How often should you change 3D printer bed?

You can get away with leveling the bed every 5-10 prints depending on how stable the bed is and how careful you are when removing the finished prints from the surface. In order to stay on the safe side, it is advisable to level the bed before a large print (15 hours or longer) to ensure that it doesn’t fail mid-print.

How long does Ruby nozzle last?

As you can imagine, ruby nozzles are significantly more expensive than brass and steel nozzles. The Olsson Ruby goes for around $100 (for 1), but it’s said to last forever.

How do I know if my nozzle is worn out?

To the untrained eye, a worn-out 3D printer nozzle looks just like any. However, if you look closely, you’ll see the signs of wear and tear.
…
Signs of Nozzle Damage

Marks and grooves in the inner walls near the opening.
Bigger nozzle diameter than usual.
Nozzle tip has become dulled down or shortened.

How do you know when to replace nozzles?

In short; The nozzle type you use (brass, steel or ruby-tipped) and the hours your printer is running every day will determine the lifespan of the nozzle; If you print once or twice a week, a brass nozzle will last 3-6 months, but if the printer is running 24/7, it will need replacing every month or so.

How do you clean PLA off nozzles?

First, clean the nozzle using a damp cloth or an alcohol wipe while the nozzle is hot. This may cause some steam but will indeed remove any material clinging to the nozzle. If this doesn’t work, you can also use a wire brush, small blade, or needle to remove any remaining debris from the nozzle.

How often should I clean my extruder?

Clean your extruder after every job

This is the most straightforward thing you can do to avoid clogs. Simply remove your extruder and use a toothpick-sized object to clean out any fragments of material left inside. You might also consider periodic cleaning with acetone.

How many hours do 3D printers last?

It’s difficult to give a specific value for lifetime hours for a 3D printer but based on my research from reading user experiences, I’d give a range of 7,500 printing hours to 15,000 printing hours (printing for 4 hours everyday for 10 years).

What is the best nozzle for PLA?

If conventional materials are used, such as PLA or ABS and pieces of intermediate size the ideal is to use a Brass Nozzle 0.40 mm. If you want to make small pieces with a lot of detail we recommend a Brass Nozzle 0.25 mm and for the opposite case, for large pieces a Brass Nozzle 0.8 mm.

Do I have to level my bed after every print?

If I level the bed afresh before printing, then I always get a good print. If I don’t level the bed, then the print will always fail on the first layer. Time between prints doesn’t matter. iI can be two minutes, or several days.

Do you need to level a 3D printer?

Whether you’re using a brand new 3D printer for the first time or noticing that your prints come out uneven or, even worse, fail to stick, you need to level the print bed.

How long does a brass nozzle last with PLA?

Glo in the Dark you can expect minutes of printing will ruin a brass nozzle (100g grams destroyed my first brass nozzle); standard unfilled PLA/PET expect a year or more; Glass, carbon, glo, and metal filled plastics will eat the nozzle from the inside, and entirely depends on the hardness and print volumes.

Is a ruby nozzle worth it?

Conclusion. Ruby-tipped nozzles are indeed worth every penny. They are designed to handle tough, abrasive materials like carbon fiber without sacrificing precision, and they will not easily wear out even under high-frequency use.

How does nozzle size affect 3D printing?

A larger-diameter nozzle lays down wider perimeters, which means that it uses fewer perimeters than a smaller-diameter nozzle to print a wall of the same thickness. A nozzle with a larger diameter also allows for printing with increased layer height. Combining these two effects leads to a noticeably shorter print time.

How long does a brass nozzle last with PLA?

How long does a 3D printer last?

With proper use and maintenance, an Ender 3 should last you at least 5 years of printing, up to 10+ years. Your 3D printer lifespan will depend on how well you maintain it and how often you use it.

How do I clean a 3D printer nozzle?

Solutions. First, clean the nozzle using a damp cloth or an alcohol wipe while the nozzle is hot. This may cause some steam but will indeed remove any material clinging to the nozzle. If this doesn’t work, you can also use a wire brush, small blade, or needle to remove any remaining debris from the nozzle.

How Often Should You Change 3D Printer Nozzle?

