In this study, using a new polymer combination of Chitosan(CH)/Xanthan Gum(XG) has been exhibited for wound dressing implementation by the 3D-Printing method, which was fabricated due to its biocompatible, biodegradable, improved mechanical strength, low degradation rate, and hydrophilic nature to develop cell-mimicking, cell adhesion, proliferation, and differentiation. Different concentrations of XG were added to the CH solution as 0.25, 0.50, 0.75, 1, and 2 wt% respectively in the formic acid/distilled water (1.5:8.5) solution and rheologically characterized to evaluate their printability. The results demonstrated that high mechanical strength, hydrophilic properties, and slow degradation rate were observed with the presence and increment of XG concentration within the 3D-Printed patches. Moreover, in vitro cell culture research was conducted by seeding NIH 3T3 fibroblast cells on the patches, proving the cell proliferation rate, viability, and adhesion. Finally, 1% XG and 4% CH containing 3D-Printed patches were great potential for wound dressing applications.
