Description
Technical Field
The invention relates to the field of printing, in particular to a three-dimensional printer, a printing method of the three-dimensional printer and a printing device of the three-dimensional printer.
Background
The 3D printer, also known as a three-dimensional printer, is a machine that utilizes a rapid prototyping technique, and constructs a three-dimensional entity by using a modeling material based on a digital model file and by means of an accumulation modeling. Before printing, modeling is carried out by using computer modeling software, and the built three-dimensional model is partitioned into section layers, namely, slices are layered, so that the 3D printer is controlled to print layer by layer.
The currently common layering methods can be divided into three types. The method comprises the steps of carrying out hierarchical self-adaption according to information such as normal vectors of patches in the STL model, and carrying out self-adaption layering directly on a CAD solid model and carrying out self-adaption layering by using an accurate three-dimensional model, so that the solid model can be accurately imaged. For example, an article, "adaptive layering method based on a Z-direction characteristic curve of a 3D CAD model surface", published in < mechanical science and technology > > No. 29, No. 5 of 2010, such as Wangzweichen, proposes a rapid adaptive layering algorithm based on multiple interest features of a model surface, wherein the algorithm utilizes the Z-direction characteristic curve to extract the interest features of the CAD model surface, and rapidly determines the adaptive layer thickness at a layering point through a direct mapping relation from the geometric features of the characteristic curve to the layer thickness, and the whole layer thickness calculation process has no redundant calculation.
The existing common layering error calculation standard comprises a pinnacle height criterion which is generally used for calculating the layer thickness according to the topological information of a model and the allowed maximum pinnacle height, but fails when the normal vector of the model is close to the vertical direction, and an area difference ratio criterion which is used for judging whether the layering height is proper or not according to the area difference of the profiles of two adjacent layers, reducing the layering height when the area difference is large, or increasing the layering height, wherein the method has great advantages in processing simple models. The user can choose to use one of the three methods for three-dimensional solid imaging for the shape and size of the different models.
However, because the color mixing of different colors is required in the printing head, the printing head is more complicated compared with other monochrome printing heads, so the manufacturing cost of the color three-dimensional printer is high, and the printing cost is also higher. Meanwhile, the printing head cannot mix more colors, so that the colors of the three-dimensional solid model are complex, the color reduction degree is low, the image resolution is low, and inconvenience is brought to users.

Printing method of three-dimensional printer the first embodiment:
referring to fig. 3, fig. 3 is a flow chart of a printing method of the three-dimensional printer. When the three-dimensional solid model 19 is subjected to color solid imaging, step S1 is first executed to start the three-dimensional printer 1. Then, step S2 is executed, a model file with data of the three-dimensional solid model 19 is input into the memory of the three-dimensional printer 1, and then step S3 is executed, the processor of the three-dimensional printer performs slicing and layering according to the three-dimensional solid model 19 shown in fig. 4, the three-dimensional solid model 19 is a cone and is provided with a through hole along the axis Z of the three-dimensional solid model 19, and after the processor performs slicing and layering on the three-dimensional solid model 19 along the axis Z, data of N layered models with different diameters are obtained through processing, wherein one layered model is the layered model 192 shown in fig. 5. Subsequently, step S4 is executed, the processor divides each layer model into a color region and a monochrome region, which is exemplified by the layer model 192 in fig. 5, the processor sets the outermost edge portion of the layer model 192 as the color region 193, the processor sets the innermost edge portion of the layer model 192 as the color region 195, the color regions 193 and 195 are both distributed in a ring, and the processor sets the region between the color region 193 and the color region 195 as the monochrome region 194.
After the division of the color area and the monochrome area is completed, step S5 is subsequently performed, and the print head 2 and the inkjet head 3 perform color solid image formation according to the color area and the monochrome area, specifically, referring to fig. 6, fig. 6 is a flowchart of the image forming step of the print head 2 and the inkjet head 3. When step S5 is executed, step S51 is executed first, the print head 2 ejects the filament material in the molten state according to the monochrome area 194 to perform solid imaging, step S52 is executed after the print head 2 finishes the solid imaging of the monochrome area 194, the print head 2 ejects the filament material in the molten state according to the color area 193 and the color area 195 to perform solid imaging, and then step S53 is executed, and the inkjet head 3 ejects ink on the layered model 192 according to the color area 193 and the color area 195. As the filament material is generally made of ABS plastic, the filament material in a molten state can be dissolved with the sprayed ink, thereby realizing color imaging of the layered model. Of course, if the material of the filament material is polyvinyl chloride (PVA), the ink may be water-based ink, and the water-based ink is compatible with the PVA, so that color imaging of the layered model can be realized.
In addition, the inkjet head 3 in the above embodiment works after the printing head 2 completes the solid imaging of the color area 193 and the color area 195, and the inkjet head 3 can also work simultaneously with the printing head 2, that is, the inkjet head 3 follows the motion track of the printing head 2, and the inkjet head 3 performs the color imaging on the filament material just extruded and formed by the printing head 2, which is beneficial to more uniform color blending and simultaneously improves the imaging speed.
After the printhead 2 and the inkjet head 3 complete the color solid imaging of the layered model of one layer, the processor proceeds to step S6 to add one to the imaging times M, and then proceeds to step S7 to determine whether the imaging times M is equal to the number N of layered models, if M is less than N, it indicates that the solid model 19 does not complete the imaging, and returns to step S5 to continue the color solid imaging of the layered model of the next layer. Until the solid model 19 completes all color solid imaging, that is, the imaging times M are equal to the number N of layered models, then step S8 is executed, after the solid model 19 is cooled and solidified, the solid model is taken out from the three-dimensional printer, and then color imaging of the three-dimensional solid model is completed.
As can be seen from the above, since the edge portion of each layered model is color-imaged, after each colored layered model is stacked, color three-dimensional solid imaging is achieved. Of course, the above-mentioned layer model 192 is only illustrated as a layer model in the entity model 19, and in practice, the layer model may be set as a color area for all its areas or a monochrome area for all its areas, and the ratio of the color area to the monochrome area may be adjusted according to the actual needs of the user.

Of course, the ink-jet head 3 can also work simultaneously with the printing head 2, that is, the ink-jet head 3 follows the motion track of the printing head 2, and the ink-jet head 3 performs color imaging on the filament material just extruded by the printing head 2. The sequence adjustment of the steps in the imaging step S5 is also beneficial to the user to adjust the sequence of actual imaging according to different solid models while achieving color imaging, and is beneficial to improving the quality of the three-dimensional model.
Printing method of three-dimensional printer third embodiment:
on the basis of the first embodiment of the printing method of the three-dimensional printer, the imaging step S5 of the print head 2 and the inkjet head 3 can also adopt the sequence of steps as shown in fig. 8, specifically, when step S5 is executed, step S57 is executed first, the print head 2 performs solid imaging on the layered model 192 according to the layered solid model data of a single layer, and after the layered model 192 completes imaging, step S58 is executed, the inkjet head 3 ejects ink on the layered model 192 according to the color region 193 and the color region 195.
