Based on our past episode about analysis methods used in material extrusion (ME), we are going to talk about the relevant parameters for production of the filament used in ME today.
This week’s topic:
Rheological properties impact at all stages of material use across multiple industries – from formulation development and stability to processing and product performance. The type of rheometer required for measuring these properties is often dependent on the relevant shear rates and timescales along with sample size and viscosity. For polymers, two different types of rheometers are available. If we want to study higher shear rates, the capillary rheometer is the best device to use.
- Viscosity flow curves
- How filament for material extrusion is produced
- How to use the capillary rheometry to analyze viscosity during filament extrusion and which effect temperature settings have on viscosity