3D printer nozzles are consumables used, mistreated, and replaced several times throughout a 3D printer’s lifetime. How often should you change the 3D printer nozzle is the question.

After giving this subject some thought, I decided to seek out the best answers and share them with you.

When poor print quality persists despite routine maintenance, your nozzle will most likely need replacement.

Some customers have replaced the nozzle on their 3D printer six times in three years. Yet, they start printing with new filament every three months, necessitating nozzle changes every three months.

How Often Should You Change 3D Printer Nozzle?

When Should You Replace/Change Your Nozzle?

Although there is no set time frame for changing or replacing your nozzle, we recommend that you do so every 3-6 months. Replacement time is very dependent on how frequently you use your 3D printer, the type of filaments you use, and the quality of your nozzle.

A high-quality, pricey nozzle built for long-lasting smooth printing is much more likely to last you more printing hours than a low-cost, Chinese-made brass nozzle.

The factory brass nozzles that come with 3D printers are typically inexpensive, allowing the overall price of the 3D printer to be competitive.

The Nozzle Set is a good set of nozzles that will last an extended period. It is trendy and occasionally sells out, so check the website to see if they are still available.

You do not only get a variety of brass nozzle sizes and a storage box. But it’s also the best-selling item, owing to its superior quality and low pricing.

Compatible with MK8 extruders, including the Ender 3, Creality CR-10, MakerBot, Prusa I3, etc.

You may always upgrade your printer’s nozzle to something of more outstanding quality, and I’ll describe which ones are good later in this piece.

Because your 3D printer may create successful prints following successful prints, you shouldn’t change your nozzle unless you notice evidence of print quality degradation.

This is so you can get the most out of each nozzle’s printing hours and avoid having to replace nozzles sooner than necessary. This may not be the best method if you’re doing long, complex 3D prints because it could destroy the entire print.

If your printer has a resume printing capability, your layers aren’t appropriately finished in the middle of a print. You can change the nozzle; your print may not restart to a print that ends appropriately.

How Do You Replace & Install a Nozzle on a 3D Printer (Ender 3 Pro/V2)?

To change and install a nozzle for your 3D printer, you should first remove the main fan shroud on the print head to access the heat block and nozzle. Heat the nozzle to average temperature and turn the printer off. You can then use pliers to hold the heater block while using a wrench to remove the nozzle.

Tighten the nozzle until a reasonable amount of resistance is felt. It doesn’t have to be extremely snug. Some individuals use a 3nm nozzle torque wrench to ensure they don’t overtighten the nozzle, but this isn’t required.

This is the conventional method. However, it isn’t the greatest because many people burn their fingers by accidentally touching the hotend.

A professional option now works almost too well, and several users have come to appreciate it.

The ZCatch 3D Printer Nozzle Removal Tool, available on Amazon, is a terrific addition to your 3D printing toolkit. It was explicitly designed to allow users to quickly swap out 3D printer nozzles.

A 10-piece 14 Vanadium Chrome Socket Set, 1-ZCatch Decal, and an instruction manual are included with the removal tool. Because it works so well, product reviewers only have good things to say about it!

It’s a gadget that makes replacing the nozzle on your 3D printer a breeze. When removing the nozzle, you won’t have to fight to acquire a firm grip on the heat block with pliers.

This tool secures the heater block in place with a few simple twists while removing the nozzle. You may need to do so in some circumstances because you don’t have the best leverage to hold the hotend, but you can easily remove the nozzle once it’s loose.

Rather than balancing the nozzle and keeping it grasped, it has a lovely place where it can slip into.

What Are the Signs That My Nozzle Is Worn Out?

There are several techniques to determine whether or not your nozzle is worn out. Some aren’t quite thorough, but it’ll usually suffice if you can notice the indicators.

How Often Should You Change 3D Printer Nozzle?

Checking Your Nozzle Visually

Method 1:

The first method I recommend for determining whether your nozzle is worn out is visually inspecting it. It will help if you look for changes between how the nozzle was new and now. The critical difference you’re looking for is the diameter size.

