So you’ve done everything you can think of when it comes to 3D printing projects, and you’re looking for a new challenge. Now is the perfect opportunity to try dual extrusion printing!
In simple terms, dual extrusion follows the same principle as regular FDM printing. The difference lies in the printer’s ability to automatically switch between filaments at designated times, combining colors or even materials, and therefore achieving prints that couldn’t be done with plain old single extrusion. If you’d like to learn more, check out our article all about dual extrusion 3D printing.
This time around, we’ll share our favorite models that really make use of your printer’s dual-extrusion capabilities. With them, you’ll be showing off what it can do, and you’ll be recreating designs that you wouldn’t be able to print otherwise.
If you love one of these models but don’t have a dual extrusion printer (yet!), try Craftcloud by All3DP. With a range of materials and finishes, your perfect two-toned model will show up at your doorstep after just a few clicks.
But before we jump into our picks, let’s check out some dual extrusion printers.
Printer Options
There are many dual extruder 3D printers currently on the market.
For example, the Flashforge Creator Pro 2 and Snapmaker Artisan are great options, even if they do have a slightly high price (depending on your budget), and while Geeetech’s A10M may be a few years old, its accessible price makes it worthy of consideration.
Of course, there are more options, and with a printer like one of these, you’ll want to use it for all its worth. So let’s go double-time to the list!
Animals
Animals can be some of the most complex prints in regard to textures, colors, and finishes, so they’re the perfect challenge for your machine. Everyone can appreciate a 3D print of an animal that looks just like the real thing.
Salamander
In the city of Barcelona, there’s a magical park called Parc Güell, which was designed by the architect Antoni Gaudí. The entrance to the park has a beautiful salamander that was the inspiration for BCN3D Technologies’ mascot, the Draudi.
There are many Draudi versions, but the Dual Draudi is specifically supposed to help you test the capabilities of your printer and its settings. Several makers have had success printing in PLA and ABS, setting infill percentages at 10-20%, and with and without supports activated.

Tree Frogs
For tree frogs, we’ve found two designs that are both inspired by real frogs. The first one was discovered in 2013 and is called the tiger’s tree frog. It’s a rare species that has an incredible maze-like pattern on its skin and lives in the rainforests of Colombia.
The second is called the red-eyed tree frog, which, in addition to its red eyes, has orange feet, a green body, and blue legs. You can find it in different regions of Central America or in your house when you’ve 3D printed it!
Tiger’s
- Who designed it? nervoussystem

Gizo the Spider
Spiders don’t have to be scary, as you can see by this model. They can also be cute and fluffy. They’re also pretty popular: This model has a whooping 145 makes shared so far, and the model was added to more than 2,300 collections. Even though it’s a dual printing model, it isn’t an overly complicated print, and the designers have also shared files to print the eyes separately in case you don’t have a dual extruder machine.
Users who’ve made it recommend using a raft for the legs, which are print-in-place with the rest of the body. The eyes are where the dual color print comes into play.

Lizard
Have an empty tank and looking for a very low-maintenance pet? Then this realistic dual-colored iguana-styled lizard is for you!
A user mentioned issues with the scaling of the eyes, so you may need to reduce them to 25% or even less to fit with your model. One successful maker scaled the lizard and branch to 110% and used 0.15-mm resolution, 10% infill, and supports to accommodate the branch overhang.

Stegosaurus
Everyone loves dinosaurs, so why not make them as 3D printed models? Just be sure to never replicate their DNA and create modern-day real-life dinosaurs, since we’ve seen how that movie ends… six times.
The model was separated and split into two STL files for dual extrusion from a design by Werd119. It should take you about 20 hours of print time with a 0.2-mm layer height, 20% infill, and a print speed of 70 mm/sec.
- Who designed it? Adafruit

Sci-Fi & Fantasy
Sci-fi and fantasy prints are some of the most fun, original, and complex ones out there. Not to mention it gives you the opportunity to try really difficult geometries! As such, dual extrusion sci-fi sculptures offer a combination of stunning color and creative designs.
Alien Heads
This design by BCN3D was originally made for single-extruder printers, however, seeing how amazingly expressive this creature was, they decided to add a touch of color to make it even more exciting.
It’s designed to be printed without supports. In order to achieve the best surface quality, a layer height of 0.1 mm is recommended.
- Who designed it? BCN3D

3D Phil
Phil A. Ment (get it?), also known as 3D Phil, is the mascot astronaut for the company MatterHackers. Also originally made for singular extrusion, this dual extrusion version was released as dual extrusion printers gained more popularity.
It was designed with troubleshooting in mind and has several features that purposely put your printer through the wringer. It also has versions for resin and even laser cutting.
Most of the makers who printed this used infill percentages from 10% to 35%, and they all came out great.
- Who designed it? MatterHackers
- How printable/popular is it? Dr. Phil A. Ment has 20 makes for the dual version and over 13,600 downloads.

