What is Formlabs High Temp Resin?

Formlabs High Temp resin is an SLA material for detailed parts exposed to heat with minimal loading. Its heat deflection temperature at 0.45 MPa is 120 °C (248 °F) after the specified post-cure, rising to 238 °C (460 °F) with an additional thermal cure. These are test values under defined conditions, rather than continuous operating temperatures.

Formlabs High Temp Resin Overview

Applications

Formlabs High Temp resin’s thermal stability makes it suitable for prototypes and tooling exposed to elevated temperatures. Typical applications include hot-air and fluid-flow test components, heat-resistant mounts, and mould inserts.

Key Product Benefits

  • High heat resistance after post-curing
  • High stiffness

Tolerances

For well-designed parts, dimensional accuracy of ±0.3% of the nominal dimension, with a minimum tolerance of ±0.3 mm (±0.012 in.), can typically be achieved. Tolerances may vary depending on part geometry.

Values are based on manufacturer testing and are approximate. Actual part properties may vary with geometry, machine settings, and processing conditions. This information is not binding and is not deemed to be certified. When performance is critical, consider independent laboratory testing of the material or finished part.
*Starred values follow a 120-minute post-cure at 80 °C plus a 180-minute thermal cure at 160 °C. The final row follows a 60-minute post-cure at 60 °C.
