Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
An embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon; when the computer program is executed by the processor, a test model corresponding to the model file can be printed by using the 3D printing device, and the test model is used for indicating offset data of a printing head in the 3D printing device. The model file may be a Gcode format file that is printable by a printer. It is understood that the model file may be a file in other format, and the model file may be printed by a 3D printer.
In this embodiment, after the test model corresponding to the model file stored in the readable storage medium provided by the embodiment of the present invention is printed by the 3D printing device, the user can directly read the offset data of the printing head in the 3D printing device by using the offset data of the printing head in the 3D printing device indicated by the test model, which not only reduces the measurement process of the offset data of the printing head in the conventional scheme, but also reduces the process of manually operating the 3D printing device, and particularly when the 3D printing device is produced in batch, the workload of manual operation can be effectively reduced, so that the method is more suitable for batch operation.
The number of the printing heads of the 3D printing device mentioned in this embodiment may be multiple, that is, the number of the printing heads of the 3D printing device is two or more, and the 3D printing device may be an independent multi-printing-head printer or an integrated multi-printing-head printer.
Alternatively, the test model in this embodiment may be printed by a 3D printing apparatus including a first print head and a second print head. That is to say, the 3D printing apparatus for printing the test model may include a first print head and a second print head, where the first print head and the second print head may be two print heads arbitrarily selected from the 3D printing apparatus, and the test model may be obtained by jointly printing with the first print head and the second print head.
The test model printed based on the model file in the present embodiment may include a plurality of model units 10, and each model unit 10 includes a first test unit 11 and a second test unit 12 corresponding to the first test unit 11. A plurality of first test units 11 and a plurality of second test units 12 in the plurality of model units 10 respectively form a first test model 1 and a second test model 2; the first test pattern 1 corresponds to a scale value corresponding to offset data indicative of an offset of the second printhead relative to the first printhead. The first test unit corresponds to the second test unit, and each first test unit corresponds to one second test unit.
Fig. 1 shows an overall plan view schematic diagram of a test model according to an embodiment of the present invention, where model units sequentially arranged in two directions perpendicular to each other in fig. 1 are model units 10 in the embodiment, as can be seen from fig. 1, the test model may include a plurality of model units 10, and the test model shown in fig. 1 may include 13 model units 10 distributed in the X-axis direction and the Y-axis direction. When the first printing head is not deviated relative to the second printing head, the first test unit 11 and the second test unit 12 of the model unit with the X-axis direction and the Y-axis direction crossed are overlapped, and the first test unit 11 and the second test unit 12 of other model units are not overlapped. If the first printing head does not deviate relative to the second printing head, the 3D printer needs the first printing head to print at the point A, and the 3D printer needs the second printing head to print at the point A, both the second printing head and the first printing head can print at the point A, and if the first printing head deviates relative to the second printing head, and the deviation distance is a, the second printing head can print at the point A, and the first printing head prints at the distance a from the point a.
Fig. 2 is an exploded schematic view of the test model shown in fig. 1, and as can be seen from fig. 2, each model unit 10 may include a first test unit 11 and a second test unit 12 corresponding to each other in position, taking the model unit marked with "-0.3" in fig. 2 as an example, the test unit marked with "-0.3" at the top is the first test unit 11 in the model unit, and the test unit marked with "-0.3" at the bottom is the second test unit 12 in the model unit 10. As mentioned above, the test model in the present embodiment may include a plurality of model units 10, and correspondingly, the plurality of model units may include a plurality of first test units 11 and a plurality of second test units 12. The plurality of first test units 11 may form a first test model 1 in a test model, fig. 3 shows a schematic diagram of the first test model in the test model corresponding to fig. 1 and 2, and fig. 4 shows a schematic diagram of a second test model in the test model corresponding to fig. 1 and 2.
Optionally, the first test unit 11 and the second test unit 12 are cubes with the same size; alternatively, the first test unit 11 and the second test unit 12 are both scale marks. In addition to the first test unit 11 and the second test unit 12 in the test model shown in fig. 1-4 being cubic, the first test unit 11 and the second test unit 12 may be respectively configured as the first test model 1 and the second test model 2 in the form of scale marks, and further, an offset value corresponding to the scale marks is used as offset data between the first test model 1 and the second test model 2. Of course, in practical applications, the first test unit 11 and the second test unit 12 may be arranged in other forms, which is not limited in this embodiment of the present invention.
As mentioned above, the test pattern may be printed by a 3D printing apparatus including a first print head and a second print head, alternatively, the first test pattern 1 may be printed by the first print head, and the second test pattern 2 may be printed by the second print head, as can be seen from fig. 1 to 3, the first test pattern 1 may further correspond to a scale value, and the scale value is used for corresponding to offset data indicating the first print head relative to the second print head. In practical application, a first print head in the 3D printing apparatus may be a print head to be adjusted for printing the first test model, a second print head may be a reference print head for printing the second test model, and after the first print head and the second print head print and generate the first test model 1 and the second test model 2 respectively and form the generated test model, the corresponding offset data between the first print head and the second print head may be determined by determining a scale value corresponding to the test model aligned by the first test unit 11 and the second test unit 12. The scale values may be the values set on the first test model 1 as shown in fig. 1 and fig. 2, and the corresponding offset data between the first print head and the second print head can be read quickly and accurately by the scale values in the first test model 1.
