摘要

The traditional manufacturing process has always struggled with three major issues which include material waste and design restrictions and increased production expenses. The conventional methods of manufacturing fail to produce effective results when they encounter complex geometric shapes because these methods result in material waste and extended time requirements for production. The introduction of Three-Dimensional (3D) and Four-Dimensional (4D) printing technologies brought about new manufacturing processes that allow designers to create better products while reducing waste and improving production capabilities. This research study examines how additive manufacturing affects product development through three design processes which include design for manufacturing and material selection and design for assembly and design for additive manufacturing optimization. The fishbone diagram analysis method helps to establish the relationship between three factors which include mechanical performance and sustainability and cost. The mechanical testing results show that hardness reaches 70.3 and the young modulus exhibits strong negative correlation with layer height, which affects the structural integrity of the material. The process of material selection determines how different materials will perform with respect to durability and flexibility and adaptability. The sustainability analysis conducted in this study showed that additive manufacturing techniques decreased material waste by almost 30% when compared to traditional manufacturing methods, which leads to more environmentally friendly production practices. The research study conducted a cost evaluation which revealed that production expenses decreased by approximately 25% because of 3D and 4D printing technology implementation, thus demonstrating the financial benefits of using these advanced printing methods. The evidence demonstrates that through design for manufacturing and design for additive manufacturing, organizations enhance their operational efficiency, product performance, and environmental sustainability while establishing additive manufacturing as the superior solution compared to traditional methods.
