Tough 2K Resin

Strong and tough applications

Tough 2K Resin is a tough and strong material with excellent ductility, toughness and impact resistance. As a result, it is ideally suitable for end-use parts where performance and durability are needed.

Tough 2K Resin exhibits strength and rigidity similar to ABS, and its excellent toughness and impact resistance make it suitable for a variety of performance prototyping and tooling applications, including strong and tough prototypes, end-use parts, jigs and fixtures, and manufacturing aids.

Printing Settings

It is recommended to use the default printing profiles available in ideaMaker.

After printing, it’s recommended to not leave a successful but unwashed model in the printer for too long. This will prevent the model from over-swelling, which may cause dimensional deviations or support softening.

For more printing information, please read Raise3D DF2 3D Printer User Manual.

Cleaning

Tough 2K Grey V1 Resin requires cleaning to achieve the ideal properties of the printed part.

There is no need to remove support structures from the printed part, and the part should then be washed before post-curing, until the surface is free of any solvent residue.

For special structures or fine details, such as small holes, it’s recommended to clean manually, and then blow dry the part with compressed air/nitrogen to remove residual solvent from the surface. Or leave the part for a short time at room temperature to dry. Post-cure the model until the surface is free of any solvent residue.

Please refer to the chart on the right for the recommended washing parameters with Raise3D DF Wash.

Post-curing

After cleaning, Tough 2K Grey V1 parts requires post-curing to achieve optimal properties. Please refer to the chart on the right for the parameters with Raise3D DF Cure.

Setting 1: For prototyping uses.

Setting 2: To achieve the best resin properties, as indicated in the TDS (default parameters in ideaMaker).
