Bioprinting involves simultaneously depositing living cells and biomaterials layer by layer to make living tissue such as artificial structures of the skin, heart valves, cartilage, heart tissue, kidneys, liver and on other vital organs or hollow structures such as the bladder as well as vascular structures.
- a device for printing biological elements by laser based on the technique called “Laser Induced Forward Transfer” (LIFT) in English is described in European patent EP3234102. It comprises a pulsed laser source emitting a laser beam, a system for focusing and orienting the laser beam, a donor support which comprises at least one biological ink and a receiver substrate positioned so as to receive the material emitted from the donor support.
- LIFT Laser Induced Forward Transfer
- the laser beam impacts the donor support by being oriented in an approximately vertical direction and in a direction from top to bottom, ie in the same direction as the gravitational force.
- the biological ink is placed under the slide so as to face downwards in the direction of the receiving substrate which is placed under the donor support.
- a plurality of individual sterilizable chambers can be aseptically connected to an array of sterilizable chambers which provides additional functionality for the manufacturing assembly.
- This solution is not intended for biological printing, uses a heating head for the coating of active pharmaceutical ingredients.
- Patent application W02018072265 describes a 3D printing system based on a coordinated control with multiple axes and a measurement of artificial vision, comprising a machine frame, a work bench intended to be used to place an artificial bone support, a printing device arranged above the work bench, a material transport device for use in the transport of printing materials, image capture devices, a drive mechanism for adjusting the orientation of the printing device and a control system; the printing device, the material transport device, the image capture devices and the drive mechanism are all connected to the control system, the work bench is a parallel platform with six degrees of freedom which is connected to the machine frame, the drive mechanism is a six-axis robotic arm and the printing device is connected to the six-axis robotic arm.

- a dispenser of material intended to place said material on the table to form said object, provided with second means of movement of at least one container, at least one nozzle, and at least one extrusion member
- the solutions of the prior art generally relate to additive printing solutions of inert materials, and not bio-printing, resulting in particular constraints related to the living nature of some of the transferred objects (living cells). , the need for precise positioning to take into account the subsequent evolution during cell growth and decay and the structure of the biological tissue to be produced.
- the target is fixed during the printing phase, and the object print head (or “donor") is moved to position the elements to be transferred on the activation axis passing through the target point on the target.
- This solution has several drawbacks. Indeed, the displacement of the donor causes hydrodynamic disturbances of the carrier fluid in which the elements to be transferred are generally in suspension, particularly in laser printing. These disturbances induce positioning errors, targeting of objects and ultimately reproducibility of printing conditions. This constitutes a major limitation of existing solutions, in particular when it is desired to print at high resolution with a necessary reproducibility.
- this solution is not optimized for non-planar targets, for example a target intended for the bioprinting of a cardiac or vascular valve.
- the term "printing phase” means the period during which the donor is subjected to a repetition of activations, between the start of the bioprinting and the end of a sequence of donor activation pulses.
- the present invention relates, in its most general sense, to a bio-printing system for the manufacture of a structured biological material, from materials at least part of which consists of living biological particles (cells and cellular derivatives) in accordance with claim 1.
- the print heads remain fixed during the printing step, whatever the technology used (laser, by nozzle, acoustics, etc. ).
- the robot arm also ensures positioning in terms of distance between the target and the head: the donor - recipient distance. This must be known and maintained during the printing phase because it constitutes one of the parameters strongly influencing the shape and the quantity of the material deposited on the target substrate.
- the immobile nature of the printheads also makes it possible to instrument said printheads with characterization means (imagery, distance measurements, sensors, etc.) because they are linked to the frame of the bio-printer with sufficient space for integrate these measurement means, without the constraint of having to move them as is the case in the prior art.
- characterization means imagery, distance measurements, sensors, etc.
- said robot is a robotic arm with six degrees of freedom, three axes for positioning and three axes for orientation along at least 180 ° for each axis of rotation for moving and orienting said target in a given workspace , the travel stroke being greater than the largest dimension of said target,

- the bio-printer of which FIG. 1 or FIG. 6 illustrate exemplary embodiments consists of a frame, the lower part (11) of which cannot be sterilized, contains the bio-printing means (5), for example the optical head, the laser and imaging systems for a laser bio printer.
- the bio-printing means (5) for example the optical head, the laser and imaging systems for a laser bio printer.
- This frame is surmounted by a clean enclosure (hood type) or even sterilizable (insulator type) (10) constituted by a chamber with a blowing ceiling (hood) or under positive pressure supplied by a blower (insulator) (15) through a filter cartridge (16).
- a robotic arm (3) placed in this sterilizable chamber (10) ensures the movement of a target (6) relative to a print head (1).
- a watertight optical window (20) allows the transmission of the laser beam and imaging beams between the sterilizable enclosure (10) and the printing means (5) placed in a non-sterilizable area.
- the robotic arm (3) moves the target (6) in the work area during the printing phase, and outside this work area before the printing phase, to remove a target from stock blank targets, or in a maturation zone, after the printing phase.
