A 3D printer head, also known as a print head or extruder, is an essential component of a 3D printer. It is responsible for depositing the material in precise layers to create a three-dimensional object. The print head moves along the X, Y, and Z axes, following instructions from the 3D printer's control system.
Here are the key elements of a typical 3D printer head:
Nozzle: The nozzle is the small opening through which the material, typically molten plastic filament, is extruded. It determines the diameter of the filament and plays a crucial role in determining the level of detail and accuracy of the printed object.
Heater: The heater is a heating element located near the nozzle. It raises the temperature of the plastic filament to its melting point, allowing it to be extruded through the nozzle.
Thermistor: A thermistor is a temperature sensor used to monitor and regulate the temperature of the print head. It provides feedback to the 3D printer's control system, ensuring the proper melting and flow of the filament.
Cooling fan: To prevent the printed object from warping or deforming, especially in the case of materials like PLA, a cooling fan is often attached near the print head. It provides a controlled flow of cool air to rapidly cool down the filament after it is deposited.
