Although it's been around for a long time in the professional 3D printing world, one of the newer technologies introduced to at-home 3D printers is dual extrusion which allows users to print with two filaments at the same time, meaning you can mix colors and multiple materials—from PETG, ABS, PLA, and carbon, to metal, wood fill, and multicolor printing filaments—to produce extremely creative projects that can even be created simultaneously.

What is a Dual Extruder 3D Printer?

Dual extrusion in 3D printing refers to the art of printing using different materials, whether you choose different colors or different types of filaments with various effects, such as plastic filaments with metallic, or wooden effects. 

This gives you the ability to make superior and more impressive products, and many professionals, as well as 3D printing enthusiasts, and those who own small businesses, i.e. Etsy shops selling 3D printed creations, swear by it. 

Dual Extruder Printer—Buying Guide

3D printers with dual extruding capacity are, understandably, slightly pricier than single extruders, but it is a major upgrade from the single types, and there are many dual extruder 3D printers on the market at reasonable prices of around US$300-US$400. Since you’ll be spending quite a bit on this impressive piece of equipment, you want to make sure you’re buying the best one for your needs.

Types of Dual Extruder 3D Printers

Though most dual printing machines allow for multi-color printing with different materials, there are two main types of dual extruder 3D printers available:

Independent dual extruder system

IDEX printers have two print heads and two nozzles with each print head able to either mirror the other in mirror mode, duplicate items with duplication mode, or print two completely separate objects.

Dependant dual extruders

These dual extruders have two extruders that are connected and move together to create one object using two different filaments. Two spools are loaded on the 3D printer and the printer alternates using them. These printers have the key advantage of reducing printing time since more print material can be produced than with just a single print head.

Dual Extrusion Printers—Considerations

Here are some other factors to consider why trying to find the best dual extruder 3D printers for your needs.

Print bed

As with regular 3D printers, print beds in dual extruder printers come in heated or non-heated options. A 3D printer with a heated print bed is, understandably, usually more expensive than a non-heated option but a heating plate can offer better print quality by keeping the bottom layers warm and reduce the chances of your prints warping during the printing process.

Print heads

Whereas a regular 3D printer just has one print head, a dual extruder printer will have more than one print head, with either two extruders, and sometimes even three. Some dual extruder 3D printers might have just one print head but a dual nozzle that can use two separate filaments on one print. A dual nozzle is great for printing an object in several materials or colors.

Print volume

Print volume, also referred to as the printing volume or the build volume, is how big an object you can build on any given printer. For an at-home printer, projects that would need a huge build volume would likely involve a printing process that would see the object printed off in separate parts and then stuck together afterward. The average size of a 3D printer with a larger build plate would be around 300 x 300 x 400mm.

Calibration

If you’re a beginner to the world of 3D printing, a printer with automatic calibration is highly recommended. As with most aspects in 3D printing, calibrating a 3D printer has a learning curve and an automatic calibration feature can save you time and hassle and do the hard work for you.

Other factors

Another consideration you may want to keep in mind is cost. A dual extruding printer will be priced higher than a regular single head printer, plus maintenance costs will be higher, too, because there are more parts to this machine. In addition, if you’ll be working with various filaments at the same time (or even the same filament but with two extruders), factoring in higher costs for different materials is also a must.

Some machines even come with an added laser engraver feature or you could buy a compatible laser engraver to use with it. Whatever you’re after in a dual extruding 3D printer, our below list has some of the best models on the market to suit an array of styles, needs, and budgets.

Best Dual Extruder 3D Printers and Their Benefits

When they first appeared in the market, FDM 3D printers were only able to print with one filament at a time. More sophisticated multi-color or multi-material projects used to be a real challenge, requiring serious user skills. But demand creates its own supply, and a new technology to solve the problem couldn’t but come up. Thus dual extrusion printers entered the market, breaking new grounds for customers.

This is Top 3D Shop, and in this article, we are going to dwell upon the types and peculiarities of dual extrusion, and find out how to choose a 3D printer offering this function.

 

Is dual extrusion worth it?

The answer to this question, like always, depends on your particular printing tasks. Generally, if you are going to print mostly single-color and single-material models with relatively simple geometries, you can get by with a single extruder device; although even in this case dual extrusion can be of some help. For more complex projects, dual extrusion 3D printers prove definitely useful, if not indispensable in some cases.

 

What are the benefits of a dual extruder 3D printer?

There are two main types of dual extruder 3D printers, based on the use of dependent or independent extruders. We will discuss each type in detail a bit later, and now let’s see how customers can benefit from using a dual extrusion machine.

