Anycubic Tough Resin Ultra Grey — Flexible, Impact-Resistant & Skin-Friendly Resin
Anycubic Tough Resin Ultra Grey is a next-generation photopolymer designed for functional, wearable, and mechanical parts that require both high durability and a soft touch. With outstanding toughness, elasticity, and rebound recovery, it’s perfect for printing models that experience frequent stress or flexing — such as earphone covers, joints, and cosplay accessories. It can also be blended with other resins to enhance their toughness.
Key Advantages
- Excellent Flexibility: Elongation at break up to 80% with quick rebound after deformation.
- Impact Resistance: Resilient under stress with long-term durability in damp or humid environments.
- Versatile Application: Can be used alone or blended with other resins to improve toughness.
- Skin-Safe and Soft: Gentle texture after curing, ideal for wearable models and skin-contact applications.
- Stable in Harsh Conditions: Maintains flexibility even in high humidity and varying temperatures.

Instructions for Use
- Before use: Shake the bottle well. Clean the resin tank and ensure optical clarity.
- During use: Pour resin into tank and set parameters according to your printer's requirements.
- After printing: Remove model carefully with tools and rinse in ≥95% isopropyl alcohol or lactate-based cleaner. Use ultrasonic cleaning for best results.
- Post-processing: Remove supports, polish if necessary, and perform UV curing under light source or with Anycubic Wash & Cure machine.
Precautions
- Store unused resin in a cool, dark place (18–35°C) away from sunlight and high temperatures.
- If thickened in cold environments, preheat resin slightly (not above 60°C) before use.
- Stir or shake if pigment settles over time.
- Do not leave prints soaking in alcohol or water for extended periods.
- Always perform UV post-curing after cleaning to retain mechanical strength.
- Print in a dark room or cover the printer to prevent light-induced polymerization during printing.
Frequently Asked Questions (FAQ)
