“…However, the surface roughness of MJF parts, particularly those treated with detailing agent, exhibited significant improvement over SLS counterparts. This disparity in surface quality can be attributed to the differential effects of instant heating, with SLS demonstrating a higher degree of particle melting owing to the intense laser energy [17,70]. Despite the slightly lower mechanical properties observed in MJF parts compared to SLS, the remarkable difference in printing speed, with MJF being nearly ten times faster, underscores the distinct advantages offered by each technology.…”

Linear polyamides, known as nylons, are a class of synthetic polymers with a wide range of applications due to their outstanding properties, such as chemical and thermal resistance or mechanical strength. These polymers have been used in various fields: from common and domestic applications, such as socks and fishing nets, to industrial gears or water purification membranes. By their durability, flexibility and wear resistance nylons have been started to be used in addictive manufacturing technology as a good material choice to get sophisticated devices with precise and complex geometric shapes. Furthermore, the emergence of triboelectric nanogenerators and the development of biomaterials have highlighted the versatility and utility of these materials. In order to enhance the triboelectric performance and the range of applications, nylons show a potential use as tribo-positive materials. Because of the easy control of their shape they can be subsequently integrated into nanogenerators. The use of nylons has also extended into the field of biomaterials, where their biocompatibility, mechanical strength and versatility have paved the way for groundbreaking advances in medical devices as dental implants, catheters and non-absorbable surgical sutures. By means 3D bioprinting nylons have been used to develop scaffolds, joint implants and drug carriers with tailored properties for various biomedical applications. The present paper aims to collect these recently specific applications of nylons by reviewing the literature produced in the last decades, with a special focus on the newer technologies in the field of energy harvesting and biomedicine.

“…However, the existing research has mainly discussed the mechanical properties of 3D-printed structural reinforcement materials at room temperature, and paid little attention to the effect of high-temperature environment on 3d printed lattice-reinforced cement-based composites. Notably, the compressive mechanical properties of PA6 [16,17] lattice structures fabricated using Multi Jet Fusion (MJF) technology [18,19] degrade at elevated temperatures, potentially leading to softening of the polymer material. Herein, we assess the elastic modulus of PA6 under varying temperatures through experimental samples.…”

Research has established that the incorporation of 3D-printed lattice structures in cement substrates enhances the mechanical properties of cementitious materials. However, given that 3D-printing materials, notably polymers, exhibit varying degrees of mechanical performance under high-temperature conditions, their efficacy is compromised. Notably, at temperatures reaching 150 °C, these materials soften and lose their load-bearing capacity, necessitating further investigation into their compressive mechanical behavior in such environments. This study evaluates the compressibility of cement materials reinforced with lattice structures made from polyamide 6 (PA6) across different structural configurations and ambient temperatures, employing ABAQUS for simulation. Six distinct 3D-printed lattice designs with equivalent volume but varying configurations were tested under ambient temperatures of 20 °C, 50 °C, and 100 °C to assess their impact on compressive properties. The findings indicate that heightened ambient temperatures significantly diminish the reinforcing effect of 3D-printed materials on the properties of cement-based composites.
