Description

[0001] This application is a divisional application of the application with the application number 202210065932.9, the application date of January 20, 2022, and the invention name of "a manufacturing method of three-dimensional objects and consumable assembly". TECHNICAL FIELD

[0002] The present application relates to the technical field of 3D printing, in particular to a manufacturing method of three-dimensional objects and a consumable assembly. BACKGROUND

[0003] The current light-cured 3D printer includes a forming platform, a tray and a light source. The light source projects light to the bottom of the light-transmitting tray, so that the photopolymerizable material between the forming platform and the bottom of the tray undergoes a polymerization reaction to obtain a solidified sheet. The solidified sheet is bonded to the forming platform. By moving the forming platform away from the bottom of the tray, and simultaneously making the light source project light source to the bottom of the tray intermittently or uninterruptedly, the solidified sheet is solidified layer by layer, and the stacked solidified sheet is finally formed into a three-dimensional solid printed part.

[0004] After printing is completed, the user needs to shovel the printed part from the forming platform. Thus, the forming platform is a consumable. As the number of printing increases during the 3D printing process, the flatness and roughness of the forming surface of the forming platform may not meet the printing requirements, which may result in poor printing accuracy or printing failure. Therefore, the forming platform needs to be cleaned and maintained after each printing, and the forming platform needs to be replaced after a certain number of uses. However, it is difficult for the user to determine the service life of the forming platform and bear the risk of printing failure. Therefore, it is necessary to provide a manufacturing method of three-dimensional objects and a consumable assembly to solve the above problems. SUMMARY

[0051] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0052] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0053] Figure 1 This is a step diagram illustrating the manufacturing method of the three-dimensional object provided in this embodiment. Please refer to... Figure 1 This embodiment provides a method for manufacturing a three-dimensional object, the method comprising:

[0054] S01: Perform photopolymer 3D printing to form a three-dimensional object 104 on the forming platform 101 using photopolymerizable material.

[0055] Figure 2 This is a schematic diagram of the structure during step S01 in the manufacturing method provided in this embodiment. Please refer to... Figure 2 In this embodiment, when performing photocurable 3D printing, the molding platform 101 is placed on the upper side of the material tray 102, and the light source 103 projects light into the light-transmitting material tray 102 at the bottom. The light passes through the material tray 102 and irradiates the photocurable material between the material tray 102 and the molding platform 101, causing the photocurable material to undergo a polymerization reaction and form a three-dimensional object 104 bonded to the molding platform 101. This step is the printing step.

[0056] It should be noted that in this embodiment, the three-dimensional object 104 is directly bonded to the molding platform 101. It is understood that in other embodiments, the object is bonded to the molding platform 101. Figure 3 Alternatively, depending on the requirements, before molding the three-dimensional object 104, a support structure 109 can be formed on the molding platform 101 using a photocurable material. In this way, the subsequently molded three-dimensional object 104 is connected to the molding platform 101 through the support structure 109, that is, both ends of the support structure 109 are connected to the molding platform 101 and the three-dimensional object 104 respectively (e.g., ...). Figure 3 (As shown).

[0057] The molding platform 101 used in the manufacturing method of the three-dimensional object provided in this embodiment is a one-piece component. Optionally, the molding platform 101 can be at least one of a one-piece molded plastic part, a straw part, and a metal part, thereby helping to reduce the cost of the molding platform 101. Its manufacturing methods include, but are not limited to, injection molding, 3D printing, vacuum forming, blow molding, and extrusion molding. Optionally, the thickness of the molding platform 101 is 1mm-5mm, so that the cost of the molding platform 101 can be reduced as much as possible while ensuring that the molding platform 101 has reliable mechanical properties.

[0058] In this embodiment, the molding platform 101 is a one-piece molded plastic part. The plastic part undergoes surface treatment to give the surface of the molding platform a fine texture, or to increase the surface roughness of the molding platform 101. This increases the adhesion between the surface of the molding platform 101 and the three-dimensional object 104, preventing the surface from peeling off. Optionally, at least one of the following methods can be used to treat the plastic part: texturing, EDM, sandblasting, electroplating, spray painting, screen printing, laser engraving, water transfer printing, texturing, precision machining, film application, chemical etching, and wire drawing.

