초록

Large objects, such as human-shaped manikins, need to be segmented forthree-dimensional (3D) printing, and then glued. This paper presents quantitative andexperimental results on filament dimension changes to show whether segmented partscan be combined using location-fit or magnets. Two kinds of filaments, poly lactic acid(PLA) and thermoplastic polyurethan (TPU), are used in the 3D printing of two types of teststructures, a hole/shaft structure and a magnet-in-hole structure. Both horizontal and verticalfilament dimension changes are measured. It was found that the hole sizes should beexpanded to reflect the expansion of the wall thickness in the horizontal direction. In thevertical direction, the stacking of filament layers slightly reduced the total height. In particular,we derive an equation that can explain why the minimal thickness from slicing softwareg-code generation varied depending on the object inclination angle. Finally, theequation results are compared with those of slicing software.
