However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0054] At present, the mainstream 3D printing technologies for silicone products are material extrusion molding technology and photopolymerization curing technology. Extrusion molding technology is limited by the curing speed of silicone, resulting in low printing efficiency. Photopolymerization curing technology adds photosensitive polymers to silicone, which trigger cross-linking reactions and promote silicone curing through ultraviolet or infrared irradiation. In addition, the photosensitive polymers in photopolymerization curing technology and a series of subsequent reactions limit product applications and pose safety risks.

[0055] Therefore, the embodiment of the present application provides an ultrasonic silicone printing system to solve the problem in the prior art of how to promote silicone curing and improve printing efficiency while ensuring material safety. The present application also relates to an ultrasonic silicone printing method.

[0056] The present application is described in detail below through specific embodiments and drawings.

[0057] The present application embodiment provides an ultrasonic silicone printing system. Figure 1 The ultrasonic silicone printing system is described in detail. Figure 1 It is a schematic framework diagram of an ultrasonic silicone printing system provided in an embodiment of the present application.

[0058] In this embodiment, the ultrasonic silicone printing system includes an ultrasonic printing module, a silicone supply module and a data processing module; wherein the silicone supply module is used to store and provide corresponding metered silicone materials. The data processing module is used to obtain data information of the object to be printed, generate corresponding printing data according to the data information, and send the printing data to the ultrasonic printing module. The ultrasonic printing module serves as a heat source, and can form at least one printing focus point on the silicone material through the generated ultrasonic wave. The ultrasonic printing module receives the printing data, and controls the printing focus point according to the printing data to heat and solidify the silicone material to form the target object.

[0059] In this embodiment, the silica gel material is a silica gel material containing fluoride, and the silica gel material further contains component A and component B. Of course, in other examples, the silica gel material may only contain silica gel components.

[0060] In this embodiment, the silicone supply module includes a silicone containing tank, a silicone storage device and a control device, and the control device includes a microprocessor. The silicone containing tank is used to contain silicone, and the silicone containing tank is provided with a substrate, and the substrate can allow ultrasound to pass through and then perform ultrasonic printing on the silicone material. The silicone storage device is used to store silicone and provide silicone to the silicone containing tank. The silicone containing tank and the silicone storage device are connected through a conveying pipeline. The microprocessor is connected to the data processing module for communication, and is used to obtain the printing data of the data processing module, and control the silicone storage device to convey the corresponding metered silicone according to the printing data. A flow meter is provided in the silicone storage device for controlling the flow of silicone, so that the silicone can be replenished while avoiding the waste of silicone material.

[0061] In this embodiment, the data processing module is used to obtain data information of the object to be printed, and generate corresponding printing data according to the data information. Figure 2 As shown, Figure 2 1 is a flow chart of a method for generating printing data provided by an embodiment of the present application. Generating corresponding printing data according to data information includes the following steps:

[0062] Step S201: Analyze and model the data information of the object to be printed to obtain 3D shape data of the object to be printed.

[0063] In this step, the object to be printed includes a silicone object to be printed, that is, the object is made of silicone material. Each object to be printed has its own morphological structure. In this regard, the data information of the object to be printed can be analyzed to obtain morphological feature data corresponding to the object to be printed. Morphological feature data refers to the shape structure of the object to be printed and the corresponding coordinate position of each shape structure in three-dimensional space. The morphological feature data can fully reflect the three-dimensional morphological structure of the object to be printed. Specifically, in one example, the data information of the object to be printed includes image data of the object to be printed, and the image data of the object to be printed can be subjected to image recognition analysis to obtain morphological feature data corresponding to the object to be printed. In another example, the object to be printed can be directly physically scanned to obtain scan data, and the scan data has a one-to-one correspondence with the physical data of the object to be printed, and then the obtained scan data can be converted into morphological feature data of the object to be printed.

