Raise3D Tough 2K: ABS-Like Tough Resin for Functional Parts (1 kg)
Tough 2K is Raise3D's resin for parts that actually work, assemble, and take a hit. Raise3D describes it as having strength and stiffness similar to ABS, with good ductility. The numbers back it up: 45 MPa tensile strength, 35% elongation at break, and a 2158 MPa modulus. You'll see it used in enclosures, tooling, manufacturing aids, and prototypes that need to hold up to real-world use.
Key Specs
- ABS-like mechanical behavior per Raise3D.
- 35% elongation at break (post-cured); 59% in green state.
- 45 MPa tensile strength and 2158 MPa Young's modulus.
- 31 J/m notched Izod impact strength.
- HDT of 68 °C at 0.45 MPa.
- Gray color (PMS 7543 C / RAL 7040), Shore 87D hardness.
- 1 kg cartridge for the DF2 and DF2+.
What Parts Is It Good For?
Enclosures and snap-fit boxes, screw-mounted parts, guides, and tooling that someone is going to handle every day. That 35% elongation is what sets it apart — the part warns you before it breaks. Raise3D even illustrates it in their datasheet with an FPGA enclosure, which is exactly that kind of use case.
Tough 2K or Rigid 3K?
If the part needs to flex or absorb impact, go with Tough 2K. If it needs to be stiffer or handle higher temperatures, Rigid 3K is the better choice (97 °C HDT vs. 68 °C).
Does It Work on Printers Other Than the DF2?
Raise3D only offers this resin for their DLP ecosystem — the DF2 and the DF2+. It comes in the 1 kg cartridge that feeds directly into these machines' automatic resin system, and the DF2 verifies the resin type via RFID to apply the correct print, wash, and cure profiles through ideaMaker. All datasheet tests were run on a DF2. Raise3D publishes no compatibility data for other 405 nm printers, so I won't sell it to you for that purpose.

Workflow
-
Before printing: Raise3D recommends shaking and stirring the cartridge thoroughly, storing it away from UV light, checking that the resin level is sufficient, and filtering out any cured particles between uses.
-
Printing: Use the DF2 or DF2+ with the official Raise3D profile. Test specimens for the datasheet were printed at 100 µm with a 14-second exposure per layer.
-
Washing: Use the DF Wash station with either IPA or TPM — the two solvents Raise3D approves for this resin. The DF Wash features dual-turbine agitation, twin-fan drying, and automatic drainage. Profiles load automatically via RFID or can be entered manually.
-
Curing: Use the DF Cure station, which combines 365, 385, and 405 nm LEDs with hot air up to 120 °C. As a reference, Raise3D cured test specimens for 20 minutes per side at room temperature.
-
Safety: Always wear gloves and avoid any skin contact while the resin is in liquid form.
Frequently Asked Questions
Is it similar to ABS?
Raise3D describes its strength and rigidity as comparable to ABS, with published values of 45 MPa tensile strength and a 2158 MPa modulus.
Can I print clips and snap-fit parts?
Yes — this is the most flexible resin in the Raise3D lineup, thanks to its 35% elongation at break, making it well suited for snap-fits and living hinges.
Why is the exposure time so long?
Raise3D used 14 seconds per layer at 100 µm for their datasheet test specimens. This is their reference profile; on the DF2, the correct profile is applied automatically.
Is it suitable for end-use parts?
Yes — Raise3D positions this resin for functional end-use parts where mechanical performance and durability matter.
Are the datasheet values from Raise3D?
Yes. All values come from the official Raise3D Technical Data Sheet (TDS), using specimens printed on a DF2 and post-cured in the DF Cure. Raise3D notes that these are typical reference values, and that real-world results will depend on part geometry, print orientation, and process parameters.
What solvent do I use for washing?
IPA or TPM — both are approved by Raise3D for use with the DF Wash station. Manual washing with IPA also works, but you won't have access to the automatic profile.
What format does it come in?
It comes in a 1 kg cartridge, compatible with the DF2's automatic resin feeding system.
How should I store it?
Keep it away from UV light, tightly sealed, and shake it well before each use — as specified in Raise3D's product guidelines.
