SLA Ceramic-Filled High Temperature Resin 3D Printing

A ceramic-filled, high-temperature SLA resin — ceramic-hard stiffness and dimensional stability to a 218 °C heat deflection temperature, the highest figure of any material we print. RYSE 3D prints it on the Formlabs Form 4L in Shipston-on-Stour for fine-detail rigid parts that see real heat: short-run mould tooling, thermal test parts, wind-tunnel models and stiff fixtures.

Overview

Ceramic-hard stiffness that takes the heat

Most resins soften long before 100 °C. Ceramic-filled is different — the ceramic loading gives it a 218 °C heat deflection temperature, 65 MPa tensile strength and ceramic-hard stiffness, so parts hold their shape under heat and load. That makes it the resin for high-temperature 3D printing: heat-resistant tooling, mould and casting inspection, thermal testing and stiff fixtures with the fine detail of stereolithography.

Printed and finished in-house on our UK SLA platform, Ceramic-Filled comes off the machine with a smooth, stone-like rigid surface — dimensionally stable, stiff and ready for hot, demanding environments. It is the only resin in our range that will sit against a heated tool or hot air without walking out of tolerance.

Note that it trades toughness for stiffness. At around 1% elongation at break it is rigid and brittle — it will crack rather than flex. Specify it for static, clamped and heat-exposed parts, and read the honest limits below before you put it anywhere it can be knocked.

Why Ceramic-Filled

Why choose ceramic-filled resin

218 °C heat resistance

Our most heat-resistant material in any process — parts stay dimensionally stable at temperatures that soften standard resins before 100 °C.

Ceramic-hard stiffness

Ceramic loading gives exceptional rigidity — parts hold shape under clamping, load and heat rather than creeping.

Heat-resistant tooling

Layup and forming tools, mould and casting inspection parts, and fixtures that work next to heat without a machined-metal bill.

Fine SLA detail

Sharp features and a smooth surface straight off the machine at 25–100 micron layers — rigid parts with real precision.

65 MPa tensile strength

Strong as well as stiff — the highest tensile strength of any resin in our SLA range.

Simulates filled thermoplastics

The stiffness and stone-like feel make it a credible stand-in for glass- and fibre-filled mouldings at the prototype stage.

Design guidance

Designing for ceramic-filled resin

Typical guidelines for SLA Ceramic-Filled on the Form 4L. Being rigid at around 1% elongation, avoid thin unsupported walls and snap-fits. We'll confirm the specifics for your part with a free design-for-additive review at quote.

Design feature Typical guideline
Build envelope (Form 4L) 353 × 196 × 350 mm
Layer thickness 25–100 microns
Minimum wall thickness 0.5 mm
Tolerance ±0.15 mm or ±0.2%
Supports Required for SLA — removed and finished in-house, so tell us which faces are cosmetic or working surfaces
Orientation We orient in PreForm to keep supports off tooling faces and to avoid peel forces cracking large flat rigid sections
Brittleness At ~1% elongation, design out snap-fits, living hinges and thin cantilevers — add fillets and generous radii at every corner
Service temperature Stable to a 218 °C heat deflection temperature — the highest figure across everything we print
Bigger than the platform? Split, print, bond and finish the assembly — or move to FDM for a one-piece part up to 900 mm
Finish Smooth, stone-like rigid finish as-printed; can be sanded for a working tool face
Our SLA platform

Printed on the Formlabs Form 4L in open mode

Every Ceramic-Filled part we ship is printed on the Formlabs Form 4L, washed on the Form Wash L and post-cured on the Form Cure L — print, wash, cure and finish all in-house, so nothing leaves the building between the CAD and the finished part. Build envelope is 353 × 196 × 350 mm, large enough for a full-size mould insert or fixture in a single piece rather than split and bonded.

We run the Form 4L in open mode, which means we are not restricted to a single supplier's resin range. That is what lets us offer a ceramic-filled high-temperature grade alongside the rest of our resin range, and choose the right resin for your part rather than the one the machine came with.

Honest limits

Where ceramic-filled resin is the wrong call

Ceramic-Filled buys you heat and stiffness that nothing else in our range gets close to. What it does not buy you is toughness. These are the cases where something else wins — told straight, so you don't find out after the first batch.

Anything that takes a knock

At around 1% elongation at break this is a brittle material — it cracks rather than flexes. For a part that gets dropped, handled or assembled repeatedly, SLA Black PU at 79% elongation is the right resin.

Snap-fits, clips and living hinges

Any feature that has to deflect to work will snap off on first assembly. Design them out, or move the part to Black PU or an SLS nylon where ductility is available.

Load-carrying parts at temperature

218 °C is a heat deflection figure, not a licence to carry load hot. For a rigid part that must hold load and heat together, PET-CF at 205 °C or PPA-CF at 192 °C are engineering thermoplastics rather than filled photopolymers.

