“…With the incorporation of a variety of continuous fibres including natural and synthetic fibres, studies to analyse the impact of infill density, fibre orientation and type of fibre on mechanical performances of FDM printed composites have been conducted by both experimental and modelling methods [ 175 , 176 , 177 , 178 , 179 , 180 ]. Mohammadizadeh et al [ 181 ] performed an investigation to study the effect of temperature, fibre type, infill density and fibre orientation on continuous carbon, glass and Kevlar fibre reinforcement composites printed on the Mark Two printer. The highest tensile strength was exhibited by the CF specimen with the combination of both isotropic infill and two concentric rings.…”

Fused deposition modelling (FDM) is one of the fastest-growing additive manufacturing methods used in printing fibre-reinforced composites (FRC). The performances of the resulting printed parts are limited compared to those by other manufacturing methods due to their inherent defects. Hence, the effort to develop treatment methods to overcome these drawbacks has accelerated during the past few years. The main focus of this study is to review the impact of those defects on the mechanical performance of FRC and therefore to discuss the available treatment methods to eliminate or minimize them in order to enhance the functional properties of the printed parts. As FRC is a combination of polymer matrix material and continuous or short reinforcing fibres, this review will thoroughly discuss both thermoplastic polymers and FRCs printed via FDM technology, including the effect of printing parameters such as layer thickness, infill pattern, raster angle and fibre orientation. The most common defects on printed parts, in particular, the void formation, surface roughness and poor bonding between fibre and matrix, are explored. An inclusive discussion on the effectiveness of chemical, laser, heat and ultrasound treatments to minimize these drawbacks is provided by this review.

“…Dickson et al [19] compared different types of fibers (glass, carbon, and Kevlar), testing tensile and flexural specimens having a unidirectional arrangement of the fibers, by varying the number of built layers. Materials similar to the latter were also evaluated for creep and fatigue by Mohammadizadeh et al [20]. The flexure behavior of 3D-printed specimens reinforced with continuous glass or carbon fibers, arranged unidirectionally, was then studied by Goh et al [21].…”

Recent years have seen the wide diffusion of composite materials in many manufacturing fields and the rapid evolution of additive manufacturing. Lately, these technologies have been combined practically allowing the fabrication of continuous-fiber reinforced polymer parts via 3D-printing. This topic is gaining attention both in the research community and among industrial users. Because of their novelty, such manufacturing methods are, however, still not thoroughly understood, and their performance limits have not yet been fully characterized. This study aims at analyzing the mechanical resistance of components made with continuous carbon fiber (CCF) thermoplastic materials by means of fused filament fabrication (FFF), focusing on the influence of the fiber orientation on such properties. In particular, both the tensile and the bending characteristics are evaluated according to the relative test standards, in specimens with both unidirectional and mixed-isotropic configurations. The experimental findings are compared with a set of reference specimens made with a base polymer filled with chopped “short” carbon fibers, allowing one to appreciate the advantages or limitations of the different fiber arrangements.

“…AM systems are categorized into four main groups of metals [4], polymers [5,6], ceramics [7], and composite systems [8][9][10][11]. In the last two decades, metal AM has emerged as an important commercial manufacturing technology [12] with a wide range of applications in the automotive, aerospace, oil, and gas, and marine industries, and the technology has attracted significant attention [3,13].…”

Metal additive manufacturing (AM) has gained much attention in recent years due to its advantages including geometric freedom and design complexity, appropriate for a wide range of potential industrial applications. However, conventional metal AM methods have high-cost barriers due to the initial cost of the capital equipment, support, and maintenance, etc. This study presents a low-cost metal material extrusion technology as a prospective alternative to the production of metallic parts in additive manufacturing. The filaments used consist of copper, bronze, stainless steel, high carbon iron, and aluminum powders in a polylactic acid matrix. Using the proposed fabrication technology, test specimens were built by extruding metal/polymer composite filaments, which were then sintered in an open-air furnace to produce solid metallic parts. In this research, the mechanical and thermal properties of the built parts are examined using tensile tests, thermogravimetric, thermomechanical and microstructural analysis.
