FDM
Frequency Division Multiplexing (FDM) is a process where multiple materials or colors are used to create a single 3D printed object. FDM works by using a single extruder with multiple nozzles or a multi-extruder setup, where each extruder is loaded with a different material or color. The printer's software controls the extruder's movements and temperature to melt and deposit the materials layer by layer. The software also determines when to switch between extruders to create the desired design. FDM with multiple materials can be used to create complex and functional objects with varying properties, such as flexible and rigid parts within the same object. It can also be used to print objects with different colors or textures. FDM with multiple extruders can increase printing efficiency by allowing multiple parts to be printed simultaneously. However, it can also increase the complexity of the printing process, requiring more calibration and maintenance to ensure each extruder is functioning correctly. Overall, FDM with multiple materials or colors is a useful technique in 3D printing, allowing for greater design possibilities and customization.
