Abstract

Additive manufacturing has revolutionized the industry given the wide spectrum of fields in which it is applicable, standing out for the possibility of obtaining parts with complex geometries, allowing to work with a wide number of materials and guaranteeing reasonable repeatability and dimensional accuracy. However, as technologies, there are still many aspects to be optimized, which has caused a constant search for improvement, for example, in manufacturing times and in the surface quality of the final products, which are highly dependent on the combination of parameters chosen. Disadvantages such as these said before currently prevent their complete incorporation in industrial manufacturing.
This work addresses the impact of this combination of parameters on printed parts. For this purpose, a mechanical characterization of three materials is carried out by means of tensile and flexural tests: Nylon, Polylactic acid (PLA) and Acronitrile butadiene styrene (ABS), all subjected to different printing conditions. The combination of parameters has been defined from a full factorial design of experiments, thus allowing statistical validation of the results.
The findings of this research make it possible to demonstrate the effect of the variables under study on the mechanical behavior of each of the materials, making it possible to perform statistical correlations and to obtain the optimum combination for each case. This has made it possible to make useful recommendations for possible use in the industry.
