Harz Labs Industrial Rigid 3D Printing Resin


Designed for printing hard models and prototypes. It is an accurate and low-shrinkage material can be used for printing miniatures and decorative items.



3D printing resin Harz Labs Industrial Rigid Black has high hardness and bending strength. It has increased resistance to aggressive environments. Allows you to print functional models, such as fittings, adapters, parts of washing equipment, as well as rigid prototypes. The weakly expressed smell and the absence of volatile monomers allows the material to be used even in small workshops.


Russian certification. Product without european certification, to be used only for models.

3D printing resin Harz Labs Industrial Rigid characteristics


 Appearance   Colored liquid
 Color   Black
 Elongation at break          17 ± 3 %
 Hardness (Shore D)   86 ± 3
 Odor   Weak
 Tensile strength   75 ± 5 MPa
 Viscosity (Brookfield) at 25°C 700 ± 250 mPa*s
 Tensile modulus of elasticity   970 ± 100 MPa





    Resin is stable to solvents, aggressive inorganic media like acids and alkalis.


    Resins are odorless and cause no irritation, so you can work with natural ventilation.


    Shrinkage less than 0.5% gives you the same size of the 3D model on your computer.


    The resin has Heat Deflection Temperature (HDT) equals to 90°C at a load of 0.45 MPa. 


    Resin is very stable. You can leave it for long time in the vat, no sedimentation and gel formation occur – no need to mix.


    Very high hardness and tensile strength.

Finishing Instructions


  1. To clean and remove excess resin, flash the 3D printed part for 30 seconds, several times until excess resin is removed, in an ultrasonic cleaner with TEK1960* .

  2. Do not soak in acetone. Do not leave the 3D part soaking in the liquid. Use a soft brush if necessary.

  3. Clean off any excess of liquid with a cold blowdryer or compressed air.

  4. Leave under the sun or in a UV lamp to cure. The resin is fully cured when fingernails do not leave scratch marks on the object.

*We do not recommend the use of denatured or isopropyl alcohol (IPA). It is very aggressive on the polymerized resin and it could weaken the structure of the 3D part. It is also flammable and potentially harmful to people and the environment.

Store the resin in a dry, cool, shaded place out of direct sunlight.
