dc.description.abstract | Additive manufacturing (AM), also known as 3d printing, has become a hot topic in
academia and industry in the past decades. For a typical layer-based additive manufacturing
where the object is printed in a layer-by-layer fashion, the battle to reduce or even eradicate the
support structure is always faced by researchers and industrial practitioners. The newly emerging
multi-axis printing platform inspired by the five-axis machine tool opens new directions, such as
surface quality improvement, support-free printing, etc. In this paper, we have presented a
framework for the support-free hollowing of 3+2-axis printing. A suite of algorithms including
curved skeleton extraction, print sequence optimization, hollowing generation, and print path
planning is introduced. It is expected that the print efficiency will increase while the residue
artifacts caused by the support structure on the contact surface can be ultimately eradicated. | en_US |
