Light, by separating the extruder part from the hotend we have a lighter kinematics assembly that allows us greater acceleration and printing speed Greater weight in the assembly that can cause problems in the kinematics if the chassis/kinematics assembly is not properly adjusted. Reduced distance to the hotend, allows greater control in the flow of the filament in addition to being able to use motors that are more contained in size and weight.

Bowden extrusion, differs from the previous one in that the extruder is not directly attached to the hotend and the filament moves between both parts using a PTFE tube.

Direct extrusion, as its name indicates, the extrusion system is directly connected to the hotend.

Normally we can divide the types of 3D print heads into two types: The thermistor allows the control of the temperature in the cartridge that is distributed by the fuser to the nozzle that acts as the output of the filament at the melting temperature, depositing it to build, layer by layer, our printed pieces.

fuser, thermistor, heating cartridge and nozzle is the so-called hot zone that is connected through the barrel to the rest of the assembly.

sink and barrel, usually the “cold” area of the hotend that prevents the heat generated in lower areas from causing blockages in the flow of filament.

The hotend is usually made up of different parts… Hotend, is the part that is responsible for “melting” the filament to deposit it in our printing area, forming layers that will generate our printed figures.traction gears, they are in charge to push the filament to the hotend.motor, it allows to move the gears that push the filament.Extruder, is the set of parts/components that allow the processing/movement of the filament.We are going to divide the print head into two parts, depending on the type of print head these parts can be more or less integrated or separated:

We have to say that we are not going to review in depth between them since either we have already done it before or we are preparing a more detailed review of them, the objective of this article is to review the most popular ones to help you identify which would be the most suitable for your machines.Īs always, before continuing with the article, remind you that you can join 3DWork in our Telegram channel full of people upset by 3D printing, or on our social networks Facebook, Twitter, Instagram. At the end of the article you will find more information about them.

This set is made up of various components that will allow the processing/movement of the filament, and today we will focus on the best extruders on the market.īefore we begin we would like to thank the collaboration of our colleagues at 3Dboom (Telegram group here ) and 3D-Informatik (contact here) which have provided us with some of the extruders included in this article. Our 3D printers have an assembly inside the print head called an extruder.
