Description

Technical Field

[0001] The present application relates to the field of additive manufacturing technology, and in particular to a method for arranging multiple dental models. Background Art

[0002] Additive manufacturing, or 3D printing, has been widely used in dentistry due to its high precision, customization, and rapid prototyping capabilities. Dental treatments often require highly personalized solutions, such as crowns, bridges, implant guides, and invisible braces. Additive manufacturing can directly produce matching restorations or auxiliary devices based on a patient's digital oral model, significantly improving the efficiency and accuracy of diagnosis and treatment.

[0003] Dental restorations are categorized into fixed restorations, removable restorations, and implants. Each type requires different dental model features. For example, a dental mold for a fixed restoration has abutment features, while a dental mold for an implant has locators and gums.

[0004] When a manufacturer receives multiple orders, it classifies them based on the individual orders and prints the classified models of the same type on one or more formats or layouts. Thereafter, the models of the same category are printed in sequence.

[0005] The challenges faced by the above solution include: (1) Multiple similar models often cannot occupy one or more layouts. For example, a single layout allows printing of 5 dental models, but there are 8 first-type dental models to be arranged. In this case, two layouts are required, one for arranging 5 dental models and the other for arranging the remaining 3 dental models. Similarly, a single layout allows printing of 5 dental models, but there are 11 second-type dental models to be arranged. In this case, three layouts are required, two for arranging 5 dental models and the third for arranging the remaining 1 dental model. This obviously prolongs the printing time for a single order.

[0006] The challenges faced by the above solution include: (2) The sequential processing of different orders results in a longer total printing time for multiple orders. Summary of the Invention

[0007] The present application provides a method for arranging multiple dental models, the method comprising: dividing the multiple dental models into dental model models and non-dental model models; grouping at least two dental model models into a group; grouping at least one non-dental model model into a group; and arranging at least one group of dental model models and / or at least one group of non-dental model models.

[0008] In some embodiments, the multiple dental models are divided into dental model models and non-dental model models, including: dividing the multiple dental models of the same order into dental model models and non-dental model models.

[0009] In some embodiments, the multiple dental models are divided into dental model models and non-dental model models, including: dividing the multiple dental models of multiple orders into dental model models and non-dental model models.

[0010] In some embodiments, the dental model includes at least one of the following: a prototype dental model, an implant dental model, orthodontic dental model; the non-dental model includes at least one of the following: gums, abutment teeth, contact models, and abutment locators.

[0011] In some embodiments, a set of non-dental model models includes at least two non-dental model models and an attachment for connecting the two non-dental model models.

[0012] In some embodiments, laying out at least one set of dental cast models and / or at least one set of non-dental cast models includes: connecting a set of dental cast models and a set of non-dental cast models via an attachment.

[0013] In some embodiments, laying out at least one set of dental cast models and / or at least one set of non-dental cast models includes laying out the at least one set of dental cast models or non-dental cast models based on a ratio of a total projected area to a format area.

[0014] In some embodiments, laying out at least one group of dental cast models and / or at least one group of non-dental cast models includes laying out the at least one group of dental cast models or non-dental cast models based on a ratio of a total occupied area to a format area.

[0015] In some embodiments, at least one group of dental cast models and / or at least one group of non-dental cast models are laid out, including: sorting based on the height of at least one group of dental cast models or non-dental cast models, and then laying out based on the ratio of the total projected area or the total occupied area to the format area.

[0016] In some embodiments, a set of dental cast models includes at least two dental cast models connected along a height direction; and / or a set of non-dental cast models includes at least two non-dental cast models connected along a height direction.

[0017] In some embodiments, a set of non-dental cast models includes a plurality of objects having sharp ends, and the sharp ends of the plurality of objects are at different levels.

[0018] The present application provides a method for manufacturing a plurality of dental models, comprising: the aforementioned method of arranging a plurality of dental models; and obtaining the plurality of dental models by additive manufacturing.

[0019] This application balances the efficiency of batch 3D printing with the ease of subsequent sorting. Models are laid out based on at least one of category, order information, projected area, and occupied area, reducing the frequency of incomplete layouts. It also ensures that multiple objects in a single layout belong to the same order, minimizing the difficulty of subsequent sorting and packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] Figures 1A-1E Some dental objects are shown.

[0036] Figure 1A A schematic diagram of a dental prototype is shown. The dental prototype has a through hole, the diameter of which is, for example, greater than 2.5 mm or 3 mm. The dental prototype is typically a quarter-mouth or half-mouth model.