- the robot (3) is constituted by an anthropomorphic robotic arm having, in known manner, six axes of rotation.
- the robot presented on the illustrations comes from the trade, designed and manufactured by the company STAUBLI ROBOTICS, it has the distinction of existing in a sterilizable version compatible with good manufacturing practices in the pharmaceutical field, therefore compatible with the manufacture of fabrics of clinical grade.
- It is fixed by means of a foot (2), and comprises four segments and two elbows (4, 7). These various elements are assembled in such a way that they can be pivoted relative to each other, around the axes of rotation.
- the last segment (8) generally carries a working tool constituted by an effector in the form of pliers (9) for gripping the target (6).
- Figures 2 to 5 illustrate a succession of positions of the arm (3) and the target (6).
- a support (30) is loaded with a plurality of blank targets (6, 31, 32, 33) ready to receive bio-printed elements.
- One of the targets (6) is extracted from the support (30) by the clamp (9) as shown in FIG. 3.
- the target (6) can be turned over as shown in FIG. 4 by pivoting the clamp (9), for example to print alternately on one side and on the other side.
- the target (6) is then positioned above the donor (1) and moved in the XY plane, and possibly along the Z axis, to very precisely position the target (6) so that the projection of the element coming from the donor (1) arrives at the location provided by the modeling program for the tissue to be printed.
- the distance between the donor and the receiving substrate constitutes for the majority of bio-printing technologies a very important parameter for the quality and reproducibility of the printing.
- the robot can at any time ensure a fixed or regulated value of this distance, even if the substrate is not planar.
- the printing area is isolated from the outside by an enclosure (10) which makes it possible to dissociate the power source (5) from the printing and handling area of the receiving substrate where is located the robot.
- This is a major difference from the examples of the prior art where the power source and printing area form a single entity.
- This dissociation provides a major advantage in terms of protection and stability of the printing process.
- the different positions of the robot described in this exemplary embodiment are sent to the robot via an automaton, of the SIEMENS type, which makes it possible to perfectly schedule and synchronize all the actions carried out by the different printheads and the robot during a bioprint.
- the scheduling and synchronization of the various elements described here must be carried out unequivocally and over very short times in order to ensure rapid printing in order to maintain the viability of the fabric being printed and the fidelity of what is printed compared to the original digital model.
- the robot's trajectory in this context corresponds to two types of operation:
- the robot thus makes it possible to manage the multimodal aspect of a bio-printer when it is equipped with several different printing and characterization methods.
- the robot can also make it possible to position the target opposite the donor for laser printing at the desired distance. In certain configurations, the robot will be able to pass from a high resolution laser print head (HR) to a low resolution laser print head (BR).
- HR high resolution laser print head
- BR low resolution laser print head
- the robot ensures the printing trajectory by movement X, Y (see Z) of the receiver.
- movement X, Y see Z
- the robot's performance in ensuring these two types of action, positioning and trajectory is very specific in terms of speed (up to 8 m / s) and precision ( ⁇ 20mpi).
- the weight moved by the robot is also an important criterion in terms of inertia.
- the robot is used to transport cell culture dishes or multi-well dishes which are very light objects which have no effect on the performance of the robot.
- the link between the robot and the target is ensured by an effector which generally takes the form of a clamp.
- This mode of implementation is particularly suitable for the production of curved biological tissue, for example heart valves, corneas, blood vessels, cartilage deposited on a prosthesis, ...
- the effector of the robot can support a rotary cylindrical mandrel to which the biological materials are transferred.
- Another advantage lies in the ability to easily reload the printhead (s) with bio-ink since they are linked to the frame of the bioprinter. We can even easily think of a change of the print heads or their reservoir without having to remove the print medium from the robot arm, allowing to maintain the 3D positioning of the object to be printed even when it requires a large quantity of raw material to be printed.
- the robot also allows the movement of the target with regard to a plurality of printheads, to alternate the bioprinting mode.
- the robot can move the target relative to a laser pulse transfer head to deposit the first series of biological materials, cells for example, then to an extrusion or inkjet printing nozzle to deposit second series of biological materials, of the extracellular matrix for example.
- the robot arm makes it possible to carry out movements similar to those of the human hand, which opens the way for displacements of the receiving support along trajectories ensuring preservation of the integrity of the shape of the printed object.
- the printed materials have a certain flexibility, or even more or less liquid parts. It is therefore necessary that the trajectories of movement of the target are studied so as not to disturb the printed layers, which makes it possible to do a robot arm which embeds the 6 degrees of freedom necessary for this capacity.
- the present invention proposes to take advantage of the automation of the printing processes by the contribution of said robot arm. Indeed, the arm will allow repeatable and precise prints to be produced while minimizing the manual operations of the users of the bioprinter.
- the arm serves: - in the stages prior to printing: preparation of the inks, pipetting, spreading of the inks, filling of the tanks, calibration, movement of a cover, drilling of a septum, etc.
- the arm will be able to position the target inside of it, make changes of environments, bring the target to a characterization means (imagery type), etc ...
