Orthopaedic surgery lends itself well to advances in technology. An area of interest and ongoing
research is that of the production of scaffolds for use in trauma and elective surgery. 3D printing
provides unprecedented accuracy in terms of micro- and macro-structure and geometry for scaffold production.
It can also be utilised to construct scaffolds of a variety of different materials and more recently
has allowed for the construction of bio-implants which recapitulate bone and cartilage tissue. This review
seeks to look at the various methods of 3DP, the materials used, elements of functionality and design,
as well as modifications to increase the biomechanics and bioactivity of 3DP scaffolds.
Keywords: 3D printing, Rapid prototyping, bone scaffold, orthopaedic implant.
