Delta Vs Cartesian 3D Printer – Which Should I Buy? Pros & Cons
You’re presented with countless variations to choose from when it comes to picking a 3D printer. One such case is where you have to decide between a Delta or a Cartesian-style 3D printer.
I faced a similar hassle and experienced nothing but tough luck for a long while. That is why I’m writing this article to make the decision easier for you.
If you’re after simplicity and speed, I suggest a Delta 3D printer while on the other hand, Cartesian-style printers bring the best of quality with them if you go for one, but you’ll have to spend a bit extra on these.
In my opinion, both of the printers are exceptional, and choosing between the two ultimately boils down to your personal preference and budget. The main difference between these two 3D printers is the style of movement.
The rest of the article will guide you on which 3D printer to choose at the end of the day. Therefore, continue reading for an in-depth analysis of both printer types, how they work, and what are the pros and cons of each.
What is a Delta 3D Printer?
Delta-style printers are gradually on the rise to popularity, as an exceeding amount of these machines continue to deliver beyond expectations. You’ve probably heard more of Cartesian printers making the headlines, but that’s not all there is to 3D printing.
Delta printers are unique in movement. They are structurally engineered in such a way that they adapt to a triangular shape, thus the name “Delta”.
Unlike Cartesian-style printers who are fashioned according to the XYZ coordinate system in Mathematics and follow those three axes, Delta printers consist of three arms that only move up and down.
A great example of a Delta 3D printer is the Flsun Q5 (Amazon) which has a touchscreen and an auto-leveling feature to make life a little easier.
Nevertheless, what’s exclusive about these printers is the individual motion of the arms that are directly in contact with the extruder, allowing it to print in all directions seamlessly. Nothing short of a visual phenomenon, to say the least.
On the contrary, when Delta and Cartesian printers go toe to toe against each other, you’ll find that they mostly have the same components, only the placement is different.
Both run common thermoplastic filaments like PLA, ABS, PETG comfortably and you probably wouldn’t be able to guess a Delta-style finished 3D print from a Cartesian one.
However, there are key differences to shed light on too. Speed, for one, is where Delta printers excel and shine.
No doubt that they are built with heavy parts and a solid extruder, but they’re kept on the sides and the actual printhead doesn’t take up too much weight. This allows them to move swiftly and as accurate as they are, these are made with pace in mind.
Want to know the best part? Quality doesn’t even suffer one bit. You got that right, Delta 3D printers are known to produce some of the most amazing quality prints you’ll ever see, all in good time.
Moreover, these printers have a circular build platform, unlike the standard rectangular ones you see on Cartesian printers.
In addition, the beds are kept much smaller as well, apart from the fact that they are considerably taller than other types of 3D printers. Lastly, the print surface does not move and remains stationary for the whole of the print job.
This is a trademark that applies only to Delta printers where Cartesian ones are highly different in this regard.
What is a Cartesian 3D Printer?
Cartesian 3D printers are no joke either. You’ll be amazed at what these machines are capable of in a genuinely distinctive approach.
Speaking of their mode of action, these printers are based on the Cartesian coordinates system, which was formed by the French philosopher René Descartes.
Simply put, the three axes that make up the foundation of Cartesian printers’ working mechanism are X, Y, and Z.
A great example of a Cartesian 3D printer is the Ender 3 V2 (Amazon) which is a very popular 3D printer that is loved by both beginners and experts.
There are some notable differences in varying printers but generally, you’ll observe that these machines take up the Z-axis as their main driving focus, with a two-dimensional peripheral work on the X and Y-axis.
This way, the printhead attributes back and forth, up and down, and left and right movements. This might seem a little bit complicated, but Cartesian 3D printers are much simpler and more user-friendly than Delta-style ones.
There’s one more thing worth adding here. The mode of the mechanism of these printers might not change for many printers, but there are still heavy differences in how they work in several printers.
Taking into account the LulzBot Mini, it has got the build platform moving back and forth on the Y axis, while the printhead delivers by moving up and down. Finally, the movement of the X-axis is associated with the gantry, and that’s that.
On the other hand, there’s Ultimaker 3 whose build platform moves upwards and downwards, unlike the LulzBot Mini where it moves back and forth.
Additionally, the X and Y axes are controlled by the gantry here as well. All this goes on to show that there are substantial variations in Cartesian 3D printers where they might not be what you are anticipating about them.
