[0071] 3D printing is an additive manufacturing technology that builds three-dimensional objects by depositing materials layer by layer. The machine preparation process is a crucial initial step in ensuring the smooth execution of printing tasks. It plays a key role in ensuring the smooth progress of the printing process, improving printing efficiency, and improving the quality of the finished product.

[0072] In existing technology, the build cylinder position adjustment during 3D printer preparation relies primarily on manual operation. Operators must manually adjust the build cylinder, for example by turning a handwheel or pressing a button, until it is precisely positioned at the 3D printer's print start position.

[0073] However, this operation method that relies on manual experience has obvious disadvantages: on the one hand, the operation accuracy is greatly affected by human factors. Since it relies on the personal experience of the operator, the operation levels of different people are uneven, which is prone to positioning errors, thereby affecting the uniformity of the first layer of powder laying and the melting effect, resulting in unstable printing quality and affecting the final printing effect; on the other hand, the machine preparation process is cumbersome and time-consuming. It takes a long time from the beginning of preparation to the official start of printing, which undoubtedly reduces the overall printing efficiency of the 3D printer and is not conducive to achieving efficient and continuous production.

[0074] Based on this, the present application proposes a 3D printer preparation device and method, which can be used in the field of 3D printing equipment technology and aims to solve the above-mentioned technical problems of the prior art. Through standardized and intelligent operating procedures, the preparation process effectively reduces the dependence of the operator on experience, improves the accuracy and consistency of the positioning of the build cylinder, and significantly shortens the time period from the preparation stage to the actual start of printing, ultimately improving the printing efficiency and print quality of the 3D printer.

[0075] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0076] To facilitate understanding of the technical solution of this application, the structure of a 3D printer preparation device provided in an embodiment of this application is first introduced. It should be noted that in the embodiments of this application, unless otherwise specified, fixed connection can refer to connection by bolting, welding, riveting, or threading.

[0077] Figure 1 This is a schematic diagram of a 3D printer preparation device provided in an embodiment of the present application. Figure 1 As shown, the 3D printer includes a 3D printing body 100 and a base plate 200 arranged at the bottom of the 3D printing body 100, and the machine preparation device for the 3D printer includes: a guide rail assembly 1, a forming cylinder assembly 2, a plurality of positioning cylinders 3, a leveling assembly 4 and a control assembly 5.

[0078] Among them, the guide rail assembly 1 is fixedly arranged directly below the 3D printing body 100 and is parallel to the base plate 200. The forming cylinder assembly 2 is slidably arranged on the guide rail assembly 1, and the guide rail assembly 1 is used to drive the forming cylinder assembly 2 to switch between the printing position and the upper position. Multiple positioning cylinders 3 are fixedly installed on one side of the guide rail assembly 1, and the multiple positioning cylinders 3 are used to fix the forming cylinder assembly 2 at the printing position. The leveling assembly 4 is fixedly arranged below the guide rail assembly 1, and the leveling assembly 4 is used to level the base plate so that the printing plane remains overall horizontal. The guide rail assembly 1, the positioning cylinder 3 and the leveling assembly 4 are all data-connected to the control assembly 5.

[0079] In the embodiment of the present application, the 3D printer can be a commonly used 3D printing device. The 3D printing body 100 can include components such as a print head and a heating platform.

[0080] The base plate 200 is the basic support surface for 3D printing and can be used to fix the printing platform and the forming cylinder assembly 2 .

[0081] The guide rail assembly 1 can adopt a high-precision linear guide rail, specifically a structure combining a linear guide rail and a slider, and can be driven by a servo motor, a sliding drive motor or a stepping motor.

[0082] Furthermore, in the embodiment of the present application, the machine preparation device for the 3D printer can also detect the specific position of the forming cylinder assembly 2 slidingly set on the guide rail assembly 1 in real time through a position sensor.

[0083] The guide rail assembly 1 can be fixedly connected to the bottom of the 3D printing body 100 by bolts and is parallel to the base plate 200.

[0084] The forming cylinder assembly 2 refers to a movable printing table including a building forming area. The forming cylinder assembly 2 can be slidably connected to the guide rail assembly 1 through a slider assembly and can slide along the guide rail.

[0085] The guide rail assembly 1 can carry and guide the forming cylinder assembly 2 to move between different positions, for example, driving the forming cylinder assembly 2 to move between the printing position and the upper position.