[0064] Then, the morphological feature data is processed by data model to obtain standard model data associated with the object to be printed. In this step, the data model processing of the morphological feature data mainly adopts a linear normalization processing method so that the morphological feature data can reach the standard model data that can be processed by the preset model.

[0065] Finally, a preset model is obtained, and the standard model data is input into the preset model to obtain 3D morphological data for the object to be printed. Specifically, in this step, the preset model is obtained by pre-training, that is, the standard model data of the above-mentioned morphological feature data is obtained, and the standard model data is used as a sample for training, which can be called a standard model data sample. An initial model is constructed, the parameters of the initial model are set, and the standard model data sample is input into the initial model. The initial model is iteratively trained with a large number of standard model data samples, and the output result of the initial model is compared with the preset standard 3D morphological data. If the comparison result is consistent, the initial model is determined as the preset model; if the comparison result is inconsistent, the standard model data sample is continuously input into the initial model for iterative training until the output result is consistent with the preset standard 3D morphological data. Then, after obtaining the preset model, the standard model data is input into the preset model to obtain the 3D morphological data for the object to be printed.

[0066] Step S202: Acquire feature information of a feature block of 3D morphological data of the object to be printed.

[0067] After obtaining the 3D shape data of the object to be printed, feature information of a feature block of the 3D shape data of the object to be printed is obtained, wherein the feature block of the 3D shape data of the object to be printed is a block of different regions formed by cutting the 3D shape of the object to be printed.

[0068] Acquiring feature information of a feature block of the 3D morphological data of the object to be printed includes: first, obtaining spatial coordinate information of feature points according to the 3D morphological data of the object to be printed, the 3D morphology of the object to be printed is composed of a plurality of feature points, and the feature points can constitute the 3D morphology of the object to be printed, so that each feature point corresponds to a spatial coordinate information in the spatial coordinate system. Then, determining feature lines in different dimensional directions according to the spatial coordinate information of the feature points, and connecting feature points in one dimensional direction to form a line according to the principle that a plurality of points can constitute a line. In one example, in order to determine whether each feature point can constitute a line, it is necessary to determine the spatial coordinates of each feature point, so that the spatial position of each feature point can be determined. In addition, based on the large number of feature points and the fact that they are distributed in different dimensional directions, feature lines in different dimensional directions can be determined according to the spatial coordinate information of the feature points. Then, forming a plurality of feature surfaces constituting the 3D morphology of the object to be printed according to the feature lines in different dimensional directions, and forming a plurality of feature surfaces constituting the 3D morphology of the object to be printed according to the principle that a plurality of lines can constitute a surface, the feature lines in different dimensional directions can be used to form a plurality of feature surfaces constituting the 3D morphology of the object to be printed. Finally, the contour morphology information of each feature surface is obtained, and the feature information of the feature block is generated according to the contour morphology information of each feature surface. In this step, the feature block is a three-dimensional structure, and the feature block can be formed by overlapping multiple feature surfaces. The features of the feature block can be constructed according to the contour morphology of each feature surface.

[0069] Step S203: Generate corresponding printing data according to the feature information of the feature block.

[0070] After obtaining the feature information corresponding to several feature blocks, the corresponding printing data is generated according to the information of several feature blocks. Specifically, since the object to be printed can be composed of multiple feature blocks, in order to clarify each feature block, each feature block is encoded to form a coded feature block with coding information. For example, the first coded feature block is coded feature block 1, the second coded feature block is coded feature block 2, the third coded feature block is coded feature block 3... and so on. Then, according to the coding information of the coded feature block, a printing feature block that can be stacked in sequence is constructed. The printing feature block refers to a feature block that can be used for printing. By printing each feature block, the printing data of the object to be printed is constructed, and the printing of the object to be printed is realized by printing the data to form the target object. In this embodiment, the object to be printed is generally a three-dimensional object, such as an orthodontic appliance. When printing the three-dimensional object to be printed, the corresponding feature blocks need to be printed in a specified printing order. Then, when determining the printing data, the coded feature block with coding information is given the printing order of the feature block, but it is necessary to further stack all the feature blocks in sequence to form a completed three-dimensional object. Therefore, this step needs to construct printing feature blocks that can be sequentially overlapped according to the coding information of the coding feature blocks. Then, the morphological information of each printing feature block and the spatial coordinate information corresponding to the morphology of the printing feature block are obtained, and the corresponding printing data is generated according to the morphological information of the printing feature block and the spatial coordinate information corresponding to the morphology of each printing feature block.