[0037] Figure 1B A schematic diagram of a dental implant mold is shown. The dental die has an implant hole, which typically has threads for engaging with the implant. In some embodiments, the implant hole has an anti-rotation feature (e.g., a depression). The diameter of the implant hole is, for example, about 3 mm. The top of the implant hole is, for example, round. Dental implant molds are typically 1 / 4 mouth and half mouth models.

[0038] Figure 1C A schematic diagram of an orthodontic dental cast is shown. Orthodontic dental casts do not have through-holes for orthodontic functions. Orthodontic dental casts are typically quarter-mouth and half-mouth models.

[0039] Figure 1D A schematic diagram of the gum is shown. The gum height is, for example, 1 mm to 3 mm. The gum has, for example, a substantially flat bottom surface and at least one through-hole for an abutment. The gum model is a closed solid.

[0040] Figure 1E A schematic diagram of an abutment is shown. The abutment is generally cylindrical and has a substantially flat bottom surface.

[0041] In an exemplary embodiment, a manufacturer receives multiple orders O1 to O2, each requiring different types and quantities of dental objects. For example, order O1 requires 20 dental prototypes, 30 dental implant models, and 30 gingival abutments, while order O2 requires 10 dental prototypes, 15 orthodontic models, and 10 gingival abutments.

[0042] In some embodiments, the application is first classified based on order information. Figure 2In the flowchart shown, in step 202, multiple models are classified based on order information. For example, the order associated with a single model is confirmed by an identification symbol (such as a number, letter, or pattern). For example, the model file name includes "HEYGEARS-S-001", and the model file is judged to belong to the order "S" of the user "HEYGEARS" by identifying the name, and the character "001" indicates that it is the first model. In step 204, multiple models of the same order are divided into dental mold models and non-dental mold models. For example, the order "S" of the user "HEYGEARS" involves models "001" to "040" (a total of 40 models). At this time, based on the model features (reference Figures 1A-1E ) These models are classified into dental cast models and non-dental cast models. The volume or projected area of ​​the non-dental cast model is substantially smaller than the volume or projected area of ​​the dental cast model. In step 206, at least two non-dental cast models are grouped together. For example, two gum models are grouped together, or three or more abutment models are grouped together, or two gum models and two abutment models are grouped together. In step 208, at least one group of non-dental cast models and / or at least one group of dental cast models are laid out. For example, three groups of non-dental cast models and five dental cast models are laid out (for example, a single dental cast model is grouped together). In some embodiments, the projected area of ​​a single group of non-dental cast models is 50% to 150% of the projected area of ​​a single dental cast model. In some embodiments, the two dental cast models in the "C" shape are staggered with each other to improve area utilization, so that more models can be arranged on a single page.

[0043] exist Figure 2 In the embodiment shown, all the webs for a single order are fully filled or occupied. Alternatively, except for the fully or completely filled web, a single web is not fully or completely filled, in which case a model of another order can be filled.

[0044] Figure 3A flowchart for multi-order processing is shown. In step 302, multiple models from multiple orders are classified into dental casts and non-dental casts. For example, based on the identification of model features, each model is determined to be a dental cast or non-dental cast. Optionally, dental casts are stored in a designated storage space S1, and non-dental casts are stored in a designated storage space S2. In step 304, at least two dental casts from the same order are grouped together. For example, a single sheet allows for up to eight dental casts; in this case, the eight dental casts can be grouped together. Step 304 improves subsequent sorting efficiency because multiple dental casts are grouped together and subsequently manufactured simultaneously. In step 306, at least one non-dental cast model from the same order is grouped together. For example, if order "A" from user "HEYGEARS" only has a single abutment, the single abutment is grouped together. In another example, at least two non-dental cast models from the same order are grouped together. For example, two abutments and three gingivae of order "A" of user "HEYGEARS" are grouped together.

[0045] In step 308 , at least one set of non-dental cast models and / or at least one set of dental cast models are laid out.

[0046] In one example, at least one set of non-dental models is laid out. For example, 10 sets of non-dental models are laid out, each set of non-dental models including 5 non-dental models. After laying out, the 10 sets of non-dental models occupy 2 frames.

[0047] In one example, at least one set of dental models is laid out. For example, four sets of dental models are laid out, each set of dental models including six dental models. After laying out, the four sets of dental models occupy two formats.

[0048] In one example, at least one set of non-dental models and at least one set of dental models are laid out. For example, 10 sets of dental models and 10 sets of non-dental models are laid out. After laying out, 9 sets of dental models occupy 3 frames, 8 sets of non-dental models occupy 4 frames, and 1 set of dental models and 2 sets of non-dental models jointly occupy 1 frame.

