Short Abstract:

Additive manufacturing (AM) is a series of technologies that aims at fabricating solid objects starting from the three-dimensional (3D) model, through the deposition of thin layers of material [1]. The ability to print objects of any shape and size on any type of substrate is an extremely important feature for applications where high in-situ precision is required, such as the fabrication of electronic [2] and microfluidic components [3] or the fabrication of biological tissues in in-situ bioprinting techniques [4]. Thanks to the generation of geometries directly on the required site, the almost total absence of dimensional mismatch between the receiving substrate, and the object to be printed, can be achieved. To correctly plan the printing trajectory onto a non-planar and complex surface a specific operating workflow can be followed starting from the acquisition of the geometry of the printing substrate [5]. Different technologies can be used for this step, obtaining the reconstructed surface where the printing path can be planned. Once the trajectory has been computed, it has to be registered in the operating workspace for proceeding with the material deposition through the desired AM technology [6]. The ability to print onto non-planar surfaces following the curvature of the geometry not only allows to obtain a perfect adhesion on the substrate but also to enhance the mechanical and electrical properties of the printed structure thanks to the deposition of a continuous filament as well as a better aesthetic result.