Parts over 350 mm

The Form 4L platform is 353 × 196 × 350 mm. Beyond that a part has to be split and bonded — and a bonded joint in a brittle material is a weak point. Our FDM range prints up to 900 mm in one piece.

Support-free complex geometry

SLA needs supports and they touch the part. Internal lattices, trapped voids and all-over cosmetic surfaces are better on SLS, where the powder bed carries the part and nothing needs removing from a brittle surface.

Outdoor and UV exposure

Cured photopolymers discolour and embrittle under sustained UV, and this one starts brittle. For parts that live outside, FDM ASA is UV-stable and built for it.

Compare

SLA Ceramic-Filled vs Black PU vs Clear

One question decides this: does the part see heat, or does it get handled? Ceramic-Filled is the stiff, high-temperature resin and the most brittle of the three. For a tough, impact-tolerant part see SLA Black PU; for optical clarity, SLA Clear; for flexibility, Flexible 80A. Full range on all 3D printing materials.

Property Ceramic-Filled (this page) SLA Black PU SLA Clear
Character Ceramic-hard, stiff, brittle Tough, cast-urethane-like Optically clear, polishable
Heat deflection 218 °C 70 °C 61 °C
Ultimate tensile strength 65 MPa 40 MPa 51 MPa
Elongation at break 1% 79% 10%
Impact tolerance Poor — cracks rather than flexes Good Moderate
Minimum wall thickness 0.5 mm 0.5 mm 0.5 mm
Best for Heat-resistant tooling and rigid fixtures Detail plus handling toughness Lenses, light-pipes, see-through parts

Note: all three are SLA photopolymers printed on the same platform, so these figures sit on a comparable footing — unlike cross-process comparisons, where tensile and impact are quoted to different standards and cannot be ranked against each other. Heat deflection is the deciding figure here, and 218 °C is the highest across every material we print in any process.

FAQ

SLA Ceramic-Filled resin FAQ

What is SLA ceramic-filled (high-temperature) resin?
It's a rigid SLA resin loaded with ceramic particles, giving ceramic-hard stiffness and a 218 °C heat deflection temperature — our most heat-resistant material in any process. RYSE 3D prints it on the Formlabs Form 4L for fine-detail parts that stay stable under heat.
How heat-resistant is ceramic-filled resin?
It holds its shape to a heat deflection temperature of 218 °C — far beyond standard resins, which typically soften below 100 °C. That makes it suitable for tooling and test parts that sit against hot components, hot air or heated processes. It is the highest heat deflection figure across every material we print, in any process.
What is high-temperature resin used for?
Heat-resistant tooling, short-run injection mould masters and inserts, moulds for blow moulding and thermoforming, mould and casting inspection parts, thermal test parts, stiff jigs and fixtures, under-bonnet style prototypes, ducting models and wind-tunnel parts — anywhere stiffness and heat stability decide the part.
How stiff is ceramic-filled resin — and is it brittle?
Very stiff — ceramic-hard, with 65 MPa tensile strength, the highest of our SLA resins. The trade-off is around 1% elongation at break, so it is rigid and brittle rather than tough: right for static, clamped or heat-exposed parts, but not for snap-fits or impact loading. For a tough part, SLA Black PU is the better fit at 79% elongation.
Can you 3D print heat-resistant tooling in the UK?
Yes — ceramic-filled resin is made for it. Its stiffness and 218 °C stability suit forming and layup tools, short-run mould inserts and inspection fixtures that would distort in standard resins, all printed with fine SLA detail and a smooth working surface, in-house in Shipston-on-Stour and shipped UK-wide.
Can ceramic-filled resin be used for injection mould tooling?
For short runs and prototype tooling, yes — mould masters and inserts, blow moulding and thermoforming tools are all within scope, and the 218 °C heat deflection is what makes that possible. It is not a substitute for hardened steel tooling at production volumes. Tell us the shot count, the material being moulded and the process temperature at quote and we'll tell you honestly whether it will survive.
Should I choose Ceramic-Filled or Black PU?
Choose on heat versus handling. Ceramic-Filled is stiffer, stronger and stable to 218 °C, but brittle at 1% elongation. Black PU is tough at 79% elongation and survives impact and assembly, but its 70 °C heat deflection is the lowest we print. If the part sees heat, choose Ceramic-Filled; if it gets handled, choose Black PU.
What machine do you print SLA on?
The Formlabs Form 4L, with a 353 × 196 × 350 mm build envelope, running in open mode so we are not tied to one supplier's resin range. Parts are laid out and supported in PreForm, washed on the Form Wash L and post-cured on the Form Cure L, then supports are removed and the part finished by hand — all in-house in Shipston-on-Stour.
