Abstract :Algae bioprinting offers an innovative solution for bioremediation by enabling the creation of functional 3D scaffolds. This study investigates the optimization of hydrogel compositions for 3D bioprinting Chlorella Pyrenoidosa, focusing on rheological properties such as viscosity to ensure printability and structural integrity [1, 2]. The optimized hydrogel formulation was determined by utilizing alginate (ALG) and carboxymethyl cellulose (CMC) with calcium chloride as a crosslinker. Printed scaffolds were assessed for efficacy in removing Congo red dye and utilized as a model contaminant. The findings indicate that the ideal hydrogel formulation improved structural integrity, nutrient diffusion, and pollutant removal efficacy. By day 7, the bioprinted constructs achieved a dye removal efficiency surpassing 95%, significantly exceeding the performance of free algae systems. This study paves the way for sustainable bioprinting technologies in environmental remediation.
