What is a Dual Extruder 3D Printer?
A dual extruder 3D printer is a machine that has two extruders, as the name suggests.
These extruders can be used to print with different colors or different materials simultaneously. This way, you don’t have to swap out filaments every time you want to change the color of your print.
You can also use dual extruders to print with multiple materials at the same time, for example, printing with both ABS and TPU filaments in a single 3D print. This opens up a lot of possibilities for interesting prints that wouldn’t be possible with a single extruder printer.
In this article, we’ve covered three types of different dual extrusion 3D printers: Single hot end setup, Dual hot end extrusion, and Independent Dual Extruder system (IDEX).
The single hot end setup is the least complex. It gives you the benefits of dual extrusion 3D printers without actually having a second print head or a complex motion system.
The dual hot end setup incorporates a second print head next to your primary hot end, and both hot ends move together.
You can assign different materials for each hot end, effectively giving you the capabilities of printing with two 3D printers, albeit on a single print bed.
One of the best and the most practical applications of dual extruders is the IDEX style of 3D printer. These printers have two independent print heads that can be controlled and moved separately. This gives you a lot of control over the printing process and opens up a lot of possibilities for complex prints.
What is the Benefit of a Dual Extruder 3D Printer?
A dual extruder 3D printer triumphs over the regular single extruder 3D printer in many ways. You do not need to swap out any filaments mid-print for any color changes, leading to a faster print speed.
You can print with multiple materials simultaneously with a dual extruder printer. You can use one print head to print the outer shell of the model, while the secondary hot end will print the infill with a more robust material. Similarly, you can use filaments with different colors to print a colorful model.
IDEX printers give you the added benefits of printing modes. You can print multiple objects simultaneously with the duplication mode and print a mirrored version of your design with the mirror print mode. It leads to increased productivity and is useful for 3D printing larger batches of objects.
The last and probably one of the most popular benefits of dual extruder 3D printers is their ability to print soluble supports. You can use PVA or HIPS filament in your secondary extruder to print water dissolvable supports. It gives you the freedom to print complex objects and significantly saves post-processing time, as it takes away the need to remove supports manually.

What to Look For When Buying a Dual Extruder 3D Printer
Dual extruder type
When you consider buying a dual extruder 3D printer, you’ll come across technologies such as the IDEX system, double hot ends, and a single Y-shaped hot end.
The IDEX system lets you simultaneously 3D print with two independently driven extruders and a hot end setup.The advantages of an IDEX system are the multiple printing modes that you get with it. You get to duplicate and mirror your models, effectively resulting in increased productivity.
If you look at the single hot end setup, you’ll notice that the hot end is much lighter, and you do not lose any printing area to a second print head. The downside, though, is that this setup is more likely to run into issues, as a single print head is used for multiple materials at a single time.
The most common and relatively more accessible dual extrusion system is double hot ends. You get two individual hot-ends and extruders, and each hot end can be configured to print a single material with maximum efficiency. However, two hot ends next to each other occupy extra space, cost more, and do not increase productivity like the IDEX system.
If you want a printer for maximum productivity and are looking to run it into print farms or to run multiple batches of prints, the best dual extruder 3D printer for you is an IDEX one.
In contrast, the dual hot end setup is more suitable for conventional dual extrusion 3D printing, where you do not need to print many parts.
Printing modes
While the single nozzle and the dual hot ends styles let you print with multiple materials and soluble supports, printing modes are truly available only on the IDEX style of dual extruder 3D printers.
There are four printing modes that come with dual extruder 3D printers – Mirror, duplication, soluble supports, and multi-material mode. The mirror mode lets you print symmetrical mirrored objects, and you can print the part and its inverse simultaneously. For example, shoes, gloves, and other things come in a couple but are symmetrically opposite.
Another helpful model is the duplication mode, which helps carry out batch prints. In duplication mode, both the hot ends repeat the same movements and produce identical copies of the original design. It drastically improves your productivity rates and is suitable for print farms.
The soluble supports and the multi-material modes are similar and not just available in the best dual extruder 3D printers; any dual extruder printer can do them. While the primary nozzle is used for the main filament, you can use the secondary nozzle with either soluble supports or a differently colored material.
Print Volume
The dual extruder design reduces the printing volume of any 3D printer due to the extra space the secondary extruder takes up. This results in a smaller printing volume on the Y-axis in dual extruder printers compared to a single extruder setup.
