Caracterización del proceso de manufactura aditiva por extrusión

Abstract

Due to the nature of additive manufacturing of layer by layer, parts printed by polymer extrusion present an anisotropic behavior that affects the mechanic properties, resulting in components with less utility when are compared with other manufacturing techniques. According to literature, the air gap, layer height, contour width, bed width, print orientation and raster direction inside others, are part of parameters identified as critical in order to optimize these properties. Not complying with output parameters due to its remarkable variability, provoke also, an increment in costs and print time. Despite of many studies to analyze this topic, the new extrusion printers continue presenting deficiencies and the manufacturers do not provide enough information to diminish the problems in prints. Especially in the manipulation of position parameters of the component in the printing chamber. This project pretends to carry out experimentation to find with more detail, valuable information to classify materials by the process and characterize this according to the initial setting of the machines.
