Sedimentation characteristics of bioinks containing 10% w/v CAM of different particle sizes at 37 °C observed under stereomicroscope. A) GelMA group as control, B) 0–150 µm group remained almost homogeneous after 1 and 3 h, and the layer phenomenon was observed in C) 150–300 µm and D) >300 µm groups after 1 and 3 h. E) The sedimentation distances of the three groups with different particle sizes. The results showed that the settlement became more obvious with the increasing of the CAM particle size (**p < 0.01, ***p < 0.001, ****p < 0.0001).
