(A,B) Surface scans using a high-resolution 3D macroscopic measurement system (VR-5200 3D optical Profilometer, 0.1 µm resolution) using bright field (real) and high-resolution laser (high). High-resolution images allowed to determine values for surface roughness in (C) mean peak (Ra) and (D) averaged roughness (Rz). Every dot represents the arithmetic mean of three technical replicates. (E, F) Dimensional print accuracy was determined by manually measuring height and diameter discs from each group (n = 50 specimens, one measurement/specimen) using a Mitutoyo 7309 Pocket Thickness Gauge. Values where related to STL file dimensions (dashed line). Small subscript v refers to samples printed in vertical direction, subscript h in horizontal direction