- a nonlimiting example of donor preparation with the robot arm consists in using an effector which carries a pipette (40) controlled by an actuator.
- Said robot arm first positions the pipette above the reservoir containing the ink. Then, the actuator makes it possible to carry out several suction and ejection movements in order to mix and homogenize said ink. Then, the actuator makes it possible to take a controlled volume of ink and the arm transports this volume from the reservoir area to the print head where it ejects the volume of ink withdrawn from the donor.
- a special case of this example consists in using a disposable cone between each preparation of the donor. It is essential to be able to minimize the time between the end of donor preparation and the start of laser printing. To this end, the effector of the robot carrying the receiver can carry the pipettor and actuator system, thus minimizing the distances of movement between the deposition system. ink and the print receiving system.
- Figure 7 illustrates this example.
- donor preparation is based on the use of a pneumatic system.
- a positive and negative pressure controller makes it possible to push and draw the liquid
- a system of solenoid valves makes it possible to separate the pressure controller from the rest of the system
- a tube makes it possible to pneumatically connect the previous elements with a sampling head which may be a pipetting cone (50) for example.
- the reservoir containing the ink can be aliquoted beforehand with precise volumes (for example 12 m ⁇ per well in a 384 well plate).
- precise volumes for example 12 m ⁇ per well in a 384 well plate.
- the robot can also perform a procedure to calibrate the position of the printheads in space. Indeed, printing by extrusion or microvalve requires a perfect knowledge of the position of the printing needle relative to the surface of the receiver. As we say receiver is carried by the robot which positions it precisely in relation to these needles, we can add a function for measuring the position of the needles on the robot. Thus, it can recalibrate the position of the hands at any time.
- the measurement means for carrying out this operation can be of different types such as for example an optical fork, a mechanical probe, a camera, a laser beam, etc.
- the printing paths will be ensured by the robot arm itself, the printing heads remaining fixed.
- the printing time will therefore depend in part on the speed and precision of the robot, chosen according to the intended application and the type of object to be printed.
- the print file will also be specific since it is calculated relative to the position of the target and no longer relative to the position of the print heads as is the case in the prior art.
- the optimization of the printing trajectory strongly linked to the specifications of the robot and to the calculation of the printing pattern, is specific to the configuration described in the present invention.
- mathematical optimizations of the “traveling salesman” or machine learning type will make it possible to minimize the printing time, while guaranteeing the obtaining of the desired pattern and the conservation of the previously printed layers (no sudden or too rapid movements).
- the present solution is universal in the sense that the printing mode whether it is oriented upwards or oriented downwards is compatible with the use of a robot arm capable of rotating the target 360 °.
- the printing of cells by laser upwards and the printing of biomaterials downwards by extrusion or microvalve can be used jointly within the same bio-printer thanks to the contribution of the 6-axis robot arm, thus taking advantage of the best known configurations of each print mode.
- robot arm it would be possible to integrate several robot arms: for example, one could be used for pre-printing operations, another for printing and finally a final one for the post-printing phase. In this context, there would no longer be manual operations on the part of users. Different multi-robot configurations are possible in this context. One can also associate the robot arm with other automated or manual conveying means, whether they are part of the enclosure or not.
- the robot arm could transport several targets via one or more effectors in order to parallelize the prints with respect to several fixed print heads.
- This type of configuration is advantageous when the bioprinting requires significant flow rates in volume or in number of fabrics to be manufactured, in particular in a production mode.
- the robot arm (via its effector) could embed active functions such as lighting, imagery, heating, position sensors, etc. in order to instrument the target to allow:
- the robot arm is GMP compatible (pharmaceutical requirements) to allow the manufacture of clinical grade tissue.
- the system includes a station for acquiring a digital model of the target, consisting of a camera taking a series of images of the target moved by the robot.
- the system comprises one or more cameras analyzing the target, in particular a living or deformable target, to recalculate the position of an area of interest intended to receive the transfer of the biological material in the repository of the robot, the recalculating robot in real time the trajectory according to the configuration of said target.
- the robot positions, during an initialization phase, a position sensor in front of an extrusion head, to precisely calibrate the position of the distal plane of the orifice. nozzle extrusion.
- the system comprises means of human interaction for ensuring the movement of the target, and robotic means for controlling the movement of said robot.
- This variant makes it possible in particular to carry out learning of the movements or of the control of the movements by human action supplemented by the action of the robot.
- the robot controls the rotation of its effector to ensure the spreading of the bio-ink film in the context of laser printing.
- the system is controlled by a computer executing a program for controlling the articulations of the robot according to a trajectory optimization algorithm.
- a computer includes sensors for detecting the position of the robot and for example learning processes to determine the optimal trajectories.
- the system is designed to allow sterilization to allow implementation directly in a surgery block.
- the printing means for example laser, is located in the same space as the robot and the target.
- the printing means must be designed so as to minimize the emission of particles so as not to interfere with the printing process.
- This scenario corresponds to a situation where the entire bio-printing system is implemented in a single space which can be an enclosure that can be opened, a closed enclosure or even a room dedicated to bio- impression .
