choosing the right hotend

 

Every machine has a characteristic tool and in the case of 3D printers is the hotend. It is responsible for melting the filament to be deposited in layers during the printing process.

Choosing a hotend is choosing between the time it will take to print, the surface quality, and the resistance of the piece.

With several models available it can be a complex task, but we have created this article with quality comparisons, time, and resistance to facilitate the task.

Time and resistance

The amount of material that is extruded depends on the diameter of the hotend,  the more quantity that can be extruded the less time the printing process will take. Also, the thickness of the layers determines how strong the part is.

The following graph shows how the resistance of the piece increases and the printing time is reduced as the diameter of the hotend increases.

Superficial quality

The layer height and the hotend thickness define the surface quality of the printed model. The surface becomes smoother when using thinner hotends and smaller layer heights.

The following images show how surface quality varies with different hotends and layer heights.
