High-flow extrusion systems.
Increasing material throughput while maintaining process control.
Development of high-performance polymer extrusion systems for substantially higher material flow rates, with a focus on thermal performance, extrusion force, flow stability and repeatable deposition.
Project overview
High throughput is a complete process-engineering problem.
The project has progressed beyond initial concept design into active prototype development and experimental characterisation.
MYCNC3D is developing high-performance polymer extrusion systems intended to substantially increase material throughput while maintaining control over thermal behaviour, extrusion force, flow stability and deposition quality.
The research considers high-flow extrusion as a complete process-engineering problem. Increasing heater power or nozzle diameter alone is not sufficient: melting capacity, polymer residence time, extrusion mechanics, temperature stability and sustained material flow must operate together within a controlled process window.
Current work focuses on refining the extrusion architecture, instrumenting the process and establishing repeatable operating conditions.
The objective is not simply to achieve a high peak flow value, but to maintain elevated material throughput in a stable, measurable and repeatable manner.
Why it matters
Productivity without losing process control.
Material throughput is one of the principal limitations affecting FDM productivity. Increasing achievable flow can reduce manufacturing time, enable larger deposition geometries and make polymer extrusion more relevant for larger-scale and industrial applications.
Higher flow also increases the importance of melt quality, temperature stability, extrusion force and thermal management. MYCNC3D therefore treats extrusion performance as a process-control problem rather than a single maximum-flow metric.
Current focus
What we are characterising now.
Melting capacity
Relationships between extrusion geometry, residence time, polymer temperature and achievable throughput.
Extrusion force
Mechanical force required to transport filament through the system under different operating conditions.
Flow stability
Sustained material flow, pressure behaviour and consistency over time rather than short-duration peak values.
Deposition quality
Conversion of higher flow into stable and usable deposition without unacceptable loss of process control.
Instrumentation & validation
Instrumented test methods for comparing architectures and identifying thermal, mechanical and flow limitations.
Engineering approach
Prototype. Measure. Iterate.
MYCNC3D develops the extrusion system through iterative prototyping and instrumented testing. Design changes are evaluated through measurable parameters such as material flow, extrusion force, temperature stability and deposition behaviour.
This approach progressively establishes the operating envelope of each extrusion architecture and connects extrusion performance with the broader MYCNC3D manufacturing platform.
Current status
UNDER DEVELOPMENT
The project is in active prototype development and experimental characterisation. Current work focuses on refining the extrusion architecture, instrumenting the process and establishing repeatable operating conditions.
The system remains a research and development platform and is not currently presented as a commercial production product.
Next milestone
Structured performance validation.
The next milestone is to establish a repeatable validation methodology covering sustained material flow, thermal stability, extrusion force and deposition quality across representative operating conditions.
Progress toward VALIDATION will require repeatable results, sustained rather than short-duration peak performance, controlled thermal behaviour and a clear correlation between measured extrusion conditions and resulting deposition quality.
Integrated platform
One pillar of a broader manufacturing system.
Multi-axis motion→High-flow extrusion→Advanced toolpaths
The long-term objective is to integrate material deposition performance with machine motion and manufacturing software rather than developing each technology independently.
