Abstract

The human face is highly individualised enabling us to distinguish one human being from another. Consequently, if disfigured the patient often suffers from severe psychosocial effects and strongly desires a functional and aesthetic restoration. However, current practice of facial reconstruction is frequently below the patients expectations [1]. This could be improved by 3D printing of artificial bone scaffolds personalised to the patient. This process requires a liquid binder to stick together ceramic powder one layer at a time. In this study the mechanical properties of hydroxyapatite (HA) discs using sodium trisilicate solution (STS) and malic acid with chitosan (MAC) as binders are investigated.