Suppose the size of the hole on your nozzle has become more extensive. In that case, it’s a solid indication that your nozzle is wearing out and not generating the most outstanding quality prints. You may not notice this visually, but you can perform a short test to see if this is the case.

Get a set of tiny drill bits and try fitting one of the more significant drill bits into your nozzle hole to test it.

If a 0.5mm drill bit fits into a 0.4mm nozzle, you know your nozzle has substantial wear, which will most likely result in a reduction in print quality.

Method 2:

The second way to inspect your nozzle is to look for ridges, grooves, curves, marks, lumps, or anything else you can find on it.

Because your nozzle will most likely be worn out on the interior rather than at the tip, being able to observe deterioration in the nozzle’s material is critical.

It indicates that your nozzle is deteriorating, resulting in unpredictable and irregular stacking. You’ll probably still be able to print effectively, but your nozzle is towards the end of its life cycle and will need to be replaced shortly.

This is related to the nozzle diameter; however, if the tip of your nozzle becomes rounded, you know it’s towards the end of its life. Abrasive materials will change the geometry of a nozzle, causing it to lose its sharpness at the tip.

Because the height of the nozzle and the bed are out of equilibrium over time, it might produce adhesion concerns. This one is a little simpler to find, so keep an eye out for it and prepare a replacement if you come across it.

Use the Straight Extrusion Test

Use This test to see if your extrusion is straight.

You may perform this simple test to see if your nozzle is worn out. Pull your print head to the side, away from the bed, and allow your printer to extrude. You want to see a spurt of plastic straight down when this happens.

It’s excellent evidence of nozzle damage if you see the plastic bending and weird or extruding in one direction and curving around.

How to Extend the Life of Your Nozzle

We know how often to change it and identify if it’s worn out. Now we can move on to making sure your nozzle gets the maximum life possible.

The most straightforward piece of advice for extending the life of your nozzle is to avoid abrasive filaments like carbon fiber, exotic and composite filament, and some kinds of glow-in-the-dark filament.

These filaments have qualities that cause them to react poorly with some nozzle materials over time, with some being significantly worse than others.

Basic filaments such as PLA, ABS, and PETG are usually free of these issues because they are non-abrasive and relatively smooth.

They’re not just abrasive, but they’re also more likely to cause frequent filament feeding issues, such as clogging and jamming.

You can avoid these typical issues and make your nozzle last longer if you learn a few excellent 3D printer maintenance techniques.

To extend the life of your nozzle, follow these steps:

3D printer flushing with a filament cleaner sponge

De-gunk your 3D printer regularly.

Clean up the accumulation of materials in your printer by disassembling it from time to time.

Using these approaches in conjunction with a high-quality nozzle can result in a nozzle with a lengthy life span and multiple successful prints.

This is often the difference between someone who enjoys 3D printing and achieves fantastic results and who is continuously frustrated with 3D printing and lacks the skills to solve some issues.

Don’t be afraid to clean your nozzle, extruder, and printer thoroughly.

What Happens If Your Nozzle Is Worn Out When You Print?

Setting your slicer’s nozzle diameter to a larger size than your actual nozzle, setting your bed level too high, or printing with a partially blocked nozzle are all examples of 3D printing with a worn-out nozzle.

In some circumstances, your print may still finish without significant variances. Still, your print will have numerous faults that you should avoid at all costs in most cases. Under-extrusion, poor layer adhesion, rough surface finishes, and blobs of material around your print are all examples of this.

What Nozzles Do 3D Printer Users Use the Most?

Nozzles come in various materials, the most common brass, including stainless steel, toughened steel, and even ruby.

If you plan on printing with abrasive filaments or want a high-quality nozzle in general, get a Hardened Steel Nozzle. Because of its thermal conductivity and ease of fabrication, brass is commonly utilized in 3D printers.

You may get a Micro Swiss Plated Nozzle from Amazon instead of sticking with brass. They are reasonably priced, and users have expressed satisfaction with the quality of these nozzles.

Check out my article 3D Printer Nozzle – Brass Vs. Stainless Steel Vs. Hardened Steel for more information on the best nozzle to use.

