ANYCUBIC Ultra Tough Resin Strong Impact Resistance High Flexibility White 1kg Review (2026)

What this resin is

This is ANYCUBIC's Ultra Tough Resin, sold in a white 1kg bottle and built around strong impact resistance combined with high flexibility. ANYCUBIC's own specifications for this resin line list elongation at break in the range of 70 to 80 percent, tensile strength around 20 to 28 MPa, and a Shore hardness of roughly 71 to 75D, figures that describe a resin meant to flex and absorb stress rather than stay rigid under load. It is rated for 365 to 405nm wavelength LCD and DLP printers, which covers the light sources used by most current resin printers, including ANYCUBIC's own Photon series and comparable machines from other brands.

Flexibility and impact resistance

The elongation figures ANYCUBIC publishes for this resin describe a material that can stretch significantly before breaking, which in practice means thin walled parts, hinges, and snap fit features are far less likely to snap under normal handling than they would in a standard rigid resin. ANYCUBIC also says the formula is engineered to resist moisture intrusion and UV related degradation over time, aimed at keeping flexible parts from becoming brittle or misshapen after weeks of use rather than only performing well right off the build plate. That combination targets functional prints like cable ties, joint balls, and other parts meant to be handled and flexed repeatedly rather than sit on a shelf.

Odor and print behavior

ANYCUBIC describes this resin as basically odorless, which is a practical benefit for anyone printing indoors without dedicated workshop ventilation. Flexible resins in general tend to need more careful print settings than rigid resin, since thin, elastic features can be more prone to warping or peeling off the build plate mid print if exposure and lift settings are not tuned for the formula. ANYCUBIC notes the resin can also be blended with other resins to increase impact resistance rather than used purely on its own, which gives some flexibility in dialing in a stiffness and durability balance for a specific print rather than being locked into one fixed hardness.

Color and finish

The white color is a practical middle ground for a functional resin, since it shows surface defects and layer lines more clearly than a black resin while also serving as a neutral base if a part will be painted after printing. ANYCUBIC's listing for this resin is also available in gray, black, and clear versions, so the white bottle mainly comes down to aesthetic preference for prototypes or parts that will not be hidden inside an enclosure. Fine detail like hair textures on figures is mentioned in ANYCUBIC's own marketing for the line, suggesting the resin is tuned to hold detail despite its flexible mechanical properties.

Who should buy it

This resin fits makers who need parts that survive bending, repeated handling, or occasional drops, such as cable ties, hinge components, or snap fit enclosures, rather than rigid mechanical parts with tight tolerances. It is not the top rated tough resin in its category based on the site's own scoring, so buyers focused purely on maximum toughness may want to compare it against higher ranked alternatives before ordering. Anyone needing stiff, dimensionally precise parts for fittings or jigs will likely get better results from a rigid engineering resin rather than this flexibility focused formula.
