The energy efficiency of material extrusion additive manufacturing has a significant impact on the economics and environmental footprint of the process. Control parameters that ensure 3D-printed functional products of premium quality and mechanical strength are an established market-driven requirement. To accomplish multiple objectives is challenging, especially for multi-purpose industrial polymers, such as the Poly[methyl methacrylate]. The current paper explores the contribution of six generic control factors (infill density, raster deposition angle, nozzle temperature, print speed, layer thickness, and bed temperature) to the energy performance of Poly[methyl methacrylate] over its mechanical performance. A five-level L25 Taguchi orthogonal array was composed, with five replicas, involving 135 experiments. The 3D printing time and the electrical consumption were documented with the stopwatch approach. The tensile strength, modulus, and toughness were experimentally obtained. The raster deposition angle and the printing speed were the first and second most influential control parameters on tensile strength. Layer thickness and printing speed were the corresponding ones for the energy consumption. Quadratic regression model equations for each response metric over the six control parameters were compiled and validated. Thus, the best compromise between energy efficiency and mechanical strength is achievable, and a tool creates significant value for engineering applications.

“…References [5,13,[16][17][18] reveal that the lower thickness of the deposited layers will improve the ultimate tensile strength of samples. In this study, although the maximum value was highlighted for the layer thickness of 0.15 mm, higher elongation at break is observed in the specimens with a layer thickness of 0.2 mm.…”

The specimens (Figure 2) used in this study to assess dimensional accuracy, repeatability and mechanical properties are modeled based on ASTM D638, Type IV standards for tensile testing of plastic [13,14]. The specimen model was designed using Autodesk Inventor software, transformed into STL format, and the G-code was made using the 3D printer software: Idea Maker.…”

FFF (Fused Filament Fabrication) prototyping method is mostly used in the fabrication of 3D complex geometric shapes. Layer by layer deposition technology offers a wide range of shapes for plastic parts. The mechanical characteristics of the manufactured parts depends on the plastic material used and the FFF printing parameters. The studies conducted in this paper show the influence of the FFF parameters on the tensile properties of ABS (Acrylonitrile Butadiene Styrene). The results indicate a considerable effect of infill percentage on tensile properties.

“…Two important factors affect the tensile strength of the printed part; the voids and gaps inside the material. These defects make the produced part highly anisotropic (Weake et al , 2020). The adhesion between the layers and filaments is formed by thermal fusion.…”

Purpose The purpose of this paper is to analyze the effect of printing parameters on the mechanical properties of standard dog bone specimens manufactured by fused deposition modeling. Design/methodology/approach Polylactic acid (PLA) specimens were printed and tested according to the ASTM standard. The effect of five important printing parameters, layer height, raster angle, printing speed, nozzle temperature and nozzle diameter, was examined on ultimate tensile strength (UTS), elongation and apparent density. Five levels were attended for each parameter, and a high number of required experiments were reduced by applying the L25 Taguchi design of the experiment. Findings The effect of each parameter on outputs and optimal values for maximum tensile strength were determined. The most influential parameter is the raster angle of 64.96%. Nozzle temperature has a low effect of 1.76%, but nozzle diameter contribution is 9.77%. The experiment results are validated by analysis of variance analysis, and the optimal predicted level for parameters is 90° raster angle, 0.2 mm layer height, 100 mm/s printing speed, 200°C nozzle temperature and 0.8 mm nozzle diameter. The maximum UTS observed is 48.70 MPa for 0.8 mm nozzle diameter, whereas the minimum is 18.49 for 0.2 mm nozzle diameter. Originality/value This paper is a very extensive experimental research report on the effect of the parameters for the tensile property of 3D printed PLA specimens by the Taguchi method. The documented results can be further developed for an optimization model to obtain a desired mechanical property with less variation and uncertainty in a product.
