“…As a result, the drive to improve treatment options to address these disadvantages has intensified in recent years. Other research [ 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 ] looked at the effect of the defects on the mechanical efficiency of FRC and subsequently discussed treatment options for removing or minimizing them to improve the functional properties of the fabricated parts. Since FRCs are made up of a polymeric matrix and a short or continuous fiber reinforcement, the analysis will go through the effects of AM parameters such as infill pattern, layer thickness, raster angle, and fiber orientation on both thermoplastic polymers and FRCs printed using FDM technology.…”

In this research article, a mini-review study is performed on the additive manufacturing (AM) of the polymeric matrix composites (PMCs) and nanocomposites. In this regard, some methods for manufacturing and important and applied results are briefly introduced and presented. AM of polymeric matrix composites and nanocomposites has attracted great attention and is emerging as it can make extensively customized parts with appreciably modified and improved mechanical properties compared to the unreinforced polymer materials. However, some matters must be addressed containing reduced bonding of reinforcement and matrix, the slip between reinforcement and matrix, lower creep strength, void configurations, high-speed crack propagation, obstruction because of filler inclusion, enhanced curing time, simulation and modeling, and the cost of manufacturing. In this review, some selected and significant results regarding AM or three-dimensional (3D) printing of polymeric matrix composites and nanocomposites are summarized and discuss. In addition, this article discusses the difficulties in preparing composite feedstock filaments and printing issues with nanocomposites and short and continuous fiber composites. It is discussed how to print various thermoplastic composites ranging from amorphous to crystalline polymers. In addition, the analytical and numerical models used for simulating AM, including the Fused deposition modeling (FDM) printing process and estimating the mechanical properties of printed parts, are explained in detail. Particle, fiber, and nanomaterial-reinforced polymer composites are highlighted for their performance. Finally, key limitations are identified in order to stimulate further 3D printing research in the future.

“…However, it was difficult to achieve sufficient conductivity using only hydrogel and PEDOT:PSS, and although the conductivity was improved by adding a small amount of highly conductive carbon nanotubes to the light-curing resin that formed the hydrogel, the conductivity was only 0.425 S cm -1 . As an alternative method to fabricate conductive 3D wiring using PEDOT precursors, Yamada et al impregnated the EDOT dimer in a Nafion film and succeeded in obtaining a high conductivity of 3500 S cm -1 ; however, their method is limited to inner Nafion film [18].…”

Recently, flexible devices using intrinsically conductive polymers, particularly poly(3,4-ethylenedioxythiophene) (PEDOT), have been extensively investigated. However, most flexible wiring fabrication methods using PEDOT are limited to two-dimensional (2D) fabrication. In this study, we fabricated three-dimensional (3D) wiring using the highly precise 3D printing method of stereolithography. Although several PEDOT fabrication methods using 3D printing systems have been studied, few have simultaneously achieved both high conductivity and precise accuracy. In this study, we review the post-fabrication process, particularly the doping agent. Consequently, we successfully fabricated wiring with a conductivity of 16 S cm−1. Furthermore, flexible wiring was demonstrated by modeling the fabricated wiring on a polyimide film with surface treatment and creating a three-dimensional fabrication object.

Resins for 3D printing usually do not present suitable photoluminescence for application in optoelectronic devices. Herein, a conjugated polymer (PFeBSe) with luminescent and high refraction index properties was synthesized and used to modify an acrylate-based resin. This PFeBSe copolymer presents an ester-based side group that enhances the compatibility with the acrylate resin, resulting in a homogeneous polymeric blend. Further, the modified resin was employed with the 3D digital light processing (DLP) technique to produce luminescent guiding structures with a tailored refraction index. To maintain the processing parameters of the acrylate resin, the blending with the conjugated polymer was kept at a low concentration in the range of 5% to 15% (v/v). The blending changed the refraction index of the pristine acrylate from 1.49 to 1.51 (5% v/v) and 1.56 (15% v/v), respectively. Moreover, the resulting structures present a low extinction coefficient at the wavelength region above 600 nm. These characteristics enable the fabrication of structures with controllable forms and dimensions that can be used in the design of advanced sensors and optoelectronic devices.
