Can you imagine going from an idea in your head to a physical object in your hands at a speed that until recently seemed like science fiction? 🤔 That is the fulfilled promise of the Anycubic Kobra S1, a printer that has arrived to change the rules of the game in FDM 3D printing thanks to a brutal balance between speed, precision, and a price that breaks the market.
Opening the box: what does this FDM revolution hide inside? 📦
Filament 3D printing has evolved enormously. For years, those of us in this world have faced a complicated decision: either you settled for slow and affordable printers, or you made the leap to fast machines that cost you an arm and a leg. The Anycubic Kobra S1 has come to put an end to this dilemma. 💥
It is no coincidence that this printer has made its way into the workshops of novice makers and professionals who need to produce in series. The reason? It is simple: it solves the typical frustrations of FDM 3D printing in one fell swoop and delivers quality parts before you even have time to get bored waiting.
Why all the fuss about the Kobra S1?
What hooks you about the Kobra S1 is not any single thing, but the intelligent combination of technologies that work together perfectly. It is a machine built for action. So you can forget about endless adjustments and start printing from minute one.
- Speed that leaves you speechless: 💨 Say goodbye to those projects that drag on forever. Its ability to print at very high rates drastically reduces waiting times.
- Truly easy to use: 👍 From an assembly that practically puts itself together to an automatic leveling system that works first time. Everything is designed so you spend more time creating and less time fighting with the machine.
- Quality that is never sacrificed: ✨ Speed is useless if the parts come out poorly. Its robust metal structure and quality components guarantee that every layer comes out clean and precise.
The real magic of the Anycubic Kobra S1 is that it has democratized high-speed 3D printing. It has put within everyone's reach a capability that, until quite recently, was reserved for much more expensive industrial equipment.
To get off to a good start, you are going to need materials that are up to the task. Such a powerful printer deserves quality consumables. If you want to experiment, you can even compare with some resin for 3D printers if you have that type of machine. Having a good selection of filaments for 3D printing is key to bringing your projects to life exactly as you imagined them.
In the following sections of this guide, we are going to break down every detail of this beast. We will analyze its specifications, walk you through your first print step by step, and give you the best tips to get the most out of your Anycubic Kobra S1. Get ready to print faster and better than ever! 😉
Analysis of its key technical specifications 🤓
The technical datasheets of 3D printers can be a jumble of numbers and acronyms, right? 🤯 Do not worry. We are here to translate those figures from the Anycubic Kobra S1 into real benefits you will notice in every print. We are going to set aside the jargon and explain what all of this means for your projects, with clear and straightforward examples.
The Kobra S1 has been a true game-changer in the 3D printing market in Spain. Its maximum speed of 600 mm/s places it among the elite of FDM 3D printers. This, combined with a brutal acceleration of 20,000 mm/s² and a closed CoreXY structure, guarantees stability, minimizes vibrations, and enables precise prints even at breakneck speeds. In fact, as mentioned in this Muy Interesante article, its impact has been considerable.
Formula 1 Speed and Acceleration 🏎️
The two numbers that make the biggest impression are its maximum speed of 600 mm/s and its acceleration of 20,000 mm/s². To put it in perspective, a standard FDM 3D printer typically moves between 50 and 80 mm/s. The Kobra S1 is not just a little faster; it plays in a completely different category.
Think of a prototype that would normally take you 10 hours to print. With the Kobra S1, you could have it in your hands in under 2 hours. Incredible! This changes the rules of the game for professionals and makers, allowing you to iterate designs and produce parts at a pace that was previously unthinkable.
Speed without control is worthless. That's where acceleration comes into play. It's the 3D printer's ability to reach that peak speed and brake sharply on the curves without sacrificing precision. Such high acceleration is what prevents the ghosting effect (those ghost shadows on the edges) and keeps details sharp.
This chart perfectly summarizes the balance Anycubic has achieved: an incredibly fast and precise machine, but without the price skyrocketing.
As you can see, the 3D printer sacrifices neither precision nor cost to deliver class-leading speed. An option with extraordinary value.
To visualize why the Kobra S1 represents a generational leap, we have put together this comparison table.