When you use print modes, too, you’ll realize that the print area is reduced considerably due to the second extruder’s size in mirror mode. Hence, in the case of dual extruder printing, it becomes more crucial to look at the actual printing volume that you’ll get.
If you need a bigger print size, you should look at the Raise3D Pro 3, Ultimaker S5, and the BCN3D Sigma D25. These printers come with a large print volume that gives you more freedom to take full advantage of their dual extrusion capabilities.
Print Speed
Even with the addition of a second hot end on the motion system, the printing speeds of dual extruder 3D printers are relatively unaffected. Powerful stepper motors and a rigid frame can compensate for the added weight of the hot end.
Almost all of the 3D printers in this list can comfortably print at around 60-100 mm/s of printing speeds, while travel speeds go up to 200 mm/s. These speeds give you a good balance between print quality and lead times.
If you consider the other benefits of dual extruder 3D printers, you’ll realize that the printing modes lead to a considerable increase in overall productivity. The ability to print with two print heads simultaneously easily triumphs the faster printing speeds of any other 3D printer.
Filament Compatibility
Ensuring that your 3D printer is compatible with many filaments is one of the primary things you need to consider while buying any 3D printer. More so with dual extruder 3D printers due to their second print head.
The second print head is helpful for printing soluble supports. If you’re getting a dual extruder printer specifically for printing with soluble filaments such as PVA and HIPS, you should check whether or not it is compatible with these materials.
Every printer in this list is equipped to print with these materials. And some of the dual extruder 3D printers like the Ultimaker S3, S5, Raise3D Pro 3 go beyond and let you swap your print heads for printing with specific materials, thus increasing their material compatibility.
Enclosure
A 3D printer enclosure plays a crucial role with dual extruder 3D printers. The isolated printing area on enclosed 3D printers lets you print with tricky materials such as ABS filament and keeps 3D printing fumes within the printer body itself.
Aside from the Sovol SV02 and the Tenlog TL-D3, all other dual extruder 3D printers come with at least a partially enclosed design. And with the Creator Pro 2, you get the benefits of both; you can choose to keep the printer open on the top while printing with PLA and fully enclose it when you want to print with ABS.
The Ultimaker S5 goes a step beyond its airflow management system, however, the QIDI Tech i-Fast is the only dual extruder 3D printer on the list with an actively heated build chamber. This ensures that you get the best print quality and that the printer is compatible with a wide variety of materials.
Warranty
Warranty is often an overlooked factor when buying dual extruder 3D printers. You need to carefully evaluate the warranty conditions and everything that is covered within it. Some manufacturers offer a warranty on specific components for a short while, while the best dual extruder 3D printers tend to get comprehensive coverage of any manufacturing defect in the printer.
In this list, all the dual extruder 3D printers have at least a 12 months warranty period that covers any manufacturing defect from the company’s end.

Geeetech A20M (Best Value) 3D Printer Type: FDM | Materials: ABS, PLA & PETG | Build Volume: 255 x 255 x 255 mm | Print Speed: 180 mm/s | Color Mixing (Y/N): Y | Extruder: Dual
Geeetech has a couple of different 3D printers on the market, and I found the A20M to be its best option for multi-color 3D printing.
Given that the field is still highly experimental, the A20M doesn’t cost much, which is an immediate bonus.
In fact…
… for any reliable dual-extruder, the A20M is still a great price. It’s also blessedly easy to set up, and the dual-extrusion 3D printing technology tends to work well.
But the real reason I loved this 3D printer was its ability to push the envelope on color mixing.
You really don’t see this very much in personal 3D printers, and it’s completely unheard of at this price point.
With the Geeetech, you can expect to print in two distinct colors (striping or the like) or even mix and/ or grade your colors, allowing for a full spectrum of shades and hues.
- Excellent price point
- Great color-mixing technology
- Solid customer service
- Persistent clogging issues
- Poor plate cover

2. LOTMAXX Shark V3 (Premium Choice)
3D Printer Type: FDM | Materials: PLA, PLA+, ABS, TPU & Wood | Build Volume: 235 x 235 x 265 mm |Print Speed: 45-90 mm/s | Color Mixing (Y/N): Y | Extruder: Dual
The upgraded version of the LotMaxx Shark V2 brings new features to the table — and they’re good!
