![]() The novel V-zigzag toolpath design required deposition at varying printing speed along the path, to create the zigzag structure with variable width (200% of nozzle diameter) at pre-determined locations. For each design, a single layer of filament was deposited as the nozzle moved in the X or Y direction, while simultaneously controlling the extrusion volume and printing speed to achieve seamless Y- or cross-junction channels. A range of complex geometries and channel widths (100–400 µm) were developed by direct GCode scripting including passive mixers of hexagonal, diamond, zigzag and variable-width zigzag (V-zigzag) and hydrodynamic flow focusing components. ![]() This study is the first to report the fabrication of complex microfluidic devices based on CONtinuously Varied EXtrusion (CONVEX) of extruded filament in material extrusion additive manufacturing (MEAM).