Anycubic Kobra S1 vs. Standard FDM Performance Comparison
| Feature | Anycubic Kobra S1 | Standard FDM 3D Printer |
|---|---|---|
| Maximum speed | Up to 600 mm/s 🚀 | 50-80 mm/s |
| Acceleration | 20,000 mm/s² 🔥 | 1,000 - 3,000 mm/s² |
| Structure | CoreXY (more stable) ✅ | Cartesian (moving bed) |
| Leveling | Automatic LeviQ 3.0 ✨ | Manual or semi-automatic |
| Hotend Temperature | Up to 320 °C 🌡️ | 240-260 °C |
As you can see, the difference is not small. The Kobra S1 is designed from the ground up to deliver performance that traditional 3D printers simply cannot match.
CoreXY Structure and Print Volume
To move at those speeds without falling apart, the Kobra S1 uses a CoreXY structure. Unlike typical Cartesian designs, where the bed moves back and forth, here the bed only moves vertically. The printhead handles all movement on the X and Y axes thanks to a more complex but immensely more stable belt system.
And what advantages does this bring us?
- Less vibration: By not having to drag the mass of the bed and the part, inertia is drastically reduced. The result is much cleaner prints.
- Precision at high speed: The printhead, being lighter, can make extremely fast and precise direction changes without losing quality.
- Enclosed structure: Helps maintain a constant internal temperature, which is key if you want to print with technical materials like ABS or ASA.
As for its print volume, the Kobra S1 offers a work area of 250 x 220 x 220 mm. It's an ideal size: large enough for most projects (helmets, prototypes, scale models) without needing a huge workshop.
High-Temperature Hotend and Automatic Leveling
The heart of any FDM 3D printer is its hotend, and the one on the Kobra S1 is ready for action. It can reach up to 320 °C. This opens the door to a world of materials that goes far beyond PLA. You'll be able to print with no trouble using PETG, ABS, ASA, TPU, and other filaments for 3D printing that require higher temperatures.
Last but not least, we have the LeviQ 3.0 automatic leveling. If you've already dealt with other 3D printers, you know what a nightmare manually leveling the bed can be. With the Kobra S1, you can forget about that headache. Its system measures 49 points across the surface and automatically compensates for any irregularities. This ensures that the first layer is perfect, which is 90% of the secret to a successful print. It's as easy as pressing a button and you're done! ✅
Your First Successful Print in Less Than 30 Minutes 🥳
The moment of truth has arrived! You have the box of your brand-new Anycubic Kobra S1 in front of you and it's time to move from excitement to action. Forget endless manuals or videos that confuse you. This guide is going to walk you through everything so you can get your first printed part done in less than half an hour. Trust me, the process is much easier than it looks.
Let's break everything down into short, straightforward steps. The goal is to take you from "now what?" to "this is amazing!" in the blink of an eye.
Quick and Hassle-Free Assembly
Anycubic has put real thought into the design of the Kobra S1 to make assembly a breeze. The 3D printer comes 90% pre-assembled, which means almost all the work has already been done for you. Your mission comes down to just a few steps that won't take you more than 15 minutes.
- Attach the Z frame: Simply screw the vertical frame to the 3D printer base. Don't worry, the screws and tools come in the box. Tighten it well so nothing wobbles!
- Connect the cables: All connectors are labeled and foolproof. You just need to plug each cable into its slot. Impossible to get it wrong.
- Assemble the spool holder: Last up is placing the holder where your filament roll will sit. A couple of screws and you're done.
A pro tip: when assembling the frame, place the 3D printer on a flat, stable table. Tighten the screws in a cross pattern, as if you were changing a car tyre. This ensures the joint is perfect.
One-click LeviQ 3.0 automatic calibration
This is where the Kobra S1 really shines. If you've wrestled with other 3D printers before, you'll know that leveling the bed can be a real nightmare. With the LeviQ 3.0 system, this process is fully automatic.
When you turn on the 3D printer, look for the "Leveling" option on the touchscreen. Once you tap it, the machine will spring to life: the print head will gently probe 49 different points across the surface. What it's doing is creating a map of any minor imperfections to compensate for them during printing.
This is key, because a well-adhered first layer is 90% of the battle. With LeviQ 3.0, you eliminate one of the biggest headaches in 3D printing.
