Ultra Tough Resin 3D Printer Resin (Black, 1kg) - Flexible Impact

In this review the ANYCUBIC Ultra Tough Resin (Black, 1kg) is evaluated for modelers and hobbyists who need durability with flexibility. The bottom line: this resin is best for prints that require impact resistance and repeated motion, such as articulated figures, wearable pieces, and functional parts; it recovers shape well after deformation and reduces breakage compared with brittle resins. The reviewer found print quality comparable to standard resins while delivering noticeably better toughness and a gentle skin feel after curing.

Key Features

• Impact resistance: The resin returns quickly to its original shape after forceful deformation, which reduces the risk of cracking under stress.
• Exceptional flexibility: Its high elasticity makes it suitable for parts that must bend or flex repeatedly without failing.
• Articulated model precision: Fine hair-like textures and narrow joints print sharply, improving fit and movement for multi-part figures.
• Wearable comfort: After curing the surface is reported to be non-irritating and pleasant to touch, useful for earphone covers and costume pieces.
• Blendable additive: It works straight from the bottle or as an additive to toughen other resins, enhancing durability when mixed.
• Environmental resilience: The material resists brittleness, softening, and corrosion even in humid conditions, keeping parts functional in varied environments.

Who It's For

The resin is aimed at hobbyists and small-scale manufacturers who need parts that survive handling and light impacts, for example tabletop miniatures with moving joints, prototypes with snap-fit connectors, and wearable props that contact skin. Users who value a less brittle finished part and improved interchangeability of small components will find this resin particularly useful.

Those who should look elsewhere include modelers seeking ultra-fine, brittle-detail casts without any flexibility or users who require a very thin, low-viscosity resin for extreme micro-detail; several customers noted the resin can be thicker than standard formulations, which may affect flow in some printers or delicate supports.

Pros & Cons

Pros

• Strong durability and impact resistance reduce failed parts from drops or repeated motion.
• Good flexibility and elasticity make it suitable for articulated models and wearable pieces.
• Print quality and detail are comparable to standard resins, with improved texture clarity for hair-like features.
• Works as an additive to toughen other resins without losing primary mechanical benefits.

Cons

• The resin's viscosity can be higher than some standard resins, which a few customers found thick for certain printers or thin features.
• Mixing different colors may change final tone, so color matching requires care when blending.

Our Verdict

The ANYCUBIC Ultra Tough Resin is a sensible choice for anyone needing tougher, flexible prints that still hold fine detail. It offers good value where durability and wearability matter, particularly for articulated figures and wearable printed parts, though users should account for its slightly thicker feel when planning supports and fine features.

Frequently Asked Questions

Can this resin be mixed with other resins?
Yes. It is formulated to be used directly or blended as an additive to increase toughness, but mixing colors may alter the final shade.

Is it safe to wear on skin after curing?
After proper curing the surface is described as non-irritating and comfortable for wearable pieces, though standard post-processing and curing procedures should be followed.

Will it print fine details like hair and small joints?
Yes. The resin improves clarity and sharpness for hair-like textures and is well suited to articulated joints that require smooth movement.
