Special Issue Information

Dear Colleagues,

I am pleased to announce this Special Issue on "Additive Manufacturing of Polymer-Based Composites".

Currently, there is an increasing interest in introducing high-performance reinforced polymer-based composite materials for structural applications in key industry sectors, such as aerospace, military, automotive, robotics, and medical. The common feature of these applications is the lightweight design strategy, which provides reduced structural weight while preserving high mechanical performance, less fuel consumption directly related to less carbon emission, and increased design flexibility compared to traditional isotropic materials.

Additive manufacturing (AM) is one of the most promising areas in the fabrication of components from prototypes to functional structures with complex geometries. Compared to conventional methods, AM technologies can shorten the design manufacturing cycle, reduce production costs, and increase competitiveness. Mechanical properties of polymer-based parts fabricated by conventional AM technologies are inherently poor because of the thermoplastic resin used. The development of polymer composites with enhanced mechanical properties addresses previous limitations with the addition of reinforcements, such as particles, fibers, or nanomaterials, into thermoplastic polymers, permitting the fabrication of polymer matrix composites that are characterized by high-performance and excellent functionality. Special attention is focussed on the development of polymer-based composites using engineering thermoplastics such as polycarbonate (PC), polyetheretherketone (PEEK), or polyetherimide (PEI).

This Special Issue is open for submissions and welcomes original research contributions and review articles highlighting recent advances and future directions in the field of Additive Manufacturing of Polymer-Based Composites. In particular, it will publish cutting-edge original research and review papers on the latest advances in new composite systems based on polymeric (both thermoplastic and thermoset), such as novel resin systems, high-temperature thermoplastics, biopolymers, polymer blends or filled polymers, containing particles, nanomaterials, or short/continuous fiber reinforcement. New additive manufacturing technologies based on material extrusion, binder jetting, selective curing/sintering, multi-material printing, and in-situ and post-processing techniques to improve part strength and structure–property relationships are also covered. Contributions that also report on part characterization, the effect of process parameters on mechanical and geometric performance, the application of the produced parts, new developments in CAGD (computer-aided geometric design) to generate optimized trajectories of AM technologies with improved accuracy or post-processing techniques, such as surface finishing and quality assessment, are particularly welcome.

Graphene and its derivatives, such as graphene oxide (GO) or reduced graphene oxide (rGO), due to their properties, have been enjoying great interest for over two decades, particularly in the context of additive manufacturing (AM) applications in recent years. High-impact polystyrene (HIPS) is a polymer used in 3D printing technology due to its high dimensional stability, low cost, and ease of processing. However, the ongoing development of AM creates the need to produce modern feedstock materials with better properties and functionality. This can be achieved by introducing reduced graphene oxide into the polymer matrix. In this study, printable composite filaments were prepared and characterized in terms of morphology and thermal and mechanical properties. Among the obtained HIPS/rGO composites, the filament containing 0.5 wt% of reduced graphene oxide had the best mechanical properties. Its tensile strength increased from 19.84 to 22.45 MPa, for pure HIPS and HIPS-0.5, respectively. Furthermore, when using the HIPS-0.5 filament in the printing process, no clogging of the nozzle was observed, which may indicate good dispersion of the rGO in the polymer matrix. Full article

The range of selective laser sintering (SLS) materials is currently limited, and the available materials are often of high cost. Moreover, the mechanical strength of wood–plastic SLS parts is low, which restricts the application of a SLS technology. A new composite material has been proposed to address these issues, while simultaneously valorizing agricultural and forestry waste. This composite presents several advantages, including reduced pollution associated with waste disposal and reduced CO2 emission with the SLS process in addition to good mechanical strength. In this article, a novel and low-cost Prosopis chilensis/polyethersulfone composite (PCPC) was used as a primary material for SLS. The formability of PCPC with various raw material ratios was investigated via single-layer experiments, while the mechanical properties and dimensional accuracy of the parts produced using the various PCPC ratios were evaluated. Further, the microstructure and particle distribution in the PCPC pieces were examined using scanning electron microscopy. The result showed that the SLS part produced via 10/90 (wt/wt) PCPC exhibited the best mechanical strength and forming quality compared to other ratios and pure polyethersulfone (PES), where bending and tensile strengths of 10.78 and 4.94 MPa were measured. To improve the mechanical strength, post-processing infiltration was used and the PCPC-waxed parts were enhanced to 12.38 MPa and 5.73 MPa for bending and tensile strength. Full article

In this work, the effect of short carbon fibre (CF) on the mechanical and geometric properties of 3D printed polylactic acid (PLA) composite parts processed using the Fused Filament Fabrication (FFF) technique have been analysed. Tensile, flexural and interlaminar shear strength (ILSS) tests were performed to obtain the mechanical performance of the different samples. The surface quality and geometric accuracy of the printed specimens were also evaluated. Finally, Scanning Electron Microscope (SEM) images of the printed samples are analysed. The results revealed that the addition of carbon fibres effectively improved all assessed mechanical properties of PLA-CF composites as compared to the neat PLA. In particular, Flat PLA-CF samples showed an average increase in tensile performance of 47.1% for the tensile strength and 179.9% for the tensile stiffness in comparison to the neat PLA. From the flexural behaviour point of view, Flat PLA-CF samples revealed an increase in average flexural strength and stiffness of 89.75% and 230.95%, respectively in comparison to the neat PLA. Furthermore, PLA-CF samples depicted the best ILSS performance. In general, the use of short carbon fibre as reinforcement did not affect the dimensional accuracy of the PLA-CF samples, and even improved the surface roughness in certain cases, particularly in Flat and On-edge orientations.