Loading the filament and launching the test print
With the 3D printer assembled and calibrated, all that's left is feeding it. Loading the filament is straightforward:
- Preheat the hotend: In the menu, find "Preheat" and select the temperature for PLA (usually between 200-210 °C).
- Insert the filament: Cut the tip of the filament at a 45° angle so it feeds in more easily. Press the extruder lever and push the filament in until you feel the gear catch it.
- Purge the material: Keep pushing gently until you see a thin strand of melted plastic come out of the nozzle. You're all set!
And now, the magic moment. On the SD card that comes with the 3D printer you'll find a test file (usually the famous "Benchy"). Just select it on the screen and press "Print".

Within minutes, you'll watch your Anycubic Kobra S1 start drawing the first lines of your object. Congratulations, you're officially a maker! 🚀
How to choose the perfect filament for every project 🎨
Think of your Anycubic Kobra S1 as a blank canvas. One of its greatest strengths is its incredibly powerful hotend, which reaches up to 320 °C. This opens the door to a universe of materials. No more being tied to a single filament type; with this machine, the only limit is your creativity.
We're going to show you how to navigate the world of materials like a pro. We'll explain the when and the why behind each one. Need a mechanical part that can handle heat? Or a quick, affordable prototype? Every project has its perfect material.
Let's break down the most common materials so your choice is always the right one.
PLA: the king of ease and prototypes
PLA (Polylactic Acid) is the material almost all of us start with, and for good reason. It's biodegradable, prints beautifully and doesn't give off any strange odors. It's the ideal option for decorative figures, prototypes and parts that won't be put under significant stress.
- When to use it: Great for your first prints, artistic models, scale models and prototypes.
- Printing temperature: Ranges between 190 °C and 220 °C.
- Heated bed: 50-60 °C is more than enough.
PETG: the perfect blend of strength and simplicity
If PLA falls short for you, the logical next step is PETG (Polyethylene Terephthalate Glycol). It's the bigger, tougher sibling of PLA. It offers superior mechanical and chemical resistance and handles heat better. It's fantastic for functional parts that need to last.
- When to use it: Supports, electronics enclosures, mechanical parts that don't need to withstand extreme loads.
- Printing temperature: Around 230-250 °C.
- Heated bed: Raise it to 70-80 °C so the first layer adheres properly.
ABS and ASA: the champions of toughness and heat 💪
Now we're entering the territory of more technical materials. ABS (Acrylonitrile Butadiene Styrene) is the plastic used in LEGO bricks, so you already have a good idea of its robustness. As for ASA (Acrylonitrile Styrene Acrylate), it's almost ABS's twin, but with one key advantage: it's UV-resistant.
The Kobra S1, with its enclosed structure, is ideal for printing these materials, which tend to suffer from warping (when the corners lift up).
- When to use it: Car parts, outdoor components, tool enclosures and anything that needs to withstand heavy use.
- Printing temperature: 240-270 °C for the hotend and a well-heated bed at 90-110 °C.
- Key recommendation: Always print with the door closed!
Choosing the right filament can make the difference between a part that breaks on first use and one that lasts for years. Think about the final function of your object before hitting print.
TPU: flexibility for your creations
Finally, we have TPU (Thermoplastic Polyurethane), a flexible material, like a hard rubber. It's perfect if you're looking to create parts that can bend, stretch or absorb impacts. Thanks to its direct extruder, the Kobra S1 works very well with these filaments.
- When to use it: Phone cases, gaskets, robot wheels, shoe soles...
- Printing temperature: Usually in the range of 220-240 °C.
- Golden tip: Print slowly, at around 20-40 mm/s, to avoid jams.
If you're hungry for more, we recommend taking a look at our complete guide on how to choose filament for your 3D printer, where we go into much more detail. Getting the material right is the first major step toward success.
Tips to optimize your prints and avoid mistakes ✅
OK, so you've got your Anycubic Kobra S1 assembled and you've printed your first pieces. Congratulations! 🥳 Now the fun begins: the journey from beginner to mastering 3D printing. This section is your cheat sheet for getting the most out of your machine, fine-tuning every detail, and dodging the most common mistakes.
We're going to dive deep into slicers, maintenance, and those little tricks that make all the difference. The goal is to find the sweet spot between breakneck speed and quality that leaves everyone speechless.
