State of the art and future direction of additive manufactured scaffolds-based bone tissue engineering

Purpose - This paper aims to review the advances in additive manufactured (AM) scaffolds for bone tissue engineering (TE). A discussion on the state of the art and future trends of bone TE scaffolds have been done in terms of design, material and different AM technologies. Design/methodology/approach - Different structural features and materials used for bone TE scaffolds are evaluated along with the discussion on the potential and limitations of different AM scaffolds. The latest research to improve the biocompatibility of the AM scaffolds is also discussed. Findings - The discussion gives a clear understanding on the recent research trend in bone TE AM scaffolds. Originality/value - The information available here would be useful for the researchers working on AM scaffolds to get a quick overview on the recent research trends and/or future direction to work on AM bone TE scaffolds.
