Mixed-Layer-based Adaptive Slicing for Robotic Additive Manufacturing(AM)
Robotic AM is a promising technology that enables the direct fabrication of products with the complex geometry and high performance.However,process planning of slicing has been a challenging issue due to geometric complexity,material property,etc.Most researches focus on slicing 3D CAD models into a set of 2.5D layers possessing a constant or adaptive thickness,or a changeable direction.Besides,curved layer slicing has been proposed to effectively capture sharply varying surface and other finer part details with less layer number(less build time),alleviated stair-step effects(better geometry accuracy)and long length filament(better performance).In order to combine the merits of planar and non-planar layer slicing,this paper reports the concept and implementation of a new mixed-layer-based slicing method for robotic AM,which is based on decomposing-regrouping.It is different from the available similar slicing methods,which mainly focus on finding the optimal slicing directions and applying planar slicing with multi-direction for each sub-volumes as ever.Meanwhile,the requirement for robotic AM equipment possessing multi-modes of printing is emphasized.Generally,this work provides a foundation to design for Additive Manufacture(DFAM),as well as the future development and operation of robotic AM.
