Parametric Optimization on fused deposition modeling

Abstract

Rapid Prototyping (RP) or additive manufacturing uses layered manufacturing technique, in which layer by layer addition of the
material is done under a controlled environment. The product manufacturing is done directly by using digital manufacturing where in
CAD model of the product is used to process the file and then print the part using a 3D printer. In present work, Fused Deposition
Modeling (FDM) was used to optimize the process parameters involved in the manufacturing the product. These parameters include
build styles. The samples were further tested for their effect on the surface hardness, surface roughness and impact strength; then
their significance during build was studied using paired t test; using Minitab and applied to a particular application. Upon
conclusion, it has been seen that part build styles has no major effect on surface roughness. Minor variations were observed in the
impact strength and surface hardness assessments.
