Present on “more complete” printers and optional on “basic” kit, the fanduct for cooling the freshly extruded filament is a fundamental component to obtain excellent prints.
Ventilation is very important to instantly cool the filament and thus prevent it from deforming while it cools itself. The lack of cooling can lead to overheating problems already discussed in this article.
If this kind of ventilation is not included in our printer, we can add it very easily by joining a fan to a body printed with the same printer.
Looking inside the sites that collect files for 3D printing, the warehouses of 3D models we can certainly find the .stl file designed for our printer.
Once you get the object and coupled with the right size fan and voltage the game is done.
We will also have the ventilation of the plate.
To proceed to fanduct addition we will have to pay attention only to a few steps:
- Print a “fanduct” that is not too invasive or we risk losing sight of the nozzle and its movements.
- Obtain a fan of the right size and voltage
- Probably we will have the possibility to connect this fan to the motherboard of the printer, in this way we will be able to command it from software to decide when to make it work and at what speed.
Note: Using ventilation on some filaments (ABS type) can be detrimental. Incorrect or too extreme ventilation on some types of filaments can lead to delamination phenomena described in this article.
The fan is easily available in the most popular e-commerce, Amazon
