A 3D X-ray microscope (XRM) combines micro-computed tomography with microscopic visualisation. These analyses were conducted using a Bruker Skyscan 2214 CMOS 3D X-ray microscope, operating a nanofocus X-ray source with a focal spot below 500 nm. The voxel size was 1.6 m, and the operating voltage was 45 kV. The 3D.SUITE software was used for visualisation. These studies were performed on small, 10×10×4 mm 2 printouts with 100% infill.
