Future applications for additive manufacturing have a lot of promise and are growing due to the gradual elimination of technological and financial restrictions. A method used in additive manufacturing (AM) called direct metal laser sintering (DMLS) involves melting and fusing layers of metallic powder to produce 3D objects. Life cycle analysis (LCA) is a technique used to assess a product's environmental effect throughout its life cycle, including the extraction and processing of raw materials, manufacture, distribution, usage, recycling, and final disposal. The goal of this study is to compare the manufacture of metallic scaffolds using additive technology, and DMLS to more traditional methods (metal injection molding process), and to evaluate the environmental, economic advantages (energy and raw materials used), and useful service life of scaffold over the course of the whole life cycle. Generally, the metal injection molding (MIM) process has been used to produce biocompatible titanium scaffolds; however, this technique does not entirely control shrinkage, density, and scaffold porosity. Furthermore, some of the drawbacks of the MIM process include requiring high capital investment and processing costs, suitable for small to medium-sized parts and complicated for some metal products. Thus, there is a need for alternative techniques that are defect-free, provide longer service life, and economically and environmentally viable biocompatible scaffold production.
