Creality QuarTeks™ vs KliTek™: Two Approaches to Multicolour 3D Printing

Modern multicolour 3D printing is about much more than adding another spool of filament. Every colour change affects print time, filament consumption, mechanical complexity and reliability — particularly when a model contains hundreds or thousands of switches.

Creality has developed two very different approaches to this challenge.

The SPARKX i8 uses QuarTeks™, an integrated four-channel system built around a single toolhead and nozzle. Its priority is rapid four-colour switching with minimal shared filament path and reduced transition waste.

KliTek™, developed for the Creality K3, takes another route. Instead of routing several materials through the same nozzle, it uses independent channels and interchangeable nozzle assemblies, enabling the system to extend from multicolour printing into multi-material, TPU and mixed-nozzle applications.

Understanding the difference between the two architectures helps explain why they are designed for different types of makers and different printing jobs.

QuarTeks™ vs KliTek™: Key Differences

The switching figures are not a direct like-for-like comparison. QuarTeks™ changes an internal filament channel while retaining the same nozzle. KliTek™ carries out a physical nozzle exchange, which enables capabilities that a shared-nozzle system is not designed to provide.

How Does QuarTeks™ Work?

QuarTeks™ keeps four filament channels inside the SPARKX i8 toolhead. Instead of withdrawing one filament through a long feed path and loading another from the spool, each colour remains close to the hotend.

An internal mechanism selects the required channel when the sliced model requests a colour change.

The design follows a similar principle to a four-colour pen: all available colours are already contained within one mechanism, ready to be selected without replacing the entire tool.

Sub-One-Second Colour Switching

Once one colour has finished printing, the system selects the next channel and feeds its filament through the very short common section near the nozzle.

Creality specifies a switching time of under one second.

Because the same toolhead remains in place, the printer also avoids repeated docking, pick-up and XYZ alignment operations. On a complex four-colour model, reducing the overhead of every individual switch can have a substantial effect on the final print time.

Why Is the Shared Filament Path So Short?

A conventional single-nozzle multicolour system usually needs to clear residual filament from a common path before the next colour can appear cleanly at the nozzle.

Longer shared paths require more transition material to be pushed out.

QuarTeks™ reduces this shared section to less than 1 mm. With much less residual filament around the changeover point, the system can minimise purging and reduce colour contamination.

For appropriate models and slicing strategies, some transition material can also be incorporated into the print rather than requiring a conventional purge tower.

Does QuarTeks™ Really Produce Zero Waste?

The wording needs some context.

SPARKX i8 has been demonstrated on models where no purge waste was generated during the actual printing process. However, a small amount of filament may still be flushed during initial preparation, and results depend on the specific model and slicing settings.

A more precise description is that QuarTeks™ is designed to eliminate external purge waste in suitable prints and dramatically reduce material used during colour transitions.

How Is KliTek™ Different?

KliTek™ is designed around a broader problem than colour alone.

Different parts of one printed object may require different mechanical properties. One region may need rigid filament, another flexible TPU, while a support interface may perform better with a different material entirely.

There is also no reason every part of a complex model must always be printed through the same nozzle diameter.

KliTek™ addresses these requirements by maintaining independent filament paths and changing compact nozzle assemblies when required.

A Nozzle Changer, Not a Conventional Multi-Head Printer

It is important to distinguish KliTek™ from a traditional multi-head tool changer.

Some tool-changing systems park and exchange a substantial section of the complete printhead. That can add mass, mechanical complexity and demanding docking requirements.

KliTek™ instead concentrates the change on a compact nozzle assembly while keeping the main motion system shared.

The K3's architecture uses four independent channels and four nozzles, with a specified nozzle-changing time of approximately 4.8 seconds and repeatability below 25 μm.

Why Independent Nozzles Matter for Materials

Physical separation becomes valuable when the materials being combined behave differently.

Rigid and Flexible Printing

A multi-material model could include a rigid structural section alongside a flexible feature, seal, hinge or contact surface.

Keeping extrusion paths independent avoids repeatedly pushing materials with very different flow properties through the same hotend.

Advanced TPU Workflows

KliTek™ is also designed around flexible-material printing, including workflows where different colours or material properties are used within the same TPU model.

This moves the technology beyond decorative multicolour printing towards functional parts in which material behaviour is part of the design.

Mixing Nozzle Diameters in One Print

Another important K3 capability is the use of different nozzle diameters within a single job.

Supported options include 0.2 mm, 0.4 mm, 0.6 mm and 0.8 mm.

A larger nozzle can process substantial internal areas and infill more efficiently, while a smaller nozzle can focus on fine lettering, exterior detail or small contours.

The goal is not to maximise the number of nozzle changes. Each switch has to justify its own overhead through a meaningful gain in print speed, material compatibility or detail.

How Do the Two Systems Reduce Filament Waste?

Both technologies attempt to reduce one of the biggest inefficiencies of conventional multicolour FFF printing: repeated purging.

QuarTeks™: Keep the Common Path as Short as Possible

• Four filament channels extend directly into the toolhead.
• The common path near the nozzle is less than 1 mm.
• Less residual filament needs to be displaced.
• Channel changes take place internally.

KliTek™: Keep the Material Paths Separate

• Each nozzle has an independent extrusion route.
• Different materials remain physically separated.
• Repeated unload-and-reload cycles through a common hotend are reduced.
• Nozzle diameter can change together with the printing task.

Put simply, QuarTeks™ reduces the shared path, while KliTek™ removes the need for one shared printing path in the first place.

When Does QuarTeks™ Make More Sense?

QuarTeks™ is designed around makers who mainly want fast and efficient four-colour printing without adding unnecessary mechanical complexity.

Typical projects include:

• figures and collectibles;
• decorative prints;
• toys;
• colour-coded models;
• visual prototypes;
• batch jobs containing frequent colour changes.

For these use cases, the single-toolhead architecture keeps the workflow relatively simple while reducing switching and purge overhead.

When Does KliTek™ Make More Sense?

KliTek™ becomes more relevant when a model requires more than different colours.

Potential applications include:

• functional prototyping;
• rigid and flexible material combinations;
• TPU printing;
• dedicated support materials;
• mixed nozzle diameters;
• engineering-material workflows;
• functional print-in-place assemblies.

QuarTeks™ is therefore primarily an optimisation of four-colour printing. KliTek™ expands the concept towards multi-material and multi-nozzle manufacturing.

Two Architectures, One Goal

QuarTeks™ and KliTek™ take different routes, but both address limitations that have traditionally made multicolour 3D printing slower and more wasteful than single-colour printing.

QuarTeks™ brings four colours almost all the way to one nozzle and makes switching between them extremely fast.

KliTek™ keeps nozzle and material paths independent, allowing the printer to change not only colour but also material properties and nozzle diameter.

The choice between these architectures therefore depends less on which technology is “better” and more on what the print itself needs.

For makers focused primarily on four-colour models, speed and filament efficiency are central. For users working with different materials, flexible filaments and nozzle diameters, physical separation provides a different kind of flexibility.
