3D bioprinting for Rhinoplasty. A (i) 3D digital models of square blocks, human noses and cylindrical shapes after importing Slic3r and 3D bioprinting products, (ii) Detection of chondrocyte activity after 3 days of culture by live/dead with 20G and 22G needles, (iii) Alterations in the macroscopic structure of freeform reversible embedding of suspended hydrogel bioprinting constructs before culture and after 6 weeks of culture [192]. B (i) Macrostructure of GelMA/chondrocyte print products based on day 0 and day 50 with calcein AM staining of cell fluorescence images (ii) Day 50, cell distribution of frozen sections using DPI staining showing GelMA/chondrocyte structure [196].
