Notably, parts crafted using the Rock-Black Stiff resin boast an impressive thermal endurance, capable of withstanding temperatures of up to 97 ºC. These attributes collectively position this resin as an optimal choice for the additive manufacturing of reliable industrial prototypes and end-use parts.

The printing profiles for the Rock-Black Stiff resin can be found here.

Impact strength (KJ/m2) 3
Elongation at break (%) 4
Tensile strength (MPa) 30
Tensile modulus (MPa) 419
Surface hardness 8

Once opened, Phrozen Rock-Black Stiff resin must be stored properly to prevent degradation of the resin. To achieve the desired properties, parts 3D printed with Rock-Black Stiff resin must be post-processed. The parts must first be washed in IPA alcohol or any other authorized resin cleaning liquid and then post-cured under UV light. Washing and curing can be done with the help of devices such as the Phrozen Wash & Cure Kit or the Cure XL or Cure Mega curing devices.

More information on the maintenance of Rock-Black Stiff resin, as well as the printing and post-processing of 3D printed parts can be found in the Manual in the Downloads section.
