Enjoying 3D printing<\/a> does not require detailed knowledge of the construction of 3D printers from their users. However, it is worth learning at least the basics and lighten up a bit on all those mysterious elements that are in these machines. Today, the extruder<\/a>, the little heart of a 3D printer. Let’s take a look at what it is responsible for and what it is used for.<\/p>\n

How is 3D printing done?<\/h2>\n

For most makers and hobbyists, 3D printing<\/a> comes to mind in one way: they see stationary machines, usually not that big at all, that use a process of incremental manufacturing technology known as Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) – depending on who you ask, because the two acronyms mean practically the same thing.<\/p>\n

In a nutshell, the FDM method involves inserting a thread of a plastic material (filament<\/a>) into a hot block of metal with a nozzle. The filament then melts and the motions of the printer position it into the desired contour<\/b>. This path is repeated and stacked progressively until a full 3D object is created. But this is something all Botland blog readers and 3D printer owners know.<\/p>\n

How does the extruder in a 3D printer work?<\/h2>\n

The processing of the material – melting it and “spitting” it out to create the desired model<\/b> – takes place in a group of parts that for some are known collectively as the extruder. Without it, making prints would not be possible. And while mechanically it’s not that complicated, it’s worth knowing that the 3D printer has other parts that make it possible to extrude the filament.<\/p>\n

\"Extruder\"

To begin with – there are two schools of thought. According to some, an extruder is just the motor and associated parts that push and pull the filament. Others consider an extruder to be the entire assembly of components, including the hot end where the 3D printing filament is melted down and settled.<\/p>\n

Let’s look at the extruder comprehensively – as a kit, or set of specialised 3D printer components<\/b>. Explaining how an extruder works requires a close look at two key parts commonly referred to as the hot end (encountered notations: hotend, hot-end) and the cold end. These are the hot end and the cold end.<\/p>\n

Chill-out and print. Extruder and a cold end<\/h2>\n

The cold end refers to the top part of the 3D printer extruder system where the filament is fed and passed to the hot end (the bottom part of the extruder system) to melt and extrude the filament so that it can go to the print bed – this is the basis for our design, the 3D printer work area.<\/p>\n

This component of the 3D printer extruder usually consists of:<\/p>\n