It has improved laser engraving capabilities — yielding finely-detailed engravings — and an overall sturdier frame and design with improved cable management.
It’s also much quieter than its predecessor, which will save you some hearing damage as a long-suffering 3D printer user. (Oh those stepper motors…)
The V3 comes with smart G-sensor auto-leveling — the G stands for gravity. This helps you get accurate and super precise leveling that will stay in place for a long time. Nice!
It also has a Resume Print function in case of electricity outages or other interruptions, as well as a filament detection sensor to alert you when the filament has run out.
This printer is compatible with PLA, PLA+, and ABS filaments. For laser engraving, it’s compatible with bamboo, leather, wood, ceramic tile, and craft paper.
It has a build volume of 235 x 235 x 265 mm and is equipped with ultra silent TMC2208 stepper drivers.
This printer comes with dual-color switching extruders and yields beautifully-colored prints. We loved our test prints — they came out very clean and the colors were perfect.
This printer can be used with the default LotMaxx slicer, as well as Cura and Simplify3D.
It supports microSD and USB connection
- High-quality dual-color printing and laser engraving
- Silent printing
- Filament detection sensor

3. Tenlog TL-D3 Pro (Best Choice)
3D Printer Type: FDM | Materials: TPU, PVA, PLA, ABS, HIPS, WOOD, PETG & Flexible | Build Volume: 300 x 300 x 350 mm | Print Speed: 10-150 mm/s | Color Mixing (Y/N): Y | Extruder: Dual
Unlike the printers before, the Tenlog TL-D3 Pro’s has two extruders and two nozzles.
It means that you can print two identical items simultaneously, in two distinct colors. You can also print in mirror mode and print in two different materials.
It seems like a pretty simple adaptation of the popular (and increasingly affordable) dual-extruder design.
Without delving too far into the enormous potential of this function (try out different colors, double-up on your creation rate, etc.), this is something I expect a lot of other 3D printers to be adopting soon.
But just as easily, these two nozzles can be used on the same product, either filling in a support filament or going for the multi-color approach.
It almost feels unfair constraining this 3D printer to a list like this… all thanks to its Swiss-Army Knife-Like variety of functions and capabilities.
How long does it take to assemble?
The D3 Pro comes half assembled and it took me 30 minutes to put it together with the help of videos online.
What I didn’t like was the printer didn’t come with a lot of instructions.
The printer is not dead silent and there’s a low humming noise from the fans. However, it’s noticeably quieter than my Ender 3 Pro.
The prints so far are very good and I have better results with custom stl files than the test files from Tenlog.
There are cheaper dual color/extruder 3D printers out there but this is the most affordable INDEPENDENT dual extruder (IDEX) 3D printer today.
All in all, this is the best multicolor 3D printer.
- Image-mirroring capabilities
- Easy setup and assembly
- Included warranty
- Runs quietly
- Poor customer service
- Requires filament in both extruders

XYZPrinting Da Vinci Color (Best Full Color 3D Printing for its Price) 3D Printer Type: FFF | Materials: 3D Color-inkjet PLA , PLA , Tough PLA , PETG, Carbon Fiber & Metallic PLA | Build Volume: 200 x 200 x 150 mm | Print Speed: 180mm/sec | Color Mixing (Y/N): Y | Extruder: Single
This super-popular 3D printer is probably the first one you’ll see when you search for a personal-use full-color 3D printer.
And there’s a good reason for that.
The da Vinci Color is one of the first (if not the first) personal printers to offer full color printing.
While this 3D printer still has its bugs, it can offer a 3D printing design experience that’s miles ahead of almost any other 3D printer on the list.
The Da Vinci’s full color capabilities mean creators have almost total control over every aspect of their design, including the exterior color design.
Gone are the days of painting by hand; with the right schematics, you can print just about any design imaginable.
The 3D printer also comes with hands-free calibration, which can significantly reduce the amount of time you spend fiddling with the da Vinci Color.
And while I didn’t have enough time to experiment with this feature as extensively as I might have liked, it seemed to work very well for the few prints I tested.
To note: this printer comes in the regular size – which I looked at here – and a miniature version that is basically a scaled-down version of the original da Vinci Color.
