Serious 3D Printing, Without the Fuss

The Anycubic Kobra S1 is a fully enclosed CoreXY FDM 3D printer built for makers, hobbyists, and professionals who want fast, reliable results without constantly babysitting their machine. Powered by Kobra OS and packed with smart automation features, it brings high-speed printing, broad material compatibility, and intelligent print monitoring together in a single, capable package.

Speed and Precision Locked In by CoreXY

Tired of watching slow, lumbering printers grind through complex models? The Kobra S1’s CoreXY construction, driven by linear rod motion on both X and Y axes and a single-motor three-pole Z-axis, delivers smooth, stable movement at a recommended 300 mm/s — with a maximum ceiling of 600 mm/s and up to 20,000 mm/s² acceleration. Pressure advance and flow calibration are built in, so what comes off the bed reflects what you designed, not what the printer could manage.

A Hotend That Handles What You Throw at It

With a maximum nozzle temperature of 320°C and a PEI spring steel heated bed reaching up to 120°C, the Kobra S1 supports a broad material roster — PLA, PETG, TPU, ABS, and ASA — without requiring an upgrade. The standard 0.4mm nozzle handles everyday printing, while compatibility with 0.6mm and 0.8mm nozzles gives you flexibility for faster, rougher or more detail-focused work. The source material notes the hotend is designed for easy disassembly and clog-free performance.

Smart Monitoring Keeps Your Prints Safe

The Kobra S1 watches over every job so you don’t have to. AI Spaghetti Detection spots failed prints early and can halt the job before filament becomes a tangled mess. Filament runout detection pauses the print and waits for you to reload, filament entanglement detection flags spool issues before they cause a failure, and power loss resume picks up exactly where it left off after an unexpected outage. A built-in HD camera supporting 480P video monitoring means you can check in remotely via the Anycubic APP over Wi-Fi. LeviQ3.0 auto-levelling and Z-Offset adjustment handle bed calibration automatically, and object-skip with area levelling adds further precision control.

Quiet, Connected, and Easy to Control

At as low as 44dB in Quiet mode, the Kobra S1 is considerate of its surroundings — a real advantage when printing long overnight jobs. The 4.3-inch capacitive touchscreen gives you direct, responsive control on the printer itself, while slicing software, the Anycubic APP, and USB connectivity round out your options. The interface supports nine languages, making it accessible whether you’re setting it up for the first time or handing it to a colleague.
