a Optical microscopic image of embedded 3D printing. b Filament diameter changes over time with nozzle diameters of 10 and 5 µm. c Illustration of printing straight filament in a gel. d Optical microscopic images of printed filaments and (e) their diameter depending on the yield stress of the gel with 1 and 48 Pa and printing speed from 0.1 to 1.0 mm/s. f Illustration of printing 90° curved filament in a gel. g Photographs of printed 90° curved filaments and (h) their accuracy parameter Δp depending on the yield stress of the gel from 1 and 48 Pa and printing speed from 0.4 to 1.0 mm/s. i Coils printed at different high speeds. Images of (j) a manifold for extruding through 9 nozzles and (k) printed 3D features.
