Overview
The Kobra S1 Combo is a fully enclosed CoreXY printer bundled with the ACE Pro four-slot filament unit, with a 250 x 250 x 250 mm build volume, 320°C hotend and 120°C bed. Anycubic lists PLA, PETG, TPU, ABS and ASA support, a built-in camera and noise around 44 to 46 dB. The original combo is sold out on the official store, replaced in the lineup by the Kobra S1 ACE 2 Pro Combo.
What it is
The Anycubic Kobra S1 Combo is a fully enclosed CoreXY FDM printer sold with the ACE Pro, Anycubic's four-slot filament unit with active drying. The official store lists a 250 x 250 x 250 mm build volume, a short-distance extruder, a 320°C hotend and a 120°C bed. Connecting a second ACE Pro and the eight-color hub enables eight-color printing.
As of October 2026, every Kobra S1 Combo variant on Anycubic's global store is marked sold out. Anycubic now sells the Kobra S1 ACE 2 Pro Combo, which its page describes as the Kobra S1 Combo enhanced version. That bundle pairs the same printer with the newer ACE 2 Pro, which dries filament at up to 65°C (versus 55°C for the first ACE Pro) and scales to 16 colors with four units. Anycubic notes that the two generations of ACE units cannot be mixed.
Key specs that matter
- Build volume: 250 x 250 x 250 mm.
- Motion: CoreXY, with 600 mm/s maximum speed, 300 mm/s recommended, and 20,000 mm/s² maximum acceleration.
- Temperatures: 320°C hotend and 120°C PEI spring steel bed. Anycubic does not list active chamber heating.
- Nozzles: 0.4 mm standard, with 0.25, 0.6 and 0.8 mm options. Layer heights of 0.05 to 0.28 mm are listed for the 0.4 mm nozzle.
- Materials: PLA, PETG, TPU 95A (not through the ACE Pro), ABS and ASA. The FAQ adds high-temperature materials such as PC, PA, and carbon or glass fiber filled filaments.
- Monitoring: A built-in 480P HD camera supports AI spaghetti detection and time-lapse, with LED chamber lighting.
- Noise: Anycubic lists 46 dB or less in standard mode and 44 dB or less in quiet mode.
Who it suits
The Kobra S1 Combo suits buyers who want multicolor printing and an enclosure in one machine. The enclosure and 320°C hotend make ABS and ASA practical, which open-frame multicolor printers struggle with. The listed noise figures and included camera also make it a reasonable fit for a home office or shared room where the printer runs unattended.
What to know before buying
- Stock: The original combo is sold out on the official store. If you want a new unit from Anycubic, the Kobra S1 ACE 2 Pro Combo is the in-stock version, listed at $499 with a 4-color unit.
- Filtration: An activated carbon filter is listed in the box, and Anycubic sells an AirPure accessory separately. Ventilation is still worth planning for ABS and ASA.
- Size: The printer measures 400 x 410 x 490 mm and weighs 18 kg. The ACE Pro adds a 4.6 kg unit about 366 x 283 x 235 mm.
- First setup: Anycubic's FAQ describes PID tuning, feedback compensation and auto-leveling on first startup, taking about 10 minutes.
- Multicolor limits: Color changes go through a single nozzle, so each swap purges filament. TPU cannot be fed through the ACE Pro.
- Network details: The spec table lists printer, slicer, Anycubic app and USB control, but does not spell out Wi-Fi bands or Ethernet.
- Warranty: Anycubic lists a 1-year printer warranty, a 14-day no-reason return and a 30-day after-sales guarantee.

Pros and cons
Pros
- The fully enclosed CoreXY frame and 320°C hotend support ABS, ASA and other warp-prone engineering materials.
- The bundled ACE Pro provides four-color printing with active filament drying up to 55°C while printing.
- A built-in 480P camera enables AI spaghetti detection, remote monitoring and time-lapse without extra purchases.
- Anycubic lists noise of 46 dB or less in standard mode and 44 dB or less in quiet mode.
- A 120°C PEI spring steel bed and LeviQ 3.0 auto-leveling simplify adhesion and setup.
- Nozzle options from 0.25 mm to 0.8 mm cover both fine detail and fast, thick-layer printing.
Cons
- Every Kobra S1 Combo variant is sold out on Anycubic's official store as of October 2026.
- The first-generation ACE Pro tops out at 55°C drying and cannot be mixed with the newer ACE 2 Pro.
- TPU cannot be fed through the ACE Pro, so flexible filament is limited to single-color jobs.
- Eight-color printing needs a second ACE Pro plus a separate hub, adding cost and desk space.
- Anycubic does not list active chamber heating, so the enclosure is passive for high-temperature materials.
- The 250 x 250 x 250 mm volume is smaller in height than some open-frame printers in the same class.
Frequently asked questions
Is the Kobra S1 Combo still available?
All Kobra S1 Combo variants are marked sold out on Anycubic's official store as of October 2026. Anycubic now sells the Kobra S1 ACE 2 Pro Combo, which it calls the enhanced version of the S1 Combo.
Can the Kobra S1 Combo print ABS and ASA?
Yes. Anycubic lists ABS and ASA as supported filaments, and the FAQ mentions PC, PA and fiber-filled materials as well. The enclosure helps limit warping, and Anycubic includes an activated carbon filter in the box.
How many colors can it print?
Four colors with the included ACE Pro. Adding a second ACE Pro and the eight-color hub allows eight colors. TPU 95A is supported only for single-color printing because it is not compatible with the ACE Pro.
Does it have a camera?
Yes. Anycubic lists a built-in HD camera that supports 480P video, used for remote monitoring, time-lapse and AI spaghetti detection. No separate purchase is needed.
How loud is the Kobra S1?
Anycubic's spec table lists 46 dB or less in standard mode and 44 dB or less in quiet mode. These are manufacturer figures, and real-world noise depends on speed settings and placement.

Verdict
The Kobra S1 Combo suits buyers who want an enclosed multicolor printer that can also handle ABS and ASA, if they can find a new unit. Since the official store lists it as sold out, most buyers should look at the Kobra S1 ACE 2 Pro Combo, which uses the same printer with a newer drying unit.
