Direct fabrication of ceramic holding parts for high temperature experiments with Zetamix: a cost effective and time saving solution

Example at the Centre Des Matériaux (Evry, France) a MINES ParisTech - PSL research lab.

3D printing has demonstrated to be by far the greatest solution to produce on demand ceramic parts in small series. More and more laboratories and research centers equip themselves with Zetamix technology to fabricate a wide variety of parts, from heating cartridges to sample holders. Discover how the Mine Paris Tech, an education and research center, is using Zetamix filaments to improve the quality of their experiments.

 

 

Tensile test sample holder

The Centre des Matériaux[1] is a unit of MINES ParisTech[2] – PSL and is also a Joint Research Unit of the  CNRS[3] (UMR 7633 ) the CNRS, specialized in Materials Science and Mechanical Modeling with a particular attention to new materials obtained from innovative processes including those by AM. The aims of the studies are mainly focused on the influence of the fabrication processes on material properties as-produced or with aging conditions involving severe environment.

Most of these studies require specific samples for specific environment such as high temperature, and regular sample holders do not allow to achieve these experiments. Thanks to Zetamix alumina filaments, Sylvain Gailliegue and Alain Koster, both experts in high-temperature mechancial testing easily solved these issues for different case studies .

 

Tensile test sample holder

To achieve this goal, Sylvain needed a customized sample holder. This kind of part doesn’t exist in large quantity on the market and outsourcing the production would be too expensive. Indeed, to resist to heat treatment, they have to be in a refractory and stable ceramic like alumina. Thanks to Zetamix, Sylvain succeeded to produce a perfect fit alumina tensile test specimen holder that solved all the issues previously mentioned.

This facility would be the best solution with only slight modification. Actually, when the sample reach the targeted temperature in the range of 800°C-1100°C , Sylvain has to maintain it in a very precise location on the machine. Therefore, a specific sample holder is needed to achieve this goal. Moreover, this sample holder has to be resistant to high temperature and non-conductive for the inductive system. Thus, Sylvain decided to create a customized sample holder in a material which fills this two constraints : Alumina. Once again, alumina is an expensive material when it is product on small quantity, and Sylvain cannot afford to outsource the production of this sample holder. In the same way than for the previous sample holder, Sylvain printed an alumina part perfectly adapted to the machine thanks to Zetamix .

 

MINES Paris tech is equipped with 3D printers and furnaces to unbind and sinter printed parts. That is why using Zetamix filaments was particularly relevant to them: these filaments enable the laboratory  to produce parts with their own machines and to significantly improve the quality of their experiments with few investment.
