Example Embodiment

[0021] Example 1

[0022] like figure 1 and figure 2 As shown, the present embodiment 1 provides a novel intelligent 3D printing system, including: a cloud server, a monitoring terminal connected to the cloud server and a 3D printer; wherein the 3D printer includes: a controller connected to the controller A temperature and humidity sensor and a communication module; the temperature and humidity sensor is suitable for collecting temperature and humidity data in the 3D printer chassis and sending it to the cloud server through the communication module; and the cloud server is suitable for sending the temperature and humidity data to the monitoring terminal.

[0023] The 3D printer also includes: an alarm module connected to the controller; the cloud server stores a temperature threshold and a humidity threshold; when the temperature data in the 3D printer chassis exceeds the temperature threshold or the humidity data exceeds the humidity threshold, the control The controller controls the alarm module to send alarm information; and sends the alarm information to the monitoring terminal through the cloud server.

[0024] Specifically, the controller is, for example but not limited to, a PLC controller; the communication module is an Ethernet interface module, a WiFi module, etc.; the temperature threshold is 80° C.; the humidity threshold is 80%.

[0025] Specifically, the new intelligent 3D printing system of this embodiment detects the temperature and humidity data in the 3D printer chassis through the temperature and humidity sensor, and sends an alarm message when the temperature data exceeds the temperature threshold or when the humidity data exceeds the humidity threshold, so as to monitor the terminal Abnormalities are found at the first time, and countermeasures are taken in time to ensure the printing quality.

[0026] In addition, because each layer of the model printed by the existing 3D printer has a certain height, the model after printing usually appears stepped, causing distortion, and the greater the height of each layer, the more obvious the distortion, thus The precision of the printed model is not high.

[0027] In order to reduce the printing error and make the printed model more accurate, in the first embodiment, the controller 8 is provided with a storage module 81, a switching module 82 and a processing module 83; the 3D printer also includes: a support 1, a storage Component 2, high-precision jet pump 3, guide rail 4, print nozzle 5, drive assembly 6 and workbench 7; wherein the support 1 is located above the workbench 7, and the guide rail 4 is located on the support 1; The driving assembly 6 is controlled by the processing module 83 to drive the printing nozzle 5 to move above the worktable 7 along the guide rail 4; one end of the high-precision jet pump 3 is connected to the storage assembly 2, and the other end is connected to the printing nozzle 5; and the processing module 83 is adapted to control the 3D printer to switch between the normal printing mode and the edge printing mode through the switching module 82 .

[0028] Specifically, the material detection module is suitable for detecting the amount of remaining printing materials in the material storage assembly 2; the storage module 81 is used to store data; the processing module 83 generates the printing path of the 3D printer according to the 3D model, and controls The high-precision jet pump 3 squeezes the printing material in the material storage assembly 2 into the printing nozzle 5, and sprays the printing material to the workbench 7 through the printing nozzle 5 to complete printing.

[0029] The print nozzle 5 is provided with a magnetic shrapnel structure 51 and a shrapnel suction device 52; the shrapnel suction device 52 includes an upper suction point 521 and a lower suction point 522; in the edge printing mode, the processing module 83 according to the current printing point, that is, the coordinates of point j in row i and the coordinate relationship of point j′ corresponding to point j in row i-1, to adjust the pull-in state of the magnetic shrapnel structure 51 .

[0030] Specifically, in the normal printing mode, the elastic sheet suction device 52 does not work, and the magnetic elastic sheet structure 51 is in a free state; The i-1 line corresponds to the j' point coordinate relationship corresponding to the j point, and adjusts the suction state of the magnetic shrapnel structure 51. Specifically, when the j point coordinate is located outside the j' point, the upper suction point 521 moves, and when the j point coordinate When it is located inside point j′, the lower suction point 522 moves, so that the surface of the printed 3D model is inclined and forms a natural arc by the cohesion of the printing material, thereby eliminating the sense of step and making the printed model more accurate.

[0031] The processing module 83 is suitable for judging whether the current printing point is located on the contour line, if so, enter the edge printing mode through the switching module, otherwise adopt the normal printing mode.

[0032] Specifically, during the printing process, the processing module 83 judges in real time whether the current printing point is a contour point, and when the printing point is a contour point, the switching module 82 switches the printing mode to the edge printing mode, otherwise the printing mode is set to for normal printing mode.

[0033] In the edge printing mode, the processing module 83 is adapted to obtain the relative displacement of the current printing point, and its formula is as follows:

[0034]

[0035] Among them: n is the total number of layers printed; i is the current number of layers printed; d i is the printing height; d 0 is the minimum motion length of the 3D printer; x ij 、y ij They are the X-axis coordinates and Y-coordinates of the current printing point j respectively; x (i-1)j 、y (i-1)j are the coordinate point j' of the i-1 layer contour line corresponding to point j respectively; η i is the adjustment coefficient of the i-th layer, η i=f(i), f(t) is a nonlinear function about t; and the drive assembly 6 drives the print head 5 to move in the corresponding direction L ij.

[0036] Specifically, when the current printing point is on the contour line, the processing module 83 first moves the printing nozzle 5 to the current printing point through the drive assembly 6, and then switches the printing module of the 3D printer to the edge printing mode through the switching module 82 , and according to the relative displacement L ij , to control the print head 5 to move to a more precise position; there are many ways to adjust the precision of the drive assembly 6 in the prior art, which will not be discussed in detail here. A larger step is used in the non-edge part of the print, and a larger step is used in the print edge. When using a smaller step size, and through the relative displacement L ij Control adjustment not only makes the printing efficiency high, but also the printed model is closer to the actual product; due to the reasonable calculation of L ij , to realize driving the printing nozzle 5 to be adjusted to the most suitable position with high precision.

[0037] The minimum movement distance D of the printing nozzle 5 in the normal printing mode is the minimum movement distance d in the edge printing mode 0 10 times.

[0038] Specifically, in the normal printing mode, the driving assembly 6 drives the print head 5 to move a minimum distance of D, and in the edge printing mode, the drive assembly 6 drives the print head 5 to move a minimum distance of d 0 , in this embodiment, D=10d 0.