Print profiles in Cura and PrusaSlicer
The slicer is the conductor of your printer's orchestra. Programs like Cura or PrusaSlicer are incredibly powerful, but the sheer number of options can be overwhelming. Don't worry — the trick is to start with the default profiles and customize them gradually.
For your Kobra S1, we suggest starting with these basic settings:
- Layer height: For maximum detail, try 0.12 mm or 0.16 mm. If you're looking for speed, start with 0.2 mm or 0.28 mm.
- Speed: Even though this printer is a rocket, for PLA it's better to start steady, between 150–250 mm/s. You'll have plenty of time to put your foot down later. 🚀
- Retractions: Key to avoiding stringing (those little plastic threads). With a direct extruder, a distance of 0.8 mm to 1.2 mm and a speed of 40 mm/s usually works like a charm.
Don't be afraid to experiment. Duplicate a profile that works for you and change only one parameter at a time. Run a small test print (a calibration cube is perfect) and analyze the result. That's how you learn.
Diagnosing and solving common problems
Any 3D printer, no matter how good, is going to throw some challenges your way. The Kobra S1's blistering speed can make certain issues more noticeable. Here are the most common ones.
1. Stringing or "angel hair" 🕸️ These are the fine threads that connect different parts of your model.
- Why does it happen? The filament leaks from the nozzle while it travels through the air.
- How do I fix it? Increase the retraction distance or speed slightly. Another option is to lower the print temperature by 5 °C.
2. Ghosting or ringing 👻 These look like ghostly echoes or vibrations after corners.
- Why does it happen? They're vibrations from the machine when changing direction at full speed.
- How do I fix it? Although the CoreXY structure helps, if it appears, try reducing the acceleration slightly in the slicer. And make sure the printer is on a solid surface.
If you run into other headaches, we have a comprehensive guide on the most common 3D printing errors and how to fix them that's sure to get you out of more than one tight spot.
Preventive maintenance and silent mode
To keep your Kobra S1 performing like it did on day one, a little regular maintenance is essential. It'll barely take any time at all.
- Bed cleaning: A cloth with isopropyl alcohol after each print works like a charm.
- Belt inspection: Every 50-100 hours of use, take a look at the belts. They should be neither too loose nor too tight.
- Lubrication: The linear rails need a thin layer of lithium grease from time to time.
Lastly, one of the gems of this 3D printer is its silent mode. At just 44 dB, the noise is comparable to that of a library. 🤫 Great if you have the 3D printer at home or in the office.
Conclusion: it's time to push your Kobra S1 to the limit 🔥
As we've seen, the Anycubic Kobra S1 is much more than your average 3D printer. It's a true beast that redefines what we can expect in its range: blistering speed, jaw-dropping precision, and incredible ease of use.

Answering your questions about the Anycubic Kobra S1 🤔
So you can start printing without any doubts, we've put together the questions almost everyone asks when getting started with the Anycubic Kobra S1. These are straightforward, no-nonsense answers.
Which slicing software or Slicer do you recommend for the Kobra S1?
The Kobra S1 works brilliantly with the most well-known slicers. To start, I'd say play it safe with AnycubicSlicer (based on PrusaSlicer) or the ever-popular Cura. Both usually come with ready-made profiles for this model that work great right from the start. 💻
Will printing with ABS or ASA be much of a challenge?
Not at all. Thanks to its enclosed chamber and high-temperature hotend, the Kobra S1 makes things much easier than open 3D printers. The main challenge is maintaining a stable temperature and managing ventilation properly to avoid warping. My advice: start with small parts and follow the manufacturer's recommendations.
What maintenance does it need to keep it running without problems?
Maintenance is very straightforward, but key to keeping the 3D printer running smoothly for a long time.
- Keep the print bed clean. A little isopropyl alcohol works wonders.
- Keep an eye on belt tension from time to time.
- Lubricate the linear rails every few hours of use.
A little care goes a long way toward reliable, quality prints.
Can I use the Kobra S1 to print highly detailed miniatures?
Of course! Although resin printers are usually the queens of minis, the Kobra S1 can give you results that will leave you speechless. You just need to fine-tune the settings. To get the most detail, the trick is to use a smaller nozzle (a 0.2 mm one), lower the speed, and carefully adjust your slicer profile. 🎯
✨Happy Printing! 🚀
