Evaluation on material supply characteristics of material extrusion in high gravity

Abstract

In recent space projects, 3D printers have been gathering attentions because of their excellent resource- and space-saving characteristics, and still have several technical problems such as the instability in material supply in zero gravity. This research conducts the 3D printing process in high gravity to transform the technical problems in zero gravity into enormous merits. By evaluating the influence of the nozzle temperature, the outlet diameter of nozzle, and gravitational acceleration on the material supply in material extrusion, this study aims to enhance the fabrication resolution drastically in high gravity.
