Abstract

A new self-setting ceramic ink was developed for robocasting of biomimetic hydroxyapatite scaffolds, based on alpha-tricalcium phosphate and gelatine. After setting a biomimetic hydroxyapatite is obtained, with higher reactivity and resorbability than high-temperature sintered hydroxyapatite. The setting reaction of the ink results in a significant increase of the mechanical properties of the scaffolds.