[0059] Since the molding platform 101 is a single-use component, after printing is completed and it is separated from the three-dimensional object 104, the user can directly discard the molding platform 101 without subsequent maintenance, upkeep or cleaning. The molding platform 101 is in good condition and no adaptation treatment is required when changing materials, such as cleaning the platform.

[0060] Optionally, in this embodiment, the molding platform 101 has a bowl-shaped structure. It is understood that in other embodiments, the structural form of the molding platform 101 can also be specifically set according to the needs, such as setting the molding platform 101 as a flat plate, cup, or disc.

[0061] S02: Perform post-processing on the 3D object 104.

[0062] After the 3D object 104 is printed, it can be post-processed. Since the 3D object 104 is not detached from the forming platform 101 at this time, the forming platform 101 moves with the 3D object 104 during post-processing. That is, the forming platform 101 and the 3D object 104 are post-processed together. The printed part can be removed after the post-processing is completed, making the operation more convenient.

[0063] In this way, during the post-processing process, the molding platform 101 can serve as a carrier for subsequent operations on the three-dimensional object 104. For example, the user can directly pick up the molding platform 101 to transfer the three-dimensional object 104, and the molding platform 101 can also serve as a connecting structure between the post-processing equipment and the three-dimensional object 104. That is, the connection between the three-dimensional object 104 and the post-processing equipment is achieved through the connection between the post-processing equipment and the molding platform 101. This can prevent the three-dimensional object 104 from deforming or breaking during the post-processing and transfer process. At the same time, the fixtures or locking mechanisms of each post-processing equipment can be set as universal parts, which can save development time to a certain extent.

[0064] Figure 4 This is a diagram illustrating the sub-steps of step S02 in the manufacturing method provided in this embodiment. Please refer to... Figure 4 Specifically, in this embodiment, step S02 includes:

[0065] S21: Remove printing material from the surface of 3D object 104.

[0066] At least one of centrifugation, spraying, and ultrasonic treatment can be used to remove printing material from the surface of a three-dimensional object. It is understood that the removal method is not limited here, and obviously, other methods that can remove printing material from the surface of a three-dimensional object can also be used.

[0067] Figure 5This is a schematic diagram of the structure during step S21 of the manufacturing method provided in this embodiment. Please refer to... Figure 5 In this embodiment, the printing material on the surface of the three-dimensional object 104 is removed by centrifugal shaking. Specifically, the printing material on the surface of the three-dimensional object 104 is liquid photosensitive resin. This step specifically includes:

[0068] The forming platform 101 is connected to the centrifuge device 105. The centrifuge device 105 drives the forming platform 101 to rotate, and the 3D object 104 rotates synchronously with the forming platform 101, thereby removing the printing material adhering to the 3D object 104. Simultaneously, before or during the rotation of the forming platform 101 by the centrifuge device 105, a cleaning fluid is sprayed onto the 3D object 104 on the forming platform 101. Specifically, after the forming platform 101 is connected to the centrifuge device 105, a spray device 106 is provided on one side, through which the cleaning fluid is sprayed onto the 3D object 104. Optionally, the cleaning fluid is a solvent that can dissolve the printing material, thus reducing the viscosity of the printing material and making it easier to remove.

[0069] S22: The three-dimensional object 104 is processed using a curing device to deeply cure the three-dimensional object 104.

[0070] In this embodiment, a curing device is used to process the three-dimensional object 104, thereby enabling the three-dimensional object to be deeply cured quickly. It is understood that in other embodiments, methods such as drying without a curing device can also be used to achieve deep curing of the three-dimensional object 104.

[0071] Figure 6 This is a structural diagram illustrating step S22 in the manufacturing method provided in this embodiment. Please refer to... Figure 6 In this embodiment, the curing device includes a curing lamp 108. The curing lamp 108 irradiates the three-dimensional object 104, thereby deeply curing the three-dimensional object 104 and improving its mechanical properties. Furthermore, while the curing lamp 108 is irradiating the three-dimensional object 104, the molding platform 101 and the three-dimensional object 104 on it rotate relative to the curing lamp 108, allowing the curing lamp 108 to comprehensively irradiate all parts of the three-dimensional object 104, resulting in uniform curing and a good curing effect.

