A 3D-printing support medium is provided herein, comprising hybrid calcium-alginate hydrogel particles and a dispersion medium, formulated by combining calcium-alginate and a soluble polymer distinct from alginate, and the dispersion medium contains a minimum of 2 mM gluconate. These hybrid hydrogel particles possess an average size ranging from 0.1 pm to 50 pm, with exceptional homogeneity characterized by a particle size distribution of less than 50% RSD, resulting in a substantially transparent medium to visible light. The support medium is provided in various forms, including drained particles and slurries with different volume ratios of hydrogel particles to the dispersion medium. The process of preparing this support medium involves forming, pulverizing, washing, and contacting the hybrid hydrogel particles with a gluconate solution, ensuring the presence of gluconate within the hydrogel matrix.
