Translated title:
Characterization of smart behavior of 4D printed ABS structures
Summary:
The present thesis focuses on the demonstration of the smart behaviour of four-dimensionally printed thermoplastic structures, specifically from ABS (Acrylonitrile butadiene styrene) material, through a methodical experimental process. In particular, the phenomenon studied is 4D printing, an advanced technology that combines 3D printing with the ability of materials to change shape and properties when exposed to external stimuli such as temperature, humidity, light or other physical conditions. This research focuses on the response of these 3D printed ABS structures to thermal stimuli and investigates how various printing parameters affect their shape change capabilities. To simplify the experimental procedure and to better understand the parameters affecting the phenomenon, the Taguchi experimental design method was used, which allows simultaneous control of several parameters in an efficient manner. Statistical analysis was also performed using ANOVA (Analysis of Variance) to quantify the effect of the parameters that contributed to the shape change. Finally, regression equations were developed, allowing the prediction of the behavior of thermoplastic structures, enabling the optimization of four-dimensional printing and opening new perspectives for its application in different fields.
