Description

Designed to make high-speed 3D printing both accessible and dependable, the Anycubic Kobra S1 combines advanced automation with precision engineering. Its fully enclosed CoreXY construction improves print stability while allowing reliable printing with temperature-sensitive materials such as ABS and ASA. Smart functions including AI Spaghetti Detection, automatic bed leveling, filament monitoring, and power loss recovery help reduce failed prints, while the integrated HD camera allows remote monitoring over Wi-Fi. Part Number KBS1BK0C-O delivers an excellent balance of speed, print quality, quiet operation, and material compatibility for demanding everyday use.

Features

Built for Fast, Accurate Printing
The CoreXY mechanical design minimizes moving mass, allowing the printer to maintain excellent accuracy even at higher speeds. Linear rod motion on both the X and Y axes provides smooth travel, while the three-guide-pole Z-axis enhances stability throughout taller prints.

Key performance highlights include:

• 250 x 250 x 250mm enclosed build volume
• Recommended print speed of 300 mm/s
• Maximum print speed up to 600 mm/s
• Recommended acceleration of 10,000 mm/s2
• Maximum acceleration up to 20,000 mm/s2
• Pressure Advance and Flow Calibration for improved print consistency

Supports a Wide Range of Filaments
With a powerful 320 degrees C hotend and heated PEI spring steel build plate, the Kobra S1 handles many of today's most popular materials without requiring hardware upgrades.

Compatible materials include:

• PLA
• PETG
• TPU
• ABS
• ASA

The standard 0.4mm nozzle is suitable for everyday printing, while optional 0.6mm and 0.8mm nozzles provide flexibility for faster production or larger models.

Intelligent Print Protection
Built-in automation helps protect long print jobs and minimizes wasted material by detecting common printing problems before they become expensive failures.

Smart monitoring functions include:

• AI Spaghetti Detection
• Filament runout detection
• Filament entanglement detection
• Power loss recovery
• LeviQ 3.0 automatic bed leveling
• Automatic Z-Offset adjustment
• Object Skip and Area Leveling

An integrated HD camera supports remote 480P video monitoring through the Anycubic App over Wi-Fi, allowing users to check print progress from virtually anywhere.

Quiet and Easy to Operate
Despite its high-speed performance, the Anycubic Kobra S1 operates remarkably quietly, making it suitable for home offices, workshops, classrooms, and shared workspaces.

User-friendly control options include:

• Responsive 4.3-inch capacitive touchscreen
• USB printing
• Wi-Fi connectivity
• Anycubic App support
• Kobra OS firmware
• Support for nine interface languages

Quiet mode can reduce operating noise to as little as 44dB, making overnight printing far less disruptive.
