How to Make a 3D Printer Extruder?

how to make a 3d printer extruder

In this guide, we will be covering the basics of how to make a 3D printer extruder. We’ll go over the different parts you’ll need and how to put them together. With a 3D printer extruder, you’ll be able to create complex shapes and objects with ease.

What is a 3D Printer Extruder?

A 3D printer extruder is a device that is used to push molten plastic through a nozzle to create three-dimensional objects.

Extruders come in various sizes and shapes, but all of them have the same basic components. These include a heating element, a motor, and a nozzle.

The heating element is used to melt the plastic so that it can be pushed through the nozzle. The motor is used to give the plastic the force it needs to go through the nozzle.

The size of the nozzle determines the diameter of filament that can be used with the extruder. Nozzles come in various sizes, but most 3D printers use a 0.4 mm nozzle.

A 3D printer’s extruder is a vital part. It is responsible for creating the objects that you print.

3D printers use two different types of plastic: ABS and PLA. ABS plastic is more durable and stronger than PLA. However, it is also more difficult to work with because it requires higher temperatures to melt. PLA plastic is easier to work with, but it is not as strong or durable as ABS plastic.

Most 3D printers use PLA plastic because it is easier to work with.

The Different Types of Extruders

Before knowing how to make a 3d printer extruder let us discuss the different types of extruders. Several different types of extruders can be used with 3D printers. The most common type is the filament extruder, which uses a spool of plastic filament to create objects. Another type is the powder extruder, which uses a bed of powder to create objects.

Extruders can also be classified based on the way they operate. The most common type is the direct drive extruder, which uses a motor to directly drive the filament through the nozzle. Another type is the Bowden extruder, which uses a separate motor to drive the filament through a long tube to the nozzle.

The type of extruder you use will depend on your specific needs. If you need to print large objects, you will need a larger extruder. If you need to print with multiple materials, you will need an extruder that can handle multiple filaments. You should also consider the speed and accuracy of the extruder when making your decision.

The Pros and Cons of an Extruder

An extruder is a device that is used to push material through a die or mold. It is often used in manufacturing processes such as injection molding and extrusion.

There are both pros and cons to using an extruder. One of the main pros is that it can be used to create very precise shapes. The material can be pushed through the die with great accuracy, which means that the final product will be very close to the desired shape. Additionally, an extruder can be used to create products with very smooth surfaces.

However, there are also some cons to using an extruder. One of the main disadvantages is that the process can be very slow. In some cases, it can take hours or even days to push the material through the die. Additionally, the process can be very expensive. Extruders can be expensive to buy and keep up with, and they usually need a lot of power to run. Now let us know how to make a 3d printer extruder.

How to make a 3d printer extruder

There are a few different ways that you can make an extruder for your 3D printer. One popular method is to use a syringe filled with melted plastic. This syringe is attached to a stepper motor, which is controlled by the 3D printer’s electronics. Through a small nozzle, the melted plastic is pushed out to make the 3D print.

Another popular method for making an extruder is to use a filament feeder. This feeder is made up of a spool of plastic filament that is fed through a heated nozzle. The filament is melted as it passes through the nozzle, and this molten plastic is used to create the 3D print.

Whichever method you choose, it’s important to make sure that the extruder is well calibrated. This will ensure that the 3D prints are of good quality and have smooth surfaces.

3D Printer Extruder Recipes

The extruders in 3D printers are what melt the filament and put it on the build platform. They come in a variety of sizes and shapes, but they all perform the same basic function.

The most important part of the extruder is the hot end. This is where the filament is melted and then pushed through a small nozzle. The diameter of the filament that is put on the build platform is based on the size of the nozzle.

Extruders also have a cold end. This is where the filament is cooled before it enters the hot end. This helps to prevent jams and clogs in the extruder.

There are two main types of 3D printer extruders: direct drive and Bowden. Direct drive extruders are mounted directly on the hot end. This gives them better control over the filament, but they are also larger and heavier.

Bowden extruders are mounted on the side or back of the printer. They use a tube to guide the filament to the hot end. This makes them lighter and easier to move, but they can be less precise than direct-drive extruders.

When choosing a 3D printer extruder, you need to consider the type of filament you will be using. Here is how to make a 3d printer extruder.


Making your 3D printer extruder can be a fun and rewarding experience. With the right materials and a little bit of know-how, you can create an extruder that is custom-tailored to your 3D printing needs.