- Full color 3D printer capabilities
- Hands-free calibration features
- Excellent color palette
- Very pricey
- Some issues with ink cartridge technology

FlashForge Creator Pro (Most Reliable) 3D Printer Type: FDM | Materials: PLA, ABS, PETG & TPU95A | Build Volume: 227 x 148 x 150 mm | Print Speed: 100 mm/s | Color Mixing (Y/N): Y | Extruder: Dual
Yet another excellent dual extruder 3D printer, the FlashForge Pro, takes the shape of the enclosed-box design, whereas the other dual extruders on the list have all been open-air.
Aesthetically, this has always been my favorite design, though it has its positives and negatives in more objective terms.
Like the previous 3D printer, the FlashForge Creator is a dual-nozzle design, though it doesn’t have the independent-nozzle functionality (and the image mirroring).
However, it does have a substantial metal frame and faster printing on single objects than the two independent heads.
On top of that, the enclosed design allows for better temperature control, and less potential warping as a result.
However…
… FlashForge went the distance with its design, also allowing for increased ventilation options if you’re printing with PLA.
Finally, the reliability of the Creator Pro’s build plate shouldn’t be overlooked.
By and large, issues with build plates, leveling, and covers have been the most prevalent issue I’ve had with printing.
Having a solid, completely level plate was a wonderful change for me.
- Enclosed environment
- Excellent built plate
- Great filament variety
- Some nozzle clogging
- No automatic bed-leveling

XRize Rize (A Look-See at an Industrial Full Color 3D Printer) 3D Printer Type: FFF with AMD | Materials: Rizium Carbon, GF (Glass Filled), ST (Semi-Translucent), Rizium One White & Black, CMYK Inks & Release Ink | Build Volume: 310 x 200 x 200 mm | Color Mixing (Y/N): Y
This one’s just on the list for fun (unless you’re a large-scale industrial manufacturer, of course).
That said, it’s interesting to look at the difference in the price points of desktop-style multicolor 3D printers and an industrial-grade model full color 3D printer like the Rize.
So how much does the Rize cost?
Well, as you can see from its listing, you’ll need to request a quote to find the exact cost.
However…
… what I can tell you is that based on some of the other sites I looked at while conducting preliminary research, the price should fall somewhere around $55,000 – brand spanking new.
And believe me, that isn’t even close to being the most expensive full color 3D printer on the market.
A full color 3D printer can set you back a dime or two.
So what do you get out of one of these color 3D printers that you’ll miss in one of these other, comparatively affordable versions?
For a start off, this full color 3D printer has a precision and control over their 3D print products that nothing else on my list can come close to.
Like the da Vinci Color (one of our most expensive desktop 3D printers besides the Rize), this printer uses Inkjet toner (the same as a traditional 2D printer) to externally bind colors to the filament as it prints.
However…
… with a full color 3D printer of this price, you can expect much, much better color control than anything you’ll get from the DaVinci.
This color 3D printer can also print logos, QR codes… literally anything you can imagine slapping on the side of a 3D printing; this Rize can make it happen.
It’s awesome.
This full color 3D printer also comes loaded with all sorts of extra features that make it suitable for industrial production: a heated build chamber, automatic filament swapping and digitally-encoded ink cartridges, to name a few.
More than anything, the XRize is interesting because it provides us with a potential roadmap of what a future desktop 3D printer will be trying to emulate.
After all…
… the evolution of desktop 3D printer technology usually aims to copy the best capabilities of industrial best 3D printers, but on a smaller, less-expensive scale, of course.

Yet another awesomely robust dual-extrusion 3D printer?!
The Qidi Tech iFast is an industrial and engineering-grade that’s much more affordable than other printers of its caliber.
With a super spacious build volume of 330 x 250 x 320 mm, you can make a whole lot of medium to large-sized objects.
It has in-built air filters providing thorough ventilation, which makes it ideal for indoor use.
This printer can print PLA, ABS, TPU, PETG, Nylon, carbon fiber, and water-soluble PVA for supports.
It also has a double Z-axis for double the precision! Okay, that sounded right out of an infomercial. Anyway. (It’s still true!)
The Qidi Tech iFast comes with a whopping 4 direct extruders! That’s 2 extruders for normal-temperature filaments like PLA and 2 high-temp extruders for nylon and other toasty materials.
This printer also comes with a removable build plate for easy part removal. It has a filament run-out sensor to detect when filament… well… runs out, and it’s also got a camera for remote viewing of your print!
