The Industrial Rigid Black resin is a high-performance 3D printing resin from the portfolio of Harz Labs. Known for its exceptional chemical resistance, rigidity, and hardness, this resin was initially developed for fertilizer mixers, and has since found many applications such as lighting devices, PCB washing systems, conveyor line mounts requiring sterilization, as well as componentes of car camera washers. The resin is ideal for creating 3D-printed fittings, adapters, washing equipment components, and complex geometric models, serving both functional prototypes and finished products in demanding industrial applications.

Key features of this resin include low shrinkage (less than 0.5 %) and excellent dimensional accuracy, ensuring that printed models retain the exact size as designed in digital form and remain unchanged after post-curing. The resin is highly stable, with no sedimentation or gel formation occurring in the vat, eliminating the need for mixing. Additionally, it is odorless, causes no irritation, and contains no volatile monomers, making it safe for use with natural ventilation even in small workshops.

The Industrial Rigid Black resin exhibits impressive mechanical and thermal properties, including a high hardness level of Shore D 86 ± 3 and tensile strength of 75 ± 5 MPa. The material also boasts significant elongation at break of 17 ± 3% and a tensile modulus of elasticity of 970 ± 100 MPa. With a Heat Deflection Temperature (HDT) of 90 ºC at a load of 0.45 MPa, this resin is well-suited for high-temperature applications. It maintains stability when exposed to solvents and aggressive inorganic media such as acids and alkalis (see image below), making it an ideal choice for harsh industrial environments.

The print settings for the Industrial Rigid Black resin can be found on the manufacturer's website. Once the printing has been completed, the part must be removed from the manufacturing platform with a metal spatula, taking care not to damage the surface of the platform. The part should then be washed twice (3 minutes each time) in IPA alcohol to remove the uncured resin from the outer walls of the part. After this time, air pressure should be applied to the piece until it is completely dry. To achieve the maximum properties that HARZ Industrial Rigid Black can provide, it is necessary to cure the part in a curing station (Form Cure) for 30 minutes. Washing and curing parameters can be found on the Harz Labs website.

Before removing the parts from the manufacturing base, the user must be equipped with a series of safety measures. The use of gloves is recommended to prevent resin and alcohol from contacting the skin. It is also crucial to wear safety glasses for any drops that may arise during the washing of the parts.
