3D Printing. Ceramic.
3D Printing in our Ceramic materials gives your designs excellent temperature resistance, high strength and low conductivity.
Another recent addition to our 'Strong & Durable' and 'Fine Detail' service, our Ceramic based 3D printing service gives you an ideal material where you need Strength, Smooth surface finish and excellent temperature resistance. Designs produced in Ceramic can have fine detail and the off white colour enhances temperature resistance when exposed to local heat sources.
We give you two ceramic options, our original Ceramic SLA and the new Zirconia ZrO2 nano jetted material.
Neither processes require kiln firing.
Ceramic infused resin (SLA)
3D Printing in our resin infused Ceramic material is via the Stereolithography (SLA) process where the base liquid resin cured layer by layer by a laser. Each layer is 100 micron thick and gives a nice smooth surface finish. We recommend that wall thickness or features in your design should be in excess of 0.5mm to ensure integrity.
High Temperature Resistance.
Our Ceramic SLA 3D printing sits on both our 'Strong and Durable' and 'Fine Detail' services on account of parts being strong yet capable of resolving features down to 0.5mm. Stand out properties include a high temperature resistance and large build volume. To summarise, 3D Printed Ceramic gives your designs:
- High temperature resistance of 132ºC (268ºC after an optional thermal postcure.)
- Smooth surface finish.
- Excellent aesthetics in a 'White' colour.
- Fine individual details and wall thicknesses down to 0.5mm.
- High levels of accuracy & dimensional stability.
- Strength & Durability with robust material properties.
- Electrical properties include very low conductivity.
Include designs required to work in close proximity to localised heat sources such as lasers, or to produce complex wave guide or antenna substrate designs for full or selective metalization. Motorsport teams utilize the material for producing wind tunnel test parts.
Ceramic. Zirconia ZrO2.
New. We now offer you the ceramic Zirconia ZrO2 material 3d printed via the Xjet Nanoparticle jetting process. Nanoparticle jetting gives you a good size build area at 500 x 280 x 200mm with high resolution and fine detail. The 10-15um layer height is one of the finest available in additive manufacturing, which along with a soluble support facilitates intricate design features.
Parts are formed by jetting a special liquid containing nano particles which then evaporates after printing, leaving the ceramic element. 'Green' parts are then placed in a furnace to under go a sintering.
Published accuracy figures are impressive at +/- 20 to 50 um over 50mm.
More information to follow.
UPDATE. December 2018. The process is currently 'pre beta' and development continues. Parts are showing excellent detail as would be expected from the 10um layer height while the ingenious soluble support system allow for complex geometries. Temperature resistance is around 1000 deg C and the material is an excellent electrical Isolator.
The build volume is currently reduced from the dimensions noted above.
We're happy to quote your designs on a 'check build' basis.
At this time the process is best suited to small, detailed parts within a build volume of 30x30x20mm but large batches of parts are possible.

Ceramic 3d printing.
Ceramic nozzle, 3D printed for a factory production line application.
The design pictured was 3d printed in our ceramic material to take advantage of it's superior temperature resistance. The part delivers cooling air but works in very close proximity to a high temperature laser. The off white color means helps manage ambient in the environment.
3D Printed Ceramic Wave Guide.
Our Ceramic material offers excellent electrical properties for use as a substrate in wave guide applications, in the microwave spectrum of frequencies.
