Formlabs ESD Resin is a specialized photopolymer material formulated for SLA 3D printing, particularly for use in Formlabs’ range of printers. This material is designed with a blend of photopolymer resins, photoinitiators, and conductive additives to provide electrostatic discharge properties.

Physical Properties

  • Density: Typically around 1.1–1.2 g/cm³
  • Tensile Strength: Generally falls within the range of 50-65 MPa, depending on the post-curing process
  • Surface Resistivity: Specifically engineered to achieve targeted levels of surface resistivity, making it suitable for ESD-sensitive applications

Aesthetic Quality

Formlabs ESD Resin produces prints with a smooth surface finish, usually available in dark or neutral colors to signify its specialized use. The material is good at capturing details and is suitable for both functional and aesthetic applications where ESD properties are essential.

Durability and Usage

Engineered for applications requiring ESD-safe material, this resin is well-suited for electronic housings, fixtures, or any components that should not accumulate static electricity. It offers good mechanical properties and is robust enough for long-term use in static-sensitive environments.


Post-processing involves washing the printed object in a solvent like isopropyl alcohol to remove uncured resin, followed by UV curing to optimize its mechanical properties and ESD characteristics. The material can also be sanded, drilled, and painted, although special coatings might be required to maintain its ESD properties.

Environmental Impact

Like most SLA resins, Formlabs ESD Resin is not biodegradable and needs to be disposed of responsibly to minimize its environmental impact. It is synthesized from non-renewable resources, making it less eco-friendly compared to bio-based materials like PLA.

In summary, Formlabs ESD Resin offers a specialized material designed for applications requiring electrostatic discharge properties. While it may not be the most eco-friendly option, its unique ESD capabilities make it invaluable for specialized, static-sensitive applications. Responsible handling and disposal are essential due to its environmental considerations.