What makes these axis-driven printers so sought-after is their minimalistic design and easy maintenance due to the simple mechanics involved. However, all that comes at a cost, and that is speed.
As the printhead isn’t as light as it is in Delta variants by far, fast directional changes can’t happen without them ruining your print.
Therefore, you have to compromise speed with Cartesian printers, but it’s safe to say that the outcome is very well worth the wait.
Indeed, the accuracy, precision, detail, and depth are unmatched by any other printer type however long may that take you.
Cartesian printers are famous for prints of the highest standard with intricate, detailed delicacy. Delta printers fall short and bow down in defeat in terms of a quality standard, therefore.
This is mainly because of high rigidity in the axes of these printers, purely paving the way for a lesser room for error.
Pros and Cons of a Delta 3D Printer
Let’s delve into the part where I tell you the major advantages and disadvantages of owning a Delta 3D printer. Let’s start with the pros first.
The Pros of a Delta 3D Printer
Delta printers are acknowledged as one of the fastest 3D printer types out there. They are known to produce prints very quickly and with great quality as well.
The rate at which they print can go as up as high as 300 mm/s, which is quite insane for a 3D printer. Maintaining such speed, these highly admired machines do their best to deliver fantastic quality with satisfactory details.
Made with rapid production in mind, Delta-style printers aren’t going to run out of fashion for a very long time. They’re truly for those who have a short turnover time and their businesses demand such efficiency.
Therefore, it’s like these printers are built to handle this challenge and complexity. This is one of their major plus points and genuinely hard to overlook when buying a 3D printer.
Technically speaking, Delta printers owe their speed to the courtesy of three stepper motors working the three vertical arms individually.
It means that it has three motors powering the XY plane movements rather than two for Cartesian 3D printers.
In addition, most of these have the Bowden extrusion setup, which takes the extra weight off the printhead, making it lightweight and invulnerable to jerks while quick directional changes.
Compared to a Delta printer’s counterpart, Cartesian printers are most likely to print at approximately a fifth of 300mm/s. You can call this a tricycle going up against a Bugatti. No competition.
Great for Making Tall Prints
Delta printers may have a small print bed but that doesn’t mean it’s of no use. To compensate for the lack of sizeable volume, the makers urged the people to look at things in a different light.
In doing so, they’ve built the print bed’s height to an exceptional level, making it eminent for producing tall models.
When it comes to printing towering architectural models, there’s no better printer out there than Delta-style ones.
This is because the three movable arms can travel a good distance both up and down, enabling them towards catering to large models effortlessly.
A Circular Print Bed
The fact that the build surface of Delta printers is in a circular shape is truly special and dedicated to them. This gives these types of printers a hefty advantage over some situations, especially when you have to make rounded, circular prints.
A nice feature, if you ask me.
Another major difference that draws a fine line between Cartesians and Deltas is the movement of the print bed. In Delta printers, the bed remains stationary and fixed, providing a more compact and beneficial experience in several cases.
Reduced Moving Weight
This advantage is how speed is levels above a Cartesian 3D printer. There is a lot less moving weight so you can have quicker moves without the inertia, or vibrations negatively affecting print quality.
It also leads to great accuracy in the centre of the print bed as compared to the outer sides.
Easy to Upgrade & Maintain
Although troubleshooting can be difficult, the actual upgrading and maintaining of a Delta 3D printer is fairly easy, and doesn’t require all sorts of complex knowledge of your 3D printer.
You do have to keep in mind that the Delta print head has to be light, so you don’t want an aftermarket print head which weighs too much, as it can start to dig into your print quality.
They Look A Lot Cooler
I had to throw this pro in there. Delta 3D printers just look way cooler than any other types of 3D printers. The bed stays still, yet the three arms are moving in unusual ways, slowly building your 3D print in an interesting way.
The Cons of a Delta 3D Printer
A Lacklustre of Precision and Detail
Not everything goes right with the Delta printer. It may have unparalleled speed and prompt mass productions, but there can be a significant sacrifice on precision and detail.
Speed can come at a cost especially if things aren’t fine-tuned, but even though it still holds up pretty well in terms of quality, the difference is apparent when faced off against a Cartesian-style 3D printer.
Surface detail and texture can suffer to a good extent as well. You may notice roughness here and there when you’re finished printing and all this is mainly from decreased precision.
Limitations with the Bowden Extrusion Setup
The Bowden-style extrusion may be great and all, removing excessive weight off the printhead and allowing it to print more swiftly, but there are caveats associated with it.