[0071] In this embodiment, since ultrasound can generate high energy, the temperature of ultrasound may change during continuous printing, thus affecting the printing result. In this regard, the data processing module is also used to obtain material temperature information of the printing area corresponding to the printing focus point and frequency information corresponding to the printing focus point, and generate corresponding printing data according to the material temperature information of the printing area corresponding to the printing focus point and the frequency information corresponding to the printing focus point.

[0072] Specifically, first, the material temperature information of the printing area corresponding to the next adjacent printing focus point and the frequency information corresponding to the current printing focus point are obtained. Then, according to the material temperature information of the printing area corresponding to the next adjacent printing focus point and the frequency information corresponding to the current printing focus point, the frequency information and preheating temperature information corresponding to the next printing focus point are obtained. Finally, the corresponding printing data is generated according to the frequency information and preheating temperature information corresponding to the next printing focus point.

[0073] After obtaining the printing data, the printing data is sent to the ultrasonic printing module. The ultrasonic printing module acts as a heat source and can form a printing focus on the silicone material by generating ultrasonic waves. The printing focus is controlled according to the printing data to heat and cure the silicone material to form a target object.

[0074] Specifically, in this embodiment, Figure 3 As shown, Figure 3 The present invention provides a flow chart of controlling the printing focus point according to the printing data to heat and solidify the silicone material to form a target object. Controlling the printing focus point according to the printing data to heat and solidify the silicone material to form a target object includes the following steps:

[0075] Step S301: Determine at least one base point printing position for the silicone material.

[0076] In this step, when printing the silicone material, it is necessary to determine the base point printing position for the silicone material, where the base point printing position is a reference point of the silicone material. The base point printing position can be set to at least one.

[0077] Step S302: focusing at least one printing focus point on the silicone material according to the base point printing position.

[0078] The printing focus is formed by ultrasound, and ultrasound can generate at least one printing focus. The printing focus has high energy and can heat and solidify the silicone material. In this step, at least one printing focus is focused on the silicone material according to the base point printing position.

[0079] In one example, determining at least one base point printing position for a silicone material includes two base point printing positions, the two base point printing positions are called a first base point printing position and a second base point printing position, and correspondingly, focusing at least one of the printing focal points on the silicone material according to the base point printing positions includes: first, obtaining a preliminary form for the silicone material. In this example, the preliminary form of the silicone material should correspond to the form of the target object, and mainly the volume of the silicone material in a three-dimensional state meets the printing volume requirement of the target object. Then, according to the preliminary form of the silicone material, any position on the outer surface of the preliminary form of the silicone material is determined as the first base point printing position, and any position inside the preliminary form of the silicone material is determined as the second base point printing position. In this example, the silicone material is preferably printed in an internal and external synchronous printing manner. Of course, in other examples, the first base point printing position and the second base point printing position are at other positions of the preliminary form of the silicone material. Then, according to the preliminary form of the silicone material and the first base point printing position, the first wavelength and the first frequency of the printing focal point are determined, and according to the preliminary form of the silicone material and the second base point printing position, the second wavelength and the second frequency of the printing focal point are determined. Finally, a first printing focal point is focused on the silicone material according to the first base point printing position, the first wavelength and the first frequency, and a second printing focal point is focused on the silicone material according to the second base point printing position, the second wavelength and the second frequency.

