“…It is worth noting that, in recent years, AM of polymeric composites (and other types of materials) in tissue engineering has become increasingly popular in scientific societies, especially in the medical field [ 60 , 77 , 78 , 79 , 80 , 81 , 82 , 83 ]. It should be mentioned that the significant parameter of “CLTE” (coefficient of linear thermal expansion) is in the following form [ 80 ],

“…A critical but constraining component of 3D printing design and application is selecting appropriate materials for use as biomaterial inks [ 85 , 86 , 87 , 88 , 89 ]. In research [ 80 ], the inclusion of various forms of biodegradable and biocompatible iron-based metallic reinforcements (stainless steel 316L and monolithic iron) in PLA-based 3D printed scaffolds was studied through analysis of their properties. Stainless steel 316L and iron powders were used as fillers for manufacturing of 3D printed biodegradable PLA, PLA/316L, and PLA/Iron scaffolds for bone tissue engineering applications employing the fused filament fabrication (FFF) process [ 80 ].…”

“…As can be observed in Figure 7 e, the corrosion products have covered the surface in the PLA/Iron scaffold specimen. As shown in Figure 7 b,d, the surface of PLA and PLA/316L scaffold samples remained undamaged even after one month of immersion, showing their higher resistance to degradation than the PLA/Iron specimens [ 80 ]. In the magnified images in Figure 7 b,d, a different corrosion product could be seen between layers, which could be the PLA’s hydrolysis product.…”

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.

Stimuli‐responsive polymers (SRPs) are special types of soft materials, which have been extensively used for developing flexible actuators, soft robots, wearable devices, sensors, self‐expanding structures, and biomedical devices, thanks to their ability to change their shapes and functional properties in response to external stimuli including light, humidity, heat, pH, electric field, solvent, and magnetic field or combinations of two or more of these stimuli. In recent years, additive manufacturing (AM) aka three‐dimensional (3D) printing technology of these SRPs, also known as four‐dimensional (4D) printing, has gained phenomenal attention in different engineering fields, thanks to its unique ability to develop complex, personalized, and innovative structures, which undergo twisting, elongating, swelling, rolling, shrinking, bending, spiraling, and other complex morphological transformations. Herein, an effort has been made to provide insightful information about the AM techniques, type of SRPs, and their applications including, but not limited to tissue engineering, soft robots, bionics, actuators, sensors, construction, and smart textiles. This article also incorporates the current challenges and prospects, hoping to provide an insightful basis for the utilization of this technology in different engineering fields. It is expected that the amalgamation of 3D printing with SRPs would provide unparalleled advantages in different engineering arenas.This article is protected by copyright. All rights reserved.

The corrosion susceptibility and limited mechanical properties of 3D‐printed iron polylactic acid (Ir‐PLA) pose challenges to its application in demanding environments, particularly in marine settings. This study investigates the potential of laser surface texturing (LST) to mitigate corrosion and enhance the mechanical performance of Ir‐PLA 3D printed by fused deposition modeling for saline conditions, in which the fabricated materials are exposed to the seawater environment. A design of experiment approach is employed to systematically evaluate the effects of laser power and scanning speed on surface roughness, contact angle, and tensile test as mechanical properties. Results demonstrate that LST can significantly improve the corrosion resistance of Ir‐PLA, with optimal parameters reducing surface degradation by up to 80%. Furthermore, the laser‐treated samples exhibit a substantial increase in mechanical properties, with tensile strength improving by an average of 25% and ductility increasing by 15%, attributed to the microstructural modifications and patterned surface texture induced by the LST process. The findings highlight the potential of LST as a powerful tool for tailoring the surface characteristics and mechanical behavior of 3D‐printed Ir‐PLA in the seawater‐simulated environment, opening new possibilities for its use in marine applications.
