Design of non-planar print paths for robotic 3D printing<\/p>\n\n\n\n\n\n\n\n

How can we approximate a shape using non-planar paths that follow user-perscribed directions? <\/figcaption><\/figure>\n\n\n\n

With the advent of robotic printing, it is possible to print material along 3D paths with variable orientation and thickness. Consequently, paths can be customized to enhance aesthetic or practical attributes such as surface quality or mechanical performance. However, there is a lack of methodologies for designing robot-fabricable, non-planar print paths. This research aims to address this gap with a focus on creating intuitive path design tools within the reach of designers and on considering fabrication constraints inherent to non-planar robotic 3D printing.<\/p>\n\n\n\n

Inspired by the ubiquitous key-framing technique in animation, where an input of limited degrees of freedom is used to describe a complex behavior, non-planar paths subject to the designer’s input are generated by interpolating a series of target curves on the surface of a mesh. This interpolation generates intermediary print paths with a direction that interpolates that of the targets. The resulting print paths have variable layer height, and their realization relies on variable end-effector orientation.<\/a><\/p>\n\n\n\n
