3D Printing has come a long way from its early days of basic single-material prints. With the introduction of dual extruder 3D printers, it has opened doors to new possibilities, improving efficiency, design complexity, and material diversity. If you’re considering adding one to your setup, here’s what you need to know.
What Is a Dual Extruder 3D Printer?
Imagine having the ability to print with two different filaments at the same time. That’s exactly what a dual extender 3D printer brings to the table. With two separate extruders, you’re no longer limited to just one material or color. Instead, we can explore multi-material printing, create stunning dual-color designs, or even use soluble support materials for complex, intricate geometries we’ve always wanted to try.
But this isn’t just an upgrade from a single extruder. It’s a whole new level of creative freedom. If you’re designing functional prototypes or pushing the boundaries of artistic projects, a dual extruder printer gives you the tools to turn ideas into reality.
Types of Dual Extruder Printers
Not all dual extruder 3D printers are built the same, and that’s a good thing. It means there’s likely one out there that fits your unique needs perfectly. Let’s break it down so you can make an informed decision that suits your unique needs.
Independent Dual Extruder (IDEX)
If you’re someone who values precision, efficiency, and the ability to take on complex projects, an IDEX system might be your perfect match. They’re a dream for anyone managing high-volume production, with features like duplication mode, where you can print two identical parts at the same time, effectively doubling your output.
On the other hand, there’s also a mirror mode, where the printer creates mirrored parts simultaneously. These printers are all about efficiency and flexibility, making them a reliable partner that keeps up with your creative demands.
However, IDEX systems tend to come with a higher price tag and a larger footprint, which might not be ideal for those with limited space or tighter budgets. Still, if you’re looking to maximize productivity and handle intricate projects, the investment in an IDEX printer could be well worth it.
Fixed Dual Extruder
Now, if you’re like us and sometimes just want a straightforward, dependable machine, fixed dual extruders are a fantastic option. These printers have both extruders mounted on the same print head, so while they don’t offer the independent movement of an IDEX system, they still let us experiment with two materials or colors in a single print. That’s perfect for projects like multicolor designs or models that require a combination of materials, such as rigid structures with flexible components.
One thing we appreciate about fixed dual extruders is their simplicity. They’re usually more compact and affordable, making them a great choice if you’re working with a tighter budget or limited space.
On the flip side, the lack of independent extruder movement does mean these printers aren’t as efficient for high-volume or complex jobs. Switching between materials is slower compared to IDEX systems, and you may run into limitations if you’re working on intricate designs.
Swappable Tool Head
If versatility is what you’re after, swappable tool head printers might be your ideal match. These machines give you the option to switch our tool heads based on the task. For example, we’ve used printers with swappable heads to shift between standard printing, high-precision work, or even specialty filaments that require different nozzles. This allows us to adapt our printer to fit specific project requirements, which has been helpful when working on diverse designs.
The good thing here is that you’re not locked into a permanent dual extruder setup. If you’re someone who doesn’t always need dual extrusion but wants the option for occasional use, a swappable tool head system strikes the perfect balance.
Of course, this setup isn’t without its cons. Changing tool heads may interrupt your workflow, and there’s a bit of a learning curve to make sure that everything is properly calibrated after each swap. However, for us, the ability to switch functionalities without investing in multiple machines has been a significant cost and space saver.
Why Should You Get a Dual Extruder 3D Printer?
The possibilities that open up with dual extrusion are incredible, and once you start using one, it’s hard to go back. We can tell you from experience. It absolutely is worth the investment, especially if you’re looking to expand what you create.
Combine Multiple Materials for Functional Parts
One of the biggest advantages of a dual extruder printer is the ability to combine different materials in a single print. For us, this has been a game-changer. Imagine being able to pair a rigid material like PLA with a flexible TPU to create functional prototypes or end-use parts. Or using water-soluble support materials such as PVA for intricate designs that have overhangs and internal cavities that would be impossible with a single extruder. This ability to mix and match materials has completely transformed how we approach complex projects.
Create Stunning Multicolor Designs
The aesthetic factor is definitely one of the reasons why you should get such a printer. They make it so much easier to create stunning, multicolor designs. We’ve used this to add vibrant detail to models without spending hours painting or assembling parts after the fact. It’s more than just convenience. It’s about taking the quality of your prints to the next level. Whether it’s for professional presentations, prototypes, or even artistic pieces, the results speak for themselves.
Boost Your Efficiency
One of the things we love most about dual extruder printers, especially IDEX systems, is their ability to print multiple parts at once. We’ve saved countless hours by printing two identical parts simultaneously or creating mirrored components in one go. Now, if you’re handling high-volume jobs, this kind of efficiency is something you need.
Reduce Material Waste
Now, here’s something we’ve come to appreciate more and more: less material waste. Dual extruder printers often include features like purge blocks or wipe towers to manage material switching silently. While it’s not completely waste-free, it’s far better than manually swapping filaments mid-print, which can be frustrating and lead to wasted materials if something goes wrong.