They not only last longer, but they have also been shown to increase the overall quality of your print while producing more minor printing troubles. When it comes to upgrading from a factory nozzle that came with your 3D printer, it’s a no-brainer, so do it today.

After reading this article, you should better understand nozzle maintenance, the best nozzles, and when to change your nozzle.

Top 7 Frequently Asked Questions about 3D Printer Nozzles

When should I replace my Ender 3 nozzle? The nozzle’s lifespan depends on the type of nozzle you choose (brass, steel, or ruby-tipped) and the number of hours your printer runs each day. A brass nozzle will last 3-6 months if you print once or twice a week, but if the printer is on all the time, it will need to be replaced every month or so.

Check our the Top 7 Frequently Asked Questions about 3D Printer Nozzles post for the other questions and more details.

When & How Often Should You Change Your Nozzle On Your 3D Printer? – 3D Printerly

Nozzles on a 3D printer are a consumable that gets used, abused and replaced many times in a 3D printer’s lifespan. The problem is, when should you be changing your nozzles over?

After wondering about this question I decided to search around for the best answers and share it with you guys.

When you notice lower quality prints, when maintenance doesn’t improve things your nozzle is most likely due for a replacement.

Some people have changed their 3D printer nozzle 6 times in 3 years, but start printing with a new filament and require nozzle replacements every 3 months.

If you are interested in seeing some of the best tools and accessories for your 3D printers, you can find them easily by clicking here (Amazon).

How Often Should You Change/ Replace Your Nozzle?

There isn’t a specific time frame in which you should change or replace your nozzle, but generally you should change your nozzle every 3-6 months. This really depends on how often you are using your 3D printer, what kind of filaments you are using, and how high or low the quality of your nozzle is.

If you have an expensive, high quality nozzle, designed for long-lasting smooth printing, it’s a lot more likely to last you more printing hours than a cheap, Chinese manufactured brass nozzle.

3D printer users that only 3D print with low temperature PLA could technically use one brass nozzle that lasts for years and have great results throughout.

In some cases, you may have leveling issues where your brass nozzle scrapes against the build plate and wears out, so it would need replacing sooner.

The factory brass nozzles that come with 3D printers tend to be fairly cheap so that the price of the 3D printer overall is competitive.

A good set of nozzles that last a long time is the LUTER 24-Piece Brass Nozzle Set from Amazon. It is very popular and sometimes runs out of stock so check the link to see if they are available.

Not only are you getting a wide range of brass nozzles sizes with a storage box, it’s also the highest rated on Amazon, mainly because of the premium quality and the great price.

Compatible with MK8 extruders such as the Ender 3, Creality CR-10, Makerbot, Prusa I3 and many more.

You always have the choice of upgrading your printer’s nozzle to something of a higher quality, which later in this post I will explain which ones are good. The usual response here is, if it ain’t broke, don’t fix it.

Your 3D printer may produce successful print after successful print, so generally you shouldn’t need to change your nozzle until you actually see some evidence of print quality being affected.

This is so you can maximize the printing hours of each nozzle and not throw out nozzles earlier than you needed to. This may not be an ideal strategy if you are someone who does long, complex 3D prints because it could ruin the whole print.

You may have a resume printing function, but if your layers aren’t done adequately in the middle of a print, and you switch out the nozzle, your print might not get resume to a print that finishes properly.

How Do You Change & Install a 3D Printer Nozzle (Ender 3 Pro/V2)

To change and install a nozzle for your 3D printer you should first remove the main fan shroud on the print head to access the heat block and nozzle. Heat up the nozzle to normal temperature and turn the printer off. You can then use pliers to hold the heater block while using a wrench to remove the nozzle.

Some people use a nozzle torque wrench of 3nm to make sure they don’t over tighten the nozzle but it’s not necessary. Just tighten the nozzle until you start to feel a decent amount of resistance. It doesn’t have to be very tight.

This is the standard technique, but it isn’t the best since many people manage to accidentally touch the hotend and burn their fingers.

There is now a professional solution that works almost too well, that several users have grown to love.

I would recommend getting the ZCatch 3D Printer Nozzle Removal Tool from Amazon, a great addition to your 3D printing tool kit. It was made specially for users to easily change 3D printer nozzles.

