Abstract
A method for printing uses at least one bio-ink. The method also uses at least one laser print head to deposit at least one droplet of at least one bio-ink onto a depositing surface of a receiving substrate. The printing method uses at least one nozzle print head to deposit at least one droplet of at least one bio-ink onto a depositing surface of the same receiving substrate as the laser print head.
Claims20
A printing system comprising:
- (a) a receiving substrate including a depositing surface;
- (b) at least one bio-ink including cells and an extracellular matrix;
- (c) at least one laser print head configured to deposit at least one droplet of the at least one bio-ink onto the depositing surface of the receiving substrate;
- (d) at least one nozzle print head configured to deposit at least one droplet of the at least one bio-ink onto the depositing surface of the receiving substrate;
- (e) the laser print head and the nozzle print head being integrated in the same machine and being moveable in the same coordinate system;
- and
- (f) laser beam-induced heat operably creating a bubble and upwardly moving the bio-ink from a bio-ink film to the receiving substrate.
