Phrozen Functional Resin Tough ABS-Like+ Gray High Toughness 1KG Review (2026)

What this resin is

This is Phrozen's Functional Resin in the Tough ABS-Like+ formula, sold in gray and in a 1kg bottle, cured under 405nm DLP or LCD UV light. Phrozen distributor filament2print lists mechanical figures for the formula including a tensile strength of 35.8 MPa, elongation at break of 17.7 percent, flexural strength of 80 MPa, and a Shore hardness around 75 to 80D, along with a heat deflection temperature of about 57 degrees Celsius. Those numbers describe a resin built to survive bending and moderate impact while keeping enough stiffness to behave like an engineering plastic rather than a purely display oriented material, positioning it above Phrozen's standard resin lines for functional use.

Toughness in practice

The combination of moderate elongation with meaningfully higher tensile and flexural strength than a typical display resin is what earns this line the ABS-Like+ name, since it targets some of the impact resistance associated with ABS plastic while remaining a UV curable resin rather than a filament. That makes it a reasonable fit for prototypes, scale model components, and parts in industrial or action figure applications that need to survive being handled, assembled, and occasionally dropped without snapping. It will not match the outright flexibility of a rubber-like flexible resin, since the elongation figure here is closer to a stiff engineering plastic than a bendable one.

Post processing requirements

According to filament2print, parts printed with this resin need washing in isopropyl alcohol followed by a UV curing step to reach their full published mechanical properties, so the toughness figures reflect a fully post processed part rather than one straight off the build plate. That is a heavier post processing routine than a water washable resin, and skipping or shortening the UV cure step is likely to leave parts weaker and less impact resistant than the specification sheet suggests. Buyers used to a simpler washable resin workflow should budget the extra time for a proper alcohol wash and cure cycle to get the durability this resin is sold on.

Print settings and cost

Phrozen sells this resin at a price point above the brand's standard resin lines, consistent with its positioning as a functional, engineering oriented formula rather than an everyday hobby resin. Specialty tough resins like this one typically need their own tuned exposure and lift settings rather than reusing a standard resin profile, since the different formulation and higher viscosity than a basic resin can behave differently during printing. It is also sold in a larger 5kg option alongside the 1kg bottle, which suits workshops or small businesses using enough of this resin regularly to benefit from a lower per gram cost at volume.

Who should buy it

This resin fits makers and small scale engineers who need parts with genuine impact resistance and structural rigidity, such as functional prototypes, jigs, or action figure components, rather than static display miniatures. The published mechanical data gives more confidence in its toughness claims than resins that only describe themselves qualitatively as tough, which is a useful point of comparison when shopping this category. It is a premium priced resin best suited to buyers who need that documented durability and are willing to follow a full alcohol wash and UV cure routine, rather than casual users who mainly want an easy cleanup resin for display prints.
