Parts 3D printed with Grey Resin

Why Choose Grey Resin?

Grey Resin V5 is a versatile 3D printing resin formulated to leverage the new Form 4 ecosystem, offering an optimal balance of fast print speed, high accuracy, presentation-ready appearance, strong mechanical properties, and an easy, reliable workflow.

Highest Dimensional Accuracy

Achieve precise tolerances with xy dimensional tolerances of ±0.15% (lower limit: ±0.02 mm)

Superior Aesthetics

Rival the appearance of injection-molded parts with rich, matte color and crisp fine feature performance.

Versatile Mechanical Properties

Create parts with the optimal balance of strength, toughness, and stiffness for a wide range of applications.

Extremely Low-Odor Printing

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

Applications for Grey Resin

Create dimensionally accurate parts that are stiff and strong with unmatched print reliability.

Consider Grey Resin for:

Form and fit prototyping
Presentation-ready models with fine features and intricate details
General dental models
Jigs and fixtures
3D printed in Grey Resin

Post-curing is optional for parts printed in Grey Resin V5. 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.
