Formlabs Rigid 10000 Resin is a high-performance photopolymer crafted for Formlabs’ SLA 3D printers. Known for its exceptional tensile strength (75-90 MPa) and a Heat Deflection Temperature surpassing 110°C, Rigid 10000 stands out as a top choice for aerospace and engineering applications, high-precision molds, and any project demanding supreme rigidity.

Physical Properties

  • Density: Typically around 1.2–1.3 g/cm³
  • Tensile Strength: Exceptionally high, often in the range of 75-90 MPa, depending on the post-curing treatment
  • Heat Deflection Temperature: Remarkably high, often exceeding 110°C after post-curing

Aesthetic Quality

Formlabs Rigid 10000 Resin produces prints with a smooth and premium surface finish, often available in light or neutral colors. The material excels at capturing intricate details, making it suitable for both functional components and aesthetically pleasing models.

Durability and Usage

Designed for applications requiring extreme rigidity and low deformation under load, this resin is especially suitable for structural components in engineering and aerospace, load-bearing parts, and high-precision molds. Its unique blend of resins and additives provides unparalleled stiffness, making it one of the most rigid materials in the Formlabs portfolio.


The post-processing steps typically include washing the printed object in a solvent, usually isopropyl alcohol, to remove uncured resin. This is followed by UV curing to maximize the material’s mechanical properties. Due to its extreme rigidity, the material can be sanded, machined, and painted, although special adhesives and coatings may be necessary for optimal results.

Environmental Impact

Like most photopolymer resins, Rigid 10000 is not biodegradable and is made from non-renewable resources. This makes it less environmentally friendly compared to bio-based materials like PLA. Special disposal methods should be followed to minimize its environmental footprint.

In summary, Formlabs Rigid 10000 Resin offers a specialized, high-stiffness material for applications requiring unparalleled rigidity and low deformation. While it may not be the most environmentally friendly option, its exceptional mechanical properties make it invaluable for specialized, high-stress applications. Responsible handling and disposal are essential given its environmental impact.