We loved the large touchscreen — it helped us easily navigate controls and get set up quickly.
The printer also has WiFi capabilities so you can easily send your print file.
It also comes with a heated enclosure which is perfect for higher temp filaments like ASA, nylon, and PBS.
We found that the stepper drivers were a bit noisy when using this printer. Also, this printer is only compatible with Qidi’s own software, which isn’t as robust as say, Cura or Simplify3D. Also, it doesn’t come with auto bed leveling but with a sturdy printer of this type, it’s not that necessary.
This printer also comes with a 2 year guarantee and round-the-clock tech support. If you’re a pro who wants a mid-range printer with high-end capabilities, go for the Qidi Tech iFast.
- Very robust and professional quality printer
- 4 extruders
- Air filters
- Large build volume
- Noisy printing
- Would be better with standard 3D printing software

Add-Ons
While there are plenty of color 3D printers that can handle multi-color print jobs within their basic design, others need some help.
Nowadays, one of the best ways of getting excellent and low-cost multi-color creations is using a multi-color add-on for color 3D printers. These tend to cost less than getting a new printer altogether and are compatible with plenty of models (though you should always research the cross-compatibility before you order one).
9. Mosaic Palette 3 Pro (Best Color 3D Printing Add-On)
3D Printer Compatibility: Accepts Non-Proprietary Filament Which is 1.75 mm in Diameter & Recognizes Files Sliced in Slic3r/PrusaSlicer or CANVAS, and Has Open Access to Filament Feed | Materials: PLA, ABS, PETG, TPU, PVA & HIPS | Extruder: On
Want to make a glorious color explosion with your 3D printer? Or have you been dreaming of multi-color capabilities but don’t want to get another 3D printer?
Introducing the Mosaic Palette 3 Pro!
This awesome doo-dad isn’t a printer in itself but rather a device that you hook up to your existing printer to give it multi-color capabilities.
With the Mosaic Palette 3 Pro, you can print up to 8 different colors and materials at once — kind of like a multi-colored filament octopus.
With the Palette 3, you can print breakaway or soluble supports using different materials, allowing you to easily tackle difficult overhangs.
To get started printing, place spools on the filament stand and feed them individually into the material inputs on the device. It kinda sounds like something out of Star Trek, but it’s simple enough when you get the hang of it!
What the Palette 3 Pro then does is it heats and splices filaments together into a single multi-filament strand.
It comes with Canvas Hub software for remote monitoring of your print. So even when you’re not nearby, you can see how things are going!
The Palette 3 also has a high-resolution touchscreen where you can execute commands and change settings. Nice!
This device has three color printing modes: Gradient Mode (for an awesome gradient/ombré effect), Pattern Mode which enables you to print patterns, and our personal favorite, Random Mode! Which is a bit like throwing paint at the wall blindfolded.
(Our favorite pastime outside of 3D printers.)

Multicolor VS Full Color 3D Printers
Source: Youtube XYZprintingI want to start with a pretty important distinction when talking about 3D printers that can print in multiple colors.
Sometimes “full color” is a term used to describe these printers.
And while this is technically true, “full color” more often describes industrial-grade printers that are able to produce intricate color scaling and manipulation (I included one of these on the list – the XRize Rize – for comparison’s sake).
On the other hand…
… we’re going to be mostly looking at multicolor 3D printers, which can usually handle only a small number of different colors, but which tend to fall under the “personal 3D printer” umbrella.
They’re smaller and much, much less expensive.
All that said, multicolor printing is still a very experimental field – much less established than its industrial counterparts.
Given the scarcity of personal 3D printers that can handle multiple colors, I’m going to be looking at every option on the market today, including dual-extruder printers where each extruder can print a separate color and multi-color printer upgrades.
So let’s take a look at the best multicolor 3D printers!
Can 3D Printers Do Multiple Colors?
Source: Youtube 3D Printing Nerd3D printers can do multiple colors! However, the method varies between printers.
Single-extruder printers rely on a method of manually switching out spools of filament, while multi-color printers do this process for you.
What is a Multi-Color 3D Printer?
A multi-color 3D printer is a device that 3D prints different filaments using multiple extruders and nozzles.
Advantages and Disadvantages of Multi-Color 3D Printer
The obvious advantages of a multi-color 3D printer: you get awesome multi-colored prints without having to manually swap filaments. Also, such printers are compatible with water-soluble filaments for easy support removal.
