“…Wide range of printable biomaterials and inexpensive equipment are among extrusion bioprinting advantages. Many researchers have simply modified conventional commercial 3D printers to print biomaterials or developed their printing machines in-house to reduce the costs [2] , [24] , [29] , [31] , [33] , [34] , [35] , [38] , [41] , [42] , [43] , [49] , [55] , [56] . On the other hand, due to the need for development of bioprinters, commercial bioprinters have become widely available and employed by researchers [5] , [23] , [27] , [37] , [44] , [45] , [46] , [51] , [52] , [53] , [54] , focusing on enhancing the printing quality and suitability for printing wider range of biomaterials.…”