The removal tool comes with a 10-piece ¼ Vanadium Chrome Socket Set, 1-ZCatch Decal & Instruction Manual. Reviewers of the product only have positive things to say about it because it works so well!

It’s a tool that makes changing your 3D printer nozzle so much easier. You will no longer have to struggle with getting a good grip with pliers on the heat block while removing the nozzle.

This tool sets the heater block in place while removing the nozzle through a few simple twists. You don’t have the most leverage to hold the hotend so in some cases you may still have to hold the hotend, but once it’s loose, you can easily remove the nozzle.

It has a nice area where the nozzle can drop into, rather than trying to balance the nozzle and keep it gripped.

How Do I Know My Nozzle is Worn Out?

There are a few ways that you can check or know that your nozzle is worn out. Some aren’t 100% thorough, but it will generally get the job done if you can spot the signs.

Checking Your Nozzle Visually

The first way I recommend for checking if your nozzle is worn out is simple by visually checking your nozzle. You want to check for distinctive differences between when the nozzle was fresh and how it is now. The main differences you’re looking for is the diameter size.

If you notice the size of the hole on your nozzle has increased, this is a pretty good sign that your nozzle is wearing out, and isn’t producing the best quality prints. Sometimes you won’t notice this visually, but there is a quick test you can do to check this out.

Get a set of tiny drill bits and check your nozzle by trying to fit one of the larger sized drill bits into your nozzle hole.

If say a 0.5mm drill bit fits into a 0.4mm nozzle, then you know that your nozzle has significant wear that will likely cause a decrease in the quality of your prints.

The second method for checking your nozzle is to check for ridges, grooves, curves, marks, bumps, whatever you can find on your nozzle.

The reason this method works is that a lot of the time, your nozzle will be worn out on the inside rather than at the tip, so being able to see deterioration in the nozzle’s material is important.

It means that your nozzle is wearing away, possibly leading to unpredictable, inconsistent layering. You’ll probably still be able to print successfully, but it means your nozzle is getting to a point where it soon needs to be changed over.

This ties in with the nozzle diameter, but the tip of your nozzle becomes rounded, you know that it’s coming to the end of its life. Abrasive materials will affect a nozzle, and it’s shape, creating a nozzle that is no longer sharp at the tip.

It can lead to adhesion issues because the height of the nozzle and bed will be off balance over time. This one is a bit easier to spot so keep an eye on it and get a replacement ready if you see this.

Do The Straight Extrusion Test

This is a quick test you can carry out to give you a sign that your nozzle is worn out. What you want to do if pull your print head to the side, off the bed and have your printer extrude. What you want to see when this happens is a squirt of plastic straight down.

If you see the plastic bending and wonky, or extruding in one direction and curling around, it’s a pretty good sign of nozzle damage.

How to Make Your Nozzle Last Longer?

Now that we have learned how often to change a nozzle and how to tell if it’s worn out, we can move onto how to make sure your nozzle is getting the most life that it can get.

The simplest piece of advice to make your nozzle last longer is to not use abrasive filament such as carbon fiber, exotic and composite filament or some brands of glow in the dark filament.

These filaments have certain properties that don’t react very well to some nozzle materials over time, and some are definitely worse than others.

Basic filament like PLA, ABS and PETG don’t usually have these type of problems because they aren’t abrasive and are fairly smooth.

Not only are they abrasive, but they are more likely to lead to common filament feeding problems making them get clogged and jammed.

When you pick up a few good practices of 3D printer maintenance, you can definitely avoid these common issues and make your nozzle last longer.

Follow these steps to make your nozzle last longer:

Use a filament cleaner sponge

3D printer flushing

De-gunk your 3D printer routinely

Disassemble your printer from time to time to clean up accumulation of materials

Using these techniques, along with a high quality nozzle can lead to a very long nozzle life which gives you numerous successful prints.

Many times, this is what makes the difference between someone who enjoys 3D printing and gets good results, and people who constantly get frustrated with 3D printing and don’t have the knowledge to overcome some problems.

