Anycubic Kobra S1

Name: Anycubic Kobra S1
Brand: Anycubic
SKU: 1563

Manufacturer: Anycubic

The Anycubic Kobra S1 is a pre-assembled FDM 3D printer designed for users who want to get started without lengthy setup. It supports a range of common filament materials including PLA, ABS, PET, and PETG, and is capable of producing prints in up to 4 colors per print, making it a versatile option for multi-material output. The printer weighs 18,000 g and fits within a footprint of 400 x 410 mm with a height of 490 mm.

On the technical side, the Kobra S1 reaches a maximum print speed of 600 mm/s and uses a single 0.4 mm nozzle with 1.75 mm filament diameter. Its build platform is heated and features automatic bed leveling, while the minimum layer thickness is 80 µm across a maximum creation size of 250 x 250 x 250 mm. Connectivity options include Wi-Fi 4 (802.11n), a single USB port, an RJ45 port, and an external memory slot, with remote smartphone support also available. The printer includes a 4.3″ touch screen, power loss recovery, and operates at an audible noise level of 44 dB with a rated operating power consumption of 325 W. A 1-year warranty is included.

Pros

Comes pre-assembled, so no setup time is required before first use
Automatic bed leveling removes the need for manual calibration
Supports up to 4 colors per print, enabling multi-color output in a single job
Reaches a print speed of 600 mm/s, which is notably high for an FDM printer
Offers multiple connectivity options including Wi-Fi 4, ethernet, USB, and an external memory slot, as well as remote smartphone support
Power loss recovery allows interrupted print jobs to resume rather than restart from scratch

Cons

Does not automatically generate support structures, requiring manual handling of overhangs in slicer software
Layer thickness is fixed at 80 µm with no finer resolution option listed in the specs
Limited to a single extruder head, which constrains multi-material printing flexibility
The maximum build volume of 250 x 250 x 250 mm may be restrictive for larger print projects
Warranty period is limited to 1 year

Who is this for?

The Kobra S1 is well-suited to users who want to start printing without spending time on assembly or manual calibration, as it arrives pre-assembled with automatic bed leveling. Its support for PLA, ABS, PET, and PETG filaments, combined with multi-color printing of up to 4 colors per job, makes it a practical fit for hobbyists and makers working on visually varied or functional prints. The broad connectivity options — including Wi-Fi, ethernet, USB, and remote smartphone control — also suit users who prefer flexible workflow management from different devices.

Who is this NOT for?

Users who need to print large-scale models will find the 250 x 250 x 250 mm build volume limiting, as it cannot accommodate oversized parts in a single run. The printer is also less suited to those requiring fine surface detail, since the minimum layer thickness is fixed at 80 µm with no finer resolution option available. Additionally, the single extruder head and lack of automatic support structure generation make it a poor fit for complex multi-material prints or geometrically intricate designs that rely heavily on software-controlled support strategies.
