3D printed parts in Fast Model Resin

Why Choose Fast Model Resin?

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

Parts As Fast As You Can Design Them

Print a fully packed build on Form 4 in 2 hours.

Fast Post-Processing

Post-process parts quickly with a 5-minute wash and 5-minute room temperature post-cure.

Presentation-Ready Appearance

Create parts with a matte grey color and smooth surface finish.

Extremely Low-Odor Printing

Print with ultra-low volatile organic compounds (VOCs) for a pleasant and comfortable user experience.

Applications for Fast Model Resin

Fast Model Resin is capable of 3D printing a full Form 4 build volume in under two hours, making it ideal for rapid prototyping and high-throughput applications.

Consider Fast Model Resin for:

Initial prototypes for shape and feel
Rapid design iterations
Large models that can print quickly
Dental models for thermoforming aligners
Parts 3D printed with Fast Model Resin

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
Stronger and stiffer — 45% higher strength and modulus
More opaque and matte in color

Wash Settings


5 minutes


Start with a 5-minute wash and modify the wash time based on your part geometry and solvent purity.

Form Cure Settings


5 minutes at room temperature


15 minutes at 60 °C


Post-curing is optional for parts printed in Fast Model Resin. However, we recommend either a 5-minute room temperature cure to reduce surface tack and improve mechanical properties, or a 15-minute cure at 60 °C for the highest strength, stiffness, and heat deflection temperature.
