ANYCUBIC Tough Resin Ultra is a photopolymer resin for 3D printing that stands out for its exceptional flexibility and high crack resistance. Thanks to an elongation at break of 70–80%, prints are strong, less brittle, and quickly return to their original shape after deformation. It is suitable for durable functional parts, moving parts, and models exposed to impacts or bending, while its formulation also reduces odor intensity during printing.
ANYCUBIC Tough Resin Ultra (black) was developed for users who need a combination of high-detail printing and higher mechanical strength. The resin handles thin-walled structures well, helps limit cracking under stress, and quickly returns to its original shape after bending. This makes it ideal for parts intended for frequent handling, transport, or long-term use.
The material also supports accurate reproduction of fine details (textures, small structural elements) and is suitable for models with moving parts that require easy adjustment or component replacement. The manufacturer also states a reduced impact of humidity and UV radiation on finished prints, which helps dimensional stability during storage.
Key benefits:
- High flexibility and impact resistance for functional prototypes and durable parts
- Elongation at break 70–80% – lower susceptibility to cracking
- High-detail printing suitable for fine structures and precise features
- Can be used on its own or as an additive to increase the toughness of other resins
- Wide compatibility with LCD/DLP printers using UV (typically 405 nm), optimized for Anycubic LCD printers
- Lower odor intensity for more comfortable everyday printing
