Creality showcased its K2 Plus on its 10th Anniversary & Spring event on April 9th, 2024. Creality K2 Plus is a 350*350*350mm large print size CoreXY 3D printer, an addition to Creality's K series lineup. It also comes along the release of Creality CFS, which supports multicolor prints up to 16 colors.

CFS - Creality Filament System

The K2 Plus multicolor printer will be sold in a combo kit along with the CFS. The CFS (Creality Filament System) enables up to 16 multicolor printing simultaneously by connecting four parallel units. With automatic filament loading and replacement, users can easily install filament into the CFS, which manages the entire process, including switching to an equivalent filament if needed.

Utilizing RFID technology, the CFS intelligently identifies the type, color, and weight of the filament, selecting the most suitable one for the print. For non-RFID filaments, manual entry and customization of filament details are straightforward. The CFS serves as an intelligent filament management system, streamlining 3D printing and simplifying filament handling.

Its fully sealed design, along with a screen displaying temperature and humidity, ensures optimal printing conditions. Innovative features such as a spring-loaded stabilizer and filament buffer prevent filament escape and enhance printing reliability.

CFS Compatibility

Creality announced in the anniversary live that the CFS is designed to be compatible not only with the K2 plus, but also with other 3D printers that they plan to release in the future. And for those who already own Creality K1, K1 Max, K1C, or Ender 3 V3 printers, upgrade kits will be available. These kits will enable users to integrate the multicolor system into their existing printers, expanding their capabilities.

Multicolor printing not only enhances the visual appeal of prints but also improves efficiency, allowing designers to showcase intricate details more vividly to customers.

Water-Soluble Supports

The CFS also facilitates support removal, offering option of water-soluble supports, making post-processing easier and more efficient. With these capabilities, multicolor printing with the CFS opens up new possibilities for creative expression and design innovation.

Max Speed 600mm/s, Max Acceleration 30,000mm/s²

K2 Plus can reach a blazing 600mm/s with an acceleration of 30,000mm/s². This means a standard benchy can be completed in just 10 minutes. Some may question why the K2 Plus is faster than the K1 and K1 Max, which can also reach speeds of 600mm/s. The key lies in the acceleration speed. The printer undergoes deceleration, directional change, and acceleration between the small segments of the printing path, which consumes significant time. Therefore, despite maintaining a uniform speed, the K2 Plus can substantially reduce the overall print time.

ABS-CF Printing Tip

Like all ABS, ABS CF must be kept dry! If it does not remain packaged with desiccant, it will readily absorb moisture from the air; this will lead to degraded print quality and wasted filament. You can dry it out by using a filament dryer for more precise dehydration for all filament types.
