The K2 is good. Very good. What’s better? The K2 PRO.

• Name:K2 Pro. Because it’s more Pro than K2. Let’s figure out why (an NO, we’re not using AI-generated copy. This is all human written, baby!).
• Size: 300 x 300 x 300mm vs the K2’s 260 x 260 x 260mm. More volume = more better!
• Internal Storage: Up from 8GB to 32GB storage. That’s a huge amount of space. Probably more handy for storing time-lapse movies.
• Dual Cameras: One chamber monitoring camera, and on-head calibration camera. What’s different is the nozzle camera can perform automatic flow rate calibration.
• RFID Spool Detection: For single-spool operation, there’s an NFC reader ready to auto-read your spool’s RFID data.

What’s the same? Pretty much these following K2 traits:

• CFS out-of-the-box: Matches the K2. No difference there.
• Motion Control: 3-phase AC “Field Orientation Control” motors are the same, still featuring superior speed and precision than stepper motors.
• Hotend temperature: 300°C – hot enough for most filaments
• Nozzle: It’s an enhanced version of the Unicorn tri-metal nozzle, which are also still quick-to-change.
• Active Chamber Temperature Control: A dedicated ventilation unit maintains a desired chamber temperature.
• Connectivity: USB thumbdrive and dual-band wifi 2.4 and 5GHz.
• Upgraded Z-Axis Motion System: Dual rail-pairs for vertical motion coupled with the new FOC motors make for rapid calibration and motion events.
• Smart Auto-Leveling: Rather than checking the level of the ENTIRE platform, the K2 does a selective level, only probing the area it’s going to use. MUCH quicker.

All the other features are common between them – size/speed/firmware/screen… it still very much feels like a regular K-series printer. This is a nice change of pace from Creality’s regular “Let’s totally change up the menu system again” design philosophy.

The new FOC motors allow acceleration up to an impressive 30m/s² – that’s three times as fast as the acceleration due to gravity! That means it can quickly get up to speed, then slow down again during a print, which is part of the reason it can print so fast. But to make use of this speed, make sure to run those calibration routines built into the printer!

Features:

• Ships practically fully assembled – remove a few shipping screws, run the automatic self-test and calibration routine, and you’re ready to print.
• Direct drive extruder rated to 300°C, capable of 40mm³/s of filament flow.
• Automatic bed leveling uses strain gauges for an accurate and consistent first layer.
• Monitor print progress locally using the built in web interface or from anywhere using the Creality Cloud application.
• CoreXY mechanical movement system driven by the CrealityOS (which is a fork of the ground-breaking Klipper firmware) allows for fast prints without sacrificing quality.
• Fully enclosed metal frame makes ABS and other hard to print materials possible (and useful for those owning cats!).
• Multiple part cooling fans – one on the hotend and another monstrous auxiliary part-cooling fan mounted inside the case, plus a chamber temperature control unit.
• Exhaust port Charcoal filter tray for fume mitigation.
• Light bar for illuminating your print progress.
• Load files over Wi-Fi or via USB thumb stick – no more fiddly micro SD cards!
• Removable complete top cover for thermal control and easy maintenance access.
• Removable PEI powder-coated spring-steel build platform.