Pros

Support structures. Virtually, the most important advantage of a dual extruder is its ability to print supports with soluble filaments. Some complex models with overhanging elements require support structures to prevent deformation while printing. With a single extruder, supports are printed with the same filament as the model, and then removed with the risk of damaging the part. Besides, some models need internal supports, which are impossible to remove after the part has been printed. Using the second extruder for printing supports with a soluble filament solves this problem.

The most common materials for support structures are PVA and HIPS. Once the part is ready, all you need to do is just submerge it in water or limonene (if HIPS is used) to completely dissolve the supports. This reduces post-processing time and eliminates the risk of damaging the part.

Multi-color printing. Dual extruder printers allow printing with two filaments simultaneously, creating dual-color parts without the need to change filaments.

Multi-material printing. The second extruder can be used not only for creating support structures, but also for printing dual-material models, combining different properties of both materials used. For example, you can print certain elements of the model with a carbon fiber-filled filament, thus strengthening the whole structure, while the rest of the part can be printed with less expensive PLA. Some 3D printers, like Creatbot D600 Pro, use two extruders for different filament types: the left extruder for printing low-temp materials, such as PLA or ABS, and the right one — equipped with a 420 °C hotend — for printing high-temp nylons, carbon fiber-filled thermoplastics, and PC.

Increased speed. The use of two extruders allows speeding up the process, compared to single extrusion printing. With an independent dual extruder you can double the production volume of your 3D printer by making two similar parts in one go, using mirror or duplication modes.

Minimized downtime. If one extruder is clogged, you do not have to stop printing immediately, but can continue with the second extruder, thus minimizing downtime and increasing the efficiency of the printing process.

Besides a great number of obvious advantages, dual extrusion has its shortcomings, though not numerous.

Cons

High price. As dual extrusion printers are more complicated mechanisms, consequently, they are more expensive than their single extruder counterparts.

Heavier weight. The dual extruder adds some weight, which can interfere with the smooth print head movement and lead to printing failures, like stringing issues. To avoid this, you have to slow down the printing speed.

Maintenance. Dual extruder printers need more frequent maintenance and more complicated calibration than devices with a single extruder. They also require a bit more preparation of the digital model, as you have to specify the printing tasks for both extruders.

 

How to pick a dual extruder 3D printer

There is a large variety of dual extrusion 3D printers in the market, which differ greatly in functionality and, certainly, price range. To make the best of the technology and not to pay extra, it is worth knowing which types of dual extrusion 3D printers are available in the market, and what each type is capable of.

 

Types of dual extruder 3D printers

Dependent dual extruder system

The dependent dual extrusion system has two variations, implying the use of one or two nozzles.

Single nozzle. Such systems are equipped with two extruders using one print head with a single nozzle. The filaments print in turn, and after each change, the remains of the previous material should be completely removed from the nozzle to avoid color blending. In order to do this, a purge block, or prime tower, is printed to extrude the remaining filament — not the best way to save on material, though.

An interesting example of such a system, although it is not a printer itself, is the Mosaic Palette 3 Pro filament splicer, allowing for continuous printing with up to 8 filaments. The device is compatible with most single-extrusion FDM printers, and allows converting them to multi-color machines. The Palette 3 Pro also helps to save on purge blocks, as they can be included in the printed model as the infill parts.

Another example of a single nozzle dual-extrusion system is the Creality CR-X Dual Color 3D printer with a large build volume and vast creative opportunities.

Dual nozzle. This type of dependent dual extrusion uses a single print head with two dependent nozzles. This type of dual extrusion is faster than that using a single nozzle setup, as you do not spend time on switching filaments. It also gives you more freedom, as you can print with different filament types, using various nozzle diameters. Printing water-soluble support structures is a great advantage of this system.

On the downside, there is a risk of oozing, which can be minimized by creating an ooze shield — a one-layer wide wall created around the printed part to catch the remaining filament on the nozzle. Another way to avoid oozing, already mentioned above, is to build a prime tower, that is a block next to the part being printed.

Independent dual extruder system

The Independent Dual Extruder system, called IDEX, is the most advanced dual extrusion technology, as it uses two print heads moving independently from each other on the X-axis (still being dependent on the Y / Z-axes). Featuring all the benefits of a dependent dual extrusion system, like multi-material or multi-color printing, IDEX provides a huge advantage, which is simultaneous printing of two copies of the same model, either in duplication or in mirror mode. The latter can be used, for example, for making two insoles for a pair of shoes in one go. This ability means that you can double the production speed, which sounds great for batch manufacturing.

