An extruder is one of the most crucial components of a 3D printer. It is responsible for drawing in, melting, and pushing out the filament. The extruder is sometimes referred to as a fancy hot glue gun. In other cases, it helps solidify the powder form by depositing a bonding agent. It might be small, but it serves an essential purpose.
That is why Snapmaker made the snapmaker 2.0 dual extruder to ensure your creation is as perfect as possible with no faults. Before we go on, you first need to understand the basics of an extruder.
What is an extruder?
It is the part of a 3D printer where the material is ejected in liquid or semi-liquid form. The material is deposited in successive layers. In some cases, as said earlier, the extruder only serves to deposit a bonding agent. The bonding agent solidifies the material, which is originally in powder form.
Main elements of an extruder
There are two main elements in the extruder. These are the cold and hot ends. The cold end is the upper portion of the 3D printer extruder system, where the filament is fed. The hot end is where the filament gets melted and squirted out.
· Cold end
It consists of a stepper motor, toothed gears, hobbed bolt or gear, and a spring-loaded idler to hold the filament. For most desktop 3D printers, the stepper in the cold end drives the motion and extrusion of the filament. The DC motor is brushless and is aimed at achieving a high level of precision. Full torque is imparted at low speeds.
· Hot end
This is where the filament is passed for melting and extrusion onto the print end. When the filament passes through the hot end, it transitions from solid to liquid. So, during the printing process, the filament travels from the cold end to the hot end. It then passes through the nozzle, where it liquefies.