It will be appreciated that the first test pattern corresponds to a scale value which may not be displayed and which may need to be determined manually. For example, in the scale, a scale mark, such as 1,2 or 3, is displayed every 10mm from the origin, so as to correspond to 1cm, 2cm or 3 cm. The scale markings 1,2 or 3 etc. may not be present, but the scale lines correspond to a scale value.
Optionally, as shown in fig. 2, the test model in this embodiment may further include a base 3; the first test pattern 1 or the second test pattern 2 is disposed on the base 3. As shown in fig. 2 and 4, the second test pattern 2 may be disposed on the base 3 to fix the position of each second test unit 12 in the second test pattern 2. Of course, in practical applications, both the first test pattern 1 and the second test pattern 2 may be disposed on the base 3, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, the first test pattern 1 and the second test pattern 2 are stacked one above the other or distributed side by side. The test patterns shown in fig. 1 to 2 represent a first test pattern 1 and a second test pattern 2 stacked one on top of the other. Fig. 6 is a schematic top view of a test pattern according to another embodiment of the present invention, fig. 7 and 8 respectively show a first test pattern 1 and a second test pattern 2 constituting the test pattern shown in fig. 6, and as can be seen from fig. 6, the first test pattern 1 and the second test pattern 2 can be distributed side by side on a base 3 to form a test pattern.
With continued reference to fig. 1 to 4, in the present embodiment, the plurality of model units are sequentially distributed at intervals along the origin of the printing coordinate system corresponding to the 3D printing apparatus in the positive direction and the negative direction of the first direction and the second direction perpendicular to each other. Optionally, the X axis, the Y axis, and the Z axis are distributed in a moving direction of the 3D printing device in space, and optionally, the first direction may be an X axis direction of a printing coordinate system of the 3D printing device, and the second direction may be a Y axis direction of the printing coordinate system. In the X-axis and Y-axis directions, there are 13 model units, each model unit is composed of a first test unit 11 and a second test unit 12 corresponding in position, and the second test unit 12 corresponds to a scale value. After the test pattern is printed, the pattern is observed in the X-axis direction and the Y-axis direction respectively, offset values are read, and then the offset values of the printing head are adjusted. It is to be understood that the number of model elements in the first direction and the second direction is not limited in this application.
In the first test model 1 of the test model provided by the embodiment of the invention, first distances between any two adjacent first test units 11 are equal; in the second test model 2, the second distances between any two adjacent second test units 12 are equal; the first pitch and the pitch are unequal. Taking the first test model shown in fig. 3 as an example, the distances between any two first test units 11 in the X-axis direction and the Y-axis direction in the first test model are the first distances, and it is assumed that a; in the second test pattern 2 shown in fig. 4, the distance between any two first test units 11 in the X-axis direction and the Y-axis direction is constant, and is a second distance, which is assumed to be b, where a is not equal to b, and a may be greater than b or smaller than b. Fig. 5 is a partially enlarged schematic view of the test model shown in fig. 1, and as can be seen from fig. 5, the first test unit 11 and the second test unit 12 at the origin point coincide with each other, and since the first distance a is greater than or less than the second distance b, in the X-axis direction, the first test unit 11 and the second test unit 12 in the other model units do not coincide with each other except the model unit at the origin point.
Furthermore, in a printing coordinate system of the 3D printer, a model unit at a crossing position of the first direction and the second direction is an origin test model, a scale value corresponding to a first test model of the origin test model is 0, scale values corresponding to different first test models are different, and the 3D printing apparatus sets the first test unit of the origin test model to coincide with a second test unit of the origin test model.
That is, taking the test model shown in fig. 1 as an example, the model element at the intersection position of the X-axis direction and the Y-axis direction may be defined as an origin test model, where the model element that is located at the origin of the printing coordinate system is referred to as an origin test model. According to the above description, each model unit 10 includes the first test unit 11 and the second test unit 12, therefore, the origin test module also includes the first test unit 11 and the second test unit 12, and the corresponding first test unit of the 3D printing apparatus disposed at the origin test model may coincide with the second test unit of the origin test model, that is, if the first print head and the second print head have no offset, the corresponding first test unit 11 and the corresponding second test unit 12 at the origin test model coincide; if the first print head and the second print head are shifted, the corresponding first test unit 11 and second test unit 12 at the origin test model are not overlapped, and the first test unit 11 and second test unit 12 of the model unit 10 at other positions may be overlapped.
