Method and device for producing a three-dimensional, multi-cell object

A method for producing a three-dimensional, multi-cell object, comprising the following steps:

• a) introducing a first photopolymerizable liquid into a reaction vessel,
• b) focusing a first light beam on a first focal plane that lies within an area of the reaction vessel filled with the first liquid,
• c) producing a first polymerized structure in a first layer in the reaction vessel by way of the first light beam,
• d) introducing a further photopolymerizable liquid into the reaction vessel, so that a previously produced polymerized structure is at least partially covered with the further photopolymerizable liquid,
• e) focusing a further light beam on a further focal plane that lies within an area of the reaction vessel filled with the further liquid,
• f) producing a further polymerized structure in a further layer in the reaction vessel by way of the further light beam, wherein the further polymerized structure is arranged directly on the previously produced polymerized structure and is connected thereto,
• g) repeating steps d) through f) with one further photopolymerizable liquid each until the three-dimensional multi-cell object is produced,
• wherein the first photopolymerizable liquid and/or at least one of the further photopolymerizable liquids contain biological cells.
