Description

Technical Field

[0001] The present application relates to the technical field of additive manufacturing equipment, and more particularly to an additive manufacturing component integrated with subtractive machining, an additive manufacturing equipment and a three-dimensional object. Background Art

[0002] 3D printing is a new manufacturing process that has developed rapidly in recent years. The 3D printing process is mainly divided into two categories: selective laser melting technology (SLM) based on a powder bed and fused deposition modeling technology (FDM).

[0003] SLM uses a high-energy laser beam to melt metal powder to form three-dimensional parts in a layer-by-layer stacking manner. The SLM process is suitable for manufacturing high-precision and high-strength metal parts and is commonly used in fields such as aerospace, medical devices, and the automotive industry. FDM forms three-dimensional objects by melting thermoplastic materials and depositing them layer by layer through a nozzle. Due to its low equipment cost, simple operation, and rich material selection, the FDM technology is widely used in rapid prototyping, education, and the production of some functional components. However, both SLM and FDM technologies can manufacture complex internal structures, such as three-dimensional parts with internal channels.

[0004] Currently, although 3D printing technology can manufacture complex internal structures, after printing three-dimensional parts, the surfaces of these three-dimensional parts usually need to be further trimmed (for example, smoothed and / or cleaned). Some three-dimensional parts also have internal channels. Since trimming involves removing materials to reduce surface roughness, it is difficult to trim the surfaces of the internal channels of these three-dimensional parts, especially for those with complex internal structures and hard-to-reach internal channels. Traditional surface treatment methods often cannot effectively perform trimming.

[0005] Therefore, there is an urgent need for an additive manufacturing component integrated with subtractive machining that can provide layer-by-layer trimming for three-dimensional parts while the three-dimensional parts are being constructed layer by layer. Summary of the Utility Model

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of this application.

[0041] For ease of understanding, first, a brief introduction to two common types of additive manufacturing devices 1 will be given.

[0042] An additive manufacturing device 1 based on powder bed selective laser melting technology forms complex three-dimensional structures by gradually melting materials layer by layer using a high-energy beam. The materials are usually solid particulate powders, which are usually metal materials such as stainless steel, copper, titanium alloy, aluminum alloy, or non-metal materials such as ceramics, plastics, resins, and composite materials, to build three-dimensional objects.

[0043] Generally, the main components of an additive manufacturing device 1 based on powder bed selective laser melting technology include an optical path unit, a powder supply system, a powder spreading device, a forming chamber 10, a forming platform 11, and a control system, etc. In a specific spatial layout, the optical path unit can be arranged above the forming platform 11, or can be set based on the core application points taught in this application according to the actual structural design. In the control logic, the control system realizes the control of the optical path unit, the powder supply system, and the powder spreading device, that is, the control of this application is preferably realized by a computer control system. It should be understood that the control system is connected to the components of the additive manufacturing device 1 including the optical path unit, the powder supply system, and the powder spreading device, for monitoring and adjusting printing parameters, motion control, and sensor data to ensure the execution of the 3D printing process.

[0044] An additive manufacturing device 1 using fused deposition modeling technology forms complex three-dimensional structures by heating thermoplastic materials and extruding the molten materials through a nozzle. The materials are usually thermoplastic filament coils, and the materials are usually thermoplastic materials such as PLA, ABS, PETG, and TPU.

[0045] Generally, the main components of the additive manufacturing device 1 using the fused deposition modeling technology include a heating head, a material supply system, a forming platform 11, a motion system, and a control system. In a specific setting, the print head is at least composed of a heater and a nozzle. The material supply system feeds the material from the material roll into the print head by a wire feeding mechanism 12. The motion system usually adopts an X-Y-Z axis motion system. In the control logic, the control system realizes the control of the heating head, the material supply system, the forming platform 11, and the motion system. That is, the control of this application is preferably realized by a computer control system. It should be understood that the control system is connected to the components of the additive manufacturing device 1 including the heating head, the material supply system, the forming platform 11, and the motion system, and is used for monitoring and adjusting the printing parameters, motion control, and sensor data to ensure the execution of the 3D printing process.

