Abstract: Usually, objects are horizontally sliced when printed by 3D printers. Therefore, if an object to be printed, such as a collection of fibers, originally have natural direction in shape, the printed direction contradicts with the natural direction. By using proper tools, such as field-oriented 3D paint software, field-oriented solid modelers, field-based slicing algorithms, and non-horizontal FDM 3D printers, the natural direction can be modeled and objects can be printed in a direction that is consistent with the natural direction. This consistence results in embodiment of momentum or force in expressions of the printed object. To achieve this goal, several manufacturing problems, but not all, have been solved. An application of this method is (Japanese) 3D calligraphy.
