    METHOD AND MACHINE FOR MANUFACTURING AT LEAST ONE PART
    AT LEAST ONE CERAMIC AND / OR METALLIC MATERIAL THROUGH
    TECHNIQUE OF ADDITIVE PROCESSES
    The present invention relates to a method and a machine for manufacturing parts by the technique of additive methods.
    These parts are in particular parts made of ceramic or metallic material obtained in the raw state and then subjected to cleaning, debinding and sintering operations to obtain the finished ceramic or metallic pieces.
    The technique of additive processes, also
    called stereolithography, comprises generally the following steps, for obtaining of such pieces state ceramics believed: - we build, by design power through computer a
    computer model of the part to be manufactured, model whose dimensions are larger than those of the part to be manufactured in order to provide for a withdrawal of the ceramic during the manufacture of the part; and
    - the part is manufactured by the technique of additive processes, a technique according to which:
    - A first layer of a photocurable composition is generally formed, on a rigid support or on a part during manufacture, generally comprising at least one ceramic material, at least one dispersant, at least one photocurable monomer and / or oligomer, at least a photoinitiator and at least one plasticizer;
    - The first layer of the photocurable composition is hardened, by irradiation according to a pattern defined from the model for said layer, forming a first stage;
    - A second layer of the photocurable composition is formed on the first stage;
    the second layer of the photocurable composition is made to harden, by irradiation according to a pattern defined for said layer, forming a second stage, this irradiation being carried out by laser scanning of the free surface of the spread photocurable composition or by a projection system diodes;
    - optionally, the above steps are repeated to obtain the part in the raw state.
    Then, to obtain the finished part, the part is cleaned in the raw state to remove the uncured composition; the part is cleaned in the cleaned raw state; and the part is cleaned in the raw state, cleaned and unbound to obtain the finished part.
    The procedure is the same in the case of a metallic material.
    If the manufacture of simple parts made of ceramic material or metallic material by this technology is well mastered, the manufacture of parts which have a complex shape and / or composition presents difficulties.
    The expression “parts of complex shape” is understood to mean in particular parts which have passages of three-dimensional geometry, such passages being difficult to clean properly because there are no tools adapted to these geometries.
    By parts of complex composition is meant in particular parts made of several ceramic or metallic materials.
    The Applicant Company discovered that such complex parts could be obtained by making one or more recesses in the layers of photocured ceramic or metallic composition, these recesses being filled, to complete the layer thus hollowed out, with a composition suitable for flow and then be hardened to reform a complete layer, on which we will spread the next layer of ceramic or metallic photocurable composition.
    The flowable composition can be another ceramic or metallic photocurable composition, which will make it possible to form multi-material parts, or a hardenable sacrificial material, which will be destroyed during debinding, freeing the hollow parts or passages made in the parts without the need for a cleaning tool or chemical.
    The present invention therefore firstly relates to a method of manufacturing at least one part made of at least one material chosen from ceramic materials and metallic materials by the technique of additive methods, said part or said parts being formed in the l 'raw state and being brought to be then subjected to cleaning, debinding and sintering operations, process according to which:
    (1) a computer model of the part to be manufactured or parts to be manufactured is constructed by computer aided design;
    (2) on a construction platform, said part or parts to be produced are formed, these being based on a photocurable ceramic or metallic composition (CPCb or CPMb) formed:
    - a mineral part consisting of at least one powdery ceramic material or at least one powdery metallic material; and
    - an organic part capable of being destroyed by heating during debinding and comprising at least one photocurable monomer and / or oligomer and at least one photoinitiator;
    characterized by the fact that:
    at least one material different from said basic CPCb or CPMb is prepared, capable of flowing and capable of being hardened once it has elapsed, said material being a sacrificial organic material (MOS) capable of being destroyed by heating during debinding or a additional ceramic or metallic composition CPCs or CPMs;
    for the construction of said part or said parts, on the construction platform, successive layers of CPCb or CPMb are formed which are each time cured by irradiation according to the pattern previously defined from the model for said layer , the following steps being carried out to form hollow parts of the part and / or to incorporate at least one part made of another ceramic or metallic material:
    forming by machining at least one recess in at least one layer of hardened CPCb or CPMb from the upper surface thereof;
    deposit in said recess (s) of a MOS or CPCs or CPMs to fill it or fill them;
    hardening of the MOS or CPCs or CPMs placed in said recess (s) to obtain a hard horizontal surface of the same level as the neighboring layer of CPCb or CPMb, at each formation of recess (s), this or these being delimited according to the pattern (s) previously defined from the computer model, and its depth (s), chosen to ensure the continuity of the part or parts to be manufactured, one or more recesses can also be formed in a layer part constituted by a CPCs or CPMs to insert another CPCs or CPMs there, and one obtains, once the stacking of the hardened layers carried out, one or more raw parts which can be subjected to a cleaning to remove the uncured part (s) , then debinding and sintering.