[0046] Before 3D printing, the operator needs to use modeling software, such as computer-aided design CAD software, to create a three-dimensional object model. Then, the three-dimensional object model is processed by layer slicing to generate a series of two-dimensional slice files. Each two-dimensional slice file represents a layer to be printed, and corresponding layer slicing data is generated to describe the geometric shape and printing path of each layer. The control system can control the operation of each component of the additive manufacturing device 1 according to these layer slicing data to achieve selective sintering / fusion layer by layer to construct a complete three-dimensional object.

[0047] For the convenience of understanding, this application refers to the additive manufacturing device 1 using the fused deposition modeling technology. And for the convenience of 3D printing and finishing processing of three-dimensional objects, two sets of processing models are set. The specific models are modeled by the operator using existing modeling software according to actual needs. Exemplarily: create a three-dimensional printing model, and then process the three-dimensional printing model by layer slicing to generate a series of two-dimensional slice files. Each two-dimensional slice file represents a layer to be printed, and corresponding layer slicing data is generated to describe the geometric shape and printing path of each layer; create a three-dimensional finishing model, and then process the three-dimensional printing model by layer slicing to generate a series of two-dimensional slice files. Each two-dimensional slice file represents a printed layer, and corresponding layer finishing data is generated to describe the finishing path of each layer.

[0048] Thus, in some embodiments, referring to Figure 1 as shown, the additive manufacturing device 1 involved in this application, in addition to the above structures, further includes an additive manufacturing component 2 integrated with subtractive machining.

[0049] Among them, the additive manufacturing component 2 integrated with subtractive machining is arranged in the forming chamber 10 and is located at one end of the forming platform 11 in the forming chamber 10, and is used for providing layer-by-layer finishing for the three-dimensional object while constructing the three-dimensional object layer by layer.

[0050] In some embodiments, referring to Figure 2 As shown, the additive manufacturing component 2 for integrated subtractive manufacturing is at least composed of a motion part 20, a printing part 21, and a trimming part 22; the motion part 20 is arranged in the forming chamber 10 and is used to provide multi-axis movement; the printing part 21 is arranged at the printing end of the motion part 20 and is used to layer by layer construct a three-dimensional object on the forming platform 11; the trimming part 22 is arranged at the trimming end of the motion part 20 and is used to perform trimming processing on a preset layer of the three-dimensional object; wherein, the printing part 21 and the trimming part 22 adopt a rotary switching processing setting, that is, after the printing part 21 finishes printing, the motion part 20 rotates the printing part 21 and the trimming part 22 by a set angle, so as to switch to the trimming part 22 to perform trimming processing on the three-dimensional object.

[0051] Specifically, referring to Figure 3 and Figure 4 As shown, the motion part 20 includes a robotic arm 20-1 and a rotating unit 20-2. The robotic arm 20-1 is installed in the forming chamber 10 and is used to provide multi-axis movement; the rotating unit 20-2 is installed at the processing end of the robotic arm 20-1, and the printing part 21 is arranged at the printing end of the rotating unit 20-2 and is connected to the wire feeding mechanism 12 of the additive manufacturing device 1. The wire feeding mechanism 12 of the additive manufacturing device 1 guides the printing wire into the printing part 21; the trimming part 22 is arranged at the trimming end of the rotating unit 20-2, and the output end of the trimming part 22 is a tool; wherein, the printing part 21 and the trimming part 22 are symmetrically arranged with respect to the center line of the rotating unit 20-2; in order to facilitate the wiring of the printing part 21 and the trimming part 22, a wiring space with a preset size is formed between the printing part 21 and the trimming part 22; wherein, as long as the printing part 21 can perform 3D printing processing, it can be any form of printing structure. In this application, a printing structure composed of a print head and a heater is referred to; as long as the trimming part 22 can perform subtractive processing, it can be any form of cutting structure. In this application, a trimming structure composed of a tool fixture and a tool is referred to; wherein, as long as the rotating unit 20-2 can drive the printing part 21 and the trimming part 22 to rotate, it can be any form of rotating mechanism, including but not limited to a hollow rotating platform composed of a servo motor, a bearing, a gear, a transmission shaft, and a turntable, a rotating platform composed of a rotating cylinder and a platform, etc. In this application, a rotating platform composed of a servo motor and a platform is referred to.

