3D Printer Nozzle Size And Types: Detailed Guideline For Each Type

In the past decade, 3D printing has opened up many new opportunities in multiple industries. Be it automotive, education, jewelry or healthcare – this technology has brought in so many revolutionary changes in these sectors. Without the right nozzle, none would be possible.

If the nozzle size and type are not correct, your product may not be able to highlight the desired features that your client requested.

This is why every 3D printer enthusiast must be aware of the different sizes and types of 3D printer nozzles. These details will help you make an informed decision.

3D Printer Nozzle Sizes

1. Small


The smallest 3D printer nozzles have an input diameter between 0.1 and 0.25 mm. There are four sizes that you will typically find: 0.1, 0.15 and 0.2.

It is a smart decision to buy the nozzle whose size matches the smallest detail in your 3D projects. It may be ineffective and wasteful to buy a nozzle that is not the right size.


Finest Details

These nozzle sizes are available for 3D printing projects that require the highest precision. These nozzle sizes will allow you to add the finest details to your product to make it stand out from the rest.

These sizes will allow you to create realistic miniatures of different items, people, and characters. This allows you to create impressive action figures of famous characters from movies, TV shows, and comics.

It is possible to create tiny editions of famous automobiles, which highlight their unique features in a humble fashion. You can recreate their steering wheels, speedometers, and seat belts while keeping their real-life attributes.

Supports that can be easily removed

3D printing is unique due to the support structures. Your product will be able to defy gravity for a time and reach the final stage of creation with the support of these structures.

This makes it easier to remove these structures after the process is complete. Because of the increased precision, the amount of filament used here will be less than usual. You may find it easier just to break them off once they have finished their job.

Clogging: Prone

One of the downsides to using tiny nozzles, is their greater proneness to clogging. Their input area is very compact so even a tiny particle can clog the hot end and stop the process.

You can avoid these situations by investing in high-quality filaments that can easily pass through small nozzles.

Overhangs and the difficulties they present

When using a small nozzle, it can be difficult to print overhangs. The overhangs are very narrow in width, so the next layer struggles to keep up. This is why the overhang parts are so fragile that it can be very difficult to create them and take them down.

2. Medium


The most commonly used 3D printing nozzle size is the medium range. Their inner diameters are usually between 0.3 mm and 0.4mm in terms of measurements.

These sizes are 0.3, 0.35, and 0.4 mm. The standard size for 3D printer projects is the last one.


Good Speed and Precision

This range of nozzle sizes is very popular in 3D printing because it offers both precision and speed. You don’t have to lose much on either side while working with them. It can help you with your project’s details without taking up too much of your time.

You can quickly provide the details you need to your customers. Because of this speed, you can take more orders and have them delivered on time.

Works For Most Projects

The standard nozzle, 0.4mm, is fine for most 3D printer projects. It is possible to get a lot done with one size.

This is the closest thing you can find to a universal solution for these nozzle sizes. Although there is no universal solution, this may be the best way to start 3D printing.

0.1-0.3mm Layer Heights

These nozzle sizes can be used to build 3D objects with a layer height of between 0.1mm and 0.3mm. This gives you plenty to experiment with your creativity and skills. For better detail, choose thinner layers. On On the other hand thicker layers can make the job go much faster.

3. Large


The largest nozzle sizes have the most versatility. The nozzles that are large enough for 3D printing typically have a diameter of 0.5 to 1.2mm. They are available in sizes 0.5, 0, 0.6, 0.8, 0.8, 1.0 and 1.2. You can choose the one that best suits your project needs.

High Strength

These nozzles can extrude thicker filaments, which makes the object stronger than usual. If you are currently producing something heavy, durable, and sturdy, larger nozzles might be a good choice.

High Speed

The best thing about these nozzles is the speed at which it completes the job. 3D printing is faster when you can get more filament out in a shorter amount of time. You can switch to larger nozzles if productivity or quantity is important in your business.

3D Printer Nozzle Types Based On Material

1. Brass

Manufacturers most commonly use this material to build nozzles. brass. This metal allows you to explore a wide variety of filaments, except the abrasive. It is compatible with popular filament choices like PETG, PLA, ABSTPE, Nylon

Nearly every FDM printer comes with a brass-nozzle. This is due to its simplicity and affordability. The product will also have excellent stability and thermal conductivity.

2. Stainless Steel

Stainless steel has been known to be a strong material. one of the most durable materials Many industries. 3D printing is less reliable than some other options.

Although it can be used with abrasive materials for occasional use, using them for extended periods of time will reduce its lifespan. This means that you might need to replace the stainless-steel nozzle more often than other more durable options.

A stainless steel nozzle can be used to 3D print products using filaments such as NylonX, carbon fiber and glow-in-the dark. It can be used with filaments with steel, iron, or brass. You can also choose to fill them with ceramic or wood for more exotic filaments.

3. Hardened Steel

Another popular material for 3D printing is hardened steel. This material’s outstanding durability and compatibility are its most appealing features. This material can be used with both non-abrasive and abrasive filaments, unlike the other options.

Hardened steel is a good choice if your projects involve abrasive filaments. It is resistant to wear and tear, even after being used with these materials often. It is actually 10 times more resistant to this type of erosion. They are durable and last a long period of time.

The nozzle’s high temperature can pose a problem. It can be used for any filament, including carbon fiber, glass fibre, and those filled with steel, iron, or brass.

4. Specialty

Some nozzle materials are available for those who prefer to go one better or use more exotic 3D printing options. You can find rare nozzles made from tungsten, ruby and other unique materials by doing some research.

The tungsten and ruby nozzles offer exceptional durability, precision, and thermal conductivity. They can be used with many abrasive filaments. These nozzles have one problem: they are expensive.

Types Of 3D Printer Nozzle Based On Shape

1. Flat-head

Some nozzles have a flat head through which the filaments can pass. This shape is ideal for projects that require greater durability than speed. There doesn’t need to be much struggle to set the nozzle in place and get the process going.

Flat head nozzles will take longer to cool the filament after it has been ejected.

2. Pointed

The pointed nozzles are a great choice if you value your time and value your 3D printing projects. They don’t demand much time for heat transfer after depositing the filament in place and cools down rapidly.

One potential problem is that you will need extra effort to position the nozzle correctly. This can lead to scratches.


The world of 3D printing has many options. There are many options of nozzles for you to choose from here – be it based on size, material or shape. It all depends on the requirements of your business or project.

When choosing the right size or type of 3D printer nozzle, you should consider four factors: abrasiveness, strength, speed, and thermal conductivity. The extensive guideline below will help you find the best one.
