Formlabs High Temp Resin is a unique material crafted for SLA 3D printing with an emphasis on extreme thermal stability. With a heat deflection often surpassing 200°C and robust mechanical attributes, this resin stands out for its high-temperature applications such as molds and thermal cycling components. Its unmatched thermal attributes solidify its place in specialized industrial scenarios.

Physical Properties

  • Density: Typically around 1.15–1.25 g/cm³
  • Tensile Strength: Generally in the range of 50-65 MPa, depending on post-curing processes
  • Heat Deflection Temperature: Exceptionally high, often exceeding 200°C after adequate post-curing

Aesthetic Quality

Formlabs High Temp Resin usually produces prints with a smooth surface finish, most often available in translucent or light-coloured hues. The material is designed more for its functional attributes than aesthetic appeal but still maintains a high-quality appearance.

Durability and Usage

Engineered for high-temperature applications, this resin offers outstanding thermal stability and resistance. It’s particularly well-suited for molds, environmental testing, and components that will undergo thermal cycling. Its high Heat Deflection Temperature makes it unique among SLA resins and ideal for specialized industrial applications.


Standard post-processing involves washing the print in a solvent like isopropyl alcohol to remove any uncured resin, followed by UV curing to maximize its mechanical properties and thermal stability. Due to its robust nature, the material can also be sanded, machined, and painted, although specialized adhesives and coatings may be required.

Environmental Impact

Like most photopolymer resins, Formlabs High Temp Resin is not biodegradable and should be disposed of responsibly to minimize its environmental impact. The material is synthesized from non-renewable resources, making it less eco-friendly compared to bio-based materials such as PLA.

In summary, Formlabs High Temp Resin offers a high-performance, specialized material designed for applications requiring extreme thermal resistance. While not as environmentally friendly as some other 3D printing materials, its exceptional heat resistance and mechanical properties make it indispensable for specific, high-temperature applications.