[0052] Exemplarily, the robotic arm 20-1 can optionally adopt, for example, Figure 5As shown, it includes an installation base 20-10, a first arm segment 20-11, a second arm segment 20-12, and a third arm segment 20-13. The installation base 20-10 is arranged inside the forming chamber 10. The two ends of the first arm segment 20-11 are respectively movably connected to the installation action and the second arm segment 20-12. The two ends of the second arm segment 20-12 are respectively movably connected to the first arm segment 20-11 and the third arm segment 20-13. The two ends of the third arm segment 20-13 are respectively movably connected to the second arm segment 20-12 and the rotation unit 20-2. Among them, during the movement process, the first arm segment 20-11 drives the second arm segment 20-12 to move along the movement trajectory set by the operator, the second arm segment 20-12 drives the third arm segment 20-13 to move along the movement trajectory set by the operator, and the third arm segment 20-13 drives the rotation unit 20-2 to move along the movement trajectory set by the operator, so as to complete the movement of the robotic arm 20-1 driving the rotation unit 20-2 along the movement trajectory set by the operator. Among them, the driving of the robotic arm 20-1 is completed by the operator using the existing programming software supporting the existing robotic arm 20-1.

[0053] In the actual implementation process, when the rotation unit 20-2 rotates to the first preset angle, the rotation unit 20-2 aligns the printing part 21 with the forming platform 11, that is, makes the movement direction of the printing part 21 perpendicular to the plane where the forming platform 11 is located. When the rotation unit 20-2 rotates to the second preset angle, the rotation unit 20-2 aligns the trimming part 22 with the forming platform 11, that is, makes the movement direction of the trimming part 22 perpendicular to the plane where the forming platform 11 is located. Specifically, the first preset angle and the second preset angle are set by the operator according to actual needs. In this application, the first preset angle refers to 0°, and the second preset angle refers to 180°. That is, by rotating the rotation unit 20-2 to 0°, the movement direction of the printing part 21 is made perpendicular to the plane where the forming platform 11 is located. By rotating the rotation unit 20-2 to 180°, the movement direction of the trimming part 22 is made perpendicular to the plane where the forming platform 11 is located. Among them, whenever the rotation unit 20-2 makes a rotational movement, the robotic arm 20-1 moves the rotation unit 20-2 to a safe area, which in this application refers to an area that will not interfere with the forming platform 11 and the three-dimensional object.

[0054] In some embodiments, referring to Figures 2 - 6 As shown, the robotic arm 20-1 and the rotation unit 20-2 are arranged in the top area of the forming chamber 10, and the rotation unit 20-2 is located on one side of the forming platform 11, so as to facilitate the robotic arm 20-1 to drive the rotation unit 20-2 to drive the printing part 21 and the trimming part 22 to move to the forming area of the forming platform 11.

[0055] In some embodiments, referring to Figure 7 and Figure 8As shown, the robotic arm 20-1 and the rotating unit 20-2 are arranged in the bottom area of the forming chamber 10, and the rotating unit 20-2 is located on one side of the forming platform 11, so that the robotic arm 20-1 drives the rotating unit 20-2 to drive the printing part 21 and the trimming part 22 to move to the forming area of the forming platform 11.

[0056] In the actual implementation process, after the printing part 21 and the trimming part 22 are integrated into the rotating unit 20-2, refer to Figure 1 As shown, at least one side of the forming chamber 10 is provided with a chamber door to facilitate the operator to open, take, or place items; and after the robotic arm 20-1 and the rotating unit 20-2 are arranged in the bottom area of the forming chamber 10, a switch door is provided at the top of the forming chamber 10 to facilitate the operator to open, take, or add required items, and the operator can also open the switch door to check the 3D object printing or trimming situation in the forming chamber 10.