As nothing is perfect, IDEX also has its drawbacks. Firstly, the second print head adds considerable weight, thus introducing the risk of Z-wobbling. Another thing with using IDEX printers is the reduced build volume when printing in single or dual extrusion modes; while duplication mode uses the entire effective build plate area. The example of this is the CraftBot Flow IDEX XL dual extrusion 3D printer. It features the total build area of 425 x 250 x 500 mm, which is reduced to 386 x 250 x 500 mm in single print head mode, and to 351 x 250 x 500 mm in dual print head mode; while duplication mode uses the whole 425 x 250 x 500 mm build area.

Dual extruder printers — buyer’s guide. Answers to FAQ

What is a dual extruder 3D printer?

A dual extruder 3D printer, as the name suggests, is equipped with two extruders, which allows the user to combine two (or sometimes more) filaments in one project. There are different types of a dual extrusion system, with the IDEX being the most powerful. Besides multi-color and multi-material printing, as well as printing soluble support structures, it features duplication and mirror modes, which can double the production volume.

Can the Ender-3 do dual extrusion?

The Creality Ender-3 is a very popular model of an affordable consumer FDM 3D printer. It is equipped with a single extruder, but there are some options allowing the user to upgrade it to the dual extrusion system. The most obvious and safe way to do it is to buy a filament splicer, or changer, that can work with most FDM 3D printers (more of that below).

Another option is to upgrade your printer with one of the DIY open-source solutions, but they usually require serious modifications that are often irreversible. So, be sure that you really need it. The most popular modifications are DIY Chimera Project, Cyclops Hot End, and some others.

 

Can dual extruder printers print with soluble filaments?

Yes, they can. Dual extruder printers can use one nozzle for printing the part with the main material (PLA, for example) and the other for PVA water-soluble supports. For ABS parts, HIPS (which dissolves in limonene) is often used for building support structures.

Does dual extruder print faster?

When two nozzles are used instead of one, the overall printing time shortens significantly. Moreover, with the IDEX printers, you can double the productivity of your device using duplication and mirror modes.

 

How many extruders can a 3D printer have?

Normally, FDM 3D printers are equipped with a single or dual extrusion system. There are a few printer models in the market featuring triple extrusion, but they are not so popular, as the dual extrusion system is complicated enough and requires more maintenance, not to mention the triple one. There are also various third-party mods allowing for three or even four-nozzle setup.

 

Do dual extruder printers have an enclosed build area?

The situation is pretty much the same as with single extrusion models. Most entry-level consumer devices feature an open design, which sometimes can be complemented with an optional enclosure. More expensive professional-grade printers are usually fully-enclosed. The enclosure is absolutely necessary if you plan on printing with high-performance materials.

 

Can you 3D print multiple objects at once?

With IDEX printers you can print two copies of the same model either in duplication or in mirror mode.

 

What is the average price of a dual extruder 3D printer?

With the development of 3D printing, a lot of technologies that were only used in professional printers have now become affordable for consumers. Today you can buy an entry-level dual extrusion 3D printer for less than $500.

 

How do you print multiple filaments?

In dual extrusion printers, you don't have to manually change filaments to print with different materials, as they are equipped with two extruders, and the switch between them happens automatically. Dependent dual-extrusion systems only allow printing with two filaments in turn, while IDEX printers can use both nozzles simultaneously, increasing the print speed.

How to make a dual extruder 3D printer?

If you already have a single extruder FDM 3D printer, you do not necessarily have to buy a dual extrusion device to give a try to multi-material printing. You can upgrade your printer with a filament splicer, like the Mosaic Palette 3 Pro, mentioned above.

Another affordable option is the 3D Chameleon automatic color changer, allowing for the use of up to four filaments in one model.

One more way to make your printer work with different filaments (up to 12!) is the SMuFF V6 — an open-source DIY smart multi-filament feeder. It may not be the choice for beginners, as it requires certain skills in configuring your printer’s firmware, but if you feel confident with that, it is definitely an option.

How to choose a 3D printer for printing with 2 materials?

Good afternoon everyone!

In this article, we would like to talk about the issue that torments many customers when choosing a 3D printer with 2 extruders. Namely, which is better? What is more stable? Which 3D printer to choose? Why do dual extruder 3D printers alone cost significantly less, and what is the difference between them?

First of all, let's start with the fact that by printing with 2 extruders (or 2-component printing), we mean the ability to print with 2 materials, for example, PLA (base material) and PVA (temporary support material removed chemically, using water in this case ). nine0003

It is possible to print in two different colors. But in practice this has not received any great distribution. Printing of complex models with dissolvable supports is in demand.

Therefore, you need to decide for yourself why you need a 3D printer with two extruders? For most tasks, it is enough to use a 3D printer with 1 extruder.