[0086] Specifically, the guide rail assembly 1 may include a guide rail bracket, two guide rails arranged in parallel on the guide rail bracket, a slider slidingly connected to the guide rails, a sliding drive motor fixedly mounted on the guide rail bracket, a lead screw fixedly connected to the power output end of the sliding drive motor, and a sliding transmission block matched with the lead screw thread, and the sliding transmission block is fixedly connected to the bottom surface of the forming cylinder assembly 2 by bolts.

[0087] In one possible implementation, the sliding drive motor in the guide rail assembly 1 is electrically connected to the control assembly 5. When the control assembly 5 executes the automatic machine loading command, the control assembly 5 controls the sliding drive motor to rotate the lead screw, thereby driving the sliding transmission block to move along the guide rail, thereby driving the build cylinder assembly 2 and the slider to slide on the guide rail until the build cylinder assembly 2 is directly below the 3D printer body.

[0088] Multiple positioning cylinders 3 are bolted to the sides of the guide rail assembly 1. Specifically, there can be four positioning cylinders 3, which are used to lock the build cylinder assembly 2 at the printing position to ensure that the build cylinder assembly 2 does not shift during the printing process. The positioning cylinders 3 are digitally connected to the control assembly 5, and their specific operations are controlled by the control assembly 5. Air circuit control can be achieved through solenoid valves.

[0089] The leveling assembly 4 can be bolted to the underside of the guide rail assembly 1 and automatically level the substrate 200 to ensure the horizontality of the printing surface and improve print quality. Specific leveling methods can include electric lifting columns, pneumatic actuators, or servo motor linkages, and are not specifically limited here.

[0090] Furthermore, the leveling component 4 can be integrated with a high-precision level sensor and be data-connected with the control component 5 .

[0091] In the embodiment of the present application, the data connection can be an electrical connection, which can be implemented through a flat cable, a terminal cable or an industrial bus.

[0092] The control component 5 can coordinate the actions of each component in a timely manner by establishing a wired connection of electrical signals with the guide rail component 1, the positioning cylinder 3, and the leveling component 4, thereby controlling the coordinated operation of the entire machine preparation device.

[0093] In an embodiment of the present application, a working process of a device for preparing a 3D printer includes:

[0094] Initially, the build cylinder assembly 2 is positioned above the end of the guide rail assembly 1, making it easy for the operator to load materials. After the operator issues a start command, the control assembly 5 activates, and the guide rail assembly 1 transports the build cylinder assembly 2 to the printing position. Next, the positioning cylinder 3 extends, securing the build cylinder assembly 2 at the printing position. Finally, the leveling assembly 4 activates, adjusting the base plate 200 to maintain a level print surface. After completing these preparatory steps, the control assembly 5 sends a ready signal to the 3D printing body 100.

[0095] This embodiment provides a device for preparing a 3D printer for printing. The 3D printer includes a 3D printing body 100 and a base plate 200 disposed at the bottom of the 3D printing body 100. The device for preparing a 3D printer for printing includes a guide rail assembly 1, a forming cylinder assembly 2, multiple positioning cylinders 3, a leveling assembly 4, and a control assembly 5. The guide rail assembly 1 is fixedly disposed directly below the 3D printing body 100 and is parallel to the base plate 200. The forming cylinder assembly 2 is slidably disposed on the guide rail assembly 1 and is used to drive the forming cylinder assembly 2 to shift between the printing position and the upper position. Multiple positioning cylinders 3 are fixedly mounted on one side of the guide rail assembly 1 and are used to secure the forming cylinder assembly 2 to the printing position. The leveling assembly 4 is fixedly disposed below the guide rail assembly 1 and is used to level the base plate to maintain the overall levelness of the printing surface. The guide rail assembly 1, the positioning cylinders 3, and the leveling assembly 4 are all data-connected to the control assembly 5.

[0096] The following technical effects can be achieved: the control component 5 realizes the automated preparation process before printing, avoids the errors caused by human operation, improves the usability and repeatability of the 3D printer, and thus improves the printing quality of the 3D printer; by greatly simplifying the process requiring manual operation, the time from printing preparation to the actual printing is shortened, the dependence on the operator's experience is reduced, the printing efficiency of the 3D printer is improved, and the preparation operation of the 3D printer is made simpler and more reliable, suitable for a wider user group.

