Kobra S1 Combo Multicolor 3D Printer with ACE PRO, 4 Color | Drying and Printing at the Same Time, 600mm/s Fast Speed with 320℃ Hotend, Built-in Camera 44dB Quiet 250*250*250mm

The Anycubic Kobra S1 has been a big step up for me coming from older machines. Unboxing took some time — most of the instructions are actually about carefully removing and unlocking everything packed inside. I also bought the version with the 4-color add-on, which was secured inside the machine. It’s impressive how well they fit everything in one box, but expect setup to take a few hours rather than the quick start the manual suggests. Build quality is outstanding and a huge improvement over my older XYZ and Monoprice printers. Once assembled and you get familiar with a few small nuances, it’s very easy to use. The phone and PC apps make it simple to browse thousands of premade models and start prints quickly. Print quality is top notch. I’ve logged about 300 hours without a failed print yet. Speed is solid as well, though multi-color printing slows things down since each color switch adds time and waste. If your project allows layers of a single color in sequence, it helps minimize both. The printer is quiet, reliable, and large enough to handle up to ~11" objects on the diagonal — plenty of room for most projects. Maintenance is minimal, usually just wiping the plate with an alcohol wipe before each run. One quirk: the machine “poops” a bit of filament out the back each time it primes. Luckily, a free “poop chute” design is available in the app to redirect the scraps. Overall, the Anycubic Kobra S1 is well worth the price. The combination of build quality, print reliability, and ease of use make it an excellent choice for anyone looking to step up from older entry-level printers, though keep in mind that multi-color printing trades efficiency for aesthetics. Strongly recommended.

I am very disappointed with this purchase. I am not new to anycubic products. I have 3 photon mono x resin printers that still go strong to this day. I have the M3 resin printer which is even better, and i have the Kobra plus which i loving call my beast. I have never regretted any anycubic product tell i got the S1 combo. I bought it cause i was interested in its capability to print up to 8 colors. I purchased the combo 1st the purchased an additional ace pro so i could upgrade it to 8 colors. However out of the box was non stop issues. The printer itself is great. Anycubic excels with its printers. However where this falls short and the reason for the 1 star is the ace pro. Out of the box it had issues reading filament. I got it working but that was only temporary then the “broken” or “abnormal filament” errors kept happening on one of the ports no matter what filament was used. Tech support tried to help but nothing they suggested seemed to work. They aggreed to replace the ace pro (which im still waiting on a return label since they wont replace it tell they recieve the original one back). In the mean time my second ace pro arrived. Out of the box it seemed great. I didnt have the same issues but 11 percent into the print the filament jammed in the buffer. The machine did not stop it just started grinding. I shut it off manually and agter all i went through with the 1st unit quickly found the problem. The buffer was practically exploded from 1 jam. So that is 2 ace pros and not a single full print on this machine. The small parts of the main print that you could see looked awesome. But, 2 ace pros have not lasted long enough to complete 1 job. So, if you are looking for a 4 color printer i cant recommend anything that uses the ace pro. To me that thing is garbage. Im hoping i get a replacement for the first and get the buffers to repair the second and get this running and maybe it will get a better review later. But as of now unless the ace pro gets serious revamping it’s not worth the aggravation to buy this machine.

Bunch of 11511 errors, even with new filaments, spent 3 hours to finally get a print to start, print didn't stick to bed so ended up having to use a glue stick. for $600.00 bucks I expect it to work. Seems anycubic doesn't even bother to check out what they are shoving out the door, so far my impression of this machine is it is solid built. Just plan on some start up problems. Update 3/15/2026 Anycubic support is great and has taken care of the few minor problems I have had, my machine has 750 hours on it and still is going strong, I ended up adding a second Ace Pro and I did upgrade the carriage and bed to the funnsor kit and have not had a failed print since. The Kobra S1 is a solid well built machine and handles any print job I throw at it. It is well worth the money and really don't see why there is alot of negative reviews on youtube.

I bought this about 4 months ago. I have close to 500 hours on it now. I have had failed prints, which more or likely was my fault. The only issue I have had is the nozzle dropped out and destroyed the plate but Anycubic sent all new replacement parts for it. As far as the multi color printing goes, it does it well but does waste a lot. Its not a bad printer for a first multicolor. A lot of bad reviews/videos I have seen on it, I would say comes down to lack of servicing the machine, after all it does have a lot of moveable parts.

