Detailing the configuration to perform better clay printing

In this paper, we introduce an in-depth study on the performance of clay Additive Manufacturing (AM) process under various printing configurations. Our objective is to examine the filament behavior through clay extrusion with the focus on its printability, geometrical accuracy, and mechanical performance. Such research contributes to AM clay and ceramic artefacts in terms of the shaping and durability. The tests initiate with single layer extrusion which intends to investigate the relations between filament profile and input parameters, such as: Extrusion configurations (Layer height H, nozzle diameter D, velocity ratio R between extrusion and nozzle movement) and Printing-path parameters (Curvature). Subsequently, we apply the configurations from single layer extrusion on multiple layers printing test. The benchmark is based on the consistency of filament in each layer, the bonding strength between layers and the maximum flexural stress along build-up direction.
