This paper presents a new method for filling the arbitrarily shaped closed contours with identical circles, as a part of the slicing software for droplet-generating 3D printers. 3D printers, as a part of Rapid prototyping technology, offer engineers and designers the possibility of producing models and prototypes layer wise in a fast way and directly from a CAD model. A Rapid prototyping process can...
This paper presents an evaluation of an algorithm that optimises the infills of the geometries that contain at least one pointed end. Computation of the infills, as a part of path planning, falls within the slicing procedure, which in turn is a standard process step in creating a 3D part via rapid prototyping techniques. The computation of the infill trajectories were conducted according to its final...
In this paper a new slicing method for filling an arbitrary polygon with 3D-balls for a 3D plastic droplet generation process is presented. The work principle of the 3D plastic droplet generation is to squeeze the plastic material through a nozzle, out of which small hardened balls are formed and based on the contour and infill algorithm the 3D objects filled with plastic droplets are layer-wise created...
