| Abstract Scope |
Additive Manufacturing (AM) of ceramics is a timely topic because it allows to produce customized functional ceramic parts with geometrical complexity. Currently, AM is achieved most commonly through multistep “indirect” processes requiring supplementary steps, such as debinding and sintering. Among indirect processes, Direct Ink Writing (DIW) allows 3D structures to be built layer-by-layer through the deposition of concentrated ceramic slurries. An example of DIW of doped β-TCP scaffolds for bone tissue engineering is presented here highlighting its limitations. Indeed, despite being attractive to produce macroporous scaffolds for bone regeneration, DIW still requires post-treatment steps to obtain functional parts.
In order to develop an alternative direct AM process, the Losego group (Georgia Tech) is studying an innovative pathway for AM of ceramic parts combining inorganic binders with photonic curing. This approach can find promising applications in the bioceramics field due to its applicability to a wide range of materials. |
