If you’ve ever lost a print to a jammed nozzle, you know the sinking feeling of wasted time and material. In large-format printing, a single clog can cost days and thousands of rupees. While competitors advertise dual extruders and multi-material capabilities, they rarely explain how they handle clogs or material switches.
DBZ engineers approached the problem differently. Instead of relying on standard hot-ends, we created a patented dual-servo extruder with auto-switchover and a smart anti-clog system. These innovations are designed to keep your prints running, even when other machines would stop.
How competitors compare
BigRep’s PEX2 extruders boast a 40% higher flow rate and the ability to print with dual extruders in Twin Mode. That’s impressive—but it doesn’t address what happens when one nozzle clogs. Likewise, the Anycubic Kobra Plus includes a filament run-out sensor and resume function, yet a clogged extruder still halts production.
To tackle this issue, DBZ’s dual-servo extruder design uses two independent servo-controlled filament feeds. If one feed encounters resistance, the system automatically switches to the second extruder while the first purges and recovers. Coupled with our anti-clog technology—which keeps nozzles clean and reduces downtime—this design ensures continuous printing even in demanding, long-duration jobs.
Benefits of DBZ’s dual-servo extruder
- Auto-Switchover Dual-Servo Extruder: The extruder senses any feed irregularity and seamlessly switches to the backup servo, maintaining print continuity and quality.
- Smart Anti-Clog System: Specially designed nozzles and active monitoring prevent material build-up and automatically purge to avoid blockages.
- High-speed Printing: Pairing dual-servo extruders with a moving gantry architecture allows fast and precise deposition, reducing project lead times.
- Real-time Alerts: Store up to 3000 G-codes on board and receive real-time updates on process status.
Our clients have seen dramatic reductions in downtime. Instead of babysitting printers or restarting failed jobs, their teams focus on design and innovation. For example, an automotive supplier recently ran our Aion 500 MK2 continuously for nearly three weeks—producing more than 50 full-scale jigs without a single nozzle jam.
