What is the difference between the Anycubic Tough V2 and the Anycubic Tough Ultra?

What is the difference between anycubic tough v2 and anycubic tough ultra

Tough V2 is a stiffer and more universal resin focused on strength and accuracy. Tough Ultra is a more flexible and impact resistant modification with better recovery after deformation. Both are compatible with UV 365 to 405 nm and suitable for most LCD DLP 3D printers.

Comparison table

Parameter Tough V2 Tough Ultra
Material type Rigid and strong tough resin with good accuracy More elastic and impact resistant tough resin
Recommended applications Fixed structures, housings, functional prototypes with minimal deformation Parts working under bending and impact, latches, clips, shock resistant covers
Elasticity and elongation at break Medium to high, suitable for moderate deformations Higher elasticity, better withstands strong bends
Stiffness and modulus Higher stiffness and modulus, stable geometry Lower stiffness in favor of better flexibility
Impact resistance Good, cracks possible under strong impact Very good, absorbs shocks and recovers shape
Viscosity Lower, easier polymerization and vat flow Higher, requires slightly longer exposures
Fine detail accuracy High accuracy and sharp edges High, but surface may feel softer
Brittleness tendency Lower than standard resins, still stiffer than Ultra Lowest brittleness of the pair, softer behavior
Wavelength range 365 to 405 nm 365 to 405 nm
Recommended scenarios Functional parts where stiffness and accuracy matter Parts where impact resistance and flexibility are important

Practical tips for choosing

  • Choose Tough V2 if you need stiffness accuracy and shape stability
  • Choose Tough Ultra if you need impact resistance and bendability without sudden cracks
  • When switching from V2 to Ultra increase exposure times and allow more drainage pause between lifts
  • Color affects exposures darker and translucent resins may need different values

FAQ

Are both resins compatible with the same printers Yes if the printer operates in 365 to 405 nm range
Can Tough V2 and Tough Ultra be mixed Not recommended for production use due to unpredictable properties of a mix
Are they suitable for functional parts Yes V2 is better for rigid parts Ultra is better for parts under impact or bending
