Dual Extrusion Dual extrusion is a 3D printing capability that uses two separate extruders or nozzles, enabling the printer to work with two different filaments simultaneously. This feature allows for multi-color printing or the use of dual-material combinations, such as a rigid filament for the model and a soluble filament for supports. Dual extrusion significantly expands design possibilities, especially for creating complex geometries, intricate patterns, or parts with mechanical functions. However, dual extrusion printers require additional calibration to align the two nozzles precisely, and print settings like temperature, retraction, and flow rate must be optimized for each filament type. Despite its complexities, dual extrusion is popular among professional users seeking greater versatility and creative freedom. |