Unicorn
This piece looks simple enough, but when printing something that has “hair”, you’ll have to be a little careful. You won’t need supports, but you should increase bridging speed by at least 150% as well as the print cooling (print fan speed) settings. Right out of the printer, the hair will be spiky. So, dip the hair in a bowl of very hot water for a few seconds, then shape it.
According to the designer, if you’re printing this at 0.3-mm layer height, the hair will be fairly brittle. If you print it at 0.2-mm, there’ll be two passes on each strand of hair so that they’re less likely to break when you mold them.
- Who designed it? Geoffro
- How printable/popular is it? This model has an impressive 118 makes, though most aren’t using dual extrusion.

Robot
The robot mascot from UltiMaker is stuck in frozen water in this nifty design. Inspired by GoT’s famous saying “winter is coming”, this particular model makes use of both solid color and transparent filaments to achieve the desired effect. However, you can use whatever colors you prefer, like green for the ice blocks, transforming them into blocks of emerald!
Rupee the Articulated Dragon
This colorful and creative articulated dragon is a great addition to your dual extrusion collection. It makes a great decoration for fantasy-themed collections and displays. Increase the visual appeal by using bright, contrasting colors or opting for silk PLA filaments!
With the dense circular orientation of the model, try a wall in place of a wiping tower. If you still experience some color spills, try increasing your retraction or travel speeds, or lowering the print temperature.
- Who designed it? AlexisTheEel
- How printable/popular is it? This model has been downloaded around 300 times so far – a number we’re betting will only increase!

Rocket
Like most engines, rockets burn fuel, turning it into hot gas. The engine pushes the gas out the bottom, making the rocket move forward. Neat, right?
This rocket can’t actually fly, but it’s an amazing and challenging dual print. It’s a pretty large project for dual extrusion, so make sure your printer has the necessary dimensions.
- Who designed it? Geoffro
- How printable/popular is it? This impressive rocket has 4 makes and about 2,600 downloads on Thingiverse.

Movies & Games
For those of you who are part of a kingdom of fans (did you know that’s where the word fandom comes from?), we’ve gathered a great selection of dual prints related to movies and video games.
Pikachu
Pikachu is by far the most popular and well-known Pokémon. If you’re more of a fan of other Pokémon, the creator of this Pikachu has also made versions for Bulbasaur, Squirtle, Charmander, and more.
You can choose two ways of printing this model: The first, for dual extrusion, is divided into two different parts. The second divides the model into three or more parts, which is perfect for multi-extrusion 3D printers or color-mixing techniques.
- Who designed it? flowalistik
- How printable/popular is it? This model has around 40 makes and 2 remixes, including a few multicolor, prints. There are many versions of it printed all across the internet.

Hulk
For anyone who’s a Marvel Cinematic Universe fan, or who wants to get a jump on printing the rumored Red Hulk that might appear in Captain America: New World Order, this model is for you! This remixed version of the Incredible Hulk allows your dual extruder setup to give Mr. Banner’s alter ego skin of one color and pants and hair of another.
This model has been successfully printed in several ways with 0.2-mm resolution and 20% infill. You can choose to print the model standing on its feet, where tree supports are recommended to ensure the arms and head come out intact. For a cleaner look, you can print the model lying on its back, with any support style and top layer ironing, just be sure to figure out the retraction settings for your second extruder. A base raft may not be necessary, but a skirt and a wiping tower are always a good idea if you’re hoping to nail this print on the first try.

Containers
Printing gadgets for your home in the comfort of your home is always convenient. This small selection of gadgets will occupy your time, challenge your dual extruder, and look cool when they’re done.
Twisted Bottle & Screw Cap
If you’re looking for a colorful case with a lid, this twisted bottle with a screw-on cap is a perfect project for your dual extruder.
In the time-lapse video, the creator uses a skirt and a wiping tower when printing. The gradual curvature should not require supports, but a temperature test might be a good idea for scaled-up prints. Feel free to scale it to your needs!
While it has a price tag (~$1), the unique design more than justifies it!
- Who designed it? David_Mussaffi

Pumpkin Coin Box
When it’s time to save some money for new filament, but you don’t have a coin box, this is your solution.
It’s recommended to print the parts with a 20% infill and 0.15-mm layer height. There are also two parts that need supports. You’ll require some additional components to complete the assembly, including brass rods. The creator includes a video and detailed explanation of how to put this pumpkin together on the project page.

