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.
Claims16
A method for printing with at least one bio-ink,
- the method comprising using at least one print head of the laser type to deposit at least one droplet of the at least one bio-ink onto a depositing surface of a receiving substrate, and using at least one nozzle print head to deposit at least one droplet of at least one bio-ink onto the depositing surface of the receiving substrate.
A method for producing a biological tissue, the method comprising:
- generating a three-dimensional digital representation of the biological tissue to be produced, with the representation comprising several colored or textured volume regions, with each color or texture being associated with a bio-ink;
- slicing the representation into a succession of stacked layers, with each layer comprising colored or textured regions which correspond to the volume regions of the representation;
- for each layer, determining the position of droplets to be printed of each bio-ink according to the colored or textured regions and an expected volume of each droplet;
- and
- printing the different droplets.