The disadvantages: twice the extruders, twice the maintenance. Hot end assemblies can run into any number of issues — and dealing with two of them can be a hassle. Also, it’s much more expensive than a single-extruder printer.
How Do You Print Two Colors?
If you have a single-extruder printer, you can pause and swap.
What does this mean?
Well, whenever you want to change colors in a print, you just stop the print and swap the filament.
This can be a major chore, however, and with multi-color printers the process is much easier.
First, you load your two spools onto the spool holder, and then you feed the filament into the printer. Then you just let it do its multi-colored magic!
Can You Paint 3D Printed Objects?
Yes, you definitely can!
Acrylic and enamel paints are best for 3D printed surfaces. However, you’ll have to sand your 3D printed part first. This gets rid of visible layer lines and helps the paint stick better to the surface.
A Few Final Thoughts…
So there you have it – a fairly comprehensive guide to multi-color 3D printing, the best (affordable) multicolor 3D printers out there, one crazy-expensive one, and an alternative option altogether!
When it comes to choosing your best color 3D printer, there are plenty of factors to keep in mind.
When making your decision, you should always consider what specific projects you have in mind and tailor your choice to fit.
After all, if you’re looking to upgrade towards multicolor 3D printing, you probably have a couple of exciting ideas in the bag already.
Some of these 3D printers excel at color combining.
For color control, the Da Vinci provides an entirely different system from anything else on the list (besides the XRize) but does so at a higher price point and with a few concerning bugs.
Some color 3D printers come packed with excellent side features, like the Lotmaax Shark V3.
And others have an ingenious design that comes with other exciting applications, like the dual-nozzle design of the TenLog.
Anyway, your preferences will determine your best color 3D printer, so I’ll hand over the baton to you to make your choice.
You’ll be churning out those colorful 3D prints before you know it.
Our pick
LOTMAXX Shark V3
Great 3D printer for beginners
This printer cranked out quality prints right out of the box in our test.
Comes with excellent, all-metal nozzle and extruder and many more features makes this the best value.

Source: Youtube Dylan HongSo this was kind of an underdog story for me. When I first started looking for the best color 3D printer, the Lotmaxx wasn’t even on my radar.
Yet the more I learned about this 3D printer, the more I was impressed – both by its original design and by its execution. Not to mention that it’s a Kickstarter success and really demonstrates the best aspects of grassroots ingenuity coming out of the color 3D printing field.
Not only is the Lotmaxx an excellent base 3D printer capable of color 3D printing, but it also comes with some innovative features that I haven’t seen in a single other color 3D printer.
The laser engraving upgrade opens up new doors in creative design. The auto bed-leveling works pretty well, and the handheld removable touch-screen is something I haven’t seen in any other 3D printers, no matter what price point.
And to speak on the price… all of this costs less than $500.
Typically, when I review 3D printers by newly-launched companies or Kickstarter campaigns, I’m overwhelmed by a sea of mechanical, software, and assembly issues. I had none of these with the Lotmaxx.
In fact, the only persistent issue I had with this color 3D printer came from the build plate adhesion.
In some cases, my recent prints would require a lot of elbow grease and some light chiseling to remove the prints from the plate. This is one of the most straightforward issues to remedy, though, so it’s not even something worth criticizing.
So there you have it!
Whether you choose the Shark or some other color 3D printer on the list (XRize, anyone?), multicolor 3D printing opens up many new avenues for you and your creations.
In a field where companies and creators are innovating every day, I can’t wait to see what new color 3D printer awaits us! Until then, thanks for reading, and happy printing!
3D printer prints multi-colored filament from different materials
Engineers have introduced a new technique for printing colored plastic objects on a simple 3D printer with a single nozzle without the use of additional tools.
To do this, it is necessary to print a thread consisting of colored segments in the right places in several steps, and then you can use this filament for conventional printing by layer-by-layer deposition. In addition to color, the method also allows you to create a thread from different materials. Article published at ACM Digital Library .
The most common and affordable 3D printing method is Fused Deposition Modeling (FDM). FDM printers have one (sometimes more) extruder that supplies filament to the substrate, and to print multi-colored objects, you either need to change the filament spool manually, stopping the printing process, or print on a printer with several extruders, or use additional devices to thread several threads at once. Printing with two extruders increases the chance of shearing, welding and other defects, and these defects are also difficult to avoid when manually changing the filament. In addition, manual replacement may be required several times during the printing process, which can greatly increase the time spent and increase the likelihood of printing defects.
