K2 Plus Combo 

A king-sized powerhouse that’s sturdy, practical, and designed for large-scale, high-performance printing

The K2 Plus Combo expands the K series into true large-format territory with a 350³ mm build volume — big enough to handle helmets, props, or batches of smaller parts in one go, all while delivering speed and precision.

New "Matrix" Frame, Ultra Sturdy
A. Reinforced Exoskeleton: Top, base, and side pieces are die-cast from aerospace-grade aluminum alloy for outstanding rigidity.
B. 5 mm Aluminum Alloy Heatbed: Thick and warp-resistant for long-lasting stability.
C. Precision Steel X-axis Rail: Machined steel rail ensures smooth, accurate movement with excellent durability.

Industrial-Grade Motion System
The K2 Plus is the first desktop 3D printer to adopt FOC closed-loop step-servo motors across the XYZ axes and extruder. Each of its five motors supports 32,768 microsteps per revolution, achieving pinpoint accuracy, rapid positioning, and ultra-smooth motion at up to 600 mm/s with acceleration of 30,000 mm/s².

Quiet Yet Powerful
Thanks to its step-servo system and dynamically balanced fans, the K2 Plus maintains a noise level of ≤45 dB at 300 mm/s — about as quiet as typing on a laptop.

Smarter Automation
Belt tensioning is fully automated with a built-in pressure sensor, eliminating the need for manual adjustment. An automated filament cutter trims material precisely at the nozzle, while the runout sensor gives ample warning when a spool is nearly empty, reducing waste and failed prints.

Advanced Extrusion System
A high-flow hotend with an 80W heater pushes up to 40 mm³/s at 280 °C. The tri-metal nozzle resists heat creep and clogging, while its quick-swap magnetic design makes maintenance fast and simple.

High-Quality Output Every Time
Dual auxiliary cooling fans double the part cooling airflow, locking in crisp details and clean edges before stringing or warping can occur.

Dual AI Cameras + 18 Sensors
A chamber-mounted AI camera monitors the print, while a toolhead camera fine-tunes flow rates and PA values automatically. Backed by 18 integrated sensors, the K2 Plus actively tracks extrusion, leveling, and motion systems to maintain consistent print success.

Independent Dual Z-Axis
Two motorized Z-screws automatically correct tilt. With strain-gauge probing on the toolhead, the printer generates an accurate mesh for flawless first layers across its entire 350³ mm bed.

Seamless Setup and Operation
The K2 Plus arrives pre-assembled with a quick-start boot-up guide that covers leveling, calibration, and system checks. With smart software and intuitive workflow, it’s ready to print right out of the box.