    The ceramic materials are the powdery sinterable ceramic materials chosen in particular from alumina (AI2O3), zirconia (ZrO2), alumina reinforced with zirconia, zirconia reinforced by alumina, zircon (ZrSiO-i), silica (S1O2 ), hydroxyapatite, silica zircon (ZrSiO4 + S1O2), silicon nitride, tricalcium phosphate (TCP), aluminum nitride, silicon carbide, cordierite and mullite.
    The metallic materials are the powdery sinterable metallic materials chosen from pure metals, such as Al, Cu, Mg, Si, Ti, Zn, Sn, Ni, their alloys and mixtures of pure metals and their alloys.
    The recesses may have to be formed over the entire thickness of a hardened layer of CPCb or CPMb or over a height less than the height of a layer. They may also be able to be formed over a height greater than the thickness of a layer, for example over a height equal to the height of several layers spread out beforehand.
    When the part or parts to be constructed have hollow parts, these must open onto the external surface so that the MOS can be removed during debinding.
    It is possible to use a CPCb or a CPMb of pasty consistency which is spread out in a layer by scraping or a CPMb or CPCb in suspension which is applied by immersion of the platform in a bath of said suspension to form each time the layer of CPCb or CPMb to be hardened, and scraping of the layer thus formed.
    It is possible to use, as MOS, a photocurable material comprising at least one photocurable monomer and / or oligomer and at least one photoinitiator; or a hot-melt plastic material to be able to flow, in particular to be able to flow under pressure, in a recess and hardening when returning to ambient temperature.
    Such thermosetting plastics are especially chosen from acrylonitrile-butadiene-styrene (ABS) copolymers, polycarbonates (PC) + ABS, PC-ISO polycarbonates, polyetherimides, polyphenylsulfones, nylon, polyvinyl alcohol, polyurethane thermoplastic, copolyesters, polypropylene and polylactic acid.
    By ceramic or metallic photocurable compositions CPCs or CPMs different from the composition respectively CPCb or CPMb, is meant not only compositions which are of different chemical nature but also compositions which may be chemical but which may have different ones, such as the density, be of the same kind physical properties which cannot be obtained with a single spreading system.
    For the formation of the recess (s), mechanical machining can be carried out. It is also possible to conduct laser machining, in particular under conditions for adjusting the power of the laser between 1 and 3 watts and the speed of movement of the laser between 1 and 100 millimeters per second.
    Also, at each machining step, one can blow and one can vacuum the debris at the same time as one carries out said machining.
    The MOS or CPCs or CPMs can be applied in the recess (s) by a distribution nozzle.
    The hardening can be carried out by laser irradiation of each layer of MOS or of CPCs or CPMs under the conditions of an adjustment of the laser power between 70 and 700 milliwatts and a speed of movement of the laser between 1000 and 6000 millimeters per second, and layers of photocurable MOS placed in the recesses.
    The present invention also relates to a machine for manufacturing at least one part from at least one material chosen from ceramic materials and metallic materials by the process using the technique of additive processes as defined above, characterized by fact that it includes:
    a frame framing a construction platform comprising a work surface;
    means for feeding and spreading in layers on the construction platform of a basic ceramic or metallic photocurable composition (CPCb or CPMb);
    machining means capable of forming at least one recess in a layer of photocured CPCb or CPMb from the upper part thereof;
    means for blowing and suctioning debris resulting from said machining;
    means for filling the recess (s) formed in each layer of photocured CPCb or CPMb to complete the layer thus hollowed out with a sacrificial organic material (MOS) or ceramic or metallic photocurable composition (CPCs or CPMs) capable of flowing;
    irradiation means located above the work surface and capable of irradiating each layer of CPCb or CPMb once spread to harden it and to irradiate, to make it hard, the MOS - when it is photocurable - , CPCs or CPMs once placed in the recesses made in hardened CPCb or CPMb layers.
    Such a machine, capable of applying a CPCb or CPMb in layers in the form of a paste, may comprise a gantry provided with at least one scraper blade and capable of moving on the frame above the work surface so that the free edge of the scraper blade (s) is able to spread the layers of CPCb or CPMb paste on the work surface, or the CPCb or CPMb being brought by at least one displaceable dispensing nozzle in front of at least a scraper blade which spreads the CPCb or CPMb in a uniform layer as it passes over it.
    A such machine, able to apply in layers a CPCb or CPMb under the form of a suspension, can include a tray to fill by said suspension, in which the suspension platform East able to descend step by step to train on it to each step one layer to irradiate, and a scraper ( ' recoater ") for
    ensure that the suspension is distributed over the entire surface to be irradiated.
