Abstract The present study is aimed at determining the local density of components made by fused deposition modeling (FDM) through non-destructive indentation tests. An experimental campaign was performed to assess such a relationship. Specimens were varying amount material flow and direction deposition. specimen’s dimension weight measured determine average density. internal porosity due uncom...

The widespread use of additive manufacturing (AM) has been extensively progressed in the past decade due to convenience provided by AM rapid and reliable part production. Fused deposition modeling (FDM) witnessed even faster growth application as its equipment is environmentally friendly easily adaptable. This increased FDM manufacture prototypes finished parts accompanied concerns that 3D prin...

Surface quality is one of the limiting aspects additive manufacturing (AM). This paper presents findings from a study to optimize Fused Deposition Modeling (FDM) process parameters improve surface roughness printed test specimen. Taguchi 3⁴ and L9 orthogonal array were used design experiment. Samples models same size fabricated with an open source FDM printer using acrylonitrile butadiene styre...
