This paper presents an approach to curved layer path planning on a 5-axis printer, utilizing two additional printer degrees of freedom to provide a curved layer path planning strategy.
Purpose This paper aims to provide an approach to print shell-type objects using a 5-axis printer. The proposed approach takes advantage of the two additional printer degrees of freedom to provide a curved layer path planning strategy. Design/methodology/approach This paper addresses curved layer path planning on a 5-axis printer. This printer considers movements along the three usual axes together with two additional axes at the printing table (rotation and tilt), allowing to build more complex and reliable objects. Curved layer path planning is considered where polygons obtained from the slicing stage are approximated by linear and cubic splines. The proposed printing strategy consists in building an inner core supporting structure followed by outer curved layers. Findings The curved layer path planning strategy is validated for shell-type objects by considering a 5-axis printer simulator. An example with an aeronautic object is presented to illustrate the proposed approach. Originality/value The paper presents an approach to curved layer path planning on a 5-axis printer, for shell-type objects.
