Noztek Xcalibur Servo
750W Servo Power. 600°C Capability. Research Without Limits.
Overview
The Xcalibur Servo is a ground-up redesign of Noztek's proven extrusion platform — engineered for researchers and material scientists working at the boundaries of polymer processing.
A 750W closed-loop servo motor with 17-bit encoder feedback replaces conventional open-loop DC systems, delivering ±0.1% speed regulation that responds instantly to viscosity changes mid-process. Barrel temperatures reach 600°C, unlocking PEEK, PEI (Ultem), PBI blends, and experimental composites that no other desktop extruder can touch.
With a 5-litre stainless steel hopper, throughput up to 2 kg/hour, and real-time torque monitoring, the Xcalibur Servo bridges the gap between desktop convenience and industrial-grade capability.
Key Features
750W Servo Drive
Closed-loop RS485 servo with 20:1 planetary gearbox. 17-bit encoder delivers real-time position and velocity feedback for ±0.1% speed regulation — even as melt viscosity shifts mid-process.
600°C Processing
From PLA at 180°C to PBI blends at 550°C. 200°C of thermal headroom above PEEK processing temperatures means room to optimise without hitting hardware limits.
2 kg/hour Throughput
125% output increase over previous models. 10 metres per minute of filament production — fast enough for small-batch manufacturing, precise enough for single-spool R&D.
5-Litre Stainless Hopper
350% capacity increase enables 2+ hours of unattended operation. Full stainless steel construction for pharmaceutical, food-contact, and hygroscopic material handling.
Real-Time Torque Monitoring
Live torque and load data during extrusion. See blockages developing in the torque curve before the motor stalls — intervene early, protect your materials and your equipment.
Electromagnetic Brake
24V servo brake holds screw position on power-down. Zero residual ooze, zero material waste. The screw stops exactly where you leave it.
Throughput That Improves Outcomes
2 kg/hour output and 10 m/min filament speed aren't just about volume. For high-temperature semi-crystalline polymers like PEEK, processing time in the melt zone directly affects crystallinity and mechanical properties. The ability to control speed precisely — and run faster when conditions allow — means better material outcomes, not just higher output.
Built for Rigorous R&D
Stainless steel construction throughout. A precision planetary gearbox rated for sustained high-torque loads. Every component is selected for reliability under the thermal cycling, material abrasion, and continuous operation that serious research demands.
Command Centre: Xcalibur Servo Extrusion Control Hub
Complex extrusion, simplified. Full servo control from a single intuitive interface.
3-Step Workflow
Setup → Warmup → Run. Train operators in minutes, not days. Servo parameters are pre-configured for common materials.
Live Servo Dashboard
Real-time graphs for temperature, RPM, torque, and load across all zones. Monitor servo feedback and spot process drift before it affects your filament.
Precision Tuning
Adjust heater bands individually, set servo speed and torque limits, and configure custom process profiles — all from one screen.
Smart Alerts
Instant notifications when temperatures drift, torque spikes, or loads exceed thresholds. Protect your materials, your equipment, and your experiment.
One-Click Data Export
CSV exports of full process data for compliance reporting, R&D analysis, publication support, or process optimisation.