[0072] Optionally, in this embodiment, the curing device further includes a rotating device 107, and the molding platform 101 is connected to the rotating device 107, so that the rotating device 107 drives the molding platform 101 to rotate relative to the curing lamp 108, and the three-dimensional object 104 on the molding platform 101 rotates relative to the curing lamp 108 accordingly.

[0073] It should be noted that in this embodiment, the relative rotation of the molding platform 101 and the curing lamp 108 is achieved by rotating the molding platform 101. It is understood that in other embodiments, the relative rotation of the molding platform 101 and the curing lamp 108 can also be achieved by rotating the curing lamp 108 while keeping the molding platform 101 stationary. Alternatively, both the molding platform 101 and the curing lamp 108 can be set to be rotatable, but their rotation speed or direction of rotation is different.

[0074] Optionally, there may be multiple curing lamps 108, which are distributed around the rotation axis of the molding platform 101, i.e., multiple curing lamps 108 are arranged around the molding platform 101 and the three-dimensional object 104. In this embodiment, there are two curing lamps 108. It is understood that in other embodiments, the number of curing lamps 108 can be specifically set according to needs, such as three or four.

[0075] It should be noted that the specific structure of the curing equipment is not limited here. It is understood that in other embodiments, the structure of the curing equipment can also be set according to the needs. For example, the curing equipment can be set to also include a heat curing device (such as an oven) so that the three-dimensional object 104 can be cured by a dual light-heat curing method. Alternatively, the curing equipment can be set to also include a humidifying device so that the three-dimensional object 104 can be cured by a dual light-humidity curing method.

[0076] In this embodiment, the molding platform 101 has identification information 110, which stores production data and can be stored using one or more of the following methods: QR code, character code, numeric code, barcode, special pattern, NFC tag, RFID tag, and electronic chip. It is understood that in other embodiments, other existing methods capable of storing and identifying data can also be used to identify the molding platform 101.

[0077] Optionally, the identification information 110 includes at least one of the following: the type of photocurable material, the printing parameters of the 3D object 104, and the process parameters of the post-processing equipment. The post-processing process parameters can be obtained directly by acquiring the identification information 110, or the corresponding post-processing process parameters can be matched based on data such as the type of photocurable material and the printing parameters of the 3D object 104 in the identification information. The post-processing process parameters may include the type of post-processing, as well as corresponding control parameters during cleaning and control parameters of the curing equipment.

[0078] In this embodiment, the production data stored in the identification information 110 on the molding platform 101 includes process parameters for post-processing of three-dimensional objects. Thus, after the identification information 110 is identified and obtained, the post-processing process parameters can be determined based on the identification information 110, such as the composition of the sprayed cleaning fluid, the irradiation time of the curing lamp 108, etc., which facilitates the control of the corresponding post-processing equipment to perform corresponding operations according to the process parameters.

[0079] The identification information 110 may also include printing parameters, etc.

[0080] The printing parameters include the slice file of the 3D object 104 and the control parameters of the printer. Specifically, the printing parameters can be pre-entered into the identifier of the forming platform 101 before printing. During the printing process, the printer reads the information stored in the identifier, obtains the printing parameters, and performs the printing operation according to the printing parameters, which is highly automated.

[0081] The control parameters during cleaning may include: the centrifugal speed of the centrifuge 105, the nozzle pressure of the spray device 106, the spraying time, the number of centrifugal rotations and sprays, and the process sequence. The control parameters of the curing equipment may include: curing time, rotation speed, stop time, stop angle, and rotation angle.

[0082] It should be noted that the data type in the identification information 110 is not limited here. It is understood that in other embodiments, the identification may also include other production data, such as the production time of the three-dimensional object 104, the user to which it belongs, the associated printer, etc.

[0083] S03: Separate the three-dimensional object 104 from the molding platform 101.

