5-minute wash and 5-minute room temperature post-cure.
Unmatched Reliability
Print confidently with an end-to-end product ecosystem rigorously validated for continuous uptime and reliability.
Accurate Orthodontic Models
Consistently create orthodontic models with 95% of printed surface area within 100 μm of the digital model.
What’s New With Fast Model Resin?
Fast Model Resin is the next generation of Draft Resin, formulated to leverage the new Form 4 ecosystem.

Compared to Draft Resin V2, Fast Model Resin is:
- Faster — formulated to take advantage of the new Form 4 ecosystem to print three times faster
-
More opaque and matte in color
-
Stronger and stiffer — 45% higher strength and modulus
Post-Processing
Wash Settings
Duration
5 minutes
Notes
Start with a 5-minute wash and modify the wash time based on your part geometry and solvent purity.
Cure Settings
Default
5 minutes at room temperature
Enhanced
15 minutes at 60 °C
Notes
Fast Model Resin can either be used with either a 5-minute room temperature cure for faster turnarounds or with a 15-minute cure at 60 °C for improved strength, stiffness, and heat deflection temperature.