Pen Holder
This completely safe pen holder is perfect for fans of dystopian sci-fi. Now, you can keep your desk de-cluttered and make people think twice about borrowing a pen!
The model files include compatibility with both regular and dual extruder printers. Be forewarned: The single-color version requires some precise gluing after all of the printing is done.
Psychedelic Vase
If you’re looking for ways to personalize your home, try this cool vase. You can print it in either one or two colors, but it’s much more striking when fabricated in contrasting shades.
The original print was made with ABS, but PLA should be fine too. If you’re putting water in it, make sure you’re creating a watertight container.
Toys
Because we all love to play, this final category has a variety of great toys to 3D print. Not only will you be testing your dual printer, but you’ll also get to play with the results.
Tensegrity Arc
Who said science isn’t fun? This interesting print is based on the Tensegrity concept proposed by Buckminster Fuller and explored in this model by alecsform. This is a great example of a model where dual printing is fundamental, as creating the parts separately and gluing them together wouldn’t have the desired effect.
The model is held together by thin strings that are tensioned and are constantly pulling on each other and the other elements to keep the model in place. It doesn’t need supports because it uses bridging.

D20
D20 dice are a feat of mathematics and an icon of geek culture. Even though it has a complex geometry to design, whether by hand or with the help of CAD, it’s actually an easy print.
The designers say that you can scale the die up and add electronics if you’d like!

Traffic Cones
To keep traffic in order, we’ve found these great traffic cones that come in several designs. They were created using a parametric system for different patterns with auto subtraction operations.
These cones can be scaled to any size, but for big prints, modifying the file to make the wall thinner (you’d just need to change the variable “WALL”) is advised.
If you keep the size as is, the layer height should be 0.2 mm or smaller to make sure the details don’t get lost.
- Who designed it? R3nd3r
- How printable/popular is it? These traffic cones have 21 makes and 1 remix.

Wind-Up Car
What’s better than 3D printing? 3D printing things that move! This wind-up car works with a spring and a trinket, both of which are 3D printed.
To compensate for the considerable weight of the car, the designer upped the final drive gear ratio to 1/16 and strengthened the axles and gears to handle the increased torque. After testing, the vehicle apparently can easily travel around 40 feet over smooth surfaces. Detailed assembly instructions are included on the project page.
- Who designed it? Greg Zumwalt

Fire Truck
This colorful fire truck is a great toy for those little ones aspiring to be a first responder. Despite its print-in-place style, it has moving parts and a deployable ladder, which also makes it a great action toy.
This model has been successfully printed with resolutions from 0.1 to 0.2 mm and a 15% infill. No supports or rafts should be necessary if you combine the two files together carefully and print them on their side with the extending ladder pointing up. This also ensures that the wheel axles will move freely. If you’re having issues with clearance, a maker recommends adjusting the horizontal expansion to -0.05 mm in the slicer settings.
- Who designed it? ucdmoo
- How printable/popular is it? While it looks innocent this may be a more difficult print, and it might take a few attempts to get all of the parts moving. That said, at least two successful makes have been shared, and two more makers have confirmed in the comments their prints, so you should be able to create one too!
- Where to find it? Thingiverse
Colorful Wind Wheel
There’s a lot going on here. This print is available in two different versions: one with the big wheel and another with just the flower. Beyond that, there are a lot of color combinations, textures, transparencies, and resolutions you can play with to make this model your own unique version. On the other hand, it doesn’t need supports, which simplifies a lot of the printing process.
The creator gives very detailed instructions with pictures for the hard parts, and the printed design looks stunning. In order to increase resolution in certain, more demanding areas, you might benefit from a slicer program with multi-processes.
- Who designed it? mageb

Micro Glider
To add a different note, instead of models that are focused solely on color, this print mixes materials. This lightweight micro glider can actually fly!
The wings are made of a thin layer of FilaFlex (0.2 mm) and the body of PLA, creating an elastic membrane. Let this model inspire you with the possibilities of creating lightweight flying gadgets.
Even though the concept is different, it should be a pretty easy print since it’s small, thin, and doesn’t require supports. However, a Bowden extruder is recommended.
Clockwork Heart
Designed as a gift for someone special, this heart moves when you turn the gears by hand. It can’t be assembled; pieces are printed inside other pieces.
The creator warns that tolerances are tight, so be careful of over-extrusion and elephant’s foot. It might also be a good idea to do some calibration on your printer before you try this model. You’ll need some dowel pins for assembly. If you need extra help, a fellow maker posted a video detailing how to put this heart together.
