Influencia en las tolerancias de productos fabricados por manufactura aditiva

Abstract

This document describes the dimensional analysis of elements developed by 3D printing, taking into account the development properties that these machines can achieve, specifically the project will focus on FDM (Fused Deposition Modeling) printing technology, several prints are made with different configurations properties, analyzing which are the properties that most affect the dimensional specifications, so an experimental statistical technique was used to determine the best combination of product variables. In addition, this project describes the design stages of products made by additive manufacturing, from design to possible quality evaluation. For the impressions made, their possible assemblability was taken into account, so an element with specific geometries was studied and the impressions were developed at a scale according to the printing ranges of the machine used, analyzing the capabilities of the process in aspects of possible tolerances. . that benefit or affect the measurement results obtained, providing a new study on the precision and accuracy of additive manufacturing. The study was supported by a statistical program, in which a simulation can be generated towards the printing results and thus be able to compare the real results obtained with those of the simulation, the support program in minitab 19.
