Deformations of hollow channels printed with Stereolithography (SLA) and Fused Deposition Modeling (FDM) technologies. A total of five samples were measured for each experimental point, and error bar heights represent one standard deviation. Designed vs measured channel diameter measurements are presented for (a) the deformation of channels in the X direction (width of the channels) and for (b) the deformation of channels in the Y direction (height of the channels).
