In low-pressure wax injection molding, cooling time refers to the period during which the molten plastic inside the mold solidifies and cools down to a temperature where it can be safely ejected without deformation. However, cooling efficiency for the mass production of injection-molded wax patterns is crucial. This work aims to investigate the impact of varying surface roughness on the inner walls of the cooling channel on the cooling efficiency of an aluminum-filled epoxy resin rapid tool. It was found that the cooling time for the injection-molded products can be determined by the surface roughness according to the proposed prediction equation. Employing fiber laser processing on high-speed steel rods allows for the creation of microstructures with different surface roughness levels. Results demonstrate a clear link between the surface roughness of cooling channel walls and cooling time for molded wax patterns. Employing an aluminum-filled epoxy resin rapid tool with a surface roughness of 4.9 µm for low-pressure wax injection molding can save time, with a cooling efficiency improvement of approximately 34%. Utilizing an aluminum-filled epoxy resin rapid tool with a surface roughness of 4.9 µm on the inner walls of the cooling channel can save the cooling time by up to approximately 60%. These findings underscore the significant role of cooling channel surface roughness in optimizing injection molding processes for enhanced efficiency.

This study investigates the influence of the addition of glass powder, nozzle size, and infill density on the mechanical properties of 3D-printed polylactic acid (PLA) pieces. To do so, a factorial design of experiments was accomplished. The specimens were tested under tensile and bending conditions. Regression equations were extracted from the maximal strength, strain at maximal strength and modulus, and an analysis of the significance of the terms was carried out. All the factors influence the output variables, independently and in combination. As for the environmental impact, a cradle-to-gate life cycle analysis (LCA) of the printing material with different glass powder additions, including the manufacturing process and transportation of the raw materials, was performed. Additionally, a cost assessment of each alternative was calculated for each case. Since the concurrence of mechanical, environmental, and cost performance is needed to enter a new product in the industry, a multicriteria decision-making analysis was performed to select the best combination. The criteria considered were the material and printing costs and the environmental impact, all normalized with maximal strength. Two different alternatives were found to be the best solution depending on the strength selected. Both of them were printed using a 1.2-mm nozzle with 100% infill and different glass percentages.
