![]() ![]() The specific temperature requirement depends on what type of filament is used. Print beds typically are kept somewhere between 122 and 212☏ (50 and 100☌). Most print beds are heated to prevent the plastic from cooling too quickly and creating product warp. The print bed is the surface on which filament is deposited in a specified shape during the printing process. This piece senses and helps regulate the temperature of the hot end. This cooling element helps keep heat from entering parts of the extruder that need to stay at lower temperatures.Īnother element of the extruder that is worth mentioning is the thermistor or thermocouple. The heating element melts the filament as it passes through the thermal tube and reaches the nozzle.Īlso within the extruder is a heat-sink fan. Typically, this is made of aluminum and is heated by a heater cartridge. ![]() Within the extruder’s hot end is the heating block. It is composed of a cold end, which pulls filament through the system, and a hot end, which melts the filament as it is extruded. The extruder is where most of the printer’s technology is located. A few key components create and manage heat within an FDM printer:Ī closer look at each will explain how they affect print outcome.Įxtruder. ![]()
