The introduction of dual extrusion FDM 3D printers to the market has opened up countless possibilities. We take a look at what exactly dual extrusion is and some of the ways it’s achieved. What Is Dual Extrusion? Dual extruders of an Ultimaker 3. Source: Ultimaker In the early days of fused deposition modeling (FDM), 3D printers had only a single extruder. That meant that the user could only print in one material at the time. In the last few years, dual extrusion has emerged. With a second nozzle and extruder, makers now have the possibility to print parts composed of two different materials. The process of printing with dual extruders is the same as it is with “normal” FDM 3D printers. The only difference is that the printer automatically switches between filaments at designated times. In the following, we’ll see why this version of the technology has so much […]
