NON-PLANAR TOOLPATH FOR LARGE SCALE ADDITIVE MANUFACTURING

The parts produced by additive manufacturing are inherently subjected to discretization effects due their layer-based addition. stair-stepping effect on the surface quality is inevitable for most of techniques and it becomes more dominant regions having small inclinations. influences mechanical properties as well aesthetic perception. Many researchers have been presented several approaches overcome or minimize improve additively manufactured parts. attempts made generally FDM-printed objects, however, there no fewer efforts large-scale (LSAM). Due higher deposition rates (up 50 kg/hrs.) larger nozzle diameters (i.e. bead size) in manufacturing. In this paper, methods mitigate improving reviewed practicing 3D printing discussed. A preliminary experimental study with a non-planar toolpath was carried out results were presented.