[0098] Specifically, the lower surface of the forming cylinder assembly 2 may be provided with a straight rail slider or a slide groove, which cooperates with the guide rail 11 in the guide rail assembly 1 to achieve a sliding connection between the guide rail 11 and the forming cylinder assembly 2. The driving member 12 may be a driving device such as a servo motor, a sliding drive motor, or a stepping motor.

[0099] Specifically, the guide rail assembly 1 comprises two parallel guide rails 11 and a driver 12 for driving the build cylinder assembly 2. The build cylinder assembly 2 slides in conjunction with the guide rails 11 to achieve smooth movement between different positions. The power output of the driver 12 is fixedly connected to the build cylinder assembly 2, driving the build cylinder assembly 2 along the guide rails 11 between the printing position and the upper position. The driver 12 is also wired to the control assembly 5 to receive control signals and execute corresponding actions.

[0110] The transfer cabin airbag 26 is disposed above the transfer cabin 24 and in contact with the transfer cabin 24 , and can be used to adjust the pressure of the transfer cabin 24 by inflating or deflating.

[0111] Furthermore, a pressure sensor may be integrated into the transfer cabin airbag 26 to monitor the pressure of the transfer cabin airbag 26 in real time.

[0112] Further, such as Figure 1As shown, the leveling assembly 4 includes: a leveling frame 41, a forming axis 42, a forming axis servo 43, a moving distance measuring component 44, a chuck base 45, a first leveling servo 46, a second leveling servo 47, a zero point chuck 48 and a chuck solenoid valve.

[0113] The leveling frame 41 is fixedly arranged below the guide rail assembly 1, one end of the forming shaft 42 is passed through the bottom of the leveling frame 41, the forming shaft servo 43 is fixedly installed on the leveling frame 41, and the power output end of the forming shaft servo 43 is connected to the forming shaft 42; the other end of the forming shaft 42 is fixedly connected to the chuck base 45, the first leveling servo 46 and the second leveling servo 47 are both fixedly installed on the chuck base 45, the power output ends of the first leveling servo 46 and the second leveling servo 47 are fixedly connected to the zero point chuck 48, and the chuck solenoid valve is data-connected with the first leveling servo 46 and the second leveling servo 47.

[0114] Specifically, the leveling frame 41 serves as the foundational support structure for the entire leveling assembly 4 and is fixedly mounted beneath the guide rail assembly 1, providing a mounting platform for other components. The leveling frame 41 can be constructed of high-strength, high-rigidity materials, such as cast iron or alloy steel, to withstand the various forces and moments generated during the leveling process. Optionally, the leveling frame 41 can be bolted to a fixed horizontal surface, such as the ground or a tabletop, beneath the guide rail assembly 1.

[0115] A threaded hole or through hole is provided on the bottom plate of the leveling frame 41. One end of the forming shaft 42 is inserted into the threaded hole or through hole at the bottom of the leveling frame 41 and can be limited by the threaded hole. The other end of the forming shaft 42 is fixedly connected to the chuck base 45. The forming shaft servo 43 drives the forming shaft 42 up and down, thereby driving the chuck base 45 and the components thereon to perform preliminary position adjustment. Furthermore, the forming shaft 42 can have high straightness and coaxiality to reduce vibration and error during movement. The forming shaft servo 43 can be a high-precision, high-response speed servo motor and can be equipped with a high-precision encoder to achieve precise position control and speed regulation.

[0116] The moving distance measuring component 44 can be a high-precision distance measuring component such as a grating ruler or a laser displacement sensor, which is used to detect the displacement change of the forming shaft 42 in real time and feed back the measurement signal to the control component 5.

[0117] The chuck base 45 moves synchronously with the forming shaft 42. The first leveling servo 46 and the second leveling servo 47 can be fixedly installed on the chuck base 45 by bolts. The power output end thereof is fixedly connected to the zero-point chuck 48. By controlling the movement of the two leveling servos respectively, the multi-degree-of-freedom leveling action of the zero-point chuck 48 can be realized, thereby achieving the purpose of precise leveling. Furthermore, the first leveling servo 46 and the second leveling servo 47 can both be high-precision, high-resolution servo motors, and equipped with high-precision reducers to improve the leveling accuracy and stability. Specifically, the motor shaft of the leveling servo motor can be fixedly connected to one end of the top screw shaft through the reducer, and the other end of the top screw shaft is connected to the zero-point chuck. When the first leveling servo 46 or the second leveling servo 47 rotates, it can drive the top screw shaft to rotate and lift the zero-point chuck 48, thereby changing the position of the zero-point chuck 48.