Don’t be afraid to give your nozzle, extruder and printer a good clean.

What Happens If You Print With a Worn Out Nozzle?

3D printing with a worn out nozzle is the equivalent to setting your nozzle diameter in your slicer to a bigger size than your actual nozzle, setting your bed level too high, or printing with a partially blocked nozzle.

In some cases, your print may still complete without any huge differences, but in most cases your print would see many defects that you would want to avoid at all costs. This can include under-extrusion, bad layer adhesion, rough surface finishes and blobs of material around your print.

What Are the Best Nozzles 3D Printer Users Use?

There are many types of nozzles, the most popular being brass and ranging to materials like stainless steel, hardened steel and even ruby.

Get a Hardened Steel Nozzle if you plan on printing with abrasive filaments, or if you just want a high quality nozzle in general. The reason brass is used so widely in 3D printers is because of its thermal conductivity and ease of manufacture.

Instead of sticking to just brass you can opt in for a Micro Swiss Plated Nozzle from Amazon. They are a pretty good price, and users are definitely happy with the quality of these nozzles.

I have a pretty in-depth article called 3D Printer Nozzle – Brass Vs Stainless Steel Vs Hardened Steel so check that out for more info about the best nozzle to use.

Not only do they last longer, but they have been known to improve your print’s quality overall while causing less printing issues. It’s a no-brainer when it comes to switching from a factory nozzle that came with your 3D printer so get yourself an upgrade now.

If you get stringing with your stainless steel or hardened steel nozzle, you may want to increase your retraction settings. You could possibly decrease the printing temperature slightly, but since the thermal conductivity isn’t as high as brass, this could result in under extrusion.

Now that you’re at the end of the post you should have a better idea of nozzle maintenance, what the best nozzles are and when to replace your nozzle.

Heat up the nozzle to normal temperature and turn the printer off. You can then use pliers to hold the heater block while using a wrench to remove the nozzle.

Some people use a nozzle torque wrench of 3nm to make sure they don’t over tighten the nozzle but it’s not necessary. Just tighten the nozzle until you start to feel a decent amount of resistance. It doesn’t have to be very tight.

This is the standard technique, but it isn’t the best since many people manage to accidentally touch the hotend and burn their fingers.

There is now a professional solution that works almost too well, that several users have grown to love.

I would recommend getting the ZCatch 3D Printer Nozzle Removal Tool from Amazon, a great addition to your 3D printing tool kit. It was made specially for users to easily change 3D printer nozzles.

The removal tool comes with a 10-piece ¼ Vanadium Chrome Socket Set, 1-ZCatch Decal & Instruction Manual. Reviewers of the product only have positive things to say about it because it works so well!

It’s a tool that makes changing your 3D printer nozzle so much easier. You will no longer have to struggle with getting a good grip with pliers on the heat block while removing the nozzle.

This tool sets the heater block in place while removing the nozzle through a few simple twists. You don’t have the most leverage to hold the hotend so in some cases you may still have to hold the hotend, but once it’s loose, you can easily remove the nozzle.

It has a nice area where the nozzle can drop into, rather than trying to balance the nozzle and keep it gripped.

How Do I Know My Nozzle is Worn Out?

There are a few ways that you can check or know that your nozzle is worn out. Some aren’t 100% thorough, but it will generally get the job done if you can spot the signs.

Checking Your Nozzle Visually

The first way I recommend for checking if your nozzle is worn out is simple by visually checking your nozzle. You want to check for distinctive differences between when the nozzle was fresh and how it is now. The main differences you’re looking for is the diameter size.

If you notice the size of the hole on your nozzle has increased, this is a pretty good sign that your nozzle is wearing out, and isn’t producing the best quality prints. Sometimes you won’t notice this visually, but there is a quick test you can do to check this out.

Get a set of tiny drill bits and check your nozzle by trying to fit one of the larger sized drill bits into your nozzle hole.

If say a 0.5mm drill bit fits into a 0.4mm nozzle, then you know that your nozzle has significant wear that will likely cause a decrease in the quality of your prints.

The second method for checking your nozzle is to check for ridges, grooves, curves, marks, bumps, whatever you can find on your nozzle.

