Abstract

One of the main processes within the additive manufacturing is fused deposition modeling, due to its versatility, its high capacities, and its low cost. However, this process has certain restrictions that enhance its expansion in the industrial sector such as porosity in the structure and reduced surface quality, in addition to the anisotropy generated by the trajectories and deposition of the layers. Also the current trend in the world is to reduce the consumption of petroleum-based polymers, so alternatives must be found in biodegradable materials to move the process toward an ecosustainable industry. Therefore, this chapter compiles an introduction to the state of the art of this technology of such potential with the use of a biodegradable polymer, polylactic acid. It considers the characteristic defectology of this process, the main parameters, as well as the possible applications in which it is implanted and in which it could be implanted. Finally, different possibilities are considered for improving the surface quality of the parts generated with this technology by means of different types of post-processing