[0057] Thus, the process of printing and trimming in one embodiment of the present application is as follows:

[0058] When performing 3D printing, the rotating unit 20-2 rotates to the first preset angle to make the moving direction of the printing part 21 perpendicular to the plane where the forming platform 11 is located. Then, the robotic arm 20-1 drives the rotating unit 20-2 to move towards the forming area of the forming platform 11. After the printing part 21 moves to the set printing starting point in the forming area, through the cooperation of the robotic arm 20-1 and the printing part 21, a three-dimensional object is constructed; after the preset layer of the three-dimensional object is constructed, the robotic arm 20-1 drives the rotating unit 20-2 to move to the safe area. Then, the rotating unit 20-2 rotates to the second preset angle to make the moving direction of the trimming part 22 perpendicular to the plane where the forming platform 11 is located. Then, the robotic arm 20-1 drives the rotating unit 20-2 to move towards the forming area of the forming platform 11. After the trimming part 22 moves to the set trimming starting point in the forming area, through the cooperation of the robotic arm 20-1 and the trimming part 22, the cutting and trimming process of the preset layer of the three-dimensional object is carried out; after the preset layer of the three-dimensional object is trimmed, the robotic arm 20-1 drives the rotating unit 20-2 to move to the safe area. Then, the rotating unit 20-2 rotates to the first preset angle to make the moving direction of the printing part 21 perpendicular to the plane where the forming platform 11 is located. Then, the robotic arm 20-1 drives the rotating unit 20-2 to move towards the forming area of the forming platform 11 for the next layer of printing; and so on, repeating the printing and corresponding trimming of the three-dimensional object layers until the three-dimensional object is formed; among them, the preset layer is set by the operator according to actual needs. When trimming is required for a certain layer, the trimming parameters matching this layer are called up to provide the trimming part 22 for trimming the corresponding layer.

[0059] In some embodiments, refer to Figure 9As shown, the forming chamber 10 of the present application adopts a layered design, and the two layers of the forming chamber 10 are respectively set as an additive manufacturing area 100 and a subtractive manufacturing area 101.

[0060] Thus, in some embodiments, referring to Figures 10 - 11 As shown, the moving part 20 further includes a three-axis robot 20-3 and a reciprocating motion unit 20-4. The three-axis robot 20-3 is arranged in the additive manufacturing area 100 of the forming chamber 10 and is used to provide movements in the X-axis, Y-axis, and Z-axis directions; the reciprocating motion unit 20-4 is arranged in the forming chamber 10, and the driving end of the reciprocating motion unit 20-4 is connected to the forming platform 11 and is used to drive the forming platform 11 to reciprocate between the additive manufacturing area 100 and the subtractive manufacturing area 101 of the forming chamber 10; wherein, the robotic arm 20-1 is arranged in the subtractive manufacturing area 101 of the forming chamber 10.

[0061] In the actual implementation process, referring to Figures 12 - 14 As shown, the three-axis robot 20-3 can adopt a structure including a first moving unit 230, a second moving unit 231, and a third moving unit 232. Exemplarily: the first moving unit 230 adopts a first driving member 230-1 and a transmission belt 230-2, the second moving unit 231 adopts a transmission wheel 231-1 and a first moving member 231-2, and the third moving unit 232 adopts a second moving member 232-1 and a second driving member 232-2; wherein, the transmission belt 230-2 is respectively connected to the first driving member 230-1 and the transmission wheel 231-1, the transmission wheel 231-1 is connected to the first moving member 231-2, the second moving member 232-1 is connected to the transmission belt 230-2 located in the first moving member 231-2, and the second driving member 232-2 is respectively connected to the second moving member 232-1 and the printing part 21; wherein, as long as the first driving member 230-1 can drive the transmission belt 230-2 to move, it can be any form of driving structure, and in the present application, a servo motor group is referred to; as long as the second driving member 232-2 can drive the printing part 21 to perform Z-axis movement, it can be any form of driving structure, and in the present application, a driving mechanism in which a servo motor is matched with a worm and worm gear is referred to.

