“…The ANOVA was used to validate the experimental data, and a mathematical model was then developed. [ 92 ] Recently, Mazen et al used a DOE method like Fractional factorial experiments to study the effect of print orientation, layer height, extrusion width, nozzle diameter, and filament temperature on the impact toughness and ultimate tensile strength of the 3D-printed samples. The test results were analyzed with a normal probability plot complimented with ANOVA.…”

Different statistical methods are used in various fields to qualify processes and products, especially in emerging technologies like Additive Manufacturing (AM) or 3D printing. Since several statistical methods are being employed to ensure quality production of the 3D-printed parts, an overview of these methods used in 3D printing for different purposes is presented in this paper. The advantages and challenges, to understanding the importance it brings for design and testing optimization of 3D-printed parts are also discussed. The application of different metrology methods is also summarized to guide future researchers in producing dimensionally-accurate and good-quality 3D-printed parts. This review paper shows that the Taguchi Methodology is the commonly-used statistical tool in optimizing mechanical properties of the 3D-printed parts, followed by Weibull Analysis and Factorial Design. In addition, key areas such as Artificial Intelligence (AI), Machine Learning (ML), Finite Element Analysis (FEA), and Simulation require more research for improved 3D-printed part qualities for specific purposes. Future perspectives are also discussed, including other methods that can help further improve the overall quality of the 3D printing process from designing to manufacturing. Graphical abstract

The aim of this study is to provide first-hand knowledge on additively manufactured structurally graded material (SGM) (polylactic acid / wood-fiber polymer composites) wall. Polylactic acid or polylactide is most effectively used in manufacturing plastic films, bottles, biodegradable medical devices, textile, and agricultural goods. Wood-fiber polymer composites are essentially used in furniture, particleboard, oriented strand board, medium-density fibreboard, plywood, and constructions. SGM is characterized through the change in material composition that is applicable to specific functions. Fabricated SGM exhibited mechanical property such as tensile strength (15.78 ± 0.05 MPa), compressive strength (46.8 ± 2.7 MPa), flexural strength (88.2 ± 0.15 MPa), and impact energy (1.64 ± 0.07 J). Hardness value of SGM is 74.5 shore-D. The coupon studies revealed that SGM possesses better mechanical characteristics than wood-fiber polymer composites and is on par with polylactic acid. The observed morphologies on fracture surface indicate the brittle nature of fracture. This SGM come under advanced materials that are utilized in biomedical, defence, energy, aviation, and nuclear sector, for integrated structural and thermal application.

Additive manufacturing (AM) has been effectively employed in numerous applications due to its enhanced properties such as cost reduction, faster fabrication, and less material wastage. Fused filament fabrication (FFF) method is one of the most prevalent AM process broadly used for fabricating complex polymeric parts. Wood filler dispersed inside thermoplastic matrix (Polylactic Acid-PLA) is termed as Wood-PLA. Wood-PLA is widely employed in building constructions, fencing, and other structural applications. Whereas, Carbon-PLA is a thermoplastic polymer composed of carbon fiber and PLA. Due to its high strength, light weight, and durable properties, it is employed in various industries such as automotive, aerospace, and so on. Bi-materials are multi-functional materials, with unique characteristics at different regions of a part. Due to its unique properties, it is used in different integrated structural engineering applications such as defense, aerospace, energy, and safety gears. Bi-material could be fabricated using FFF through varying the filament after depositing few layers. Fabricated Bi-material exhibited mechanical properties such as tensile strength (16.7 ± 0.08 MPa), compressive strength (51.8 ± 3 MPa), flexural strength (72.1 ± 0.15 MPa), and impact energy (0.910 ± 0.02 J). Hardness value of Bi-material is 76.5 shore-D. The coupon studies revealed that Bi-material possesses better mechanical characteristics than Wood-PLA composites and is on par with Carbon-PLA. This work gives an insight into mechanical behavior of Bi-material (Wood-PLA/Carbon-PLA) under various loads. For microscopic examination (under optical microscopy), the sample was treated using acetone and sandpaper for better revelation of bonding of interface and buckling of layer. The brittle morphologies were observed in the fracture surface of failed sample using scanning electron microscope. The outcome of this study would open up opportunities that help in fabricating integrated structure used in engineering applications.
