High-Stiffness Engineering Material for Functional Prototypes
Tough 2000 Resin V2 is the stiffest and strongest material in the Formlabs Tough family. Designed to withstand high stress and resist deformation, it is the ideal choice for functional assemblies, rugged housings, and mechanical connections. When printed on the Form 4, it leverages the Low Force Display (LFD) engine to deliver exceptional dimensional accuracy and a professional matte finish.
Key Features
-
ABS-Like Rigidity: With a high tensile modulus of 2.4 GPa, Tough 2000 V2 mimics the mechanical behaviour of ABS, making it perfect for parts that must maintain their shape under load.
-
Enhanced Fracture Toughness: This V2 formulation features double the fracture toughness of the legacy version, ensuring that parts can absorb energy and resist cracking during assembly or functional testing.
-
Superior Creep Resistance: Engineered to maintain its dimensions over time, this resin resists "creeping" or bowing under sustained stress, which is critical for load-bearing brackets and enclosures.
-
Premium Matte Surface: The dark grey, low-gloss finish hides layer lines and provides a professional look right off the build platform.
Ideal Applications
-
Functional Prototypes: Simulating the fit and feel of injection-molded ABS parts.
-
Housings & Enclosures: Protective covers for electronics or mechanical assemblies.
-
Mechanical Connectors: Snap-fits, friction-fits, and structural brackets.
-
Manufacturing Tooling: Rigid jigs and fixtures that require high dimensional stability.
FAQ
What is the Difference Between V1 and V2?
The V2 formulation is specifically optimized for the Form 4's LFD light engine. It offers significantly improved fracture toughness (resistance to crack propagation) and faster print speeds while maintaining the high stiffness users expect from Tough 2000.
Can I Use Tough 2000 V2 for Long-Term Outdoor Use?
While Tough 2000 is highly durable, it is an SLA resin and may experience some UV degradation over extended outdoor exposure. For parts requiring long-term UV stability, we recommend painting the parts with a UV-protective coating or exploring the Formlabs Grey Pro or Rigid libraries.
Is Post-Curing Required?
Yes. To reach the 50 MPa tensile strength and 2.4 GPa modulus, parts must be post-cured.
