Formlabs High Temp Resin (Form 4)

A heat-resistant engineering resin designed for parts that must stay stiff and dimensionally stable in high-temperature environments — ideal for molds & inserts, hot-air / fluid flow prototypes, and heat-exposed mounts, housings, and fixtures.

Formlabs High Temp Resin (Form 4) cartridge
Category: Engineering
Technology: SLA
Strength: Stiff & rigid
Best for: Heat stability
Use case: Molds & inserts

Important: Heat performance depends on correct wash + post-cure processing. Use the manufacturer’s validated workflow for best results.

Heat-resistant parts that hold their shape when it matters

Formlabs High Temp Resin is engineered for applications where standard plastics soften, creep, or distort. Print detailed, accurate parts that stay rigid under heat — perfect for functional prototypes, fixtures, and manufacturing aids.

Use High Temp Resin to validate designs exposed to hot air or fluid flow, and to create heat-resistant tooling such as mold inserts, jigs, and mounts — without the lead time of machining or injection molding.

Why Choose Formlabs High Temp Resin?

Outstanding Heat Resistance

Designed for scenarios where parts are exposed to elevated temperatures and must remain rigid and stable.

Great for Tooling & Inserts

Perfect for producing mold inserts, jigs, and fixtures that benefit from fast iteration and complex geometry.

Accurate, Detailed Prints

Capture fine features and tight fits while testing function in real-world thermal conditions.

Fast Iteration Without Machining

Validate designs quickly and reduce turnaround time for heat-resistant prototypes and production aids.

Applications

High Temp Resin is ideal for functional testing and tooling in heat-exposed environments.

Consider High Temp Resin for:

  • Hot air, gas, and fluid flow prototypes (ducting, manifolds, housings)
  • Molds & inserts for forming and short-run tooling workflows
  • Heat-resistant mounts, brackets, and protective housings
  • Fixtures & jigs that must maintain accuracy when warm

Tip: Design with generous radii and consistent wall thickness where possible to reduce stress concentration under thermal cycling.

Workflow Overview

High Temp Resin uses a standard print + wash + post-cure workflow. For intended heat performance, follow the validated settings in the manufacturer documentation.

  • Print using the High Temp Resin preset for your Form 4 printer.
  • Wash using the validated wash method and timings.
  • Post-cure using the validated cycle to reach intended thermal properties.
  • Finish (support removal, light deburr) while preserving critical mating surfaces.