As can be seen from fig. 1 and 3, each model unit 10 in this embodiment has a scale mark, and can display a scale value corresponding to the first test model and used for indicating the offset data of the first print head relative to the second print head; the scale mark corresponding to each model unit 10 is set according to the distribution direction of the model unit in the first direction or the second direction and the distance from the origin. The scale markings facilitate the user in determining the scale value. Referring to fig. 1 and 3, the test pattern has 13 pattern units 10 in each of the X-axis and Y-axis directions, the scale mark at the origin may be 0, the scale marks of the pattern units in the positive X-axis and Y-axis directions may be +0.1, +0.2, +0.3, +0.4, +0.5, and +0.6, respectively, and the scale marks of the pattern units in the negative X-axis and Y-axis directions may be-0.1, -0.2, -0.3, -0.4, -0.5, and-0.6, respectively. The above description only schematically introduces the definition method of the scale mark corresponding to each model unit, and in practical applications, the user-defined setting may also be performed in combination with the size, precision, and the like of the print object, which is not limited in the embodiment of the present invention.
As mentioned in the above embodiments, the 3D printing apparatus includes a first print head and a second print head; the first test pattern 1 is printed by a first print head and the second test pattern 2 is printed by a second print head; the scale mark corresponding to each model unit 10 is set corresponding to each first test unit 11 in the model unit 10. Alternatively, the scale mark is disposed on the first testing unit, or the scale mark is located on one side of the first testing unit 11, such as the scale mark disposed on the base 3.
When the test model is used, taking the test model shown in fig. 1 as an example, when the offset data is read, the determination may be performed according to the overlapping condition of each model unit 10 in the first test model and the second test model. If the left edges of the model cells with scale marks not equal to 0 are aligned (overlapped), the numbers on the model cells are read, for example, if the left edges of the model cells with numbers equal to 0.2 are aligned, the offset value is 0.2. The left edge of the model element with the number-0.2 is aligned, then the offset value is-0.2.
The left edges of all the model units are not aligned (not coincident), at the moment, the first test unit positioned above the model units needs to be observed, two adjacent model units of the first test unit, which are deviated in opposite directions, are found out, and the scale marks corresponding to the two model units are read and the middle value is taken. For example, if the first test cell of the 0.3 model cell is shifted to the left and the first test cell 11 of the 0.2 model cell is shifted to the right, the read data is 0.25. And observing the upper edge and the lower edge of the Y-axis model unit, wherein the reading method of the deviation value is the same as the reading method of the model unit on the X-axis.
Finally, the offset data of the first printing head relative to the second printing head can be input through an operation interface of the printing equipment, and the printing equipment is adjusted to automatically compensate the obtained data. In addition, the read offset data is subtracted from the design size of the printing equipment, so that the offset distance of the actual printing head in the corresponding direction can be obtained, and the obtained actual distance can be input into the model slicing software interval setting or directly input into the 3D printer, so that the sizes of the models printed by the plurality of printing heads are not deviated. In practical application, the first test unit 11 and the second test unit 12 in each test unit in the test model printed by the printing device may not be overlapped, and the relative offset directions of the first test unit 11 and the second test unit 12 in each model unit 10 are the same, at this time, the offset data corresponding to the model unit 10 with the smallest offset data may be selected and input into the 3D printing device, and then the test model is printed once again, and the corresponding offset data is determined again.
Fig. 9a and 9b are schematic diagrams respectively showing a front view and a whole view of a two-color model printed under the condition of offset of the space size of the printing heads of the 3D printing device, and the models printed by the two printing heads cannot be overlapped by observation. Fig. 10a and 10b are a front view schematic diagram and a whole schematic diagram of a two-color model printed by a print head of a 3D printing device after adjustment according to an embodiment of the invention. By comparison, after the offset data between the two printing heads of the 3D printing device is obtained by the scheme provided by the embodiment, the models printed by the two printing heads can be overlapped.
An alternative embodiment of the present invention also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, is operable to print a test model corresponding to a model file using a 3D printing device, the test model indicating offset data of a print head in the 3D printing device. The test model comprises a plurality of model units, and each model unit 10 comprises a first test unit 11 and a second test unit 12 corresponding to the first test unit 11 in position. The first test unit 11 and the second test unit 12 are cubes with the same size; alternatively, the first test unit 11 and the second test unit 12 are both scale marks.
The first test units 11 and the second test units 12 in the model units 10 respectively form a first test model 1 and a second test model 2 which are stacked up and down or distributed side by side. In addition, the test model may further include a base 3, and the first test model 1 or the second test model 2 may be disposed on the base 3 to achieve a fixing function.
The 3D printer can comprise a first printing head and a second printing head, wherein the first printing head is a reference printing head, the second printing head is a printing head to be adjusted, the first test model 1 is printed by the first printing head, and the second test model 2 is printed by the second printing head. Each first test unit 11 in the first test model 1 corresponds to a scale value for corresponding offset data indicating the first print head relative to the second print head.
