Dual Extrusion
Two print heads. One machine. Unlimited potential.
IDEX (Independent Dual Extrusion) is a 3D printing technology where two print heads operate independently, enabling multi-material printing, duplication, and mirror production — significantly improving productivity and print quality.

Technology Overview
What is IDEX 3D Printing? Dual Heads. Independent Motion.
Idex (Independent Dual Extrusion) Enables Two Fully Independent Toolheads — Unlocking Parallel
Printing, Multi-material Capability, And Zero Contamination Workflows.
IDEX stands for Independent Dual Extrusion System — a unique 3D printer architecture.
In IDEX 3D printing, multiple parts can be produced simultaneously through the deposition of molten thermoplastic material.
Unlike conventional dual extrusion where both nozzles share one carriage, each IDEX head parks in its own dedicated position — preventing oozing, stringing, and material contamination.
This technology unlocks a wide range of applications across industries.
IDEX Technology
Four Operational
Configurations
IDEX printers support four distinct print modes — giving full flexibility to switch between redundancy, speed, symmetry, and multi-material workflows within a single machine.
// MODE 01
Duplicate / Twin Mode
Duplication mode enables the extruder to copy and replicate the master model. The second extruder
mimics the main extruder's movements and slicing parameters, building a synchronized copy in
parallel — printing two identical objects simultaneously. This doubles productivity and ensures
efficient, faster 3D printing with high precision.
// MODE 02
Mirror / Symmetric Mode
Mirror mode lets the extruder replicate the master model as a mirrored version. The second extruder
mimics the main one's movements and slicing parameters in parallel, creating a perfect symmetrical
copy — ideal for brackets, enclosures, and symmetrical assemblies. This boosts efficiency by
producing both halves at the same time.
// MODE 03
Dual Material / Dual Color
Print a part with two colors to enhance vibrancy and appeal. For complex prints, one hotend uses the
main material while the other uses hydro-soluble support material. After printing, the soluble
material dissolves in a solvent — leaving the final object with intricate details, smooth surfaces,
and perfectly clean finishes impossible with a single-head printer.
// MODE 04
Auto / Stand-Alone Mode
Slice any model and get it done with a hassle-free workflow using at least one active tool head.
Auto or Stand-alone mode lets you choose either the left or right extruder for your prints with the
required material and color — even in the case of breakdown of the other extruder, production
continues uninterrupted.
Engineering
System Architecture
IDEX is an advanced level of FFF 3D printing that allows two print heads to move independently from each other. Each head has its own hot end and carriage — capable of producing two prints at a single point in time, with two independent extruders creating multi-color and multi-material modes.
Dual Independent X-Carriage
Two extruders, each equipped with its own hot end, are mounted on independent X-carriages — achieving two individual X movements capable of producing two prints simultaneously without mechanical interference.
Parking & Wiping Mechanism
When one nozzle is active and printing, the inactive nozzle moves to a dedicated parking location with a wiping mechanism — ensuring clean, contamination-free prints with zero oozing or stringing on the final part.
Independent Temperature Control
Independent dual extruders allow the two nozzles to maintain a significant temperature difference from each other — enabling the combination of different materials including soluble support material with the core material for complex geometries.
Multi-Color & Multi-Material Modes
Two extruders accompany each other creating multi-color and multi-material modes including soluble support material — opening up complex designs beyond what a single head extrusion 3D printer can provide in a smooth, uninterrupted workflow.
Advantages
Why IDEX Outperforms
Combining IDEX with Duplication or Mirror mode effectively doubles productivity and cuts lead time by half — making this the most cost-effective and fastest solution for low-volume batch production.
— 001
DOUBLE THE PRODUCTIVITY (2×)
With Duplicate mode, the IDEX system allows printing two identical parts simultaneously — doubling production speed and halving lead time. The software automatically copies the selected part for hassle-free workflow, increased productivity, and reduced costs.
— 002
REDUCE LEAD TIME BY HALF
By printing two parts in parallel — duplicate or mirror — IDEX halves the cost and lead time compared to a conventional single-head printer. Production-ready batch runs that previously took a full day complete in half the time.
— 003
ZERO OOZING & STRINGING
The inactive nozzle moves to a parking location with a wiping mechanism — ensuring clean, contamination-free prints. Conventional dual extrusion with a shared carriage leaves the inactive nozzle in contact with the part, causing persistent oozing and stringing defects.
— 004
MULTI-MATERIAL PRINTING
Independent dual extruders allow the two nozzles to have a significant temperature difference — enabling the combination of different materials. Complex prints can use soluble support material alongside the main core material, opening design possibilities beyond any single-head system.
— 005
INCREASE EASE OF MULTI-COLOR USE
Print parts in two colors in a single run — enhancing vibrancy, appeal, and visual differentiation of prototypes and production parts. No post-processing or assembly of separate colored parts required.
— 006
UNIQUE CAPABILITIES: DUAL, DUPLICATE, MIRROR
IDEX unlocks four print modes unavailable on standard printers: Stand-Alone for redundancy, Dual Color for multi-material output, Duplicate for 2× batch production, and Mirror for simultaneous symmetrical part production.
