The battle of dual-extruder technologies
Dual-extruder systems are popular because they enable multi-material printing and soluble supports. But not all dual-extruder technologies are equal. Raise3D’s RMF500 uses independent dual extrusion (IDEX), while DivByZ machines use dual servo extruders. Choosing the wrong system can mean more downtime and maintenance.
Understanding the difference
A Dual IDEX system contains two independent print heads that move separately. They excel at printing duplicate parts or combining different materials but introduce mechanical complexity. When one extruder jams, printing pauses for manual intervention and spare parts can be costly.
DivByZ’s Dual Servo Extruder, by contrast, feeds a single nozzle with two servo-controlled units. If one unit runs out of filament or needs maintenance, the other takes over seamlessly without pausing the print. This design reduces moving parts and simplifies calibration.
Why DivByZ’s approach boosts productivity
- Reliability – The anti-clog system continuously monitors filament flow and clears obstructions, ensuring consistent extrusion.
- Continuous printing – DivByZ customers report printing for over 20 days without intervention, eliminating downtime.
- Reduced maintenance – Fewer moving parts mean less calibration and fewer mechanical failures. Operators spend more time designing and less time fixing jams.
- Case study – Bangalore tooling supplier – A tooling supplier switched from an IDEX printer to DivByZ’s Aion 500 MK2. Jams and manual swaps used to cause delays; after adopting the servo extruder, they printed for weeks with no interruptions and noticed increased output and less operator fatigue.
Competing guides from Stratasys and BigRep highlight speed and size but largely ignore reliability. DivByZ’s patented combination of anti-clog plus auto-switchover addresses the everyday pain that others overlook.
