Multi-material bio-printing facilities

Dispenser printing provides a method to produce 2D and 3D patterns from
basically any liquid phase material. Dispensing considered here is a form of
extrusion of material through a narrow diameter needle. An advantage of
dispensing technique over conventional printing techniques is the
avoidance of complicated ink formulation, which generally requires
hazardous organic solvents that may be harmful to biological objects.
Dispensing also allows materials with rather different properties such as
different viscosity to be printed in the same process. Combining the
dispensing printing of liquid phase materials and 3D printing of solid
materials, complex structures with new functional properties can be
fabricated, which is very challenging if not impossible using conventional
manufacturing techniques.
