Patent number: 11884010Abstract: A printing method employs a piece of equipment comprising an energy-delivering exciter that is orientable to produce a punctiform interaction with at least one ink that possibly contains non-uniformities and that is deposited on a printing medium including a transparent interaction area, in order to cause the transfer of a targeted portion of the ink to a receiver. The method includes a step of generating a wetting film at least partially covering the transparent interaction area, followed by a step of depositing the ink on the surface of the wetting film and transferring steps.Type: GrantFiled: March 20, 2020Date of Patent: January 30, 2024Assignee: POIETISInventors: Dan Soto, Fabien Guillemot, Bertrand Viellerobe, Aude Clapies

Patent number: 11517453Abstract: A bio-printing process comprises a step of preparing a target digital model representative of the three-dimensional organization of the tissue to be produced, a step of controlling a bio-printing instrument for the deposition of a plurality of layers of living cells and of biomaterials, a step of calculation of a digital printing model as a function of the digital model of the product to be produced, and of a model predicting change, and also characteristics of the constituents to be printed. The step of controlling the bio-printing instrument is carried out according to the digital printing model calculated in this way. A system is also described for implementing this process.Type: GrantFiled: March 8, 2018Date of Patent: December 6, 2022Assignee: PoietisInventors: Fabien Guillemot, Bertrand Viellerobe, Guillaume Simon, Guillaume Vandeneeckhoutte

Patent number: 11236296Abstract: An apparatus for transferring bio-ink onto a target having a slide defining a receiving area of a film of fluid containing inhomogeneities, a laser source associated with controlled diversion means and an optical block for focusing in a plane of the fluid film in order to apply a local pulse, wherein the apparatus also comprises imaging means and means for analyzing images in order to recognize the geometric positions of the inhomogeneities in the film, and an observable feature of each of the inhomogeneities (size, shape factor, type of particles, age of the particle, density, type of biomaterial, molecule, etc.) recognized by the appropriate analysis means. The apparatus further comprises selection means for selecting at least one of the inhomogeneous areas, and means for controlling the diversion in order to direct the laser beam toward the position of the inhomogeneous area and trigger the firing of the laser.Type: GrantFiled: March 8, 2018Date of Patent: February 1, 2022Assignee: PoietisInventors: Bertrand Viellerobe, Romain Vaucelle, Fabien Guillemot
