Using bioprinting to pattern your alginate hydrogels is an innovative way to add complexity to your 3D cultures and develop novel applications using this biomaterial. All these techniques can be used for tissue engineering, vascularization, bioink development, and drug delivery.
In this white paper, we review unique methods for bioprinting sodium alginate using the Allevi 3 bioprinter, involving pre-crosslinking it with calcium chloride solution, coaxial printing of hollow tubes core-shell structures, and embedded printing with FRESH support.