First off, as the Bowden setup uses a thing, long PTFE tube, you’re going to have trouble when printing with flexible filaments such as TPU and TPE.
Flexible thermoplastics are known to cause wear and tear inside the PTFE tubing which leads to deformation of the filament. This, in turn, can cause clogging and obstruct the extrusion process.
However, all this doesn’t imply that you can forget about printing with such a filament using a Delta printer, no.
It only means that you’ll have to be careful about a lot of factors, tune your printer with great regard, and master the art of making relentless attempts.
Small Build Platform
The build platform is circular and you can probably print a tower inside, but the size is limited and this is something vastly important to consider.
Truth be told upfront, if you don’t intend to make tall, narrow models with a Delta printer and only seek to create other types of regular models, take into thought very closely the small build platform when buying this hunk of metal.
Again, it’s not going to be impossible, but you’ll have to divide your model into separate parts and print them likewise. This, obviously, is more work as compared to printing on a Cartesian printer.
It’s perfect if you need to build tall objects which don’t have a large horizontal size. The great thing is you can divide your models and make better use of your 3D printer’s height with a Delta 3D printer.
Another key con to appraise the Delta-style 3D printer on is it’s developing, currently small-scale community that don’t have the same level of support, advice and communication that the Cartesian community has.
Delta 3D printers are more known to run into troubleshooting issues, so this, mixed with a lesser support channel could be a bad combination. There are several users who love their Delta 3D printers, so I wouldn’t let this factor deter you so much.
Additionally, the Delta printer fanbase isn’t flooded with content, blogs, how-to tutorials, and thriving communities just yet, so you’ll have to have a good grasp on 3D printer mechanics, the necessary settings, and of course, the assembly.
You won’t have as many of those cool upgrade videos on YouTube and new projects such as the super-sized 3D printers, but you’ll still be able to do the main functions that you need.
If you are just starting out in the field of 3D printing, you may run into problems of troubleshooting, but honestly, you’re going to get that with most 3D printers at some point down the line!
It’s just part of the hobby that you’ll get used to.
Harder to Troubleshoot
Since the three arms of a Delta printer move in a parallelogram and extrude while changing angles, the mechanics of a Delta 3D printer are a little more complex than a Cartesian.
This results in print imperfections and reductions in print quality being harder to figure out and troubleshoot.
You want to make sure you assemble a Delta 3D printer almost perfectly, or you might need to do regular calibration, which is especially difficult with the long Bowden tubes.
For newcomers, calibrating a Delta machine can be quite challenging.
Pros and Cons of a Cartesian 3D Printer
Here’s why Cartesian-style printers are exceedingly principled and well-liked among the diversity of 3D printers. Side by side, the cons are also there for you to reckon with.
The Pros of a Cartesian 3D Printer
Immense Community and Far-Flung Popularity
Probably the most tremendous advantage of owning a Cartesian 3D printer is its popularity and robust community to draw from.
The main reason behind the success of these printers is their glaring popularity, allowing them to be very user-friendly, arriving at your doorstep fully pre-assembled, awesome customer support, and a terrific fanbase to consult with.
With some Cartesian 3D printers, assembly can take only 5 minutes!
You’ll find a plethora of generous experts out there fervent to answer your questions and help you troubleshoot your Cartesian printer. At no point in owning this type of 3D printer, you’ll find yourself alone.
Furthermore, as they require a simple setup, get ready to start printing with these mavericks as soon as they are out of the box.
Detail and Precision
Cartesian 3D printers are a class above Delta ones when you talk about the precision. This attribute is up there in the top rankings unequivocally, as the detail is something that matters the most in 3D printing.
Fortunately, Cartesian printers have such a mode of mechanism that allows them to perform with a depth effect while drawing each line with power and accuracy.
These might be slower than Delta printers but that’s all for good reason- terrific print quality. Models are known to have smooth texture with clear definitions- quality traits that are highly desired in the 3D printers of today.
A fine-tuned Cartesian 3D printer can bring you some seriously amazing print quality, especially if you get a high quality extruder and hotend combination.
The Hemera Extruder is a great option. You can check out my E3D Hemera Extruder Review here.
Another advantage that roots from the widespread popularity of Cartesian printers is the abundant availability of spare parts, both cheap and expensive- whatever that fits the scenario.
There’s a huge market online that’s yearning for you to make Cartesian printer purchases, often offering great deals and massive discounts as well.