[0049] exist Figure 2 or Figure 3 In the flowchart shown, the number of models in each group is adjustable, for example, influenced by the print format size and the model attachment connection (i.e., the use of an attachment to connect two or more models). An attachment can be used to connect two or more models, such as using a base plate to connect multiple non-dental models (e.g., abutments), or using a base plate to connect an abutment and a dental cast, or using a base plate to connect a dental cast and another dental cast.

[0050] It is understood that typesetting or layout is inherently limited by the size of the format. Figure 4 A schematic diagram of a layout is shown. Multiple models 410 are arranged on a web 420, with each model spaced apart from the others. Models 410 are not allowed to extend beyond web 420. In other words, the projection of models 410 on web 420 is not allowed to intersect or be tangent to a boundary 422 of web 420.

[0051] In some embodiments, layout is performed based on the ratio of the total projected area to the breadth area of ​​at least one group of models. For example, a group of models (dental cast models or non-dental cast models) includes one model or a plurality of models spaced apart from each other. The projected area of ​​each model on any plane (e.g., breadth plane) can be determined, and the spacing between any two models can be set or determined, so that the total projected area of ​​this group of models can be determined. In some embodiments, when the ratio of the total projected area to the breadth area of ​​at least one group of models is 50% to 95% (e.g., 55% to 90%, e.g., 60% to 85%, e.g., 65% to 80%, e.g., 70% to 75%), the at least one group of models is arranged on the same breadth.

[0052] In some embodiments, layout is performed based on the ratio of the total occupied area to the breadth area of ​​at least one group of models. For example, a group of models (dental cast models or non-dental cast models) includes one model or a plurality of models spaced apart from each other. The projection pattern of each model on any plane (e.g., breadth plane) can be determined, and then the area (i.e., occupied area) of the occupied pattern (e.g., rectangle or circle) covering the projection pattern is determined based on the projection pattern. The spacing between any two models or occupied patterns can be set or determined, so that the total occupied area of ​​this group of models can be determined. In some embodiments, when the ratio of the total occupied area to the breadth area of ​​at least one group of models is 70% to 95% (e.g., 75% to 90%, e.g., 80% to 85%), the at least one group of models is arranged on the same breadth.

[0053] Figure 5 The footprint and frame area are shown. Figure 5 In the figure, two identical models are arranged on a format 510, and the projection area or projection pattern 520 of the model is an irregular shape. The projection area of ​​a single model is the surface area of ​​the projection area 520. The occupied area 540 surrounds the projection area of ​​the model, and the surface area of ​​the occupied area 540 is the occupied area.

[0054] It can be understood that additive manufacturing obtains the final object by continuously or intermittently building multiple physical layers. The greater the number of layers of an object, the longer it takes to obtain the final object. On a single sheet, if the height or number of layers of multiple models differs greatly, the overall time will be longer. For example, model A with 500 layers and model B with 200 layers are arranged on the same sheet. In the process of using material to build layers 1 to 200, both model A and model B are being formed. In the process of using material to build layers 201 to 500, only model A is formed (model B has been completed).

[0055] In some embodiments, the models are sorted based on the height of at least one group, and then arranged based on the ratio of the total projected area or the total occupied area to the format area.

[0056] In one example, a group of models includes only a single model, and the height of the model determines the height of the group. In other examples, a group of models includes multiple models, and the maximum height of the model among the multiple models determines the height of the group. After sorting based on the height of at least one group of models, the maximum height difference between two or more adjacent groups of models is intentionally reduced, thereby shortening the overall manufacturing time for all models.

[0057] In some embodiments, two or more models are connected in the height direction (ie, the direction perpendicular to the web). Figure 6 A model 620 and a plurality of models 640 are arranged on a format 610 , wherein the height of the model 620 is higher than the height of the model 640 , for example, 2 to 10 times. Figure 7 A schematic diagram of another typesetting is shown. A model 720 and multiple models 740 are arranged on a frame 710. Model 720 is taller than a single model 740. However, after at least two models 740 are connected, for example, by a support member 742, the total height of the connected or stacked models 740 is relatively close to the height of the models 720.

[0058] Figure 8A A typography showing a plurality of objects having sharp ends, Figure 8B Another arrangement of multiple objects with sharp ends is shown. Figure 8A As shown, a plurality of objects 820 with sharp ends (e.g., abutments or incisors) are arranged on a web 810, and the plurality of objects 820 have substantially the same height. Planes 850 and 860 are parallel to the web. The cross-sectional area of ​​the objects 820 on plane 850 is smaller than that on plane 860. If the cross-sectional area of ​​the plurality of objects 820 on plane 850 is too small, the risk of build failure due to stress concentration will increase. Figure 8BAs shown, a plurality of objects 820 having sharp ends are arranged on a web 810 , and the plurality of objects 820 have substantially the same height, but some of the objects 820 are equipped with supports to obtain increased height. Figure 8B The layout ensures that the cross-sectional areas of the multiple objects 820 in the plane 850 are not too small at the same time, thereby reducing the risk of the aforementioned construction failure.