Accessories, on the other hand, need to be bought separately, and they often require certain skills and training, complicate and increase the cost of printing. There are also multi-color threads and materials that can change their color and properties, but these are not universal solutions that are usually not available to the average user. nine0007 Haruki Takahashi of Meiji University and colleagues have come up with a low-cost method for printing filaments of different colors and even materials on a printer with only one extruder. The method involves the creation of a programmable thread for each individual project using a 3D printer, which is then fed into the 3D printer as a regular filament. The length and number of required segments is generated in G-code format from a 3D model or 2D image using printer software. nine0005
A program developed by scientists uses this G-code to design a future filament and offers optimal printing options. The printer sequentially prints the filament in the form of a spiral, starting from the edge towards the center.
First, all segments of one color are printed, and only then another, which significantly reduces the number of manual filament changes. The ends of the segments are cut diagonally during the printing process to increase the contact area between the segments, and are additionally fused with stitches - additional layers of filament. Fusing the stitch and simultaneously passing a hot nozzle at the point of contact increases the strength of the connection. nine0005
The scientists tested their technique on four different printers using filaments of different colors and different materials: polylactide, thermoplastic polyurethane, acrylonitrile butadiene styrene, polyvinyl acetate, nylon. One of the samples printed with the programmable filament consisted of five colors, which is difficult to achieve using even multi-extrusion machines. In addition, the engineers printed a model of a watch that combines a solid base and a flexible strap, proving the possibility of using materials of different composition in their technique.
nine0005
The researchers plan to refine their method in further studies and study the mechanical behavior of composite structures in more detail, as well as increase the strength of connections between heterogeneous materials. Already at this stage, the filament stitching technique provides good joint strength, reduces the cost and simplifies the printing process.
Recently, we wrote about another way to simplify the post-processing of 3D printed materials - this is the addition of a catalyst to the plastic to facilitate subsequent metallization. nine0005

3D printing filaments
Hello friends!
This article would like to highlight the appearance of threads in printing. I will try to note the main factors influencing the appearance of threads.
1) Idling speed and acceleration.
The idle run consists of the following stages - first there is a retract, then the movement of the extruder, then again a retract. The plastic is spontaneously squeezed out precisely during the idle time, forming various kinds of defects. Now imagine an example if the idling takes zero seconds. Under this condition, the plastic will not have time to spontaneously extrude. Therefore, the higher the speed and acceleration, the less time the idling lasts, which means there will be fewer threads. But speed and acceleration are limited by the motor driver, the motors themselves, and the rigidity of the printer frame. nine0005
Therefore, you can try to slightly increase the speed and acceleration with each print, but at the same time make sure that the motors do not overheat, otherwise microsteps may be skipped, which will lead to print rejects.
2) Idling path. Different slicers process parts according to different algorithms, which means that the idling trajectory may differ.
Some slicers build more rational extruder motion than others. Therefore, you can try to prepare the same part in several slicers and stop at the option that will be more rational. nine0005
3) Feeder dependent, i.e. from the plastic supply system. Printers most often have one of two options: "bowden", i.e. far-distance or "direct", this is when the "feeder" is located near the extruder. Under the same printing conditions with direct, there will always be fewer threads than with bowden. But this does not mean that you can always switch from Bowden to Direct. It may also be that your printer will not be able to work with "direct" for one reason or another. The transition to "direct" must be considered with each printer individually. nine0005
4) Retract setting, i.e. plastic rollback - its task is to remove the residual pressure in the extruder during idling. Without retract, the threads will appear more intensely. For most printers, the values are as follows - for direct, the range is from 1 to 6mm, and for bowden, from 4 to 12mm.
(the amount of retract also depends on the diameter of the nozzle).
5) Plastic quality. If you are constantly printing only budget plastics and are unhappy with the result, then try to buy plastic in a higher price category, and more importantly, with good reviews. And then compare the print quality. But the main thing - from different manufacturers, compare the same types of plastic - you should not compare, for example, ABS from one manufacturer, and PLA from another. nine0005
6) Plastic drying. By the way, this applies to almost all plastics, not just nylon. If you have unnamed or cheap plastic in your hands, it is recommended to dry it after opening it, because. it is not known whether the plastic was dried before packaging.