For an example of the kind of parts you can easily get, check out my Ender 3 Upgrade article or my 25 Best Upgrades You Can Do On Your 3D Printer.
Great Compatibility of Printing
With a good Cartesian 3D printer, you are able to 3D print more materials easily, especially those flexible materials such as TPU, TPE and soft PLA. You may have a little trouble printing those same filaments on a Delta 3D printer.
You can easily convert your Cartesian 3D printer to a Direct Drive setup to reap the rewards of printing flexibles more accurately, and faster.
Check out my article about Direct Drive Vs Bowden 3D Printer Setups for more detailed information.
The Cons of a Cartesian 3D Printer
As the printhead of Cartesian 3D printers is large and heavy, it builds up momentum as it moves along to draw the print lines. In doing so, it’s only sensible to foresee that it cannot change direction instantly and print at a fast pace.
That would only ruin the print quality instead because you cannot hope to stop and turn very quickly if you have great momentum. This is one of the disadvantages of a Cartesian printer and you can see why it’s not built for speed, unlike its rival.
You can still get a pretty high speed, but nothing matching a solid Delta 3D printer.
Delta 3D printers can instantly change their direction, but Cartesians need to slow down before moving, related to your Jerk & Acceleration settings.
High Weight on 3D Printer
This is also linked to the speed, where the higher weight limits the amount of fast movements you can commit to without reducing print quality. After a high enough speed, you will start to notice ringing in your 3D prints.
There are methods to reduce the weight, but it won’t be as light as a Delta 3D printer due to the design of the machine. The fact that the print bed also moves contributes to the higher weight.
People have seen bad print quality from having a heavy glass build plate because of the movement.
Should You Buy a Delta or Cartesian 3D Printer?
On to the real question here, which printer should you go for then? Well, I guess it’s not that hard to determine by now.
If you’re a seasoned veteran who’s looking for a different challenge and already knows the ins and outs of 3D printing, Delta 3D printers will keep you happy and satisfied with their remarkable speed and reasonable quality.
They’re also going to cost you less and give you tons of functionality.
On the other hand, if you’re fairly new to 3D printing and still getting used to the basics, prepare yourself to spend a bit extra and get a Cartesian-style 3D printer.
This thundering monster truck of a printing machine is a breeze to set up, surrounded with cheerful people to help you on your 3D printing journey, and produces insanely good quality- all at a trivial price of speed.
Oh, and don’t forget how these printers are flexible in filament variety and will let you print with different thermoplastics painlessly.
In conclusion, buy whatever that seems more suited to your needs since Delta and Cartesian printers both are the best at what they do. There are noteworthy differences in the two of them, so this is where your own taste comes into play.
We just recommend to check out the pros and cons before making the purchase.
What About a CoreXY 3D Printer? A Quick Review
A relatively new foray into the realm of 3D printing is a CoreXY 3D printer. It uses the Cartesian motion system but comprises belts in which the two separate motors rotate in the same direction.
These motors on the X and Y-axis are kept unchanging and constant so the moving printhead doesn’t become too heavy.
CoreXY 3D printers are mostly cube-shaped while the belt and pulley system incorporated in them distinguishes them from other printers in terms of length.
Moreover, the build platform has its movement in the vertical Z-axis atypically and the printhead does the magic in X and Y-axis.
What can concern you about a CoreXY 3D printer is its unanticipated advantages over other FDM printers.
For starters, the stepper motor that amounts to all the weight on the moving part is fixed, and the tool head is exempt from any attachments. This makes a CoreXY 3D printer print at unbelievable speeds while catering to quality in every possible way.
There’s no worrying about recurrent printing mishaps like ghosting and ringing as well.
Therefore, this supersized stability is what keeps CoreXY 3D printers at a top-notch level. Adding to their pros is the compatibility with almost every popular firmware and great quality print results.
Beware though, a printer of such category requires you to be exorbitantly careful about its assembly.
This mainly involves two facets – frame assembly and appropriate belt alignment. When your printer’s frame is off point, the dimensional accuracy of your prints is bound to suffer radically.
This is followed by a boatload of issues arising from wrongful belt alignment and cheap counterparts that stop working halfway.
All in all, a CoreXY 3D printer measures to be a breath of fresh air for many enthusiasts and professionals out there. It may set you back a bit higher compared to other printers, but at the end of the day, it lives up to the expectations.
To sum it up, these printers are a great alternative for Delta and Cartesian-style ones and pose a promising future.
