Creality Announces SPARKX i8 Multi-Colour Printer via Crowdfunding

Creality has launched an Indiegogo crowdfunding campaign for its latest desktop machine, the SPARKX i8. The new multi-colour fused deposition modelling 3D printer routes four separate filament channels through a single toolhead, introducing specific engineering approaches aimed at cutting down transition times and purge material waste.

The QuarTeks Color Change System

At the core of the i8 is Creality’s QuarTeks Color Change System. Instead of swapping individual toolheads or relying on external multi-material boxes, four independent filament lines feed directly into a single printhead. According to the manufacturer, the shared filament path near the nozzle tip measures under one millimetre in length with a volume of approximately two cubic millimetres.

Creality states that keeping this shared channel exceptionally short allows the printer to complete a colour switch in under one second. The mechanism functions similarly to a multi-coloured ballpoint pen, reducing the retraction, feeding, and purging lengths required between swaps. In laboratory testing highlighted by the company, a model featuring 3,000 colour switches was completed in roughly 18 hours.

Waste Reduction and Layered Mixing

Multi-colour desktop printing typically generates substantial waste through purge towers and material flushes. The i8 attempts to address this by routing transition waste directly into a model’s internal infill or inner walls when using appropriate slicer settings. Creality claims this approach brings external purge waste down to zero grams, while a dedicated clean wall helps isolate infill colours to maintain surface cleanliness.

Additionally, the printer supports what the manufacturer calls CMYK layered colour mixing. By varying layer thickness and the mixing sequence across four base filaments, the machine blends intermediate tones, gradients, and brightness shifts. Creality notes this technique can produce between 16 and 32 colour combinations from four base spools, though it stresses that layered mixing is not a substitute for precise colour matching.

Sensors and Automation

The printhead integrates 13 sensors alongside an AI vision camera to monitor the filament channels, switching actions, and overall print status in real time. These sensors are designed to detect empty spools, runouts, and air printing. The machine also includes an automatic refill function, allowing users to load up to four spools of the same material and automatically switch to a fresh spool when the active one empties.

What This Means for South African Makers

Multi-colour desktop 3D printing has largely been dominated by external multi-material hub systems that increase desk footprint and purging waste. The introduction of single-toolhead, multi-channel designs highlights a broader industry shift toward faster filament switching and reduced material consumption. For local hobbyists, design studios, and small print farms, minimizing purge waste reduces the cost per print and shortens production times for multi-colour functional prototypes and models. However, because the machine is currently launched through crowdfunding, prospective local buyers must weigh the usual international shipping timelines, import duties, and warranty logistics before committing funds.

DC3D’s Take

Creality’s focus on shortening the transition path inside a single toolhead is a practical step toward solving one of multi-material printing’s most persistent drawbacks: wasted filament and lengthy transition times. While manufacturer claims regarding zero external purge waste rely heavily on optimal slicing configurations and model geometry, the hardware concept is promising. We will be watching to see how the QuarTeks system performs in independent user hands once production units land and real-world testing validates the speed and reliability of those frequent colour switches.
