i+Med reviews the different types of bioprinting and coating technologies and the essential parameters operating the applicability of bioinks with an emphasis on hydroxyapatite as the active ingredient.

The use of biomimetic hydroxyapatite as the main active ingredient of 3D printed bioinks is of great benefit to enhance the bone tissue generating capacity of the cellular scaffolds of printed bone structures. Three-dimensional (3D) printed structures with multi-scale porosity are exciting manufacturing processes that offer biological and physical benefits and can potentially accelerate patient recovery.

Bioinks aim to reduce the limitations of commonly applied treatments by enhancing osteoinduction and osteoconduction, thus accelerating tissue regeneration or improving the integration of implants into tissues, among other advantages.
