“…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.

“…In other studies, the influence of the laminate sequence, the type and density of reinforcement and fill patterns on the tensile, compressive and bending behaviour of printed components were analysed [22][23][24][25]. There are also studies that analysed other phenomena such as creep [26], fatigue [27], quasi-static indentation [16], impact resistance [28] and hygromechanical behaviour [17]. In these studies it was observed that the mechanical behaviour of the printed materials was highly conditioned by process-induced defects.…”

Taking advantage of an extended design and manufacturing space for composites, the technology of Fused Filament Fabrication (FFF) of continuous fibre-reinforced thermoplastics shows great potential for the production of the next generation of lightweight structural parts. This novel process is very much under development, and knowledge of the mechanical behaviour of the resulting 3D-printed materials is still limited. In this work, the intra-and inter-laminar behaviours of carbon fibre/polyamide printed laminates were extensively characterised to determine ply elastic and strength properties, as well as interface strength and fracture characteristics. Moreover, the effects of eventual production defects on these properties were analysed, putting in evidence some of the present shortcomings of the FFF process. Such defects include non-homogeneous fibre distribution, large amounts of intra-and interlaminar voids, and weak interlayer bonding, which are likely to be due to insufficient thermo-mechanical consolidation of the material during the FFF process, and have significant influence on the matrix-dominated mechanical properties. As a result, the transverse and interlaminar properties were found to be lower than those obtained through Hot Compression Moulding of an equivalent material. Besides highlighting possible process improvements, the mechanical characterisation carried out in this work promises a significant

“…Additive manufacturing can in fact extend the life of products by fostering customized product part repairing, waste recovering, and recycling [9,10]. Several research studies have been conducted so far for the development of additively manufactured polymer composites [11][12][13]. Very recently, the possibility of reusing mechanically recycled GFRPs in a curable matrix was presented in our previous works [14].…”

Additive Re-Manufacturing of Mechanically Recycled End-of-Life Glass Fiber-Reinforced Polymers for Value-Added Circular Design

Despite the large use of composites for industrial applications, their end-of-life management is still an open issue for manufacturing, especially in the wind energy sector. Additive manufacturing technology has been emerging as a solution, enhancing circular economy models, and using recycled composites for glass fiber-reinforced polymers is spreading as a new additive manufacturing trend. Nevertheless, their mechanical properties are still not comparable to pristine materials. The purpose of this paper is to examine the additive re-manufacturing of end-of-life glass fiber composites with mechanical performances that are comparable to virgin glass fiber-reinforced materials. Through a systematic characterization of the recyclate, requirements of the filler for the liquid deposition modeling process were identified. Printability and material surface quality of different formulations were analyzed using a low-cost modified 3D printer. Two hypothetical design concepts were also manufactured to validate the field of application. Furthermore, an understanding of the mechanical behavior was accomplished by means of tensile tests, and the results were compared with a benchmark formulation with virgin glass fibers. Mechanically recycled glass fibers show the capability to substitute pristine fillers, unlocking their use for new fields of application.