Prior to this purchase, I have been using my Creality CR6-SE for 4-5 years with great success, but I wanted to start doing multi-color printing. Like many of you, I read some worrisome reviews and held off buying the Anycubic Kobra S1 Combo until just recently. Now that I've used it for a few weeks, including doing multi-color printing of my own (Openscad-based) designs, I thought I'd write a review and let you know I find this printer to work wonderfully with PETG (which is what I always use). Mine was delivered by Amazon's "heavy item" team and arrived in great shape. No dents or other issues. Assembly was easy and I took my time to make sure I did it all correctly. I felt the instructions were clear and adequate. My first prints of the Benchy failed due to poor bed adhesion, but I then washed the bed with Dawn detergent and hot water and haven't had any issues since. I do wash the bed now and then, just to be safe. I've printed some pretty challenging, small, multi-color keycaps that really came out great. See photo. These have very fine text lines that need good bed adhesion and I'm very impressed with the results. I've also printed some large items (adapters for small 250g reels) and didn't have any warping or lifting (with brims turned off). The ACE Pro has worked well with cardboard reels so far, but I do intend to print the thin plastic "rims" to avoid the potential of cardboard dust creating some issue down-the-road. Some people have complained about this or that, but I think it's easy to configure the ACE Pro with generic filaments and you can also set the order the colors are printed in the slicer and adjust the purge waste. There are two places you set the bed type. The first one seems stuck on "Smooth Plate", but scrolling down there is another place to select "Textured PEI". I adjust PETG to print at 240C rather than their default 230C which seems a bit too cool in my experience. I have found the bed-levelling to work well almost every time. Strangely, a couple times it somehow started with "zero" Z so that the nozzle basically scraped the build plate, but did no harm. I can't explain how/why this can happen, but it did. I just aborted the print and restarted and the auto-leveling worked fine on the second try. I certainly suggest you monitor your print jobs as they start and see that all is well. When you gain more experience with your machine then you might launch print jobs remotely with your phone, but that's not my workflow. BTW, I don't use Anycubic cloud service to print. The Anycubic Next slicer is able to connect to my home Wi-Fi network and I can submit print jobs directly from the slicer. So, this is a great printer and seems really well built to me. I'm fine with the clear/lexan/lucite door and top cover. Glass would have just made the machine even heavier. Also, I've directly compared prints from the Kobra S1 Pro and a Bambu Labs and I'd say they're equivalent.

The reason I give 4 stars originally is I had received this printer that day and it's missing a few screws the build plate is damaged where it looks like the print head had contacted it. I know it has two sides but getting a newish machine this is sad. I am missing one blue lock which I have those. The main feed line had filament and the head was clogged. I have no idea what had happened to the power cords but they are missing the grounding part of the power cords. I don't want to sound negative, I do really like the brand. I do have other anycubic resin printer and wash and cure 3. No issues. I try to print my first print and found the print head tip was floppy so I removed the cover and silicone sock and found the assembly was broken just below the heat sink and it looks like the part was damaged with pliers. Even if I have to buy a new print head/ heat sink assembly I do like how there is plugs so the whole cable don't need to be un routed and re strung disassembling the whole machine like I had to with my ender 3. I do like the build quality otherwise my pettyish issues and know that I didn't spend the 700 plus dollars so it may be refurbished. The head and pei bed plate damaged is sad but I do see a lot of potential. Even though my first print after installing the new hot end assembly had failed i see the intermittent 40-60mm/sec. And then when I see the detail of what is being printed I am feeling a whole lot better. I recommend all anycubic things I had played with so far. As hard as I had tried to make this thing work I had to return because no matter what I had tried this device would not do anything consistently. I think out of a dozen or so attempts I got 2 benchy. I wanted this to work but when you received a return for nearly 700 and it was damaged like it was this was a red hand from the start. I am somewhat disappointed with fdm at this time. I still think my 40 dollar anycubic photon mono 2 that I bought on Facebook market place is the best printer I had experienced. I had returned this and mabe in the future I may try again with the fdm setup.

This is my second S1 and first with an ACE. I already have two Bambu Lab printers. I was so happy with the S1 that I got this one instead of committing further to the Bambu Lab ecosysem. Set up is really easy if you can follow the directions and basically prints perfect right out of the box. The biggest thing for me is the consistent quality of the prints. I haven't yet had a badly failed print that I didn't cause myself. This is by far a better value than the A1 in at around the same price. The Core XY means really consistent prints at higher speeds than possible on a bed slinger since your print isn't flying back and forth at high speeds. The ACE has been great so far on the few prints I've done with it, and I like how much easier it is to load filament over the AMS lite from Bambu Lab. I also like the small footprint and the overall look of it. The only thing I'd change is to make the front panel clear rather than smokey so I can see the progress at a glance. Since I only print in PLA I'm toying with the idea of just removing the doors completely. Anycubic is new so there are some trade offs that I didn't expect coming from the Bambu Lab A1. Namely getting parts is slow so order replacement nozzles and stuff long before you actually need them. Also the firmware out of the box is bad. Really bad. Lots of connectivity issues and it's riddled with poor spelling and grammar. These are minor as they have already improved a lot in the latest releases and they will likely improve further. And finally the printer is slow to start... it spends a lot of time leveling and preheating before getting to that all important first layer, but the annoying thing about the pre start is that you can't cancel it until it actually starts. So when I send a job and have that "oh crap I forgot something moment" you're stuck waiting. Overall I am very happy with the printer and hope that it has the longevity and reliability that I need.

Very easy to set up and operate. I have used the touch screen, My computer, and My phone app and they all worked perfectly. Its nice to start prints using the phone app. I'm impressed with the speed and quality of the Kobra S1.