7) Nozzle diameter. The larger the diameter, the more plastic will spontaneously squeeze out during idling. There is nothing you can do about it, it just needs to be taken into account when choosing a nozzle diameter.
8) Extruder temperature.
If you heat the extruder to the upper limit of the recommended range (indicated on the plastic that is being printed), then the fluidity of the plastic will be higher, and it will be more easily extruded from the nozzle. Plastic manufacturers give a temperature range for a reason. If you set the print speed to high, then the extruder temperature should be in the upper limit of the range. But if the print speed is low, then there is no need to heat up the extruder much, otherwise filaments may appear due to overheating of the plastic. nine0005
Therefore, you can try to reduce the temperature of the extruder as follows - during printing, every couple of minutes, reduce the temperature by 5 degrees over and over and watch the print closely. If the threads disappear, remember the temperature and stick to it. But if the temperature is greatly lowered, then the plastic will not be able to extrude at all. Don't overdo it.
9) Dependence of temperature on the type of extruder. There are many different models of extruders.
For example, consider the E3D V6 and E3D V6 Volcano extruder. The E3D V6 Volcano has an extended nozzle and an extended aluminum block. And this means that the zone where the plastic is in the molten state is larger, so it can push through a larger volume of plastic per unit of time. As a result, this extruder will be able to print at higher speeds than the regular E3D V6. But here you need to understand the following - if you have a "powerful" extruder, and you print at low speeds, then the plastic will overheat, which will lead to the appearance of threads. Therefore, for powerful extruders, it is better to set the temperature in the lower limit of the recommended range. And on the contrary - for an extruder that cannot heat up a large amount of plastic, the temperature should be kept in the middle or at the upper limit of the recommended one. nine0005
The conclusion here is the following - for different models of extruders, different printing temperatures are needed.
10) Free travel distance.
If you are printing multiple parts at once, try to space them closely to reduce the dry travel distance. Well, if a solid part is printed, with individual elements at a great distance from each other, in this case, you can try to change the location of the part in space so that there are fewer idle moves.
11) File analysis before printing. When your G-code is ready, do not be lazy and meticulously analyze it before printing, because. at the verification stage, you can detect unwanted elements that can create various kinds of defects, including the appearance of threads. By the way, no matter what slicer I use to prepare the file, I almost always check the finished code using “Repetier-Host”, because it shows all the movements that can lead to certain defects.
12) Plastic type. All plastics have both strengths and weaknesses. For example, PETG plastic has a high tendency to filament. ABS, on the other hand, has a low predisposition to threads, but it will have to concentrate on the problem of shrinkage and a low degree of sintering of the layers.
nine0005
Therefore, before printing, familiarize yourself with the pros and cons of the plastic with which you plan to print.
13) Using the "Lift Z" function. When enabled, a gap will be created between the extruder and the printed part. It is needed so that during idle the extruder does not cling to the outer walls of the part. This feature can significantly reduce the number of threads. But it should be used if the printer has a powerful driver and a motor along the Z axis, as well as a screw with a thread pitch of at least 8mm. This is necessary to achieve high speed and acceleration on the Z axis. Well, if you try to use this function at low speeds, the problem will only get worse and there will be more threads, because. idle time, taking into account "Lift Z", will increase greatly. The idling time with the "Lift Z" function consists of: movement along the Z axis + retraction + idling + retract + movement along the Z axis. nine0005
Therefore, you can try to experiment with this function and see the result.
14) Problems with the extruder. Imagine a situation where you put a large retract, but a large plug of melted plastic formed in the thermal barrier between the nozzle and the Teflon tube. In such a situation, no matter how big you put the retract, this plug will not disappear, but will remain in its place. And, therefore, the retract will not be able to completely relieve the pressure in the system. Therefore, keep your extruder clean and in good working order. nine0005
15) Problem with the driver on the motor in the feed system (motor on the feeder). It's a rare phenomenon, but it's still there. I've run into a problem where the driver only spins the motor in one direction, regardless of the command, whether it's spinning one way or the other -- the motor only spins in one direction.
And in practice it looks like this: the motor advances the plastic during printing, and at the moment of idling, when a retraction should occur, the motor sharply squeezes out additional plastic (because the driver rotates the motor in only one direction).
