Expressive Fused Deposition Modeling by Controlling Extruder Height and Extrusion Amount

Abstract

Fused deposition modeling (FDM) 3D printers form objects by stacking layers having a linear structure. To print fine structures, an appropriate choice of parameters is necessary, or printing error occurs. On the other hand, the printing error is exploited as an expression technique. However, the relation between the printed structure and the parameters causing the printing error is unclear. In this paper, we focus on the height position of the extruder and the amount of extruded material, and explore the combination of these parameters to enhance the capability of FDM. By extending an equation that calculates the amount of material from the layer height, we investigate the behavior and structure of material extruded from various height positions. On the basis of experimental results, the printed structure is classified into six categories according to the structural feature. We describe these structural features and demonstrate examples with new inherent expressions for FDM.