[0080] In one example, determining that at least one base point printing position for a silicone material includes a base point printing position, and focusing the printing focal point on the silicone material according to the base point printing position includes: first, obtaining a preliminary morphology for the silicone material, and determining any position on the outer surface or any position inside the preliminary morphology of the silicone material as a base point printing position according to the preliminary morphology of the silicone material. Then, determining a first wavelength and a first frequency for constructing a printing focal point according to the preliminary morphology of the silicone material and the base point printing position, and focusing the printing focal point on the silicone material according to the base point printing position, the first wavelength, and the first frequency.

[0081] Step S303: heating and curing the silicone material according to the printing focus and the printing data to form a target object.

[0082] After focusing a printing focus on the silicone material, the silicone material is heated and cured according to the printing focus and printing data to form a target object.

[0083] Specifically, corresponding to the first printing focal point and the second printing focal point, the silicone material is heated and cured according to the printing focal point and the printing data to form the target object, including: first, according to the printing data, the first printing focal point and the second printing focal point are determined to be respectively relative to the first printing track and the second printing track of the silicone material. The first printing focal point is printed along the first printing track, and the second printing focal point is printed along the second printing track. Then, the first frequency of the first printing focal point at each spatial coordinate position in the first printing track, and the second frequency of the second printing focal point at each spatial coordinate position in the second printing track are determined. Among them, the first frequency can be the same frequency or different frequencies at different spatial coordinate positions. The second frequency can be the same frequency or different frequencies at different spatial coordinate positions. Finally, according to the first printing track and the first frequency, the second printing track and the second frequency, the silicone material is heated and cured to form the target object.

[0084] In one example, corresponding to a first printing focal point, a silicone material is heated and cured according to the printing focal point and printing data to form a target object, including: first, a first printing trajectory of the first printing focal point relative to the silicone material is determined according to the printing data. The first printing focal point is printed along the first printing trajectory. Then, a first frequency of the first printing focal point in each spatial coordinate position in the first printing trajectory is determined, and the first frequency can be the same frequency or different frequencies at different spatial coordinate positions. Finally, the silicone material is heated and cured according to the first printing trajectory and the first frequency, and the second printing trajectory and the second frequency to form the target object.

[0086] The embodiment of the present application provides a corresponding amount of silicone material through a silicone supply module, so that the silicone material can meet the printing requirements while avoiding silicone waste. The data processing module generates corresponding printing data according to the data information of the object to be printed, and sends the printing data to the ultrasonic printing module. The ultrasonic printing module acts as a heat source, and can form at least one printing focus point on the silicone material through the generated ultrasonic wave, and control the printing focus point according to the printing data to heat and cure the silicone material to form a target object. The printing focus point formed by the ultrasonic wave can achieve improved curing, and is dynamically optimized and adjusted in combination with the light source and the material extrusion amount to improve accuracy and efficiency. Ultrasonic waves serve as an energy source to promote the curing of silicone without destroying the safety of silicone.

[0087] An embodiment of the present application also provides an ultrasonic silicone printing method, which is applied to the ultrasonic silicone printing system described above, and the ultrasonic printing module in the ultrasonic silicone printing system serves as a heat source. Figure 4 : is a flow chart of an ultrasonic silicone printing method provided in an embodiment of the present application. The method comprises the following steps:

[0088] Step S401: Control the silicone supply module to store and provide silicone material in corresponding quantities.

[0089] In this embodiment, the silicone supply module includes a silicone containing tank, a silicone storage device and a control device, and the control device includes a microprocessor.

[0090] In this embodiment, the silica gel material is a silica gel material containing fluoride, and the silica gel material further contains component A and component B. Of course, in other examples, the silica gel material may only contain silica gel components.

[0091] Step S402: Control the data processing module to obtain data information of the object to be printed, generate corresponding printing data according to the data information, and send the printing data to the ultrasonic printing module.