[0059] In one example, three designers in different geographical locations successively created 20 3D models, including 6 dental models, 5 abutments, 4 figurines, and 5 industrial parts. After the design or creation was completed, the dental models and abutments in these 20 3D models were automatically stored in storage space D in the cloud. Specifically, the 6 dental models were stored in folder D1 of storage space D, and the 5 abutments were stored in folder D2 of storage space D. The figurines in these 20 3D models were automatically stored in storage space C in the cloud, and the industrial parts in these 20 3D models were automatically stored in storage space I in the cloud.

[0060] The dental production factory at location G1 continuously or simultaneously extracts 8 objects from the storage space D for layout (filling one layout), slices the layout objects, and then transmits the slice files to the light-curing printing device through a storage medium, the cloud or a server.

[0061] Afterward, the dental production factory at location G1 continuously or simultaneously extracts the three objects from storage space D for layout (but not fully layout). After waiting for, say, 3 hours, no more objects can be extracted from storage space D. The three layout objects are then sliced ​​directly. The sliced ​​files are then transferred via a storage medium, cloud, or server to a stereolithography device, where they are used to create dental models or abutments using, for example, photosensitive resin.

[0062] The toy factory at location G2 continuously or simultaneously extracts four objects from storage space C for layout (filling a layout), slices the layout objects, and then transmits the slice files to the FDM printing device through storage media, the cloud or a server, using PLA, ABS, etc. to manufacture figures.

[0063] The automobile factory at location G3 continuously or simultaneously extracts two objects from storage space 1 for layout (filling a single page), slices the laid-out objects, and then transmits the sliced ​​files to an SLS printer via a storage medium, the cloud, or a server. Thereafter, the automobile factory continuously or simultaneously extracts three objects from storage space 1 for layout (filling a single page due to their smaller size), slices the three laid-out objects, and then transmits the sliced ​​files to an SLS printer via a storage medium, the cloud, or a server to manufacture industrial parts using, for example, powder.

[0064] Based on the example above, a method for manufacturing an object using a three-dimensional model is provided, the method comprising: obtaining multiple three-dimensional models, the three-dimensional models including model association information; storing the multiple three-dimensional models in a first storage unit or a second storage unit based on the model association information; extracting at least one target three-dimensional model from the first storage unit or the second storage unit, and typeset the target three-dimensional model; and obtaining an object through additive manufacturing based on the typeset target three-dimensional model. After the design of multiple three-dimensional models is completed, the present application can classify and store the designed three-dimensional models, automatically capture data from the classified storage units, automatically complete pre-processing, and automatically send the data to a three-dimensional printing device for three-dimensional printing, without requiring any manual operation throughout the entire process, thereby improving the printing efficiency of the three-dimensional model.

[0065] In some embodiments, model-related information includes at least one of the following: product category, application type, material category, additive manufacturing equipment category, model file format, pre-processing parameters, and order information. Pre-processing parameters include, for example, whether to print hollow or solid, and whether to add labels. Order information includes, for example, order number, order date, delivery date, and process notes.

[0066] The product type is the product application field corresponding to the 3D model, for example, dentistry, orthopedics, headphones, action figures and other fields. The application type is a more specific application type under the product application field corresponding to the 3D model. For example, the dental product application field includes orthodontic applications, implant applications, maxillofacial applications, etc.

[0067] Material categories refer to the various substances required to construct three-dimensional objects during the 3D printing process. These materials have specific physical and chemical properties and can be precisely controlled by the 3D printer and stacked layer by layer according to the requirements of the three-dimensional model to eventually form a physical object with a specific shape and function. They include but are not limited to filamentary materials, powder materials, and liquid materials (mainly photosensitive resins, etc.).

[0068] Additive manufacturing equipment types refer to the type of 3D printing equipment used to create a 3D model, such as plastic 3D printing equipment, metal 3D printing equipment, ceramic 3D printing equipment, and biological 3D printing equipment. Alternatively, 3D printing equipment types can be categorized based on the principles used to create the 3D model, such as fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), and layered object manufacturing (LOM).

