Anycubic Kobra S1 MAX 3D Printer

Large-format CoreXY speed | Engineering-grade filament support | AI-powered print monitoring | Fully automatic bed levelling

Quick Specs

• Print at speeds up to 600 mm/s across a generous 350 × 350 × 350 mm build volume — tackle large, complex projects with confidence.
• Achieve precise, repeatable results every time with LeviQ3.0 automatic bed levelling and built-in pressure advance and flow calibration.
• Print with over a dozen filament types — from everyday PLA and PETG to engineering-grade PA, PC, and carbon-fibre composites — thanks to a 350°C hardened steel nozzle.
• Stay in control from anywhere: monitor, manage, and start prints via the Anycubic App, slicing software, or the onboard 4.3-inch capacitive touchscreen.
• Work quietly and confidently — AI spaghetti detection, filament entanglement sensing, and power-loss resume keep long prints on track without constant babysitting.

Big builds, serious speeds — without the compromise

The Anycubic Kobra S1 Max 3D Printer is built for makers, engineers, and creators who need a large-format FDM 3D printer that can keep up with ambition. With a 350 × 350 × 350 mm³ build volume and a CoreXY motion system capable of reaching 600 mm/s (recommended 300 mm/s) at accelerations up to 20,000 mm/s², it handles everything from rapid prototyping to production-scale batch runs — without sacrificing print quality.

Print more materials, solve harder problems

Tired of a 3D printer that locks you into a handful of basic filaments? The Kobra S1 Max supports thirteen filament types, spanning everyday PLA and PETG all the way to demanding engineering materials like PA, PC, PA6-CF, PC-CF/GF, and PET-CF. A hardened steel nozzle rated to 350°C and hardened steel extrusion gears handle abrasive carbon-fibre and glass-fibre composites without wearing down, while a PEI spring steel build plate (max 120°C) gives prints solid adhesion and easy release.

Set it up once, print with confidence every time

Getting the first layer right shouldn’t take an hour of fiddling. The Kobra S1 Max integrates LeviQ3.0 automatic bed levelling alongside object-skip and area levelling, so the printer compensates for any surface variation before a single line of filament is laid down. Pressure advance and flow calibration fine-tune extrusion in real time, keeping walls clean and corners sharp across the full build volume.

AI monitoring that keeps long prints on track

Unattended overnight prints carry real risk — but the Kobra S1 Max watches over your work so you don’t have to. An onboard AI spaghetti detection system flags failed prints before they waste hours of filament. Filament runout detection, filament entanglement detection, and automatic resume mean a snapped or tangled spool won’t ruin a job. Power-loss resume picks up exactly where the printer left off if the power cuts out, and the standard HD camera (720P) lets you check in remotely via the Anycubic App.
