- © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.The 3D bioprinting technique consists of obtaining three-dimensional structures of fibers stacked layer after layer, and this work presents the use of an alginate/gelatin hydrogel to print porous scaffolds. However, the bioprinting process requires a customized approach in the crosslinking stage, and that is why our work lies in the implementation of a support material that provides structural stability by using hydrophobic sands and calcium chloride (CaCl2). Showing results of the bioprinted hydrogel matrices within the support bath with 1.05% error with respect to the designed in the printing gcode.
