The feel of 3D prints: An objective and perceptual characterization of FDM surface roughness

Since the expiration of the FDM printing patent by Stratasys in 2009, Fused Deposition Modeling(FDM) printing has taken a large step towards accessible consumer 3D printing. Also, more knowledge is sought in the process of FDM printing and optimizing quality as the layer by layer deposition inevitable results in poor surface quality. This study...
