The BASF ST 45 B resin is a technical Resin that provides strength and robustness to printed parts. This Resin offers very high quality with a finish close to an injected part.

The ST45B formulation makes this Resin very precise, with an excellent look and surface quality. BASF ST 45 Black will elevate your prints from simple prototypes to finished technical and mechanical production parts.
Ideal for industry and highly valued by professionals, the Ultracur3D® ST45B Resin provides mechanical resistance when demanding and high-performance parts are required.
Its 5Kg packaging allows you to print without worrying about restocking while saving costs. Perfect for producing 3D resin parts requiring mechanical and UV resistance.
Professional look and finish: This ST Resin from the Ultracur3D range delivers results, appearance, and a finish close to high-quality injected parts.
Part durability: Objects printed with this technical resin are made to be durable and to withstand repeated and prolonged stress.
Dimensional accuracy: The ST45B urethane resin provides high-quality dimensional precision for parts with minimal deformation.
Mechanical resistance: BASF ST 45 B Resin is specifically developed for high mechanical resistance to shocks and impacts.
Be sure to shake the resin before pouring it into your 3D printer’s vat. It must be protected from UV light as much as possible, so we recommend always taking the necessary precautions.
The exposure time of this technical urethane resin is usually longer than standard resins. We recommend performing a few tests to find the best settings for your equipment.
After printing, you will need to use a suitable cleaning solution (such as IPA or Cleaner) to clean your 3D prints and remove resin residues. A UV curing step is also required to achieve all the technical properties of this high-performance resin.
