FDM 3D PRINTING PROCESS PARAMETERS OPTIMIZATION USING TAGUCHI METHOD FOR IMPROVING THE GEAR STRENGTH

In the recent years, 3D printing has become a topic of great interest from both academic and industrial sector through increasing importance Industry 4.0. This technology is based on layer-by-layer melting materials to create three-dimensional object. It also known as additive production, it feasible several different methods such stereolithography, selective laser sintering (SLM, SLS), these are just some examples, but fused decomposition modeling (FDM) most interesting technique.This paper seeks analyze fracture strength (torque) coupled gears made out PLA plastic produced by process. To reduce number experimental measurements, Taguchi L8(27) orthogonal array was used influence factors two level. Investigated were: wall thickness, infill lines, layer height, temperature, cooling speed. Finally, optimization influential according maximum torque preformed, using method too.
