“…As a result, a comprehensive analysis of the effects of these process parameters on the mechanical characteristics of the printed parts is essential to establish the optimal settings for FDM. Recently, Yilan et al, [14] conducted an experimental investigation using fused deposition modelling (FDM) to evaluate the impact of three variables, namely infill patterns, infill densities, and printing time, on the tensile strength of PLA+ materials. The experiments involved the 3D printing of test specimens with various infill patterns and densities using FDM technology.…”

Fused deposition modelling (FDM) is a popular 3D printing technique that uses a thermoplastic filament as the build material. In FDM 3D printing, tensile strength can be an issue because the layers of the object are built on top of each other, and if the layers do not adhere properly, the object can be weak and prone to breaking. Typically, this problem is caused by incorrect parameter settings. Hence, this study was then carried out to analyse and improve the printing quality in term of tensile strength of the printed part using the response surface methodology (RSM) and the particle swarm optimization (PSO) method. The effect of four input parameters such as layer height, printing speed, infill density, and print temperature was examined on the tensile strength of polylactic acid (PLA) standard samples ASTM D638-IV. The experimental design was performed using face-centred central composite designs (FCCD). The experimental data were statistically analysed to form a regression model of the tensile strength. This model was used to approximate the actual process. The optimization was performed using desirability analysis from RSM and PSO to search for the optimal parameter for maximum tensile strength. Experimental results showed that PSO outperformed RSM with a 1.52 % reduction in tensile strength. The maximum tensile strength obtained from PSO was about 39.069 MPa with the optimal process parameters of layer height of 0.30 mm, printing speed of 30.17 m/s, infill density of 79.72 %, and print temperature of 205.92 °C.

In this study, eight infill strategies with multiple infilling modes (line, grid, and honeycomb) were used in manufacturing 3D printing of a polylactic acid (PLA) by fused deposition modeling (FDM) process, and the resulting surface topographies and tensile properties were reported. The results showed that the grid/line/grid and honeycomb/line/ honeycomb samples with sandwich structures had the best tensile fracture resistance, which depended directly on the degree of quality of the interlayer. Based on the analysis of the scanning electron microscopy (SEM) of the fracture surface, the improving tensile properties of 3D samples in sandwich structures with line in core were attributed to effective raster, layer bonding, and fewer voids. The finite element (FE) simulation was performed on 3D‐printed parts to predict von Mises stress and tensile strength, which made it possible to reduce the design time to improve the tensile behavior of 3D‐printed structures.

This research explores the use of additive manufacturing, specifically laser 3D printing, to create customized health shoe insoles from natural rubber latex, following ISO/ASTM 52900:2021 standards. By blending natural rubber latex with additives and dispensing the mixture through a syringe nozzle, the process allows for precise extrusion control, while a laser beam cures the latex in real time. Key process parameters—including laser power, beam angle, source distance, nozzle diameter, extrusion rate, and printing speed—were systematically optimized to ensure high precision and efficiency. Additionally, aesthetic properties, such as color and raster angle, were considered to enhance the product’s visual appeal. Mechanical testing, compliant with ISO 37:2024, validated the durability and performance of the printed rubber specimens. Optimal settings of 10 W for laser power, a 45-degree beam angle, 50 mm source distance, 0.85 mm nozzle diameter, 60 mm/s printing speed, and 0.03 mm3/s extrusion rate were determined, while adding 1% v/v blue pigment further improved the material’s ultimate strength. The curing process, maintained between 80 °C and 90 °C to avoid degradation, enabled the production of a US size 7.5 insole in under 24 h. This innovative approach significantly reduces production time and cost, offering a scalable and efficient solution for the manufacturing of customized rubber products through additive manufacturing.
