Resin (MSLA)

Rigid 10K Resin 3D printing

Rigid 10K is a very stiff glass-filled resin, for parts that must not flex and that work in heat. We print it in Brescia with MSLA.

What it is for

Rigid 10K is used for parts that must not flex: inserts and cavities for short-run molds, jigs and gauges, forming tools, models for aerodynamic tests, supports and components exposed to heat and fluids. It is a glass-filled resin, very stiff, with a smooth surface and good dimensional stability.

It is brittle: the elongation at break on the data sheet is 1%. Do not choose it for parts that take impacts or drops, nor for snap fits, where the Tough resins are needed. To get stiffness with more toughness, consider a carbon-fiber filament, such as those of the nylon family.

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 70 °C next to those after the further 125-minute thermal cure: the 218 °C heat deflection temperature needs the thermal cure.

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

Rigid 10K is the resin for stiffness and heat: after post-cure the data sheet reports a tensile modulus of 10 GPa (ASTM D638). Choose High Temp if temperature matters more than stiffness; the Tough resins if the part has to absorb impacts or flex.

FAQ

Frequently asked questions

It depends on the treatment. After the 60-minute post-cure at 70 °C the data sheet reports a heat deflection temperature of 163 °C at 0.45 MPa and 82 °C at 1.8 MPa (ASTM D648). With the further 125-minute thermal cure the values rise to 218 °C and 110 °C. State in your request which one you need.

It is a typical use for short runs and trials: stiffness and heat resistance let it stand pressure and temperature for a limited number of cycles. Service life depends on the material injected, on the geometry and on the molding settings: it cannot be predicted in general and has to be tried.

Yes, that is the other side of stiffness. After post-cure the data sheet reports an elongation at break of 1% (ASTM D638) and a notched Izod impact of 16 J/m (ASTM D256). Avoid thin walls exposed to impacts, sharp corners under load and snap fits; allow generous fillets.
