The numerical simulation of flows of highly elastic fluids has been the subject of intense research over the past decades with important industrial applications. Therefore, many efforts have been made to improve the ...

This research was focused on developing a method to control the width of extruded filaments, to have a controlled structure of the infills of 3D printed products manufactured by Fused Filament Fabrication (FFF). Different ...

Water addition is required for proper extrusion, improving dough flow, starch hydration and swelling, viscosity generation, and extrudate cellular formation. The implications of changing in-barrel moisture, however, is ...
