Fusion deposition modelling (FDM) is a widely used polymer additive manufacturing method for producing complex parts, yet end-user suitability depends strongly on selected process settings. This study investigates how layer thickness, filler density, and printing speed influence the tensile properties of carbon-fiber-reinforced polylactic acid (PLA) samples. Taguchi’s experimental design approach is adopted to reduce the number of experiments while locating optimal conditions. Test results are used to determine ideal parameters for tensile strength-related properties and modulus of elasticity, supporting lightweight parts with rapid stress performance.

India 1,2 . | ABSTRACT: | | --- | | The most common method for swiftly creating complex parts using polymer additive manufacturing is fusion deposition modelling (FDM), which is gaining popularity in a variety of technical applications. Well selected process settings have a major impact on the mechanical properties of 3D printed objects. The process known as additive manufacturing (AM) was initially developed as a quick prototyping tool for design visualization and validation. FDM has encountered difficulties with making parts that end users can use. In this study, we examine the impact of layer thickness, filler density, and printing speed on the tensile properties of polylactic acid (PLA) samples. Taguchi's technique for experiment design is applied to decrease the number of experiments and identify the perfect conditions for the best mechanical properties, low weight, and rapid stress. The ideal process parameters for tear strength and modulus of elasticity were determined based on testing findings. | 1. Introduction: AM or 3D printing uses layers of materials and digital information to build structures. Because to growing global competition and changing consumer expectations, including a higher demand for customised items and shorter production times, AM has emerged in many technical and industrial industries as a feasible option to satisfy the aforementioned criteria. Environmental effects, material qualities, quality, energy usage , and recyclable content are among the selection criteria for each AM application. Each AM application has its own functionality indices and weights that represent various design goals. By generating parts in a single cycle, additive manufacturing (AM) technology has the potential to drastically reduce the waste of raw materials. Despite the fact that AM is an effective process, issues with material and printing equipment compatibility have made it challenging to implement on a large scale. The input process parameters have a big impact on the quality of the AM components. FDM is one of the most widely used and promising technologies because of its connection to desktop 3D printers, even though there are many commercially available AM processes for the production of parts, including Inkjet modelling, fused deposition modelling (FDM), stereo lithography (SLA), sheet lamination (LOM), etc. The FDM technology, which expedites machining, allows for the creation of complex forms out of lightweight materials. FDM, unlike many other AM techniques, uses a die to extrude a thermoplastic material that is semi-solid and uses a range of lasers, powders, and resins. A variety of thermoplastic polymer materials are melted using the FDM technique, as shown in Figure 1, and are then deposited using a die onto a build platform. Acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) are materials used to construct three-dimensional constructions (section) . Layers of molten filament are placed to the build platform in accordance with the part's design after being delivered by feed rollers shaped like the required material. Recycling is made possible by FDM technology, which also helps to reduce waste and improve the environment. Figure 1 depicts a schematic of the manufacturing procedure for FDM parts. According to several authors, the build orientation significantly affects how durable FDM components are. AM recommended using an optimisation procedure to figure out the elastic modulus of th
