Anycubic Tough Resin Ultra

Engineered Toughness for Demanding 3D Prints

Anycubic Tough Resin Ultra is built for creators who need more than just visual perfection. This high-strength photopolymer resin delivers exceptional impact resistance and outstanding rebound, allowing printed parts to withstand stress, pressure, and repeated handling without cracking or deforming.

With a hardness of 71–75 HD, tensile strength of 20–28 MPa, and elongation at break of 70–80%, this tough 3D printer resin offers the perfect balance between rigidity and flexibility. It resists brittleness, corrosion, and softening—even in high-humidity environments—making it ideal for functional prototypes, engineering components, and mechanical assemblies.

Optimized for 365–405 nm UV LCD and MSLA 3D printers, it provides stable curing performance and reliable layer adhesion. The controlled viscosity of 500–900 mPa·s (25°C) ensures smooth resin flow and consistent print quality, while a low volume shrinkage rate of 5.1–6.2% supports dimensional accuracy for precision parts.

When durability is non-negotiable, Tough Resin Ultra delivers confidence in every layer.

Flexible Performance with Fine Detail Precision

This flexible 3D printing resin enhances surface clarity and preserves intricate textures, making it perfect for detailed models and articulated designs. The ultra color highlights contours and fine features such as hair strands, small engravings, and complex geometries.

Ideal applications include:

• Miniatures and collectible figurines

• Articulated models and moving joints

• Wearable accessories and cosplay parts

• Earphone covers and skin-contact components

After curing under 405 nm UV light, the resin provides a smooth, refined finish with enhanced elasticity. Its flexibility allows parts to bend under stress and return to shape, reducing breakage during assembly or use. The improved rebound performance supports snap-fit structures and interchangeable components.

This high-detail tough resin combines strength with adaptability, enabling both aesthetic excellence and functional reliability.

Optimized Printing Parameters for Professional Results

Anycubic Tough Resin Ultra integrates seamlessly into professional workflows, offering predictable exposure times and efficient post-processing.
