Freeze-printing of pectin/alginate scaffolds with high resolution, overhang structures and interconnected porous network

Additive Manufacturing 2021 Volume 46, Article 102120

We report herein the fabrication of a pectin-based scaffold (6 wt% pectin, 3 wt% alginate) with high resolution (small-diameter rods), small pores, and interconnected porosity using a low temperature 3D printing process known as freeze-printing. The ability to successfully print natural polymers has been a long-standing challenge in the field of additive manufacturing of polymeric tissue scaffolds. This is due to the slow evaporation rate of the aqueous solvent, which leads to unstable structures. This problem has been addressed by utilizing the fast solidification rate of the freeze-printing process. Scaffolds with a hgresolution (rod-diameter of 83 ± 14 µm), small…
