Feasibility of Circular Economy in 3D PrintingD printing is a great technology because it can become a processing technology, not a typical subtraction process in most manufacturing environments. In this article, we will discuss the impact of 3D printing technology and other related initiatives, which will help us better understand the circular economy and 3D printing.(Cycle of circular economy)When we adopt a firm attitude towards solving the problem of waste, waste is not a problem. Scientists have been studying this series of circular economy, initially outlining various ideals and thinking processes, not only focusing on 3D printing, but also turning to a more cyclical economy before using a technology to build this ideal.In terms of overall waste reduction, the technology of adding materials is amazing. When a product-based technology system is established, the ability of sustainable development is stronger as people print projects according to their needs. In subtraction manufacturing, products are extracted from larger materials. After the initial product is created, this may render many components unusable. This can then cause product residues to be discarded or further recycled. It takes a lot of time to do this, and it becomes an efficiency problem within the framework of circular economy. This process is not only a waste of time, but now other factors must be calculated, such as the transport of waste residues and the amount of energy consumed. There are many factors that have not been further analyzed in the traditional manufacturing process.Experiments in the field of add-on manufacturing have matured because it is a concept and method of natural destructiveness. A very important ideological process in this field is currently concerned with material development. Material development is critical in terms of sustainability. Depending on the structure of the polymer, we can make materials with specific properties that we like. This can make materials easier to recycle, and they have natural biodegradable properties. It is still important to build a larger living infrastructure, which will lead people to truly understand their choices and how they affect the larger world. Although 3D printing is inherently helpful in preventing overproduction, there is still a lack of awareness of its production and consumption rate. Many people have failed in prototyping standards. This also leads to a larger amount of waste.(Image results of material development and add-on manufacturing)In terms of sustainability, add-on manufacturing is superior to traditional methods. If we don't engage in infrastructure, we still have to realize that we are losing money on sustainability. This includes thinking infrastructure and methodological infrastructure. We must use technology such as 3D printing to benefit the world. We should not abuse the benefits that this technology can bring to mankind on a larger scale.
