“…On the other side, as the infill ratio increases, the distortion values decrease owing to the lowering pore level. Similar findings in which the mechanical properties of ceramic fiber-filled polymer composites produced with FDM improved due to the increasing fill rate levels were emphasized in the study by Öteyaka et al [67].…”

It is known that products made of polymer materials or especially polymer materials with glass fiber and carbon fiber are used in many different areas such as automotive, aerospace, and defense. At this point, studies in the literature have gained momentum due to the combination of fiber-reinforced polymer materials emerging as a result of technological developments and industrial demands, and the fused deposition modeling (FDM) method providing the production of parts in desired sizes and complexity. Residual stresses and distortions occurring in polymer-based composite parts produced with FDM are among the problems that should be minimized. In this study, the influences of fiber ratio (%10, %15, and %20), infill rate (%20, %50, and %80), and infill pattern (line, honeycomb, and triangle) on the residual stresses and warpages generating in impact test specimens produced from glass fiber reinforced ABS filaments by fused deposition modeling were tried to be determined with the Digimat 2021 program. As a result of the findings, it was determined that the distortion values decreased and the thermal residual stress values went up with the increase in fiber ratio and infill rate. In addition, it can be reported that the distortions that bring out as a result of the separation of the produced parts from the production platform are caused by the high deformations condensing at the lower corner points of the parts.

“…That study states that the addition of 7.5 wt.% of carbon fiber resulted in an ultimate tensile strength (UTS) of 42 MPa, while 15 wt.% of carbon fiber decreased the UTS to 35 MPa. 35 Another reason could be that the strength of the parts produced from carbon fiber filaments is strongly influenced by the 3d-printing parameters. 37,38 Since all filaments in this study were fused according to the same parameters for comparison purposes, the optimum value for carbon fiber may not have been achieved.…”

The fused deposition modeling (FDM) technique which is one of the 3D printing technologies was used to produce a centrifugal pump impeller. The fabrication and investigation of the impeller were preferred because of its complex geometry and the difficulties encountered in its production. The most commonly used ABS, HIPS, PLA, and carbon fiber filaments were preferred to compare and determine the most suitable material for the production of the impellers. Firstly, mechanical test specimens from four different materials were printed in the 3D printer according to standards. Then the tensile tests and quasi-static punch shear tests (QS-PST) were applied to determine the mechanical properties of the 3D printed parts. Also, the mechanical tests were repeated to some specimen with the different fillings to define the optimum fill rates. Secondly, the impellers were fabricated from four materials by using the 3D printer in determined fill rates. Then, these impellers were mounted in the actual pump system, and pump performance tests were performed. In the pump performance tests, the head, pump efficiency, and electric power parameters were measured against the flow rate for each impeller. Finally, the mechanical properties and pump performance of the impellers compared with the GG25 cast iron impeller which is produced by traditional technique. As a result, PLA was selected as the most appropriate material for the production of the impellers. Furthermore, PLA showed superior performance compared to others when price, production time, and product weight parameters were considered.

“…The mechanical properties of the polymer composites are reinforcement type, content, and printing parameters. The printing parameters like layer height, raster angle, infill density, printing speed, infill pattern, and bed temperature [ 23,47–83 ] are extensively investigated by researchers to optimize the mechanical properties, as shown in Table 2.…”

“…A comparison was performed for the carbon fiber PLA composite specimen, which depicted that with the increase in the infill ratio, the specimens' tensile properties increased as the filament width and the area of pore/gap decreased. [ 58 ] In stainless steel reinforced ABS, up to 15 wt% tensile strength increased, then reduced, as, at high loading, more defects are present, affecting the part's mechanical stability. [ 51 ] Sodeifian et al [ 72 ] conducted a study where they reinforced PP composite filaments with 30% glass fiber reinforcement with POE‐g‐MA at different weight percentages (10, 20, and 30 wt%) to increase the flexibility of the filaments.…”

The additive manufacturing (AM) technology can manufacture complex parts with considerable improvements in lead times and lower material wastages. It has enabled technological advances across many domains, from space to medical devices. The polymer composites fabricated through AM have tremendous advantages over conventional polymers in terms of mechanical performance and are, therefore, better suited for producing functional parts and assemblies. However, AM of polymer composites still presents several technological obstacles that prevent their full commercial utilization. These challenges include limited combinations of matrix and reinforcements, a requirement for hardware modification of existing machines, and challenges in mechanical characterization. This article attempts to comprehensively review the fundamentals and features of contemporary additively manufactured polymer composites (AMPCs) and examines current cutting‐edge research and development. This review highlights the gaps in the mechanical characterization of polymer composites fabricated through various technologies like material extrusion, vat‐photopolymerization, binder jetting, material jetting, powder bed fusion, and sheet lamination. There is a need to fill the identified research gaps to make AMPCs more appealing for widespread industrial use for advanced applications.
