Comportamiento al creep de un polímero utilizado para impresión 3D

Abstract: RESUMEN En los últimos años se está utilizando, ampliamente, la construcción aditiva o impresión 3D, para la fabricación de bienes tecnológicos. Este procedimiento de construcción tiene y tendrá un gran impacto industrial. Existen muchos procedimientos de impresión 3D y entre ellos el más conocido se denomina Modelado por Deposición de Filamento (MDF). El objetivo del presente trabajo se orienta a la caracterización experimental de propiedades mecánicas de piezas construidas por impresión 3D con polímeros plás… Show more

“…Some researchers have experimentally investigated the effects of environment variables on creep. Temperature-humidity [19] and creep load [20] are considered variable parameters when these studies are examined. Various models have been used to predict creep in some studies.…”

“…According to Molina, Pender, Moro & Piovan (2018), when setting the temperature conditions when it is printing, it is possible to obtain the maximum creep resistance. By means of thermofluence tests they conclude that when stresses greater than 20 MPa are applied, significant decreases are evidenced of mechanical resistance; however, the atmospheric conditions must be considered, so that the mechanical properties obtained are met.…”

“…Source: (Taken from: Molina et al, 2018) It is obtained by fermentation of a vegetable raw material with certain strains of bacteria. It presents a wide range of properties since there are different grades, with different molecular weights, stereochemistry, and morphology, ranging from the amorphous state to the semi-crystalline state.…”
