3D Printer Extruders: Best Options
Best 3D Printer Extruder: Image Source: myminifactory.com
Printers, as well as extruders, are equally diverse and can be found in various shapes and sizes. Many extruders are only specific to a particular printer. The best-looking 3D prints can be obtained with the help of high-quality extruders.
The 3D printer extruder is the vital part of the 3D printer, which ejects some liquid or semiliquid material for depositing it in successive layers of 3D printing volume. Hence extruder is the most critical component of the 3D printer. A 3D printer extruder is used for melting and pushing out the filament.
Two types of 3D printer extruders are available for FDM printers: Direct and Bowden extruders. Both of these extruders have their benefits and are handy for different situations.
Let’s learn a bit more about extruders!
What is a 3D Printer Extruder?
The extruder is the part of the FDM 3D printer that melts by pushing out plastic filament to create a 3D object. The extruder has a group component. The first group of features is called the Cold End, and the second is called the Hot End.
Two types of 3D printer extruders are Direct extruders and Bowden extruders. Direct extruder systems can be easily recognized by looking at the 3D printer extruder. The extruder motor is placed on top of the hot end and moves along. This allows a short filament path, resulting in better retraction properties and print quality. Direct extruders are filament compatible. The design of the direct extruder is a bulky hot-end design which results in slower printing.
The direct extruder has a consistent and predictable extrusion rate, reasonable retraction control, and comprehensive material compatibility. It has some negative points, such as it reduces the maximum print height and having low print speed.
In the Bowden extruders, the cold end is mounted onto the 3D printer's frame instead of above the hot end, as in the direct extruder. This setup is lightweight, which increases the speed of printing without having issues like ghosting and ringing.
In this article, we discuss the leading 3D printer extruders.
1. Micro Swiss All Metal

Micro Swiss All Metal Hotend Kit is mostly suitable for high printing temperature material. Micro Swiss lack a PTEE liner which helps it to attain the maximum temperature of 280-300 degree Celsius without producing dangerous gases (from burning of the PTEE tube). However, all-metal hot-end extruders, due to their capacity to handle high temperatures.
Micro Swiss All Metal also has a metal throat (made of Grade 5 titanium alloy) which connects the heatsink and heat block. Titanium not only has great heat isolation properties but also is a highly durable material. Titanium material offers three times lower conductivity than stainless steel, which is typically used for hot-end throats.
2. E3D Hemera

E3D Hemera is one of the most potent extruders available on the market today. It has a dual driver gear system which helps give out almost 100 N of pushing force on the filament. This helps in providing high extrusion rates without stripping the filaments.
Due to the high pushing force of the E3D Hemera, it is a great extruder choice for a large 3D printer that requires high flow rates. It has T- slot mounting, which allows this extruder to be mounted virtually on any 3D printer. It can be available in both the direct and Bowden extruder setups. If you are looking for a high-performance and reliable extruder, then E3D is an excellent choice. It offers an optimized airflow circulation.
3. BIQU H2

BIQU H2 is a type of direct extruder that uses 1.75 mm diameter filaments, weighing 211 gm and a gear ratio of 7:1. BIQU H2 can apply up to 7.5 kg of extrusion force which depends on the type of filament material used. This enables better print accuracy. The price of the BIQU H2 extruder is $70 - $100. BIQU H2 extruder sits right above the print head, making the overall print head system heavier than some other extruders. This makes the print speed slower than usual.
4. Bondtech BMG

BIQU H2 is a type of extruder with 1.75 mm diameter filaments, having a gear ratio of 3:1. This gear ratio enables the Bondtech extruder to feed the filaments faster and print the parts swifter compared to the previous BIQU H2 extruder. This is the lightest extruder weighing only 75gm. It is available in both types of extruder, direct and Bowden. It costs $80 - $100. This extruder has a dual drive which allows for uninterrupted filament feeding. Its lightweight will enable you to print parts fast with greater accuracy.
5. E3D Titan

E3D Titan extruder has a gear ratio of 3:1. This extruder uses the transmission ratio, which helps reduce the rotational speed of the gears that feed the filaments. This allows not only the powerful flow of the print material but also steady flow as opposed to direct drive extruders like Micro Swiss, which allows for faster material flow but cannot handle the flow's consistency. E3D Titan can be used with diameter filaments of 1.75mm or 2.85mm. Titan costs $35 – 54, which makes it one of the budget-friendly and most productive extruders on the market today.
6. Slice Engineering Mosquito

Slice Engineering Mosquito is a new to the market and is quite successful. It has a unique setup, and due to this, it offers several benefits in its thermal performance. Copper can replace an aluminum heat sink as this sink does not have to suffer a mechanical load, and heat creep is effectively eliminated. Mosquito is an extruder that uses 1.75 mm diameter filaments and fits on the FDM printer.
Here heater block is directly connected to the frame with the help of four stiff rods. Slice engineering mosquito is compatible with E3D’s entire range of products. If you are looking for top performance and can pay accordingly, then this Mosquito will be the right choice.
Things Need To Consider Before Selecting the Best 3D Printer Extruder
Here we mention some criteria to follow while choosing the 3D printer extruder.
- Determine which factor, print speed or accuracy is more significant for your project.
- Each extruder is compatible with the particular type of material used for your print parts and specific sizes of the filaments. So choose the one according to which material you are required to print parts.
- According to the size of the parts, choose the extruder. Bowden extruder is suitable for the smaller details.
- Consider your budget for a 3D printer extruder. Bowden extruders are less costly than direct extruders.
- Consider the easy-to-use and compatible extruder for your 3D printer.
- The durability of the extruder is also the most important factor. So choose the durable 3D printer extruder which is having warranty period.