[0118] The zero-point chuck 48 is the final execution component of leveling and is in contact with the substrate 200 . By adjusting the position and posture of the zero-point chuck 48 , the substrate 200 can be brought into a horizontal state.

[0119] The chuck solenoid valve is connected to the first and second leveling servos 46, 47, and is used to control the air or hydraulic pressure required to drive the first and second leveling servos 46, 47. By controlling the air or hydraulic pressure of the two leveling servos, the position and posture of the zero-point chuck 48 are adjusted.

[0120] Specifically, the forming axis servo 43, the moving distance measuring device 44, the first leveling servo 46, the second leveling servo 47, and the chuck solenoid valve in the leveling assembly 4 can all be data-connected to the control assembly 5 to achieve automated control of the leveling assembly 4. The control assembly 5 can receive feedback signals from the moving distance measuring device 44 and, based on a preset leveling algorithm, precisely control the movement of the forming axis servo 43, the first leveling servo 46, and the second leveling servo 47, as well as the action of the chuck solenoid valve, to achieve leveling of the substrate 200.

[0121] Next, how the machine preparation device for a 3D printer automatically realizes machine preparation is described in detail.

[0122] Figure 3 A schematic diagram of a process for preparing a 3D printer provided in an embodiment of the present application Figure 1 The method uses the above-mentioned device for preparing a 3D printer. Figure 3 As shown, the method includes:

[0123] S301: In response to a start instruction triggered by a user, start a control component.

[0124] Specifically, after the user turns on the computer, in response to a startup instruction triggered by the user, the control component 5 starts up and automatically activates the full-process automated preparation program.

[0125] S302: Execute a multi-modal safety interlock verification operation to obtain a machine preparation verification result.

[0126] Specifically, after the control component 5 enters the machine preparation control mode, it can first perform a multi-modal safety interlock verification operation, including verifying the locking status of multiple positioning cylinders 3, the pressure size of each airbag, the position of the forming cylinder 21, the zero point position of the first leveling servo 46 and the second leveling servo 47, etc., to obtain the machine preparation verification result.

[0127] S303. When it is detected that the result of the machine preparation verification is successful, the guide rail assembly is controlled at a first reference speed to drive the forming cylinder assembly to move toward the printing location, and when it is detected that the distance between the forming cylinder assembly and the printing location reaches a preset distance, the guide rail assembly is controlled at a second reference speed to drive the forming cylinder assembly to move to the printing location.

[0128] Specifically, the second reference speed is less than the first reference speed. When it is detected that the result of the on-machine preparation verification is a verification failure, an alarm can be issued and the process can be paused to wait for manual intervention. When it is detected that the result of the on-machine preparation verification is a verification success, the control component 5 can control the guide rail component 1 to drive the forming cylinder component 2 to move toward the printing position at a preset first reference speed, so that the forming cylinder 21 can quickly approach the position of the printing position. When it is detected that the distance between the forming cylinder component 2 and the printing position reaches a preset distance, the control component 5 can switch the speed of the guide rail component 1 to a preset second reference speed, so as to control the guide rail component 1 to drive the forming cylinder component 2 to move to the printing position at the second reference speed, thereby achieving high-precision positioning.

[0129] S304: Control the leveling assembly to move upward, and detect the lifting position of the forming axis in real time.

[0130] Specifically, after the forming cylinder 21 moves to the printing position, the control component 5 can control the leveling component 4 to move upward, and detect the lifting position of the forming shaft 42 in real time by moving the distance measuring component 44.

[0131] S305 , when it is detected that the lifting position of the forming shaft reaches a first preset coordinate point, the chuck solenoid valve is triggered to open.

[0132] Specifically, when it is detected that the forming shaft 42 is lifted to the first preset coordinate point, the control component 5 can trigger the chuck solenoid valve opening instruction to provide power support for the subsequent leveling action of the substrate 200 through the chuck solenoid valve.

[0133] S306: When it is detected that the lifting position of the forming axis reaches a second preset coordinate point, the plurality of positioning cylinders are controlled to perform a mechanical locking operation to fix the forming cylinder at the printing position.

[0134] Specifically, when it is detected that the forming shaft 42 is lifted to the second preset coordinate point, the control component 5 can control the multiple positioning cylinders 3 to act synchronously to firmly lock the forming cylinder assembly 2 at the printing position.

