Extruder and Hotend for 3D Printers: Briefly about features and selection tips
Every component for a 3D printer is critically important for any 3D printing enthusiast. After all, every part affects the quality of printed models, productivity, and the service life of your equipment. In this article, we will look at some of the most important components of 3D printers, how they work, and where you can buy them.
3D printer extruder — a mechanism that pushes plastic filament and feeds it for further heating. The constant components here are coldend and hotend:
Coldend
Responsible for moving the filament. The motor and gearbox work to guide the plastic through a PTFE tube, or directly into the hot part. There are different types of cold ends that have a slightly different principle of operation, and we will look at them a bit later.
Hotend
Heats and melts the filament layer by layer through a nozzle. The two main components here are: a heater that heats and melts the thread, and a special nozzle that directs the plastic during its extrusion.
It can be concluded that these elements are inseparable, as a hotend for a 3D printer simply cannot function without a feeding mechanism. You can buy an extruder for a 3D printer in our Look-Feel-Live-3D online store, but before that, we will tell you what types of extruders there are so that you know exactly what to choose.
Direct
The monofilament is fed to the heating part in one piece, meaning the drive and gear that move the material along are located directly near the hot end. Thus, extrusion can happen very quickly because the feed distance is small, so the probability of problems during extrusion is lower.
Bowden
Here the hot and cold ends are separated by a PTFE tube through which the plastic monofilament passes. The Bowden extruder is slower due to the longer path of the rod, but with its help, you can print high-quality models. Note: the Bowden extruder is not suitable for making models from TPU and elastomers.
Dual
Found on the equipment of some 3D printers. The main feature is the ability to print with several materials simultaneously or sequentially. Dual extrusion allows you to speed up the work process since there are two tools for moving, melting, and pushing.
We hope that this information was useful for you and will help you make the right choice. And you can also order a hotend for a 3D printer on our LFL3D website. We offer a wide range of spare parts and consumables for 3D printing from leading manufacturers.
