Material Extrusion (MEX) technology, a prominent process in the field of additive manufacturing (AM), has witnessed significant growth in recent years. The continuous quest for enhanced material properties and refined surface quality has led to the exploration of post-processing techniques. In this study, we delve into the ironing process as a vital processing step, focusing on the optimization of its parameters through the application of Design of Experiments (DoE), specifically the Box–Behnken Design (BBD). Through a systematic examination of ironing process parameters, we identified optimal conditions that resulted in a substantial reduction in surface roughness (Ra) by approximately 69%. Moreover, the integration of optimized ironing process parameters led to remarkable improvements in mechanical properties. For instance, the Ultimate Tensile Strength (UTS) saw a substantial improvement of approximately 29%, while the compressive strength (CS) showed an increase of about 25%. The flexural strength (FS) witnessed a notable enhancement of around 35%, and the impact strength (IS) experienced a significant boost of about 162%. The introduction of ironing minimizes voids, enhances layer bonding, and reduces surface irregularities, resulting in components that not only exhibit exceptional mechanical performance but also possess refined aesthetics. This research sheds light on the transformative potential of precision experimentation, post-processing techniques, and statistical methodologies in advancing Material Extrusion technology. The findings offer practical implications for industries requiring high-performance components with structural integrity and aesthetic appeal.

“…Moreover, the manufacturing process of the joint material plays a crucial role, involving heat treatment techniques like quenching and tempering that impact hardness, strength, and toughness [7]- [9]. Surface finish considerations, such as oxidizing and coating, further contribute to appearance, corrosion resistance, frictional characteristics, and protection against environmental factors [10]- [13]. Tightening methods employed in the assembly process also play a significant role in the bolting performance.…”

Bolted joints are used extensively in mechanical engineering due to their reusability, appearance, and strength advantages. In different industrial applications, the separated mechanical components are clamped together during the assembly using a tightening process. Estimating precisely the initially achieved clamping force is a persistent problem for providing a secure and reliable connection for a particular design. However, the nut coefficient is one of the exploratory methods used for this purpose. This paper aims to investigate how the nut coefficient of a bolted joint is influenced by factors such as bolt/nut surface treatment and the presence of lubrication at joint contact surfaces throughout the cyclic joint assembly/disassembly process, serving as a simulation for real-life maintenance operations where the same bolt/nut are reused. Torquing cycles were introduced to bolted joints with two surface finishes and four lubrication conditions. The experiments were conducted on bolts at room temperature according to ISO16047. The nut coefficient was calculated for bolt sizes M6*1, M8*1.5, and M10*1.5. The results were analyzed using the analysis of variance and Taguchi method L32 for estimating the contribution of the different factors on the nut coefficient. It was found that the lubrication was the most significant parameter affecting the nut factor regardless of the bolt size. Also, a case study was conducted to investigate the underlying reasons behind the significance of lubrication in influencing the nut coefficient across different bolt sizes.

Additive manufacturing using fused deposition modelling (FDM) is an affordable and efficient way to produce functional parts and prototypes. However, the FDM-manufactured parts, particularly those made of polylactic acid (PLA), has some drawbacks regarding accuracy and surface finish. To address this, post-processing techniques such as ironing can be applied. However, little is known about the effect of ironing process parameters on surface roughness, and there is a lack of comparative studies on contact and non-contact measurement methods. This study aims to address these gaps by investigating the impact of path speed, ironing spacing, and flow rate on the surface roughness of FDM-produced PLA samples using both contact and non-contact measurement methods. The results show that the ironing process can lead to a significant reduction in surface roughness values, and careful optimization of process parameters can further minimize roughness. The study highlights the advantages and limitations of contact and non-contact methods for surface roughness analysis and provides guidance on selecting the appropriate method for a given application and material.
