3D bioprinters, a 3D bioprinting toolhead and a method for 3D bioprinting a construct

A 3D bioprinter comprising a base unit,

• the base unit comprising a support adapted for mounting of a plurality of toolheads, wherein the support comprises a support part comprising a plurality of toolhead mounts, each adapted for mounting of an exchangeable toolhead,
• the base unit further comprising a communication interface part for communication of data with each mounted toolhead, the communication interface part being on or internal to the support on which at least one of the plurality of toolheads may be mounted, and
• the base unit further comprising a base unit processing element on or internal to the base unit and adapted to communicate with a toolhead processing element of a mounted toolhead over said communication interface part,
• wherein the base unit processing element is arranged to obtain over the communication interface part information related to a mounted exchangeable toolhead from a toolhead processing element of the mounted exchangeable toolhead, and perform the process of controlling the operation of the mounted exchangeable toolhead at the support based on the obtained information, when the exchangeable toolhead is mounted on the support of the base unit,
• wherein the plurality of exchangeable toolheads comprise information related to at least one of
• I.) an actuator type such as printing technology of the exchangeable toolhead, said information defining that the exchangeable toolhead is a pneumatic extrusion toolhead, syringe pump toolhead, inkjet toolhead, high temperature extrusion tool head, a tool head for removal of material and/or curing toolhead, or
• II) a sensor technology of the toolhead, said information defining that the exchangeable toolhead is a camera toolhead, probing toolhead and/or 3D scanning toolhead,
• and
• wherein the support is adapted to allow an exchange of a toolhead at one toolhead mount during an ongoing actuation at another toolhead mount.
