Formlabs Tough 2000 Resin is designed exclusively for SLA 3D printing on Formlabs’ printers. A blend of photopolymer resins and innovative additives culminate in superior toughness and stiffness, ideal for demanding engineering challenges. Whether you’re crafting functional prototypes, mechanical components, or parts under consistent stress, this resin’s robust formulation ensures exceptional performance and longevity.

Physical Properties

  • Density: Usually falls within the range of 1.1–1.2 g/cm³
  • Tensile Strength: Typically between 55-70 MPa, contingent on the post-curing process
  • Heat Deflection Temperature: Generally lies between 70-90°C after post-curing

Aesthetic Quality

Formlabs Tough 2000 Resin produces prints with a smooth and high-quality surface finish. The material is generally available in light or neutral colors and excels at capturing fine details, making it suitable for both functional and aesthetic applications.

Durability and Usage

This resin is engineered for applications that require enhanced toughness and stiffness compared to standard resins. It’s particularly well-suited for functional prototypes, mechanical parts, and any components exposed to sustained stress or strain. The Tough 2000 formulation provides a higher level of durability, making it a robust option for challenging engineering applications.


The standard post-processing workflow includes washing the print in a solvent like isopropyl alcohol to remove any residual uncured resin. This is followed by UV curing to improve the material’s mechanical and thermal properties. The resin can be further sanded, drilled, and painted, and typically adheres well to common adhesives and coatings.

Environmental Impact

Like most photopolymer resins, Formlabs Tough 2000 Resin is not biodegradable and necessitates special disposal methods to minimize its environmental impact. Moreover, the resin is synthesized from non-renewable resources, making it less eco-friendly compared to bio-based materials like PLA. Responsible usage and disposal are crucial for mitigating its environmental footprint.

In summary, Formlabs Tough 2000 Resin offers a specialized material that excels in both toughness and stiffness, making it ideal for a wide array of challenging industrial and engineering applications. Although its environmental impact is a consideration, the resin’s advanced performance attributes make it a highly valuable choice for tasks requiring increased durability and mechanical strength.
