Nozzle Expansion Nozzle expansion is a phenomenon where the extruded filament diameter increases slightly due to pressure and temperature variations. This affects print accuracy, layer adhesion, and surface finish. Compensation techniques involve adjusting extrusion width, flow rate, and print speed. Advanced slicing software accounts for nozzle expansion by modifying toolpath calculations. Understanding nozzle expansion is crucial for precise dimensional control, especially in functional and mechanical parts. Material properties like viscosity and thermal expansion also influence nozzle expansion behavior. |