[0084] Figure 7 This is a schematic diagram of the structure during step S03 of the manufacturing method provided in this embodiment. Please refer to... Figure 7 In this embodiment, the three-dimensional object 104 is directly attached to the molding platform 101, so the three-dimensional object 104 can be directly removed from the molding platform 101.

[0085] Furthermore, in this embodiment, the step of separating the three-dimensional object 104 from the molding platform 101 follows step S02. Thus, during step S02, the three-dimensional object 104 moves synchronously with the molding platform 101. The molding platform 101 then serves as a support for the three-dimensional object 104 during step S02. Simultaneously, since the molding platform 101 is a single-use component, it can be discarded after the three-dimensional object 104 is separated from it. This eliminates concerns about potential damage to the molding platform 101 during subsequent processing steps. Moreover, the mechanical formation of the three-dimensional object 104 is further strengthened during separation from the molding platform 101, helping to prevent potential deformation or breakage of the three-dimensional object 104 after separation. It is understood that in other embodiments, step S03 can be performed before step S02, depending on the requirements.

[0086] It should be noted that when there is a support structure 109 between the three-dimensional object 104 and the forming platform 101 (e.g., Figure 3 When the structure shown is broken, the three-dimensional object 104 can be separated from the molding platform 101. At least a portion of the broken support structure 109 remains connected to the molding platform 101 (e.g., ...). Figure 8 (As shown), the molding platform 101 and its connected support structure 109 can then be discarded, which is convenient.

[0087] The method for manufacturing a three-dimensional object provided in this embodiment has at least the following advantages:

[0088] The method for manufacturing three-dimensional objects provided in the embodiments of the present invention utilizes a disposable molding platform 101. This eliminates the need for any adaptation treatment of the platform when changing materials, such as cleaning. In other words, it avoids subsequent maintenance, upkeep, and cleaning of the molding platform 101, ensuring its undamaged condition and guaranteeing printing quality and stability. Furthermore, since there is no need to consider damage or corrosion to the molding platform 101 during post-processing, it can be used as a support for the three-dimensional object 104 throughout the post-processing process after printing. The printed object can then be removed after post-processing, making placement and fixing more convenient. This also mitigates the problem of deformation and damage to the three-dimensional object 104 that might occur when separating the three-dimensional object 104 from the molding platform 101 before post-processing. The molding platform 101 is also equipped with identification information 110, which records the production information of the three-dimensional object 104 and identifies the process parameters of the printing and post-processing processes, making the production process more intelligent and contributing to improved production efficiency and quality.

[0089] Embodiments of the present invention also provide a consumable component, including a material tray (not shown) and multiple molding platforms 101. All molding platforms 101 are single-use components, and therefore can be used during the manufacturing process of a three-dimensional object 104 according to the aforementioned three-dimensional object manufacturing method. Simultaneously, the printing material pre-stored in the material tray can be used for the manufacturing of the three-dimensional object 104. In this embodiment, the printing material is a photocurable material. Furthermore, the amount of photocurable material pre-stored in the material tray allows for a preset number of uses, i.e., a preset number of three-dimensional objects 104 can be manufactured. After manufacturing the preset number of three-dimensional objects 104, the material tray can be discarded; that is, the material tray can also be considered a single-use component. The number of molding platforms 101 is matched to the preset number, thereby ensuring that the number of molding platforms 101 in a consumable component meets the usage requirements of the material tray; that is, the number of molding platforms 101 is greater than or equal to the preset number.

[0090] In this way, when manufacturing the 3D object 104, the corresponding consumable components can be selected according to the number of 3D objects 104 to be manufactured. For example, if two 3D objects 104 need to be manufactured, the amount of printing material pre-stored in the tray can be selected to correspond to the consumable components for two 3D objects 104. After manufacturing the required number of 3D objects 104, the pre-stored printing material in the tray can be used up, and the tray can be discarded directly. The printing material does not need to be saved for the next use, avoiding problems such as printing material deterioration, and thus avoiding quality problems of the 3D objects 104 due to printing material deterioration.

[0091] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