[0092] In this step, the object to be printed includes at least an appliance. The specific content of this step can be found in the description of the above embodiment, and will not be repeated here.

[0093] Step S403: Control the ultrasonic wave of the ultrasonic printing module to form at least one printing focus point on the silicone material; and control the printing focus point to heat and solidify the silicone material according to the received printing data to form a target object.

[0094] Specifically, first, at least one base point printing position for the silicone material is determined.

[0095] In this step, when printing the silicone material, it is necessary to determine the base point printing position for the silicone material, where the base point printing position is a reference point of the silicone material. The base point printing position can be set to at least one.

[0096] Then, at least one printing focus point is focused on the silicone material according to the base point printing position.

[0097] The printing focus is formed by ultrasound, and ultrasound can generate at least one printing focus. The printing focus has high energy and can heat and solidify the silicone material. In this step, at least one printing focus is focused on the silicone material according to the base point printing position.

[0098] In one example, it is determined that at least one base point printing position for the silicone material is two, and the two base point printing positions are called the first base point printing position and the second base point printing position. Correspondingly, focusing at least one of the printing focal points on the silicone material according to the base point printing position includes: first, obtaining the preliminary form of the silicone material. In this example, the preliminary form of the silicone material should correspond to the form of the target object, and mainly the volume of the silicone material in a three-dimensional state meets the printing volume requirement of the target object. Then, according to the preliminary form of the silicone material, any position on the outer surface of the preliminary form of the silicone material is determined as the first base point printing position, and any position inside the preliminary form of the silicone material is determined as the second base point printing position. In this example, the silicone material is preferably printed in an internal and external synchronous printing manner. Of course, in other examples, the first base point printing position and the second base point printing position are at other positions of the preliminary form of the silicone material. Then, according to the preliminary form of the silicone material and the first base point printing position, the first wavelength and the first frequency of the printing focal point are determined, and according to the preliminary form of the silicone material and the second base point printing position, the second wavelength and the second frequency of the printing focal point are determined.

Then, a first wavelength and a first frequency for constructing a printing focal point are determined according to the preliminary morphology of the silicone material and the base point printing position, and the printing focal point is focused on the silicone material according to the base point printing position, the first wavelength, and the first frequency.

[0100] Finally, the silicone material is heated and cured according to the printing focus and the printing data to form a target object.

[0101] After focusing a printing focus on the silicone material, the silicone material is heated and cured according to the printing focus and printing data to form a target object.

[0102] Specifically, corresponding to the first printing focal point and the second printing focal point, the silicone material is heated and cured according to the printing focal point and the printing data to form the target object, including: first, according to the printing data, the first printing focal point and the second printing focal point are determined to be respectively relative to the first printing track and the second printing track of the silicone material. The first printing focal point is printed along the first printing track, and the second printing focal point is printed along the second printing track. Then, the first frequency of the first printing focal point at each spatial coordinate position in the first printing track, and the second frequency of the second printing focal point at each spatial coordinate position in the second printing track are determined. Among them, the first frequency can be the same frequency or different frequencies at different spatial coordinate positions. The second frequency can be the same frequency or different frequencies at different spatial coordinate positions. Finally, according to the first printing track and the first frequency, the second printing track and the second frequency, the silicone material is heated and cured to form the target object.

[0103] In one example, corresponding to a first printing focal point, a silicone material is heated and cured according to the printing focal point and printing data to form a target object, including: first, a first printing trajectory of the first printing focal point relative to the silicone material is determined according to the printing data. The first printing focal point is printed along the first printing trajectory. Then, a first frequency of the first printing focal point in each spatial coordinate position in the first printing trajectory is determined, and the first frequency can be the same frequency or different frequencies at different spatial coordinate positions. Finally, the silicone material is heated and cured according to the first printing trajectory and the first frequency, and the second printing trajectory and the second frequency to form the target object.
