While 3D printers support the usage of several nozzles, different printers have different nozzle compatibility.
If you don’t want to pick the wrong nozzle, dive in to know which key consideration you need to take into account when changing nozzles.
Are 3D Printer Nozzles Universal?
3D printing nozzles aren’t universal. They craft from different materials and vary in size and diameter. Before you get a 3D printer nozzle, please ensure it suits your printer.
Do All 3D Printers Use the Same Nozzle?
No, 3D printers use different nozzles. You have to determine whether your extruder is compatible with a particular nozzle before purchasing it.
Based on the measurement of your current nozzle, you can determine whether it is compatible with a nozzle you want to replace it with.
You will need to unhinge the hot end filament after heating it to printing temperature. Unscrew your nozzle with a socket wrench.
You can use these ways to determine that the nozzle size of your potential replacement coincidence with that of your current one:
- Fit the threads of the present nozzle to those of the potential replacement. If no space remains, then you can interchange the extruder nozzle.
- Use a caliper (view on Amazon) to determine the replacement’s nozzle thread pitch and diameter
Are Extruder Nozzles Interchangeable?
Yes, extruders have interchangeable nozzles. However, interchangeability also depends on a nozzle’s compatibility with your printer.
There are considerations to factor in when picking a new nozzle.
Will you be using abrasive or non-abrasive filaments? What printing speed do you want to work with?
What layer height do you wish to use?
Provided your new 3D nozzle is compatible with your printer, you can use it.
Are 3D Printer Nozzles Standard?
No, there is a huge difference in various aspects of 3D printing nozzles. Some can print at a faster speed, and others slow. Some are suitable for printing very thin walls, while others are not.
These nozzles typically come with a 0.2 to 1.0mm nozzle diameter. Their materials and filament diameter also differ. Check out the consideration factors below for details.
Aspects to Note Before Changing 3D Printer Nozzles
Before changing your nozzles, consider your reasons for doing so. Essential aspects to think about while changing 3D printing nozzles include:
1. Hot End Fitting
The right nozzle for your printer has to fit its hot end. Most nozzles may appear similar though there are several differences.
It is imperative to ensure the nozzle fits the hot end as failure will result in leaking that will destroy your print.
2. Nozzle Diameter
Typically, 3D printers come with a standard nozzle with a nozzle hole diameter of 0.4mm. These nozzles are neither too large nor too small for good print quality. Using slightly larger or smaller nozzles may not be a big issue.
3. Smaller Nozzles
Replace the standard nozzle with a 0.3mm size nozzle if you want more intricate prints. The smaller your 3D printing nozzle is, the more detailed the print.
However, going for a smaller nozzle is not always best. Overly small nozzles offer the filaments a tiny space to extrude. Due to this, contaminants may obstruct your nozzle end.
Nozzle hole clogging may also arise from low-quality filament usage.
A non-plastic filament, say wood, metal, or glass, may clog the hole as well. And cleaning small nozzle heads is pretty challenging.
While smaller nozzles take more time to print than standard nozzles, they provide better quality prints. A smaller nozzle is excellent for leisure printing and jobs demanding highly detailed prints.
4. Larger Nozzles
While you may sacrifice a high level of intricacy, a large nozzle has its advantages. One is you’ll spend less time printing as they extrude faster in one movement. A larger nozzle also allows you to print taller layers.
There are several nozzles larger than the standard 0.4mm nozzle. You can opt for a 0.6mm or a 0.8mm nozzle. Some brands are even producing 1.2mm nozzles.
A 1.2mm nozzle allows you to print thrice as fast as the standard nozzle. Additionally, the larger the volume of extrusion, the stronger the bonding of filament.
It is more difficult for contaminants to clog a larger nozzle head than a smaller one.
On the downside, your print will have less refined details. You also need to adjust the heater block with your nozzle.
Having a large nozzle may result in your filament not heating adequately before extrusion. This results because the filament passes your heat block faster.
You can solve filament heating issues by using a volcano heater block.
Large nozzles are ideal for heavy usage.
5. Nozzle Shapes
Two nozzle head types exist based on nozzle length:
Filaments from long nozzles travel long distances and cool more in the process. Those extruding from short nozzles cool less.
The temperature of the extruded filament affects the print quality. Long nozzles result in ridged prints given the quickened filament cooling.
There are also narrow and broad nozzles. There is a noticeable change in the print’s exterior when using a broader nozzle head. Broad nozzles also tend to result in less intricate 3D prints.
Narrower nozzles are suitable when producing highly detailed prints. However, it may be challenging to use narrow-headed nozzles on low-layer heights.