[0069] In some embodiments, based on model association information, multiple three-dimensional models are stored in a first storage unit or a second storage unit (for example, in the form of a folder), including: storing at least one three-dimensional model of a first product category among the multiple three-dimensional models in the first storage unit; and storing at least one three-dimensional model of a second product category among the multiple three-dimensional models in the second storage unit.

[0070] In some embodiments, multiple three-dimensional models are stored in a first storage unit or a second storage unit based on model association information, including: storing at least one three-dimensional model of the first product category and the first application type among the multiple three-dimensional models in the first storage unit; and storing at least one three-dimensional model of the first product category and the second application type among the multiple three-dimensional models in the second storage unit.

[0071] In some embodiments, based on model association information, multiple three-dimensional models are stored in a first storage unit or a second storage unit, including: storing at least one three-dimensional model of a first material among the multiple three-dimensional models in the first storage unit; and storing at least one three-dimensional model of a second material among the multiple three-dimensional models in the second storage unit.

[0072] In some embodiments, storing the plurality of three-dimensional models in the first storage unit or the second storage unit based on the model association information includes: storing at least one three-dimensional model suitable for the first additive manufacturing device among the plurality of three-dimensional models in the first storage unit; and storing at least one three-dimensional model suitable for the second additive manufacturing device among the plurality of three-dimensional models in the second storage unit. The terms "first additive manufacturing device" and "second additive manufacturing device" may refer to different types of devices, or to devices of the same type with different process parameters applied.

[0073] In some embodiments, before extracting at least one target three-dimensional model from the first storage unit or the second storage unit, the method also includes: detecting whether the three-dimensional model in the first storage unit or the second storage unit is abnormal; when an abnormal three-dimensional model is detected, generating an alarm message.

[0074] In some embodiments, detecting whether the three-dimensional model in the first storage unit or the second storage unit is abnormal includes: detecting whether the design format of the three-dimensional model in the designated storage unit is abnormal; and / or detecting whether the material used for the three-dimensional model in the designated storage unit is abnormal; and / or detecting whether the design content of the three-dimensional model in the designated storage unit is abnormal.

[0075] In some embodiments, typeset the target three-dimensional model, including: preprocessing the target three-dimensional model; and typeset the preprocessed target three-dimensional model.

[0076] In some embodiments, acquiring the multiple three-dimensional models includes: generating the multiple three-dimensional models continuously or simultaneously.

[0077] In some embodiments, extracting at least one target three-dimensional model from the first storage unit or the second storage unit and typeset the target three-dimensional model includes at least one of the following: continuously extracting the target three-dimensional model so that the extracted target three-dimensional model fills a single format; continuously extracting the target three-dimensional model within a predetermined time period and typeset the extracted target three-dimensional model.

[0078] For example, if each target 3D model can be arranged in N pages, it means that the N-1 pages are already full, and the target 3D models on the first N-1 pages can be subsequently processed. However, if the target 3D model in the Nth page is not full, it is necessary to wait for the next target 3D model and then try to arrange it until the Nth page is full.

[0079] On the other hand, if the area that does not fully fit the target 3D model exceeds a preset waiting time, typesetting can be directly triggered. The preset waiting time can be pre-set based on actual business needs, actual product requirements, or actual application scenarios. On the other hand, manual intervention can also be used to force typesetting of the area that does not fully fit the target 3D model.

[0080] In some embodiments, the aforementioned method further includes: in response to the expedited processing signal, immediately extracting the identification three-dimensional model from the first storage unit or the second storage unit, and typeset the identification three-dimensional model.

[0081] In some embodiments, extracting at least one target three-dimensional model from the first storage unit or the second storage unit and layout the target three-dimensional model includes: determining multiple target three-dimensional models belonging to the same order in the first storage unit or the second storage unit; and arranging the multiple target three-dimensional models belonging to the same order to be adjacent to each other.

[0082] In some embodiments, obtaining an object through additive manufacturing based on a typeset target three-dimensional model includes: slicing the typeset target three-dimensional model; and transferring the slice file to an additive manufacturing device.

[0083] A system for manufacturing objects using three-dimensional models is also provided, comprising: at least two storage units configured to store three-dimensional models; a first processor configured to obtain multiple three-dimensional models carrying model association information, and store the three-dimensional models in any storage unit based on the model association information; a second processor configured to extract at least one target three-dimensional model from the storage unit and typeset the extracted target three-dimensional model; and an additive manufacturing device configured to obtain the object through additive manufacturing based on the typeset target three-dimensional model.

[0084] In some embodiments, the first processor or the second processor is any one of the following: a local server, a cloud server, a mobile communication device, or a computer device.

[0085] The above embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
