Nozzle in 3D Printer: All Nozzle Types, Sizes And Cleaning

The nozzle in a 3D printer is the component that deposits the molten filament into the build area to create a 3D print. It is a crucial part of the 3D printing process, responsible for extruding the material onto the build plate layer by layer.

Nozzle in 3D Printer

There are many different types of 3D printer nozzles available, each with different uses and capabilities to cater to the diverse needs of 3D printing. The most regularly used 3D printer size for a nozzle is 0.4mm.

Types of Nozzle Available For Your 3D Printer: 

There are many types of Nozzle in 3D Printer. They mainly differ by the type of material used to create this nozzle. Let’s look at them one by one.

1. Brass Nozzle: A brass nozzle is often used in 3D printing because it heats up well and doesn’t cost much. But, it can get worn out fast if you use it with rough materials.

2. Stainless Steel Nozzles: This type of nozzle is more durable than brass and is often used when printing with abrasive materials that can wear out a brass nozzle. However, it doesn’t conduct heat as well as brass.

 3. Hardened Steel Nozzles: Hardened steel nozzles are made of hardened steel material. They are more durable and resistant to wear than traditional brass nozzles, making them ideal for printing with abrasive filaments such as carbon fiber, metal, or wood-filled filaments. Hardened steel nozzles are also suitable for printing with high-temperature materials that require a higher melting point than brass nozzles can handle.

4. Ruby Nozzle: The Ruby Nozzle is a type of 3D printer nozzle designed by Olsson. It is known for its durability and high-quality prints, especially with abrasive filaments like carbon fiber, which can be challenging to print with standard brass nozzles. The Ruby Nozzle is made of a special material that reduces the risk of clogging and provides better layer adhesion, resulting in smoother and more precise prints.

5. Tungsten Nozzle: Tungsten nozzles are made of tungsten or tungsten carbide. They are known for their durability and are suitable for printing with abrasive or high-temperature filaments. Tungsten nozzles can withstand the wear and tear associated with abrasive filaments like carbon fiber and are used in demanding printing applications where standard nozzles may not be suitable.

Common Nozzle Size Available(In mm):

The default nozzle size on most FDM 3D printers is 0.4 millimeters, which offers a good balance for both print speed and level of detail. However, it is important to note higher the nozzle size lesser will be the detailing. But with a larger nozzle size, you will print fast.

Nozzle in Different Size

1. 0.1mm: This is the smallest size commonly used. It’s great for highly detailed prints, but it’s also the slowest because of its small output.

2. 0.2mm: This is a slightly larger size that still provides a high level of detail. It’s a bit faster than the 0.1mm nozzle.

3. 0.3mm – 0.4mm: These sizes are often considered the standard for FDM 3D printers. They offer a good balance between speed and detail.

4. 0.5mm – 0.6mm: These sizes are faster and can print stronger parts due to the larger layer height, but you will have to sacrifice some detail with it.

5. 0.8mm – 1.0mm: These are the largest common sizes. They print very quickly and can produce strong parts, but the level of detail is significantly lower.

Benefits Nozzle Offers in 3D Printer:

The Nozzle in 3D printing serves a crucial role. It’s the component that heats up and extrudes the filament, essentially drawing your design layer by layer. The size of the nozzle also determines the precision of the print, with smaller nozzles providing finer detail.

Benefits of Nozzle in 3D Printer

1. Material Extrusion: Nozzle is used to extrude molten material onto the print bed, layer by layer, to create the desired 3D object.

2. Layer Adhesion: Nozzles ensure proper layer adhesion, which is essential for achieving strong, durable prints.

3. Print Speed and Detail: Nozzle size and material can affect print speed and the level of detail in a 3D print.

4. Durability: Nozzles need to be durable and resistant to wear, especially when printing with abrasive filaments or high-temperature materials.

5. Directional Control: Nozzles are used to direct the flow of molten filament in a specific direction given in the Gcode file.

6. Compatibility: Nozzles need to be compatible with the specific material being used in the print. For example, brass nozzles are commonly used with standard filaments like PLA, ABS, and PETG, while hardened steel or other specialty nozzles are suitable for abrasive or high-temperature filaments.

7. Cost and Material Efficiency: Smaller nozzles use less material, which can result in cost savings and extended material life.

Nozzle Heating Temperature For Different Filaments Types:

Nozzle heating temperatures in 3D printing differ due to varying material melting points. For example, PLA needs around 180-220°C, ABS requires 220-250°C, while PETG and Nylon have different optimal temperatures. Let’s look at each one by one.

Nozzle Heating Temperature For Different filament


Here are some common 3D Printing Nozzle Printing Temperature for different filaments: 

1. PLA (Polylactic Acid): The recommended temperature is between 180°C (356°F) – 220°C (428°F).

2. ABS (Acrylonitrile Butadiene Styrene): The recommended temperature is between 220°C (428°F) – 250°C (482°F).

3. PETG (Polyethylene Terephthalate Glycol-modified): The recommended temperature is between 220°C (428°F) – 250°C (482°F).

4. Nylon: The recommended temperature is between 240°C (464°F) – 260°C (500°F).

5. TPU (Thermoplastic Polyurethane): The recommended temperature is between 200°C (392°F) – 220°C (428°F).

How to Clean Your Nozzle in 3D Printer: 

Cleaning the nozzle of a 3D printer is an essential maintenance task that helps ensure optimal printing performance and avoid clogging issues. Here are a few things you can consider to clean your nozzle. Most of these items are cheap and easily available at stores or online.

 1. Use a Nozzle Cleaning Needle: You can use a nozzle cleaning needle/wire to remove any remaining debris from the nozzle. Be careful around the thermistor and heater cables, or turn off the power after heating the hot end to the target temperature.

2. Heat Gun and Brass Brush: In this method, you will heat the nozzle with a heat gun and then use a brass brush to clean it. This method is effective but may not be suitable for all types of nozzles.

3. Soaking the Nozzle In Chemical Solution: If your nozzle clog is severe, you might need to remove the nozzle and soak it in a cleaning solution. Acetone works well for ABS, and isopropyl alcohol for PLA. After soaking, you can use a needle or wire to remove any remaining debris.

4. Reassemble the Nozzle: Once your nozzle is clean, you can reassemble it. Make sure to heat the nozzle before you insert the filament to ensure it goes in smoothly.
