Cost-efficient additive manufacturing: Unraveling the economic dynamics of material Extrusion (MEX) technology

Material Extrusion (MEX), a prevalent form of additive manufacturing (AM), plays a pivotal role in creating three-dimensional objects layer by layer. Investigating MEX printing parameters is crucial, impacting mechanical properties, roughness, material usage, build time, and dimensional accuracy. This study focuses on the economic dimensions of MEX, essential for widespread technology adoption. Understanding of the economic aspects of MEX is essential for maximizing the benefits of this additive manufacturing technology. It allows for the development of efficient, cost-effective, and sustainable manufacturing practices, contributing to its widespread adoption across diverse industries. Employing the Box-Behnken Design (BBD), the research systematically evaluates total costs, amalgamating material and power costs, providing nuanced insights into MEX economic dynamics. Analysis of variance (ANOVA) uncovers the significant impact of printing parameters, with build orientation emerging as pivotal. The optimization process aligns efficiency with cost-effectiveness, validated through robust regression equations. This study, directly relevant to management and business economics, positions itself at the forefront of advancing additive manufacturing, offering practical guidance for economic and operational optimization, particularly in industries adopting MEX technology.
