Buying Debates: Buying the Best 3D Printer Extruder

What to Look for in the Best 3D Printer Extruders

If this is your first time buying an extruder for your 3D printer, it is essential that you know about the most critical parts of this component. These parts should also help with your final purchase decision:

1.    Nozzle

The first thing to consider when looking for the best 3D printer extruder is the nozzle (that most products come equipped with). The nozzle is responsible for allowing filament to flow out over the 3D printable object and for this reason, it could significantly affect how precise your end product is.

Typically, the diameter of a nozzle signifies how fast an object can be 3D printed since a larger nozzle can deposit filament at a faster rate. Do keep in mind that your final decision will have you choose between speed and precision since it is quite impossible to demand both at the same time. However, the E3D Titan Aqua is an exception because it is compatible with both 3mm and 1.75mm nozzles.

2.    Heat Block

Before the filament is deposited through the nozzle, it is heated to become more malleable. This is why the heat block is another very important part of the 3D printer extruder. As you can imagine, issues with the heat block could cause the whole 3D printer to fail.

Heat blocks are forced to stand firm against constant heating and cooling – which is also why they are susceptible to failure. For this reason you should look for high quality heat blocks that are built to last.

3.    Heating Barrel

The heating barrel is that part of the 3D printer extruder where the filament is kept while it is heated. While the heat block is responsible for producing the required amount of heat, the heating barrel is the part of the extruder where heat is transferred. In a nutshell, before you fire up your 3D printer, the filament will be waiting inside the heating barrel.

Since this part of the machine is responsible for the contraction and expansion of the filament, the durability of this part needs to be carefully considered.

4.    Build Quality

Due to the expectation of reliability from a 3D printer extruder, it is important that you look for products that are known for their superior build quality. Oftentimes, the products that are manufactured with higher standards will cost a lot more than others. Of course, not having to replace an extruder from time to time will automatically save you money in the long run.

Conclusion

We sincerely hope that this guide helps you find the best 3D printer extruder for your needs. It can be difficult to find reviews for these niche products, not to mention their individual components.

Once you have read through our buyer’s guide, you will be well equipped to pick out one of the 9 reviewed products in this post. If you’re still confused as to which product is the safest bet, we would highly recommend the Diabase Flexion Retrofit Kit for Single Extruder.

With that said, we would like to thank you for taking the time to read our guide and good luck finding the best component for your 3D printer!

FAQs

What Is a 3D Printer Extruder?

A 3D printer extruder is a series of components that work in synergy to move filament towards a ‘hot end’ which prepares the filament to be deposited for FDM 3D printing.

Can You Convert 3D Printers With 3mm Extruders to a 1.75mm Extruder?

In the past, 3D printers with 3mm nozzles dominated the marketplace. However, nowadays 1.75mm filaments are the new trend and therefore most extruders are built accordingly.

If you have a 3mm extruder, you can easily convert them to 1.75mm with a few simple tools including a 1.75mm hot end and TPFE tube (there are many how-to YouTube tutorials that cover this topic).

What Are the Main Parts of a 3D Printer Extruder?

The main parts of a 3D printer extruder include:

The Cold End:

  • Stepper Motor (typically a NEMA17)
  • Filament Drive Gear (a.k.a ‘the hobbed gear’)
  • Idler (usually a PTFE tube or a bearing)

The Hot End:

  • Heater Cartridge
  • Thermistor
  • Heater Block
  • Heater Break
  • Nozzle
