    Sandblasting is a post-processing process that is required to improve the surface due to the layered nature of fused filament fabrication parts. This paper presents preliminary work based on full factorial design of experiment, considering pressure (100 kPa and 700 kPa), time (10 s and 120 s), distance (10 mm and 370 mm) and aluminium oxide abrasive which is 106 µm and 29.5 µm of particles size as the input factors. The effect of the parameters on the surface roughness (Sa) for flat and curve surface, material usage and energy consumption allow were analysed. The result shows that both Sa for flat and Sa curve surface were highly influenced by the abrasive particles size and time with the highest changes of Sa for flat and curve reaches up to 2.825 µm and 6.090 µm respectively. This study provides information on how sandblasting parameters should be selected in improving surface quality and resource usage.

    Fused deposition modelling (FDM) process is one of popular 3D printing technologies, especially on printing polymer materials for a rapid prototyping. The process is well known for its resource saving, with no tooling cost required and minimum energy demand. However, the challenge is that the process performances are highly influenced by selection of parameters. From literature, consideration on material usage and process energy demand in FDM processes is still limited. This study used an L9 Taguchi orthogonal array design in investigating effect of build orientation, printing speed and layer thickness on process energy consumption and total material usage in FDM processes. The p-values from ANOVA analysis revealed that only layer thickness and build orientation had significant effect on the outputs. In minimising material usage, the strategy is to select the correct build orientation to avoid need of support structure. For reducing energy demand, optimum layer thickness needs to be determined by considering other factors such as mechanical properties and surface roughness. This study provides preliminary findings which will benefit FDM users in using resources efficiently. Further studies are required to complement the findings from the aspects of mechanical and physical properties of the printed products.

    Todays, there are various of optimisation methods that have been studied by many researchers in order to find the appropriate combination of processing parameters setting in the injection moulding process. From the previous literatures, the optimisation works have been proven will improve the moulded part quality. In this study, the application of optimisation work to improve warpage of front panel housing has been explored. By selecting cooling time, coolant temperature, packing pressure and melt temperature as the variable parameters, design of experiment (DOE) have been constructed by using the rotatable central composite design (CCD) approach. Response Surface Methodology (RSM) was performed in order to define the optimal processing parameters setting which will optimise the warpage condition. Based on the results, melt temperature is the most significant factor contribute to the warpage condition and warpage have optimised by 47.1% after optimisation. The findings show that the application of optimisation work offers the best quality of moulded part produced.

    The staircase effect describes the overall print surface roughness indicated through the layer by layer of Fused Deposition Modelling (FDM), also known as the Fused Filament Fabrication (FFF) process. Due to the poor surface finish, post-processing can improve the aesthetic effect. The different post-processing procedures for FDM parts are classified as material removal and material addition. This paper reviews four types of material addition methods based on chemical coating post-processing techniques; gap filling, coating spray, plating, and water transfer printing of based on production time, cost and related environmental issues. From the review, spray coating generally is cost-effective and less hazardous to the environment. The paper presents a benchmark between the available material addition techniques as a post-processing step for the FDM printed parts.

    Carbon-fiber-reinforced plastic materials have attracted several applications, including the fused deposition modelling (FDM) process. As a cheaper and more environmentally friendly alternative to its virgin counterpart, the use of milled recycled carbon fiber (rCF) has received much attention. The quality of the feed filament is important to avoid filament breakage and clogged nozzles during the FDM printing process. However, information about the effect of material parameters on the mechanical and physical properties of short rCF-reinforced FDM filament is still limited. This paper presents the effect of fiber loading (10 wt%, 20 wt%, and 30 wt%) and fiber size (63 µm, 75 µm, and 150 µm) on the filament’s tensile properties, surface roughness, microstructure, porosity level, density, and water absorptivity. The results show that the addition of 63 µm fibers at 10 wt% loading can enhance filament tensile properties with minimal surface roughness and porosity level. The addition of rCF increased the density and reduced the material’s water intake. This study also indicates a clear trade-off between the optimized properties. Hence, it is recommended that the optimization of rCF should consider the final application of the product. The findings of this study provide a new manufacturing strategy in utilizing milled rCF in potential 3D printing-based applications.

    Thermal energy storage (TES) systems play a crucial role in sustainable energy management by storing excess energy for later use, improving overall efficiency, reducing emissions, and enhancing grid reliability. Among TES technologies, latent heat thermal energy storage (LHTES) systems are particularly attractive due to their high energy storage capacity and ability to operate at nearly constant temperatures. However, the low thermal conductivity of phase change materials (PCMs) remains a significant challenge, limiting the rate of heat transfer and overall system performance. This study explores the performance of an LHTES system by examining the effects of inlet temperature, mass flow rate, and flow direction, with a particular focus on horizontal flow configurations. The aim is to identify optimal parameter settings that enhance heat transfer efficiency and improve system performance. Using ANSYS Fluent, numerical simulations were conducted with paraffin wax RT82 as the PCM and copper as the triplex tube heat exchanger material. The results showed that an optimized parameter combination reduced the melting time to 232.8 minutes, a 51.44% improvement over the baseline case. These findings highlight the potential for strategic parameter optimization to significantly enhance LHTES efficiency by accelerating PCM melting and improving thermal distribution. This study provides valuable insights into optimizing LHTES system performance, contributing to the development of more effective energy storage solutions that minimize energy losses and improve thermal management.

    A thin-walled tube is an energy absorber device that is commonly used in automotive and locomotive applications. The function of this element is to convert the kinetic energy into other forms of energy during a collision that can minimize injuries to the passengers. Therefore, various studies have been reported previously to improve the thin-walled structure to decrease the damage and provide protection for the vehicle and occupant. This study aims to determine the effects of the cutout on the thin-walled tube when impacted under dynamic axial loading. The effects of sizes, shapes, locations, and the number of cutouts on the energy absorption characteristics have been analyzed by using the validated finite element model. The result indicates that a circular tube with a square cutout shape, larger cutout sizes, and near the top-end of the tube has more energy absorption characteristics. Furthermore, the results of energy absorption (EA), crush force efficiency (CFE), and specific energy absorption (SEA) are highest when applying four cutouts on the surface of the thin-walled tube. Research information provided in this study will serve as a guide in designing the cutout thin-walled tube for crashworthiness enhancements in the future.
