D printing of viscoelastic materials with poor rheological properties is
impossible in atmospheric conditions. Indeed, a significant yield stress
character of the material is required to maintain the shape of the 3D object after
deposition. This character might be achieved through material re-formulation but
in the case of particular application such as biomedical implants, modification of
rheological properties through change in material composition is excluded and
alternative solutions must be found. The use of supporting gel systems can be
proposed as an elegant solution to maintain the 3D object shape during printing
and solidification. Nevertheless, the supporting gel systems are not perfect and
some problems rise such as material bearing, poor layer cohesion and low gel
self-healing. Rheological characterizations focused on hardness, yield stress and
thixotropy measurements are then the best way to understand and predict the
performance of the system. Thus, for each printing material intrinsic properties
and solidification conditions, an adequate gel formulation must be defined to
successfully obtain 3D printed objects. Hence, we propose an overview of this
technique through different applications using a multi-state and muti-scale
approach based on the correlation between rheological characterization and
3D printing observation. Our studies also come up with the use of biomaterial
including living cells in supporting gel systems. In this case, the gel must have an
additional function to assist cells maturation. Clear experimental results will be
presented together with different cases studies of highly challenging 3D printing,
demonstrating the superiority of the approach.
