Abstract

Additive manufacturing is a technology that is currently expanding rapidly due, among other factors, to the flexibility of possible geometric design and the possibility of production without the need for high valued tools and equipment. Among the several different processes of additive manufacturing, the FDM process stands out the most thanks to its simplicity of operation and lower machine costs. Despite the benefits, the FDM process still has problems such as print defects, part deformations that often become unsuitable for use, resulting in wasted time and material. The objective of this work is to define and implement a method for detecting and identifying printing errors. Thus, the manufacturing failures produced in the specimens will be related to the characteristics of the electrical signals captured during the printing process, so that each failure studied is represented by one or more characteristics of the signal.