[0062] Thus, the driving process of the three-axis robot 20-3 is: the first driving member 230-1 drives the transmission belt 230-2 to move, drives the transmission wheel 231-1 to rotate synchronously through the transmission belt 230-2, and then drives the first moving member 231-2 to perform Y-axis movement and drives the second moving member 232-1 to perform X-axis movement through the transmission wheel 231-1. At the same time, the second moving member 232-1 drives the second driving member 232-2 and the printing part 21 to move synchronously, and the second driving member 232-2 drives the printing part 21 to perform Z-axis movement.

[0063] In the actual implementation process, referring toFigure 11 , Figure 15 and Figure 16 As shown in Figure 11 , Figure 15 and Figure 16 , the reciprocating motion unit 20-4 includes a mounting base 240, a driving motor 241 and a linear moving member 242. The mounting base 240 is disposed in the forming chamber 10, and at least a part of one end of the mounting base 240 is located in the additive manufacturing area 100 of the forming chamber 10, and at least a part of the other end of the mounting base 240 is located in the subtractive manufacturing area 101 of the forming chamber 10. A track group is provided on the mounting base 240, and the forming platform 11 is connected to the track group of the mounting base 240 through a mounted moving slide. The driving motor 241 is installed in the mounting base 240, and the linear moving member 242 is connected to the driving end of the driving motor 241. And the linear moving member 242 can be any form of moving structure as long as it can perform linear reciprocating motion. In this application, reference is made to the ball screw 242-1 structure composed of a lead screw 242-1, a moving nut 242-2 and balls. Among them, the moving nut 242-2 of the ball screw 242-1 structure is connected to the forming platform 11.

[0064] During the actual implementation process, when the forming chamber 10 adopts a layered design, referring to Figure 9 As shown in Figure 9 , at least one side of the forming chamber 10 is provided with a first door corresponding to the additive manufacturing area 100 and a second door corresponding to the subtractive manufacturing area 101, so as to facilitate the operator to open, take, place or put items. And when the robotic arm 20-1 is disposed in the bottom area of the forming chamber 10, a switch door is provided at the top of the forming chamber 10, so as to facilitate the operator to open, take, place or add required items. And the operator can also view the three-dimensional object printing or trimming situation in the forming chamber 10 by opening the switch door.

[0065] Therefore, the driving process of the reciprocating moving unit is as follows: the driving motor 241 drives the linear moving member 242 to move, and the forming platform 11 is driven by the linear moving member 242 to reciprocate between the additive manufacturing area 100 and the subtractive manufacturing area 101 of the forming chamber 10 along the track group.

[0066] Therefore, the printing and trimming process of one embodiment of this application is as follows:

[0067] When performing 3D printing, the driving motor 241 drives the linear moving member 242 to move. The linear moving member 242 drives the forming platform 11 to move along the track group into the additive manufacturing area 100 of the forming chamber 10. Then, through the cooperation of the first moving unit 230, the second moving unit 231, and the third moving unit 232 of the three-axis robot 20-3, the printing part 21 is moved to the printing starting point set in the forming area. Then, through the cooperation of the first moving unit 230, the second moving unit 231, and the third moving unit 232, the three-dimensional object is constructed using the printing part 21. After the construction of the preset layer of the three-dimensional object is completed, the driving motor 241 drives the linear moving member 242 to move. The linear moving member 242 drives the forming platform 11 to move along the track group into the subtractive manufacturing area 101 of the forming chamber 10. Then, the manipulator 20-1 drives the trimming part 22 to move to the trimming starting point set in the forming area. Then, through the cooperation of the manipulator 20-1 and the trimming part 22, the cutting and trimming process of the preset layer of the three-dimensional object is carried out. After the trimming of the preset layer of the three-dimensional object is completed, the manipulator 20-1 drives the trimming part 22 to move to the safe area. Then, the driving motor 241 drives the linear moving member 242 to move.
