Filament with ceramic powder that allows to obtain black zirconia parts after debinding and sintering processing.

Nanoe is a renowned French company founded in 2008 and specialised in the production of innovative materials. It stands out mainly in the production of ceramic powders, with a production capacity of more than 100 tons of high purity ceramic powder per year.

Taking advantage of the high degree of know-how in the field of ceramics, in 2018 they created the Zetamix brand, the first brand of filaments with technical ceramics aimed at producing all-ceramic parts in an accessible and affordable way.

Nanoe currently has three ceramic filaments for technical applications: White Zirconia, Black Zirconia and Alumina.

Zetamix Black Zirconia is a filament consisting of 85 % by weight of stabilised black zirconia powder and 15 % by weight of binder. Black zirconia is one of the most common substitutes for black diamond in jewellery. Its high hardness and the possibility of being polished to a shiny finish make it an economical and quality alternative.

This is why Zetamix Black Zirconia is a perfect filament to produce jewellery pieces impossible to obtain by traditional cutting.

Zetamix ceramic filaments make it possible to obtain fully ceramic parts easily in three steps:

  • Printing: Zetamix ceramic filaments can be easily printed on virtually any direct extruder printer, as they require printing temperatures between 150 and 180 ºC and a base temperature of 40 ºC.

    • Debinding: Debinding consists of two stages, chemical debinding in acetone using an ultrasonic bath such as Zetadebinder and thermal debinding prior to sintering.
    • Sintering: Finally, the part is sintered by heat treatment to obtain a completely ceramic part.

    Ceramic printing has been a great challenge due to its complexity and high cost. Thanks to Zetamix ceramic filaments, it is possible to obtain complex all-ceramic parts in an economical and simple way.

    It is recommended to carefully follow the design guide available in the download tab when designing the parts to be made with Zetamix Alumina.

    Printing:

    When printing, the following parameters must be applied:

    Printing temperature: 170 ºC
    Base temperature: 40 ºC
    Nozzle size: 0.4 - 1.0 mm
    Coating height: 0.3 - 0.1 (0.15 recommended)
    Print speed: 20 - 35 mm/s
    Shrinkage: 1 mm to 20 mm/s
    Perimeters: At least 2
    Filling: 5 % - 100 % Filling: 5 % - 100 % Filling: 5 % - 100 % Filling: 5 % - 100
    Top and bottom wall thicknesses: At least 1 mm
    Substrates: Supports: Supports in the same material and in soluble materials.
    Adhesion to backing: Glass backing and Magigoo adhesive recommended.

    Zetamix ceramic filaments are only compatible with direct extruders. The spool should be placed on top of the printer so that the path between the spool and the extruder is as straight as possible.

    It is advisable to reduce the extruder tension to a minimum to prevent the filament from deteriorating.

    Debinding:

    Debinding consists of two stages, a chemical and a thermal stage.

    Chemical debinding: The part must be treated for at least 2 hours in an ultrasonic bath with acetone at 40 ºC. Afterwards, the piece must be left to air dry for at least 2 hours. If the treatment has been successful, the piece should lose 5% of its weight.

    Heat debinding: The pieces must be placed in a crucible with refractory powder to support the shrinkage of the piece and to serve as a support during the process. A heat treatment should then be applied consisting of heating the parts from 20 ºC to 500 ºC at a rate of 8 ºC/hr. For small parts, the debinding time can be reduced by applying the following heat treatment:

    Initial TemperatureFinal TemperatureSpeed
    20 125 35 ºC/h
    125 200 50 ºC/h
    200 215 22 ºC/h
    215 250 11 ºC/h
    250 280 20 ºC/h
    280 320 8 ºC/h
    320 510 24 ºC/h

    Sintering:

    After debinding, the part must be sintered by applying the following heat treatment:

    • Heat from 20 ºC up to 1475 ºC at a speed of 50 ºC/h.
    • Hold at 1475 ºC for 2 hours
    • Cool to room temperature at a rate of 100 ºC/h