The reason this method works is that a lot of the time, your nozzle will be worn out on the inside rather than at the tip, so being able to see deterioration in the nozzle’s material is important.

It means that your nozzle is wearing away, possibly leading to unpredictable, inconsistent layering. You’ll probably still be able to print successfully, but it means your nozzle is getting to a point where it soon needs to be changed over.

This ties in with the nozzle diameter, but the tip of your nozzle becomes rounded, you know that it’s coming to the end of its life. Abrasive materials will affect a nozzle, and it’s shape, creating a nozzle that is no longer sharp at the tip.

It can lead to adhesion issues because the height of the nozzle and bed will be off balance over time. This one is a bit easier to spot so keep an eye on it and get a replacement ready if you see this.

Do The Straight Extrusion Test

This is a quick test you can carry out to give you a sign that your nozzle is worn out. What you want to do if pull your print head to the side, off the bed and have your printer extrude. What you want to see when this happens is a squirt of plastic straight down.

If you see the plastic bending and wonky, or extruding in one direction and curling around, it’s a pretty good sign of nozzle damage.

How to Make Your Nozzle Last Longer?

Now that we have learned how often to change a nozzle and how to tell if it’s worn out, we can move onto how to make sure your nozzle is getting the most life that it can get.

The simplest piece of advice to make your nozzle last longer is to not use abrasive filament such as carbon fiber, exotic and composite filament or some brands of glow in the dark filament.

These filaments have certain properties that don’t react very well to some nozzle materials over time, and some are definitely worse than others.

Basic filament like PLA, ABS and PETG don’t usually have these type of problems because they aren’t abrasive and are fairly smooth.

Not only are they abrasive, but they are more likely to lead to common filament feeding problems making them get clogged and jammed.

When you pick up a few good practices of 3D printer maintenance, you can definitely avoid these common issues and make your nozzle last longer.

Follow these steps to make your nozzle last longer:

Use a filament cleaner sponge

3D printer flushing

De-gunk your 3D printer routinely

Disassemble your printer from time to time to clean up accumulation of materials

Using these techniques, along with a high quality nozzle can lead to a very long nozzle life which gives you numerous successful prints.

Many times, this is what makes the difference between someone who enjoys 3D printing and gets good results, and people who constantly get frustrated with 3D printing and don’t have the knowledge to overcome some problems.

Don’t be afraid to give your nozzle, extruder and printer a good clean.

What Happens If You Print With a Worn Out Nozzle?

3D printing with a worn out nozzle is the equivalent to setting your nozzle diameter in your slicer to a bigger size than your actual nozzle, setting your bed level too high, or printing with a partially blocked nozzle.

In some cases, your print may still complete without any huge differences, but in most cases your print would see many defects that you would want to avoid at all costs. This can include under-extrusion, bad layer adhesion, rough surface finishes and blobs of material around your print.

What Are the Best Nozzles 3D Printer Users Use?

There are many types of nozzles, the most popular being brass and ranging to materials like stainless steel, hardened steel and even ruby.

Get a Hardened Steel Nozzle if you plan on printing with abrasive filaments, or if you just want a high quality nozzle in general. The reason brass is used so widely in 3D printers is because of its thermal conductivity and ease of manufacture.

Instead of sticking to just brass you can opt in for a Micro Swiss Plated Nozzle from Amazon. They are a pretty good price, and users are definitely happy with the quality of these nozzles.

I have a pretty in-depth article called 3D Printer Nozzle – Brass Vs Stainless Steel Vs Hardened Steel so check that out for more info about the best nozzle to use.

Not only do they last longer, but they have been known to improve your print’s quality overall while causing less printing issues. It’s a no-brainer when it comes to switching from a factory nozzle that came with your 3D printer so get yourself an upgrade now.

If you get stringing with your stainless steel or hardened steel nozzle, you may want to increase your retraction settings. You could possibly decrease the printing temperature slightly, but since the thermal conductivity isn’t as high as brass, this could result in under extrusion.

Now that you’re at the end of the post you should have a better idea of nozzle maintenance, what the best nozzles are and when to replace your nozzle.