[0135] S307 : When it is detected that the lifting position of the forming shaft reaches the third preset coordinate point, a pressure switching operation is performed, and the leveling component is controlled to perform a substrate leveling operation.

[0136] Specifically, when it is detected that the forming shaft 42 is lifted to the third preset coordinate point, the control component 5 can perform a pressure switching operation, adjust the position of the transfer cabin 24 by controlling the pressure state of the cylinder airbag 22 and the transfer cabin airbag 26, and control the leveling component 4 to automatically level the substrate 200.

[0137] S308 , performing a pre-printing environmental pre-check operation, and controlling the energy system to enable after the environmental pre-check passes.

[0138] Specifically, control component 5 can perform pre-printing environmental parameter checks. Environmental parameters can include key indicators such as temperature, humidity, dust concentration, gas concentration, oxygen content in the build chamber, and wind speed to ensure that the printing environment meets process requirements. If the environmental pre-check passes, control component 5 can activate the energy system, such as activating the laser functional safety interlock circuit, and load the preset scanning path and energy density parameters to put it into operation.

[0139] S309: Generate a print ready signal to complete the machine preparation.

[0140] Specifically, after confirming that all preparation actions have been completed and the system status is normal, the control component 5 can generate a print ready signal to notify the user that the print job can be started.

[0141] Figure 4 A schematic diagram of a process for preparing a 3D printer provided in an embodiment of the present application Figure 2 In this embodiment Figure 3 Based on the embodiment, how to perform the multi-modal safety interlock verification operation in step S302 is described in detail. Figure 4 As shown, the method includes:

[0142] S401: Detect the locking status of multiple positioning cylinders and obtain a locking status detection result.

[0143] Specifically, to ensure that all key components and systems of the 3D printer are in the correct state before starting operation, the control component 5 can first perform a multi-modal safety interlock verification operation, including detecting the locking state of the positioning cylinder, the pressure level of the airbag, the position of the building cylinder, and the zero point position of the leveling servo, and based on these test results, determine whether to allow the machine preparation device to enter the next step of operation.

[0144] Specifically, the control component 5 can detect the status of each positioning cylinder 3 through a sensor or a switch to determine whether it has reached a preset locking position, thereby ensuring that the forming cylinder 21 is stably fixed.

[0145] S402: Detect the pressures of the cylinder airbag and the transfer cabin airbag to obtain airbag pressure detection results.

[0146] Specifically, the control component 5 can use a pressure sensor to measure the pressure values ​​of the cylinder airbag 22 and the transfer cabin airbag 26, and compare them with the preset safety range to ensure that the pressure of the cylinder airbag 22 and the transfer cabin airbag 26 meets the preset safety standards, thereby preventing operational failure or safety hazards caused by insufficient pressure or excessive pressure.

[0147] S403: Detect whether the forming cylinder is at the mechanical lower limit position, and obtain the forming cylinder position detection result.

[0148] Specifically, the control component 5 may use a limit switch or other forms of position sensors to check whether the forming cylinder 21 is located at a preset mechanical lower limit position, so as to avoid starting the printing process at a non-printing position.

[0149] S404 , verify whether the first leveling servo and the second leveling servo are at the zero position, and obtain a zero position verification result.

[0150] Specifically, the control component 5 can verify whether the actual positions of the first leveling servo 46 and the second leveling servo 47 are zero positions through an encoder or other position feedback device to ensure that the first leveling servo 46 and the second leveling servo 47 are both at zero positions.

[0151] S405. When the locking state detection result, the airbag pressure detection result, the forming cylinder position detection result and the zero point position verification result are all verified to be passed, the verification passed is obtained as the machine preparation verification result; otherwise, the verification failed is obtained as the machine preparation verification result, and an early warning signal and a fault log are generated.

[0152] Specifically, if the four tests for the locking state, airbag pressure, build cylinder 21 position, and leveling servo zero position all pass verification, the overall machine preparation verification result is considered passed, and the machine preparation device can proceed to the subsequent steps. If any test result fails verification, the overall machine preparation verification result is considered failed. In this case, the control component 5 can generate an early warning signal to notify the operator and record a fault log for subsequent analysis and maintenance.

[0153] Furthermore, in the above step S304, the leveling assembly is controlled to move upward, and the lifting position of the forming shaft is detected in real time, including: controlling the forming shaft servo to start, driving the forming shaft to move upward, moving the chuck base upward, and detecting the lifting position of the forming shaft in real time by moving the distance measuring part.

