3D Print, Circularity, and Footprints

3D printing is part of the advanced technology that is beneficial in many areas such as construction, packaging, and medicine because it can create objects that can offer a better understanding of specific prototypes or models that you want to study. In addition, it also allows a smaller-scale production with lower costs for companies, so its use represents a comparative advantage and allows creating complex and more personalized designs to offer to its customers. In general, three-dimensional printing represents an efficient form of production that has a wide range of possibilities for its use. However, it is essential to know its impact at the environmental level to manage better and control its use. In the present work, we seek to know the relationship between circularity and three-dimensional impressions and the carbon footprint on the planet. Different sources and comparisons were made, and examples were proposed to explain and describe each previously proposed relationship to meet the research objective. The analysis results concluded that the impact was undoubtedly less than traditional production methods but that there is much room for improvement to reduce further the footprint left by 3D printing, such as a change in the use of materials. On the other hand, it is possible to achieve 3D prints that are circular and sustainable over time by making the necessary efforts. Additionally, the requirements for sustainable production through 3D printing must be not only feasible but also accessible to all to make a real change starting from the smallest companies and individuals that use this technology to the mass productions made by large companies.
