Direct writing of polymers

Description: 

The ability to pattern functional materials in three dimensions has great potential to drive scientific and technological advances in the fields of chemistry, physics, biology, materials science, as well as emerging areas including photonics, microfluidics, printable electronics, microelectromechanical systems and biomaterials. Direct-write assembly allows one to design and rapidly fabricate materials in complex shapes without the need for expensive tooling or lithographic masks. We are designing polymer inks with tailored composition, viscosity to develop planar and complex 3D architectures. A myriad of polymer ink designs are under development, including colloidal, polyelectrolyte and sol-gel inks. Complex 3D structures have been produced with minimum feature sizes ranging from 3 µm to 300 µm. Specific fibre diameter and surface chemistry may facilitate control over behavior of cells, offering promising solutions in regenerative medicine.