[0154] Specifically, the control assembly 5 can activate the forming shaft servo 43 to drive the forming shaft 42 to move upward along its axial direction. The upper end of the forming shaft 42 is fixedly connected to the chuck base 45, thereby driving the chuck base 45 to rise synchronously.

[0155] During the lifting process, the control component 5 can use the mobile distance measuring device 44 to collect real-time displacement data on the forming shaft 42. The mobile distance measuring device 44 can then feed back the collected position signal to the control component 5, which is used to determine whether the forming shaft 42 has reached a preset coordinate point. Based on this feedback signal, the control component 5 can then execute subsequent triggering actions, such as opening the chuck solenoid valve, triggering the locking action of the multiple positioning cylinders 3, or initiating leveling of the base plate 200.

[0156] Furthermore, in the above step S307, a pressure switching operation is performed, including: controlling the cylinder airbag to open so that the pressure of the cylinder airbag reaches a first preset pressure value; controlling the transfer cabin airbag to close and performing a steady-state delay operation to reduce the pressure of the transfer cabin airbag to a second preset pressure value to adjust the transfer cabin; collecting the signal of the transfer cabin cylinder in real time, and when it is detected that the signal of the transfer cabin cylinder is a locking signal, controlling the transfer cabin airbag to restart to complete the pressure switching operation.

[0157] Specifically, control assembly 5 first activates cylinder airbag 22, raising its internal pressure to a first preset value to establish a stable support and sealing environment. Subsequently, control assembly 5 deactivates transfer chamber airbag 26 and initiates a steady-state delay sequence, gradually reducing the pressure within the transfer chamber airbag to a second preset value, thereby completing the adjustment of transfer chamber 24. During this process, control assembly 5 continuously collects and monitors feedback signals from transfer chamber cylinder 25. Upon detecting a locking signal, control assembly 5 reactivates transfer chamber airbag 26, restoring its operating pressure, thus completing the entire pressure switching process.

[0158] Furthermore, in the above step S307, the leveling component is controlled to perform a substrate leveling operation, including: controlling the forming axis servo to continue to operate, so that the forming axis drives the chuck base to continue to move upward until the forming axis moves upward to a preset substrate leveling position; obtaining substrate horizontal data, and determining the first leveling servo adjustment data and the second leveling servo adjustment data based on the substrate horizontal data; controlling the first leveling servo to perform a first leveling operation based on the first leveling servo adjustment data, and controlling the second leveling servo to perform a second leveling operation based on the second leveling servo adjustment data to complete the substrate leveling operation.

[0159] Specifically, the control component 5 can continue to drive the forming shaft servo 43 to operate, driving the forming shaft 42 to continue to move upward along its axial direction until the forming shaft 42 reaches the preset substrate leveling position.

[0160] At this point, the control assembly 5 can collect substrate level data from the substrate 200 using a leveling instrument mounted on the substrate 200. This data is then analyzed and processed to determine the adjustment data required for the first leveling servo 46 and the second leveling servo 47 to perform leveling. Furthermore, the control assembly 5 can control the first leveling servo 46 to perform a first leveling operation based on the first leveling servo adjustment data, and control the second leveling servo 47 to perform a second leveling operation based on the second leveling servo adjustment data. The two leveling servos work together to fine-tune the zero-point chuck 48, bringing the substrate 200 to an overall horizontal state, thereby completing the leveling operation for the substrate 200.

[0161] Furthermore, in the above step S308, a pre-printing environmental pre-inspection operation is performed, including: collecting the oxygen content and wind speed in the molding chamber in the printer body; when it is detected that the oxygen content is within the preset oxygen content range and the wind speed is within the preset parameter range, it is determined that the environmental pre-inspection has passed.

[0162] Specifically, the control component 5 can collect key environmental parameters in the molding chamber inside the 3D printing body 100. The key environmental parameters include at least: the oxygen content in the molding chamber and the air flow rate (i.e., wind speed). The control component 5 can compare the collected oxygen content value with the preset oxygen content range threshold, and compare the wind speed value with the preset wind speed parameter range. If it is detected that the oxygen content in the molding chamber is within the preset oxygen content range and the wind speed is within the preset parameter range, it is determined that the current printing environment meets the process requirements, and an environmental pre-inspection pass signal can be generated. Otherwise, it is determined that the environmental pre-inspection fails, and the control component 5 can generate an early warning signal and record a fault log, while preventing the subsequent printing process from continuing.