The use of a dual extruder 3D printer is a must when printing complex 3D models with dissolvable supports. Usually such 3D printers are chosen by manufacturing companies for printing geometrically complex prototypes or owners of 3D printers with 1 extruder who understand that they cannot realize with a 3D printer with 1 extruder. nine0003

But do all 3D printers with 2 extruders have the same capabilities? Or is it that the differences in design, and, accordingly, in price, are of decisive importance?

Let's consider various solutions for 3D printing with 2 materials on the 3D equipment market.

To implement this function, manufacturers use the following solutions:

Decision No. 1

Use of 2 static extruders. As a rule, these are 2 hot-ends with two independent material feed motors. There are many options. But all of them, to one degree or another, repeat the solutions on the Makerbot Replicator 2, released in 2012. nine0003

There are several technical solutions, but they all have a common list of disadvantages and features.

Weaknesses :

1) Be sure to align both nozzles horizontally with respect to the desktop of the 3D printer. In other words, the nozzles of each hotend should be at the same height, ideally with an error of no more than 0.1 mm.

2) Using a utility tower (or analogues) to clean the inactive nozzle from plastic drips (drop formation) before switching to the active mode for printing. Let's consider an example: if nozzle No. 1 prints a model with blue plastic, then in order for nozzle No. 2 to start printing white, the printer must first print the 1st layer of the tower with nozzle No. 2 to remove plastic residue, and only then move it to print the base model ( see picture). And so every switch. This greatly (at times) slows down the print speed, relative to the same model but when printing in 1 color. Moreover, there is a possibility of the collapse of the utilitarian tower (the layer did not fit well, or peeled off from the desktop) and, as a result, the marriage of the entire project. nine0003


3) There is no guaranteed result. Due to the complexity and imperfection of the extruder architecture. Large marriage rate. A nozzle that is currently inactive can leak plastic and ruin the part.

Advantages:

1) Low cost solution

2) Simplicity of design, as a result - high maintainability.

This option has the lowest price and the lowest overall performance. The complexity of the settings, to obtain a high-quality result, makes this implementation option a testing ground for experiments at home. In a more or less intensive implementation of projects, this option is quite problematic. nine0003

Solution #2

Using a Diamond type extruder. These types of extruders use a single feed motor and a radiator(s) (or cooling module) with multiple internal plastic passages.


Basically, such an extruder is used to print different colors. But this, as we already know, has not received much distribution in reality. Printing with solvent material will be somewhat difficult. Firstly, the base material and support material have different operating temperatures. This will cause some difficulties for quality printing. nine0003

And in any case, this design has almost the entire list of disadvantages, like the first option.

Only there is no point about the alignment of the nozzles - here it is one.

Weaknesses :

1) There remains the need to use a utility tower (or analogues) to clean the nozzle from plastic streaks (drop formation) before switching to another material. This "tower" is visible in the photo. This greatly (at times) slows down the print speed, relative to the same model, but when printing in 1 color. Here it will still probably take time to change the temperature of the nozzle, when changing the base material to supports. Or the possibility of poor-quality printing will greatly increase. nine0003

2) There is no guaranteed result. Due to the complexity and imperfection of the extruder architecture. Large marriage rate.

3) This type of extruder is equipped with Bowden-scheme plastic feeding. This entails difficulties (more often, even the impossibility of printing with flexible plastics)

The benefits are gone too.

Such a solution is quite expensive. And it has a complex structure.

Advantages:

1) Better print quality than option #1. nine0003

As a result, in the option of printing with two materials with dissolvable supports, there are no special advantages over the first solution. But this option has a higher price.

Resolution #3

Extruder designs where the currently inactive nozzle rises to avoid problems. Today's most famous commercial printer is the JetSwitch™ circuit.

Rotary nozzle system from PICASO 3D. nine0003

There is one plastic feed motor, which facilitates the design.


The main feature is that with the help of a rotary mechanism, one of the nozzles, which is active at the moment, is lowered to the working level. The second is closed at this time, and no molten plastic flows out of it.

Advantages:

1) High quality printing

2) There is no need to build a utilitarian "tower". Therefore, the switching time between extruders is short. Printing speed with two materials is MUCH faster than options 1.2. Below is a comparison table from PICASO 3D. nine0003


Weaknesses :

1) Relatively complex design, and as a result - a high price.

There are several more options for extruders with lifting nozzles. All of them are united by one thing - a much higher print quality with two materials than the "classic" option No. 1. Yes, they all have a higher price, but the print quality is drastically different.

The conclusions are as follows - by purchasing an inexpensive design, you save money, but spend many times more time on setup and printing itself. With the remaining risk of marriage, which reduces all efforts to zero. At the same time, the print result will still be worse than that of designs with lifting nozzles. nine0003

If you need a high-quality result and the printing time of complex models is critical, then it makes sense to choose a model with lifting nozzles:
