Single Vs Dual Extruder 3D Printer – Which One to Choose?

Stepping into the sphere of 3D printing, you’ll shortly be facing a situation where you have to choose between a single extruder and a dual extruder 3D printer.

This dilemma can be confusing, but fret not, because this article will guide you in making the best choice that suits your printing needs.

A single extruder 3D printer is simplicity at its best. There are no complications involved and beginners will quickly get used to this type of a 3D printer.

A dual extruder, on the other hand, is complex yet offers a ton of functionality and provides you with versatile options. However, it all boils down to personal preference in the end.

We’re now going to further the topic in detail from top to bottom, so keep on reading for a more comprehensive answer.

From the pros and cons to the best single and dual extruder 3D printer, what follows will assist you in making the perfect decision when purchasing.

Single Extruder vs Dual Extruder 3D Printer

Many people start simple with 3D printing, and get a printer that has a single extruder.

What does this mean?

With a single extruder 3D printer, you’re going to print with one filament at a time.

This is convenient, swift, and gets the job done in an efficient manner. There are no additional messes, and cleaning is minimal, unlike dual extruder 3D printers.

The ease of use is one of the major reasons why single extruder printers are flourishing in the industry today.

However, if a dual extruder is interesting you more, do realize that this decision will cost you extra, and can seem overly complicated at first. Despite the downsides, printers with a dual extruder offer some of the best creative options, and extensive capabilities to date.

To the core, a second extruder along with a first one means that you have a whole new space for another filament, may that be a support or purely a thermoplastic.

A separate slot for the filament gives rise to diversity here. Multiple features are now available at your disposal. This refers to the fact that you can use two different colours for your object, giving it a charming look like no other.

Moreover, you could print using one filament, but use another stronger filament to reinforce your printed object. There’s also the prospecting of using a support filament like PVA along with a material like ABS.

This combination gives you an advantage that determines the overall look of the object. To begin with, you won’t notice any unpleasant support marks left on the print after you’re finished.

This, in turn, is highly unlike single extruder 3D printing, where using support items like rafts and skirts are necessary at times, but require hefty post-processing to maintain quality.

Nevertheless, 3D printers that offer dual extrusion are a cut above single extruder printers in terms of pricing. Furthermore, when you think of cleaning up after the print, a dual extruder printer is double the trouble.

Single Extruder 3D Printers

We’re going to take a brief look at what printers with single extrusion have to offer, and where they fall prey to dissatisfaction.

The Pros

Single extrusion 3D printers aren’t thoroughly praised for nothing. Let’s break down where they typically excel.

Print Easy

Single extruder printers are beginner-friendly, owing their facile practicality to a single nozzle.

These types of printers are highly recommended for people who have just started out with printing since you’re always going to find your way with them.

Calibrating Single Extruder Printers

The Z-alignment of such printers are effortless to establish, and is set up in no time. Since there is only going to be a single nozzle that you’ll have to worry about, things are going to be a lot easier.

Calibrating pressure settings of the printer is also easy to achieve, and users have reported the process being a breeze. However, slight variations in difficulty might occur from printer to printer.


A single extruder 3D printer is perfect for those wanting to print with only one colour.

Of course, there are people out there who wouldn’t want messing around with complicated stuff, and just want to print away and get the job done.

These printers shine in such situations, being free of hassles found in a dual extruder printer, and offer the user a smooth printing experience.

The Cost

You can get great single extruder 3D printers for cheap prices on the market. As the printing industries are evolving day by day, the race for developing the cheapest and most efficient printers continues as the days go by.

You’re easily going to find a single extruder printer that works for you, and isn’t going to cost that much either.

As single extruders work with a single filament, there’s no need to buy a second one which you would have been doing otherwise if working with a dual extruder.

Therefore, 3D printing expenses are significantly cut back as filament costs are something to consider too when buying a printer.

The Cons

Single extruder 3D printers make quite an impression, but there are some aspects to them where many would disagree to make the purchase.


While you can get to considerable heights printing with a single extruder 3D printer, you’re still going to be very far from what dual extruders have to offer.

Single extrusion 3D printing has its limitations, therefore, and the foremost being that you can’t use multiple filaments at once. You’re bound to a single colour scheme, only one nozzle diameter to work with, and furthermore, a single filament.

This basically holds you back from achieving the true potential of 3D printing, where you could form world-class prints of the highest quality.

The bottom line?

This mode of printing is truly simple and does not leave room for innovation on the next level.

Support Filaments

Filaments are of several different types. One of them is a support filament that accompanies you drastically when making complex prints.

You cannot use a support filament with single extruders because there’s just no space for it.

Instead, you use support items like rafts, brims, and skirts. Although helpful, there are certain downsides to using them. Support items applied to objects in single extrusion will demand extra finishing while leaving traces of the support on the print.

This can sometimes ruin your object if things go wrong. Support items are only recommended when they are absolutely needed, hence.

Dual Extruder 3D Printers

Labelled as a very effective method to fulfil your 3D printing tasks, dual extruder printers have positives and negatives both. You’re going to get a descriptive idea below.

The Pros

Dual extrusion type of printing is known for the quality it produces. Let’s affirm the advantages of owning a dual extruder 3D printer.

An Open-World of Diverse Options

Dual extrusion printing opens the door to a plethora of possibilities, increasing range and dynamism.

It gives you the ability to switch between printing materials on the go, leaving any labour-intensive process out.

Dual extruder 3D printers come especially handy when you need to make a part with multiple colours. The second nozzle is there to do just that, along with a few more great functions.

These printers provide you with the broad range of options you need, if you’re a critical thinker with hopes of achieving truly commendable objects.

For instance, with the help of a dual extruder, you can form prints that incorporate many materials of different essences.

You could make wearable items that are flexible in some areas, and compact in others. In other words, dual extruders let you make different blends of materials that have varying properties.

Great Support Usage

With a highly specialized second extruder at your disposal, the possibilities on how to use it skyrocket.

One important feature of dual extruder 3D printers is how you can seamlessly use support filaments accompanied with another thermoplastic to make prints.

There are water-dissolvable support filaments, like PVA, out there that deliver profoundly per their function, and do not leave their marks or any smudges after their removal.

Let’s see how they do that.

Normally, support items like brims and skirts used on an object is really troubling. Even before you begin, you have to look out for certain settings like layer height, etc., and after you’re done, removing the support leaves your print in ruin.

To compensate for that, you usually have to do some extra post-processing to make the print look presentable and professional. Talking in terms of dual extrusion, support items or filaments being a struggle is a thing of the past.

You just have to slot in a second, support filament in the other extruder of the printer, and see how it manages from there.

For instance, PVA is a thermoplastic material that dissolves in water and is actively used as a support filament in dual extrusion. The fact that it’s water-soluble, and efficiently works with the dual extruder 3D printer, is what takes the cake.

PVA isn’t removed from the printed object. Instead, it’s broken down while submerged in a pool of water heated to about 60°C. The support filament on the print deteriorates within half an hour and leaves you in admiration.

What you’re going to see afterward is a fresh, immaculate print that excludes any distortions or overhangs usually observed when printed with single extruders.

Multi-Colours, Stronger Prints, and More

This ability of dual extruder 3D printers that let allows them to print in two different colours at the same time has gained immense popularity in anatomical and vehicular domains.

When you need some distinct parts of your printed object to be highlighted more, dual extrusion comes in and steals the show.

There’s also a physical convenience assorted here, as normally you would have had to change colours in the middle of the print manually, which can be quite bothersome.

With the addition of another extruder, you can begin your print with two colours, making the process streamlined for you.

Another quality feature you’re going to admire is toughening your print with a variation of materials. For example, a print made out of a flexible material like HIPS, and a sturdy thermoplastic, mainly a polycarbonate, offers you unprecedented creativity, and diversity in your prints.

To top it off as a bonus advantage, dual extrusion lets you print two identical objects at the same time- one with each extruder.

This process is called Ditto Printing, but be sure there is an appropriate distance between the dimensions of the two nozzles.

The Cons

There’s a possibility that a dual extruder 3D printer might not be the one for you. Let’s see how.

You May Not Need It

There are some amazing single extruder 3D printers out there that many people prefer, and think them fit to be the machine for the job. In turns out, you might never need the capabilities and the extensive functionality of a dual extruder 3D printer.

Since we know how effective single extruders can be, dual extrusion printing offers its own touch of brilliance, but if you’re trying to keep it simple, a dual extruder may not be worth your money.

The Additional Expense

It’s great that the printer you’re thinking of going to buy is a dual extruder. But did you know that these machines cost a lot more?

With a second extruder nozzle equipped, it’s apparent that you’ll have to get a second filament as well. This added expense can sometimes be a lot to handle.

Single extruders, on the other hand, can be bought for as low as $200, and pack a lot more punch than their price. Dual extruders, however, will cost considerably more if you’re looking for a good one.


It’s fairly known how extruders of a printer require care and maintenance once in a while. The nozzle could end up getting clogged, or multiple problems with the hot end could arise.

Printers with a dual extruder, therefore, are prone to twice the issues. You have two hot ends and two nozzles that need to be taken care of after every other week or so.

Should You Choose A Single or A Dual Extruder 3D Printer?

The answer to this conundrum lies in personal preference. The facts are there for you to comprehend, and to take the decision consequently.

If you’re a simple person looking to make simple prints, an affordable single extruder 3D printer can set you up for good.

These are more popular as well. Their fame roots from positive feedback from beginners and hobbyists.

If I was just starting out with 3D printing, I’d go for a single extruder with my eyes closed. It’s just that simple.

However, if you’re an experienced fellow closely knowing the ins and outs of 3D printing, your practical knowledge and a dual extruder 3D printer will flow together quite cordially.

Moreover, if you’re working on a project that requires a multi-coloured product and a blend of different thermoplastics, a dual extruder will fit perfectly here as well.

In the end, it’s only sensible to advise that if you’re a newcomer to this business, put your faith in a single extruder 3D printer.