6. Nozzle Materials
Continuous filament extrusions gradually destroy 3D printing nozzles. Because of this, you may notice a decline in your print quality over time.
If you want a nozzle for regular 3D printing, go for one that crafts from hard materials.
So, what are the materials used for 3D printing nozzle creation?
a) Stainless Steel Nozzle
If you are looking for tough nozzles, stainless steel nozzles may be exactly what you need.
While stainless steel is tougher than brass, it’s not as thermally conductive as the latter. Because of this, they are more prone to blocking.
Though this nozzle material is pricier than brass, a stainless steel nozzle is much more durable.
What is Stainless Steel Nozzles Best for?
These nozzles are suitable to print abrasive materials.
If you like using carbon fiber, glass, metal, and other abrasive materials, consider getting stainless steel nozzles.
b) Hardened Steel Nozzle
These nozzles are better when you want to handle abrasive filaments than other nozzle types.
Although hardened steel nozzles eventually decay like other nozzle types, they do so at a slower rate.
Filaments sometimes have small particles and carbon fibers that may damage softer nozzles such as brass. A hardened nozzle is better suited in such instances.
Although you spend more to get hardened steel nozzles than brass nozzles, they are still affordable.
The primary shortcoming of these nozzles is their poor thermal conductivity. Because of this, you may have extrusion issues. This becomes challenging, especially when dealing with larger nozzle diameters.
Therefore, you have to watch out for the heating temperature.
What are Hardened Steel Nozzles Best for?
Hardened steel nozzles are excellent for overly abrasive 3D printing filaments like copper, nylon, and steel. If you want to print tough and highly durable products, these may be the best nozzles for the job.
c) Brass Nozzle
Brass nozzles are the standard nozzles for 3D printers. Often, a new 3D printer nozzle comes with brass construction.
The first reason for the brass nozzle’s popularity is its considerable heat conduction capabilities. This feature enables a brass nozzle to retain the right extrusion temperature better.
While brass is softer than some nozzle materials, it still has the right material strength for nozzle making. Its softness contributes to its ease of manipulation.
Another reason why brass nozzles are common is their ease of availability and affordability. You can get many brass nozzles ranging from six to ten dollars.
Brass nozzles are resistant to scratches and durable. A brass nozzle may be suitable if you are an intermediate 3D printer user.
What is Brass Nozzles Best for?
Brass nozzles are excellent for use with plastic filaments. It’s best to avoid abrasive filaments like metal, glass, wood, or nylon. The constituents of abrasive materials quickly shorten the lifespan of a brass nozzle.
d) Ruby-Tipped Nozzles
These nozzles come from brass, with the only difference being the ruby tip. And this offers 3D printer fanatics some advantages.
Most of the nozzles coming from brass mean that a ruby nozzle has good thermal conductivity. Yet, being ruby-tipped, it can handle abrasive materials challenging to use with purely brass nozzles.
That said, only the tip of the ruby-tipped nozzle is highly damage-resistant. The rest of its body is more susceptible to destruction given the brass construction.
A ruby nozzle also is generally pricier than steel nozzles. Of course, with a precious stone at the tip of the nozzle, you won’t pay the same as you would with regular materials. While a hardened steel nozzle costs an average of $20, you will spend about $90 for a ruby-tipped nozzle.
What are Ruby-Tipped Nozzles Best for?
Ruby-tipped nozzles offer you the versatility to 3D print with soft and abrasive filaments plus those with carbon fiber.
They are excellent if you want to enjoy the benefits of steel and brass nozzles simultaneously.
e) Other Materials
Some nozzles come from tungsten, copper, and aluminum. These also have their ups and shortcomings.
Brass and steel nozzles have aspects that suit most 3D printing usages. You can always consider their attributes, and depending on what you need, you can pick suitable options.
Why Interchange Nozzles?
While some nozzles are superb for precision printing, others are best for high-speed 3D printing.
Below are reasons for interchanging nozzles:
- You may need to print at a faster speed. You can therefore change to large nozzles sized 0.6mm or more.
- When you need better quality print, you should swap large nozzles with those that can handle standard filaments or even smaller ones.
- A smaller hole tends to clog faster. You may need to replace such nozzles frequently.
- You need to use abrasive materials, so you switch from brass to hardened steel nozzles. Pick standard or larger nozzles.
- If you need temperature accuracy, you can change to brass nozzles.
- When printing food products, you can switch to stainless steel nozzles.
Yes, and as you change nozzles, consider your application.
You wouldn’t want to get a large nozzle diameter when producing high-resolution prints. Picking the right nozzles helps you avoid extrusion issues.
