The Technology
In contrast to synthetic materials, materials produced by organisms are formed in ambient conditions and with a limited selection of elements. Nevertheless, living organisms reveal elegant strategies for achieving specific functions, ranging from skeletal support to mastication, from sensors and defensive tools to optical function.
Compressive stress is used to achieve enhanced mechanical properties of ceramics. The known processes require high temperatures and pressure, and the effect might relax over time after cooling. Toughening the otherwise brittle calcite using bio-inspired strategy for pre-stressing ceramics without heating, high pressure and quenching was achieved using natural process, which employs coherent nano-precipitates to induce compressive stresses on the host matrix.
The method can be applied to 3D printed amorphous materials as well as other processes
