Definitions
- the invention lies in the field of powder-based additive manufacturing by melting the grains of this powder using one or more energy or heat sources such as a laser beam and / or a electron beam and / or diodes.
- the invention is in the field of additive manufacturing by deposition of powder bed and it aims to prepare the production platform supporting different layers of additive manufacturing powder inside a machine. additive manufacturing by powder bed deposition.
- the invention aims to improve the quality of the first layer of powder deposited on the additive manufacturing platform.
- the quality of the first layer of powder deposited on the production plate is essential to ensure a good metallurgical bond between the parts to be manufactured and this plate.
- the objective is to obtain a first layer of powder uniformly distributed over the entire upper surface of the additive manufacturing plate, that is to say a first layer of powder having a substantially constant powder thickness in all point of the upper surface of the additive manufacturing tray.
- Different parameters can affect the quality of this first layer of powder: the particle size of the powder, the chemical composition of the powder, the degree of moisture of the powder, the type of device used to spread the powder (raclette or roll for example), the surface condition of the top surface of the production tray, etc.
- the additive manufacturing trays are machined and rectified before being mounted in the additive manufacturing machine, in order to have the desired tolerance parallelism between the lower surface and the upper surface of the tray.
- the present invention therefore provides a method of preparing an additive manufacturing plate by deposition of powder bed requiring no sanding machine or machining nor consumable to increase the roughness of the upper surface of the tray.
- the subject of the invention is a method for preparing the upper surface of an additive manufacturing plate by deposition of a powder bed, this method comprising at least one step of increasing the roughness of the powder. at least one area of the upper surface of the tray by printing a pattern on that area.
- the method of preparation provides that the printing of the pattern is performed inside the additive manufacturing machine by powder bed deposition in which the tray is then used for additive manufacturing by bed deposition of powder, the printing of the pattern being performed before a layer of powder is spread on the tray.
- the method of preparation provides that the pattern is printed on the upper surface of the tray with the same source of energy or heat which is then used for the selective melting of the powder, this source being preferably a source emitting at least one laser beam.