    The means for bringing at least one MOS or a CPCs or a CPMs onto the work surface can be constituted by at least one dispensable nozzle movable above a corresponding recess to apply the corresponding composition therein. .
    According to a first embodiment, the or at least one of the nozzles can be supplied with MOS or CPCb or CPMb or CPCs or CPMs by a flexible pipe connected to a tank, in particular a piston supply tank.
    According to a second embodiment, the or at least one of the nozzles can be supplied with MOS or CPCb or CPMb or CPCs or CPMs by a cartridge of which it forms the upper part, which contains a reserve of MOS or CPCb or CPMb or CPCs or CPMs and which is refillable from a supply tank mounted or not on the machine or which is replaceable when it is empty by a full cartridge, this replacement can be ensured by a robotic arm.
    The or at least one of the nozzles can be mounted displaceable using a robotic arm; or on a gantry which comprises both a slide making it possible to move it along the horizontal axis x of the construction platform and a slide making it possible to move it along the horizontal axis y of the construction platform; or on a gantry provided with at least one scraper blade to allow its displacement along the horizontal axis x in advance of the scraper blade, said gantry also comprising a slide making it possible to move it along the horizontal axis y.
    To better illustrate the object of the present invention, there will be described below, by way of indication and not limitation, a particular embodiment with reference to the accompanying drawing.
    On this drawing :
    - Figure 1 is a schematic perspective view of a machine for manufacturing a green part in at least two ceramic materials by the technique of additive processes;
    - Figure 2 is, on a larger scale, a front view of the gantry for moving the application nozzles of two different photocurable compositions; and
    - Figures 3 to 8 illustrate the successive stages of the construction of a part from three different photocurable compositions.
    If we refer to Figure 1, we can see that there is shown schematically a machine 1 for the manufacture of a green part based on three different photocurable compositions.
    The machine 1 comprises a device 2 for scraping a layer of dough on a working surface of a horizontal construction platform 3.
    The scraper device 2, slidably mounted on the frame 4 of the machine, comprises a gantry 5 carrying at the front a scraper blade 6 having a horizontal scraper edge.
    The machine 1 also includes a structure 7 which supports a gantry 8 for moving two nozzles 9 and 10.
    The structure 7, arranged above the scraper device 2, comprises two longitudinal members 7a joined by cross members 7b. Each spar 7a carries, along its lower face, a projecting part 7c (Figure 2).
    On these projecting parts 7c, the gantry 8 for moving the nozzles 9 and 10 is slidably mounted. The gantry 8 is constituted by a vertical plate 8a comprising, at its upper part, a square return 8b which comprises elements 8c cooperating with the projecting parts 7c for the sliding of the gantry 8 on the structure 7.
    The plate 8a also comprises two horizontal projecting parts 8d on which a vertical support 11 of the nozzles 9 and 10 is slidably mounted, this comprising, at its rear part, elements 11a allowing this sliding.
    The support 11 has, in the example shown, two branches 11b which are folded, at their lower part, to support one the nozzle 9 and the other, the nozzle 10.
    Each nozzle 9, 10 is surmounted by a refillable cartridge respectively 9a, 10a which contains a reserve of photocurable composition.
    Furthermore, the support 11 carries, at its lower part, a horizontal frame 12 which surrounds the nozzles 9, 10 and to which are connected a debris blowing nozzle 13 as well as a debris suction nozzle 14.
    In Figure 1, there is also shown the galvanometric head 15 which directs the laser beam.
    It can therefore be seen that the scraper device 2 is mounted capable of moving along the x axis, that the gantry 8 and the support 11 are able to move respectively along the y axis and along the x axis.
    We will now describe the operation of the machine which has just been described with reference to Figures 3 to 8. To each of these Figures is associated a square representing, on a larger scale, the top view of the part of the part in construction.
    Figure 3
    A layer of ceramic paste is deposited on the construction platform 3 using the scraper device 2, which moves along the x axis.
    Figure 4
    The layer thus deposited is brought to polymerize in the square part by application of the laser beam.
    Figure 5
    A laser machining of the layer which has just been hardened is carried out in order to form therein three recesses El, moving along the axis y and the support 11, along the axis x, this laser machining operation s' performing with blowing and aspiration of debris at the same time as lasing.
    Figure 6 the
    With the aid of El, photocurable recesses. We have it

    We carry out a laser machining of the layer which has just been deposited in the recess E2 to form recesses E4 there, the gantry 8 moving along the y axis and the support 11, along the x axis, this operation machining is carried out with blowing and suction of debris at the same time as lasing.
