Experimental Investigation of Build Time During ABS Filament Material Extrusion Process

Filament material extrusion (f-ME) is a widespread process for thermoplastic prototypes or final parts, which is characterized as an additive manufacturing process, i.e., adding materials in layers utilizing the material extrusion mechanism. Build time is significant in this process and defines the productivity rates, energy and material consumption. In this work, is presented the study about the influence of deposition angle, layer thickness, infill ratio and infill pattern on process build time experimentally. The Taguchi experimental design was selected, and nine ABS (Acrylonitrile—Butadiene—Styrene) thermoplastics were 3D printed following the L9 experimental orthogonal array. The measured build time was analyzed by using analysis of means (ANOM) and analysis of variance (ANOVA) techniques, followed by a validation experiment in optimal parameter combination. This research serves as a valuable source and comprehensive guide to 3D printing parameters selection in the filament ME process.
