Resin (MSLA)

High Temp Resin 3D printing

High Temp is the resin with the highest heat deflection temperature in our catalog, for parts in contact with hot air and fluids. We print it in Brescia with MSLA.

What it is for

High Temp resin is used for parts in contact with hot air and fluids: test ducts and manifolds, nozzles, enclosures close to heat sources, tools and fixtures for thermal processes, inserts for trial molds. It keeps its shape at temperatures at which the other resins deform.

It is stiff and brittle: do not choose it for parts that take impacts or have to flex, where the Tough resins are needed. Under load it holds less than the figure at 0.45 MPa suggests: at 1.8 MPa the data sheet reports 101 °C. For mechanical loads at high temperature move to a filament such as PEEK or Ultem.

Typical values from the makers' data sheets, measured on specimens under the conditions stated. They are not guaranteed design values: for a critical application ask us for a test on your part.

Treatments after printing

The table sets the values after a 60-minute post-cure at 60 °C next to those after 120 minutes at 80 °C followed by 180 minutes at 160 °C: the 238 °C heat deflection temperature needs the 160 °C step.

Design limits

Build volume: 353 × 196 × 350 mm
Minimum wall: 1 mm
Dimensional tolerance: ±0.3 mm up to 100 mm, ±0.3% above

These are the limits of the process, the same for every variant unless stated. For critical dimensions, talk to us before printing.

Which variant to choose

High Temp is the resin for temperature. If you need high stiffness as well as heat resistance, choose Rigid 10K; if the part works under continuous load in heat, move to the high-performance filaments, such as Ultem or PEEK.

FAQ

Frequently asked questions

It depends on the treatment. After 60 minutes at 60 °C the data sheet reports a heat deflection temperature of 120 °C at 0.45 MPa. After 120 minutes at 80 °C followed by 180 minutes at 160 °C it reports 238 °C at 0.45 MPa and 101 °C at 1.8 MPa (ASTM D648). The higher value therefore needs the 160 °C step.

Yes. With the full treatment the data sheet reports a tensile strength of 49 MPa and an elongation at break of 2.3%, against 58 MPa and 3.3% after the 60-minute post-cure at 60 °C alone (ASTM D638). The part gains heat resistance and becomes a little more brittle.

It is used for test ducts, manifolds and inserts for short-run molds. Allow for its brittleness and for the fact that under load the useful temperature drops. Compatibility with a specific fluid has to be checked: state it in your request together with temperature and pressure.
