Creality K3 and SPARKX i8: Two Approaches to Multicolor Printing

1 min read

The Chinese manufacturer is targeting reduced waste and downtime with different material-switching architectures.

K3: nozzle switching

The K3 KliTek system switches nozzles; Creality claims 4.8-second changes and substantial waste reduction. Independent long-term testing is still needed.

SPARKX i8: short material path

The i8 feeds four filaments into a shared hotend, aiming to reduce long retractions and purge cycles.

Video reference

The related ShareFest hands-on video shows the K3 mechanism up close but does not replace long-term performance testing.

Anycubic Kobra 3 toolhead – successful firmware backup and the first steps toward a CAN-based Klipper toolboard

Anycubic Kobra 3 Toolhead Project – Another Milestone: Successful Firmware Backup and Preparing for a CAN-Based Toolboard Today marked another major milestone in the Anycubic Kobra 3 Toolhead project. Our objective is not to modify or preserve the original firmware. Instead, we are developing a completely custom firmware that will transform the factory controller board into a Klipper-compatible CAN Tool MCU with only minimal hardware modifications.
