On tuesday we performed a first vacuum test, to see if our 3D-printed sensor head plates show any sort of outgassing or deformation and thereby if 3D printed items are generally usable in the expected pressure environment.
The test was successful, no one got harmed, the laboratory is still intact and no outgassing or deformation has been registrated.
Now, further and more detailed tests will hopefully confirm this result.
