“…A possible solution for these limitations could be the combination of several different design approaches for the manufacture of the adherends or the use of surface modifications. Some of the studies applied surface modifications which are already in industrial use [ 56 , 62 , 65 , 68 ], while others [ 9 , 50 , 61 , 71 , 72 , 79 ] explored how the printing parameters affect the physical and the mechanical properties of the polymeric adherends. Plasma treatment was assessed as the most effective surface modification for this purpose as it is suitable for use in hollow structures and has the potential of being process integrated.…”

“…Indeed, after heat treatment the PA SLJs reached a maximum shear load of 1.7 kN, 2.5 times lower than monolithic reference value. Kovan et al [71,72] used FFF to manufacture SLJs and butt-joints with PLA substrates to experimentally assess the effect of changing printing orientation and layer height (Figure 13). The authors design strategy is based on the observation that AM parameters affect the component quality, and in particular the surface morphology [73][74][75].…”

This review aims to assess the current modelling and experimental achievements in the design for additive manufacturing of bonded joints, providing a summary of the current state of the art. To limit its scope, the document is focused only on polymeric additive manufacturing processes. As a result, this review paper contains a structured collection of the tailoring methods adopted for additively manufactured adherends and adhesives with the aim of maximizing bonded joint performance. The intent is, setting the state of the art, to produce an overview useful to identify the new opportunities provided by recent progresses in the design for additive manufacturing, additive manufacturing processes and materials’ developments.

3D printing is one of the most portentous technologies for the time being. Recently, 3D printing has progressed remarkably and is expected to proceed in numerous applications, such as automotive, medical, wind turbine, and aerospace applications. 3D printing technology opens the door to enhancing and optimizing several applications. Although of such advancement, there is still a lack of the tribological research investigations in this area. This work is devoted to studying the tribological properties of 3D printed polymers (ABS, PLA, Co-polyester, and PCL) for utilization in a wide range of applications, such as medical, automotive, and various tribological applications. The test specimens were printed using fused deposition modeling (FDM) technology. The tribological characteristics of 3D printed specimens were evaluated using a pin-on-disc tester. Vicker's hardness tester was used to determine the specimens' hardness. Scanning electron microscopy (SEM) with backscattering was used to examine the worn surfaces of samples. Based on the findings of the current investigation, it was discovered that 3D printing technology enhanced the bonding strength and wear resistance of the tested specimens. Furthermore, the 3D-printed polymers (ABS, PLA, Co-polyester, and PCL) produced varying friction coefficient (high and low) values at acceptable wear resistance making them suitable for a wide range of applications. The samples that were printed using PLA and co-polyester had the lowest coefficients of friction (0.3) while the samples that were printed using ABS and PCL had the greatest coefficients of friction (0.4) and (0.39) respectively.

“…One of the earliest investigations on comparing the joining techniques for AM parts was carried out by Espalin et al, 44 wherein various methods were sorted as per effectiveness of the strength including hot air welding, ultrasonic spot welding, solvent, and adhesive bonding. Numerous researchers including Bergonzi et al, 28 Frascio et al, 45 and Kovan et al 46,47 attempted to investigate the effect of FDM printing parameters including extruder temperature, raster angle, printing speed, layer thicknesses, and print orientation on the strength of the adhesively bonded parts. A remarkable finding was that improvement in the strength could be obtained by simply setting the FDM printers parameters properly.…”

Three-dimensional printing (3D), a vital technological pillar of industry 4.0 suffers from an important bed size limitation, wherein it cannot print any part larger than its bed size. Unfortunately, research in this domain has not kept pace with the other limitations hindering the acceptability of fused deposition modeling (FDM)-3D printers. This paper investigates the adhesive joining of dissimilar 3D-printed parts made from usually preferred materials (Acrylonitrile Butadiene Styrene (ABS), Polylactic Acid (PLA)) having different geometric joint designs (lap, scarf, stepped) employing diverse adhesives (epoxy, cyanoacrylate, polyurathane-based) subjected to different surface treatments (sanding, vapor, plasma). The aim is two-fold: to enhance the joint strength making adhesive bonding a suitable solution for complex structural application, as well as to overcome the bed size limitation of commercially available 3D printers. The individual and combined effect of the parameters, prediction, and validation for tensile strength were realized by statistical tools (DOE and ANOVA). The results revealed the significance of the process parameters in the following order: material type, joint configuration, adhesive types, and surface pre-treatments. The preferred material turned out to be ABS + ABS, with stepped configuration, subjected to plasma treatment and bonded with Loctite adhesives giving a strong improvement in terms of performance. Finally, the model summary with R2 value of 95.6% implied that the experimentation was successful and could be easily reproduced on an industrial scale helping to attain high strength-less weight components even with smaller FDM-3D printers.
