Complex high-precision mechanical devices can be fabricated using 3-dimensional printing technology with the help of computer-aided design. Using 3D stereolithography, we have constructed a cryogenic goniometer for measurements in pulsed magnetic fields of up to 100 T, at temperatures as low as 0.5 K. The goniometer allows up to two samples to be rotated in situ to a precision of 0.1 degrees, so that the field can be applied at many different angles to the samples’ symmetry directions. The materials used for such pulsed-field probes must be stable in temperatures down to 0.5 K, non-metallic, to avoid eddy-current heating, and durable; we will review the properties of several materials tested in developing the goniometer. Following its success, we suggest that 3D printing is now a viable technology for pulsed-field and other cryogenic probes.