Expand Your Creative Freedom
Of course, we’ll never miss mentioning the sheer creative freedom these machines can offer. Once you start experimenting with dual extrusion, you’ll realize there’s so much more you can do. This has redefined how we think about 3D printing, from mixing materials to exploring multicolor designs and complex geometries. The only limit is your imagination, and maybe your filament supply!

If you’re working on intricate prototypes or large-scale models, this printer gives you room for bigger execution.
What sets Ultimaker S5 apart is its ability to handle multiple materials with ease. Pairing standard PLA with water-soluble PVA has been a revelation in our workflow with this machine. If you’ve ever spent what feels like hours carefully removing supports from a delicate print, you’ll appreciate how this machine simplifies everything. We’ve used it to create intricate parts that would have been nearly impossible with a single extruder. The support material can be easily removed, leaving us with clean, polished prints.
Another highlight is its slicing software, Ultimaker Cura. Let’s be honest, not all slicing software is easy to navigate. But Cura strikes that perfect balance between powerful features and user-friendliness. Whether you’re new to dual extrusion or a seasoned expert, you’ll find it intuitive and packed with options to fine-tune your prints. For us, Cura has become as essential as the printer itself.
Now, let’s talk about challenges. The Ultimaker S5 isn’t cheap. It’s an investment, plain and simple. If you’re just dabbling into dual extrusion or 3D printing in general, this might feel like too big a leap. It’s also not the fastest printer out there. While the print quality is consistently excellent, we’ve had moments when we wished it could move just a little quicker, especially during large, detailed projects. And like any high-end machine, it requires maintenance. We’ve had to stay on top of cleaning and calibrating to keep it performing at its best.

Raise3D Pro3 has the 3D printing community raving, and we knew it was something special.
One of the things we love about this machine is its incredibly well-designed dual extrusion system and the hot-swappable print heads making it versatile enough to handle a wide range of materials. We’ve used this feature to alternate between standard and abrasive filaments without needing a second machine, which has saved us time and money.
Another thing is its large build volume. Whether we’re printing detailed architectural models or functional prototypes, the Pro3 has the space and precision to get the job done. Additionally, automated features like bed leveling and flexible build plates have also made 3D printing much easier, especially for those that run overnight or require a lot of setup.
And when they talk about user-friendly features, they are certainly right. The touchscreen interface is intuitive, and RaiseCloud’s remote monitoring has been a lifesaver during busy weeks when we couldn’t be near the printer all the time. It’s been incredibly reassuring to check on prints from our phones and make adjustments as needed.
However, as much as we love the Raise3D Pro3, there are some things to consider. For one, it’s definitely on the pricier side, so it’s more of an investment for those serious about 3D printing. But then, the cost is justified by the consistent quality and reliability.
And also, there’s the machine’s size and weight. It can be a challenge as it’s not the kind of printer you casually move around, so you’ll need a dedicated space for it.
Bambu Lab A1 Mini + AMS Lite
The Pros | The Cons |
|
|
When we first set up the Bambu Lab A1 Mini and paired it with the AMS Lite, we couldn’t wait to see how it would perform. It’s marketed as a small but capable printer for multicolor enthusiasts, so we were eager to test its limits.
One of the first things that stood out was the compact design. If you’re tight on space, this printer is a lifesaver. Setting it up was straightforward, and the user-friendly interface had us ready to print in no time.
The price point is another win. If you’re looking to get into multicolor printing without breaking the bank, the A1 Mini + AMS Lite is a great option. We’ve tried higher-end printers with similar capabilities, and while they’re fantastic, they’re not always budget-friendly.
Moreover, we were pleasantly surprised by how quiet it is. Printing can often be a noisy process, and let’s face it, not everyone has a dedicated workshop where they can shut the door and tune out the sound. The A1 Mini is one of the quieter machines we’ve used.
Now, as good as it may be, there are things to consider. The build volume is on the smaller side, which means we had to scale down some of our designs or split them into parts. If you’re working on big, ambitious projects, you might find this a bit restrictive.
Another thing we noticed is that multicolor prints take a little longer. The AMS Lite system is a great addition for switching between up to four filaments, but the process slows things down compared to single-material prints. However, It’s not a dealbreaker. It’s just something to keep in mind if you’re on a tight schedule.
How to Choose the Best Dual Extruder 3D Printer
Choosing the best dual extruder 3D printer can feel like a big decision, especially with so many options out there. We’ve been through this process ourselves and learned a few things along the way that can help narrow down your choices.
First, think about what you want to create. Are you focused on intricate designs with multiple materials or colors, or do you need something more straightforward? The type of projects you plan will heavily influence your decision. For example, if you’re working on detailed prototypes, a machine with precise alignment and material versatility is the key. On the other hand, if efficiency is your priority, look for IDEX systems that allow for faster production.
Next, consider your workspace and budget. Dual extruder printers come in a wide range of sizes and price points, so if your space is tight, compact models like Bambu Lab A1 Mini could be a better fit. If your budget allows for a larger machine, you might consider getting the Ultimaker S5, as it offers more flexibility.
