Definitions

  • a process of three-dimensional (3D) printing by a fused filament fabrication technology various types of materials (substrates) may be utilized for 3D printing with different physicochemical properties.
  • the physicochemical properties of a material constitute important information required by a 3D printer, for successfully printing a desired physical model.
  • Such physicochemical properties reflecting a spatial model and defining the specific printing parameters are saved in the form of unique machine codes, which control the printing process.
  • machine codes are produced by a spatial printer controller, which may exist within the printer or an external computer with dedicated software is used as a controller that is operably connected to the 3D printer.
  • the course of the printing process, visual quality and mechanical properties of the printed model depend on the parameters of the spatial printing process, which are different for each type of printing material.
  • the method comprises the following steps: recording encrypted communication data onto the digital tag, enabling the 3D printer to connect and communicate with an external server; applying the digital tag to the container that holds the printing material; inserting the container into the 3D printer, whereupon the 3D printer communicates with the external server, and then downloads and decrypts the encrypted printing parameters housed within that server; generating in the controller printing machine codes for controlling the printing process based on the decrypted printing parameters and, preferably based on the spatial model specifications; printing a physical model based on the generated printing machine code.
  • Fig. 1 - presents a diagram of controlling a 3D printing process in which a controller housed within a 3D printer is responsible for generating machine codes based upon decrypted printing parameters (derived from a digital tag applied to a container that with printing material) and a printed spatial model.
  • Fig. 2 - presents a diagram of controlling a spatial printing process in which a controller housed within an external computer is responsible for generating machine codes based upon decrypted printing parameters (derived from a digital tag applied to a container with printing material) and a printed spatial model.
  • Fig. 3 - presents is a diagram of controlling a spatial printing process in which printing parameters are downloaded from an external server, such that a controller housed within a 3D printer is able to generate machine codes after decryption of printing parameters received from the server.
  • printing materials include PC, PA, PEI, PAEK, ABS, PLA, materials consisting of glass, carbon, or other fibers; materials consisting of wood, metals, ceramics, and other fillings; materials that are conductive, flexible, or soluble; and many other types of specialty and non-standard printing materials.
  • the digital tag 10 - which stores the encrypted printing parameters - may consist of a passive radio identification tag or microchip.
  • Other types of encryption may be employed in the present invention. Examples of currently-available technique may include the Data Encryption Standard (DES), TripleDES, RSA, Advanced Encryption Standard (AES), Twofish, or others.

  • the printing parameters are decrypted and communicated to a controller 18 of the printer.
  • a file with the numerical description of a spatial model 16 is also communicated to the controller 18, such as through a user interface of the 3D printer.
  • the file with the spatial model 16 includes data and measurements (in a form that may be interpreted by the controller 18) that reflect the desired three-dimensional shape and dimensions of the physical object (the desired physical model 20) to be printed.
  • Printing machine codes based upon the printing parameters and the spatial model 16 are generated in the controller 18. Once the machine code has been generated, the printing process is controlled by means of the controller 18 and the physical model 20 is printed.
  • the machine codes are then subsequently delivered to the 3D printer 14 via the external server 24, and the physical model 20 is printed on the 3D printer 14.
  • An advantage of the invention is a higher level of protection of confidential and proprietary spatial printing parameters against known solutions.
  • the printing parameters are not embodied within the software that is required to generate machine codes, therefore they do not have to be available to the user when using specific materials.
  • Data stored onto a digital tag can be encrypted with a strong algorithm whose decoder is only housed within a printer controller. These data are only readable using advanced techniques that require irreversible damage to the printer components.

Abstract

Cette invention a pour objet un procédé de commande d'un processus d'impression tridimensionnelle (3D) comprenant la préparation d'un fichier avec des spécifications applicables pour un modèle spatial (16) et l'application d'une étiquette numérique (10) sur un récipient (12) qui contient un matériau d'impression, les paramètres d'impression ou les données de communication permettant la connexion avec un serveur externe étant enregistrés sur ladite étiquette numérique (10). Lorsque le récipient (12) est inséré dans une imprimante 3D (14), les données sont lues et extraites de l'étiquette vers un dispositif de commande (18), des codes machine étant générés sur la base des données reçues afin de commander le processus d'impression d'un modèle physique (20).
