Abstract

Highlights A novel method combining digital light processing 3D printing with suitable sintering processes to fabricate complex structures of multiscale porous titanium scaffolds was proposed, and new insights were provided for 3D printing of metals that are difficult to print by direct melting. Titanium powders were modified with an acrylic coating, improving the curing characteristics and the stability of titanium-based slurries for the fabrication of green scaffolds via digital light processing 3D printing. Green scaffolds printed with slurries using high solid loadings exhibited slight shrinkage after sintering, and the ease of control contributed to the preservation of the morphology of the structures.
