ChromaKit: With this set, every 3D printer can use up to 20 different filaments in one go

The ChromaSet from Co Print, which is currently being funded on Kickstarter, is intended to retrofit 3D printers with the option of printing with multiple colors in a single pass. The manufacturer also wants to achieve the broadest possible compatibility with different printers. This also includes the various rail systems of 3D printers.

Depending on the specific 3D printer used, different devices are required. When using a printer based on Klipper, the CromaPad control console does not have to be used additionally. The ChromaPad then controls the CX-1 extruder, with ChromaScreen also providing particularly powerful, open-source software. It should even be possible to control up to eight printers simultaneously via the ChromaPad, which should also be relevant for commercial suppliers.

Basically, several filaments are used, and not only can they have different colors, but different types of material. Accordingly, the ChromaHead print head has a device for cutting the colored filaments, which is necessary when changing the filament.

Although the number of filaments is limited, it is extremely high: up to 20 filaments can be used at the same time, and sets for up to four or eight filaments are being offered as part of the crowdfunding campaign. On Kickstarter, the price of the KCM kit is currently around 333 euros, which is suitable for Klipper 3D printers. The ChromaSet with the control panel costs at least 429 euros - plus shipping in both cases. The usual financial risks for crowdfunding campaigns apply.
