Your Next 3D Printer Extruder Buying Guide

Following are some of the factors you need to consider when choosing you next extruder.

Types

There are two types of 3D printer extruders, including direct extruders and Bowden extruders. Choosing between these two options will depend on your needs.

Direct 3D Printer Direct Extruder

It is known as direct as they are attached to the hot end directly. These are most commonly integrated into plug-and-play 3D printers. Moreover, they come with gears. Science direct extruders are incorporated with hot ends; it reduces the distance that the filament needs to travel. There are fewer variables that can go south and less time and distance for the filament to deal with issues. This is considered to be particularly valuable in 3D printing flexible filaments.

3D Printer Bowden Extruder

They are directly connected to the hot end. Instead, the Bowden extruder comes with a PTFE tube that links the extruder with the hot end. This form of tube is also known as the Bowden tube.

Heat Block

The heater block is an integral part of the extruder as it helps in heating the filament. This part generates the heat to melt the filament and often deals with reliability issues. The regular heating and cooling of the heater block makes it vulnerable to failure

Nozzle

3D printer extruder comes with nozzles and is among the most important factors to consider. The nozzle integrated into the extruder allows the filament to flow out onto the object. Therefore it will have a considerable impact on the precision of the end results. Moreover, the diameter of the nozzle will decide how fast the object is designed as it will deposit more filament altogether. Oftentimes you have to select between speed and precision when considering the diameter of the nozzle. Unfortunately, you cannot get both together.

Build Quality

A lot relies on the 3D extruder; therefore, you should look for models featuring superior quality built. Products that are manufactured to comply with higher standards are likely to cost more. However, you can rest assured of their reliability and durability.

Heating Barrel

It is the area where the filament gets collected when it is heated. Although the cartridge is responsible for generating the heat, the heating barrel is the part where the heat comes in the end. So the heating barrel you choose must be able to deal with the expansion and contraction of the filaments. Considering that it is heated and cooled frequently, durability should be your consideration factor.

Frequently Asked Questions

Q: Are dual extruders worth it?

People, especially ones who are merely starting out their journey with a 3D extruder, go for single extruders. This is because investing in dual extruders  adds a level of complexity to the printing endeavors. On the other hand, there are many benefits of dual extruders. It allows you to design more engaging and gravity-defying models through support filaments. Moreover, dual extruders also make it easier to develop multi-colored prints.

Q: What does the hot end do in a 3D printer?

The hot end is an important element of a 3D printer, which melts the filament for extruders  and assists in maintaining an accurate and consistent temperature to obtain successful prints.

Q: Do 3D printers require heat to function?

A 3D printer needs a heated bed if you want to get 3D printed with ABS material. The contraction rate of ABS is rather high, which results in warping issues during the printing process. If the bed can be heated, ABS will be incorporated on the heat bed firmly and reduced chances of warping.

Q: What is the most flexible 3D printing material?

There are different materials that come with flexible properties; the two major kinds of flexible filaments include Thermoplastic Elastomer and Thermoplastic Polyurethane. These filaments are designed using thermoplastic elastomers that are acquired from a combination of soft rubber and hard plastic. Among both, thermoplastic polyurethane is the commonly used flexible material in the industry.

Q: Does room temperature affect 3D printing?

You can 3D print in a hot or cold room as long as your 3D printer holds proper conditions like the right materials, consistent printing temperature. Moreover, if you 3D print ABS in a cold room, you are probably dealing with a lot of warping issues. But you can pull off PLA in a cold room.

Q: Is PLA or ABS stronger?

To begin with, they are both thermoplastics. When it comes to choosing the stronger among them, PLA is stiffer and stronger than ABS. However, it lacks heat-resistance abilities, so they are more suitable for hobbyists. Although ABS is less rigid and weaker, it is lighter and tougher, making it ideal for prototyping applications.

Conclusion

Buying the best 3D printer extruder does not have to be that difficult if you know where to look for it. Here we have carefully selected and reviewed some of the best extruders out there so that you spend less time picking and evaluating the products. Eventually, the kind of extruder you choose should be able to cater to your printing needs.
