Fig. 3

a 3D plot of mean core diameter in function of nozzle diameter and rpm presented by filled markers, with size indicating magnitude. b 3D plot of mean shell thickness as a function of nozzle diameter and rpm; error bars denote standard deviation, and the color scale highlights variations in core dimensions. c Histograms showing the particle distribution produced with nozzle diameters of 340 µm, 410 µm, and 480 µm at rotational speeds of 100, 1500, 2000, and 2500 rpm. The sample size for each histogram varies from 50 to 90 microspheres. All histograms were plotted with a bin width of 50 µm. (i) Combined histograms for core diameter. (ii) Combined histograms for shell thickness. \({D}_{{Nozzle}}\) = 410 µm and 480 µm at 3000 rpm resulted in fiber formation, and \({D}_{{Nozzle}}\) = 340 µm at the same rpm resulted in non-spherical samples, these cases were excluded from the analysis
