In our last episode, we talked about the basics of viscosity and rheological measurements with the capillary rheometer for filament production. Today, Dr. Natalie Rudolph will correlate the results that are relevant for the filament extrusion to the melt rheology inside the material extrusion head using the same capillary rheometer.
This week’s topic:
Learn today, how to calculate the shear rates that occur in your material extrusion process, what the relevant viscosity flow curves look like and how to use them to determine the ideal print temperature.
- Shear rates in the additive manufacturing technology material extrusion
- Viscosity of ABS filament at the nozzle tip
- Effects on viscosity when increasing processing temperature or adding fillers and additives
