3D printed alumina crucibles improves design and productivity

3D printed alumina crucibles improves design and productivity

Bespoke 3D printed alumina crucibles were required. The standard ones just didn’t do the job properly. Now we are more productive. says Nicolas Parisse, Quality technician.

Moreover, crucibles matching his specifications didn’t exist on the market. Naturally Nicolas switched to 3D printed alumina crucibles. This way he got the required ceramic parts with the same properties as parts made by moulding or injection. Plus he was able to make unlimited numbers of designs in less than a week.

Considering Factors

Firstly we check the density and the surface condition of the pressed pellet. Secondly we check the quality and the homogeneity of the microstructure. To do this we break the pellets into smaller pieces so they aren’t too large for the microscope. We place these on the crucible. The crucible is put in a furnace and then thermal etching tests are conducted.

Indeed, Nicolas was looking for a numbered compartmentalised crucible capable of withstanding high temperatures (400°C.h-1 to 1500 °C) not available on the market.

The Solution

3D printed alumina crucibles are now the only way forward.

For this reason Nicolas designed an alumina crucible equipped with 15 numbered compartments.

The advantages provided by this new crucible design are undeniable. We no longer have the risk of mixing samples. We have improved our process and the relevancy of the tests we need to do. Furthermore, 3D printed alumina crucibles provide a time saving. The team can handle samples more quickly and is liberating from the mental workload of making a mistake.
