Rheology Rheology is the study of the flow and deformation of materials, crucial in 3D printing for understanding filament extrusion, resin viscosity, and powder spreading. It affects layer bonding, dimensional accuracy, and surface finish. Rheological properties like viscosity, shear rate, and elasticity influence print speed, resolution, and mechanical strength. Advanced rheometers measure material behavior under different temperatures and shear conditions. Proper rheology analysis ensures consistent extrusion, optimal layer adhesion, and high-quality prints. It is essential for developing new materials, composites, and multi-material compatibility. |
