“…Arun K. and others in their work [43] described the possibility of using copper coatings on polylactide parts produced in the MEP process used in the electrotechnical industry. Tests confirmed the increase in corrosion resistance of copper electrodeposited coatings in sea water, as well as the increase in Vickers hardness.…”

Appropriate selection of polymeric materials enables their wide application not only in machine construction elements, suspension and interior equipment of vehicles. Simultaneously with the development of new polymer materials, the processes of their processing developed. This also applies to incremental technologies. Rapid prototyping methods using 3D printers are largely based on various types of polymer materials. Currently, 3D printing is a well-known technique for producing functional elements, especially the Melt Extrusion Polymers (MEP) method, which is the oldest of the known techniques of spatial production. The main reason of the technology is designing and then manufacturing parts for many fields, including engineering, medicine, as well as the automotive and aviation industries. The article is a review of the literature on the use of composites based on thermoplastic polymers to develop new polymer materials used for 3D printing by MEP.

The production of complex structures out of a variety of materials has undergone a revolution due to the rapid development of additive manufacturing (AM) technology. Initially confined to applications such as magnetic actuators and two‐dimensional electric or electronic circuits, the convergence of 3D printing and metallization methods has emerged as a revolutionary approach. This synergy facilitates the creation of functional and customizable metal‐polymer hybrid structures characterized by high strength, lightweight properties, intricate geometric designs, and superior surface finish. These structures also exhibit enhanced electrical and thermal conductivity, as well as optical reflectivity. This paper reviews techniques to improve the effectiveness of 3D‐printed polymer antennas and structures by using various techniques of metallization. The metallization processes are examined, and a classification based on the materials employed is presented to facilitate comparisons that highlight the optimal utilization of materials for the fabrication of 3D‐printed polymer structures. The main emphasis here is on the effectiveness of different processes in terms of deposition, bonding strength, electrical conductivity, and various characteristics of metallic coatings developed on polymers. This review contributes an in‐depth analysis of the latest developments in 3D printing and metallization techniques specifically applied to polymer antennas and structures. The exploration extends to potential applications, challenges encountered, and future prospects within this dynamic field. As AM and metallization continue to evolve, this study aims to provide a comprehensive understanding of the state‐of‐the‐art methodologies and their implications for the future of polymer‐based structures and antennas.

“…The two are now well-known thermoplastic filaments used as feedstock for FDM 3D printing [23]. However, PLA appears in few studies in relation to POP, partly due to challenges associated with its low glass transition temperature and high sensitivity to hydrolysis reaction, which can lead to deformation and degradation of parts during the POP process [2,3,[24][25][26][27][28]. Thus, developing a suitable POP process and optimizing appropriate POP parameters for PLA are critical challenges for researchers in the field.…”

With environmental awareness in societies, bioplastics continue to receive increasing attention and utilization rate. Polylactic acid (PLA) is one of the most important biopolymers in the market today, owing to its high strength and relative ease of forming. Unlike the common structural, fossil fuel-based plastics, such as Acrylonitrile-Butadiene-Styrene (ABS), the surface of PLA cannot be readily metallized in preparation for electroplating using the conventional plating-on-plastic (POP) process. This partially limits the wider use of the material for functional and decorative applications. In this research study, we systematically explored three strategies for metallizing the surface of PLA, namely, (A) chemical etching and palladium activation technique, (B) polyelectrolyte multilayers (PEMs) and Ag nanoparticle deposition technique, and (C) Ag conductive painting technique. PLA samples, prepared by Fused Deposition Modelling (FDM) 3D-printing technique, were metallized by various techniques followed by electroless deposition and electroplating of copper layers. The study was performed comparatively with respect to the ABS surface. The samples microstructures, chemical distributions, and plating characteristics were assessed with optical and scanning electron microscopy. The adhesion of the metallic coatings was analyzed using scratch test and tape test. Although uniform deposition of copper layers on PLA surfaces could be achieved using all three metallizing methods under investigation, the three methods were found to provide different degrees of benefits with respect to deposition rate, surface uniformity, and process simplicity.
