The embodiment provides a three-dimensional printing method based on a DLP printer, and aims to solve the problems that a copied object needs to be modeled to obtain a 3D model file before a DLP printer is adopted to perform three-dimensional printing operation in the prior art, and the 3D model file is processed by relying on slicing software.
The modeling and slicing processing aim at obtaining the slice single-layer outline information of the copied object, and then the DLP printer can project the surface light layer with a specific outline to the surface of the liquid photosensitive resin layer by layer based on the outline information of each slice single layer, and then the liquid photosensitive resin layer is cured and molded layer by layer, and finally the printed object is obtained. Therefore, if the slice single-layer contour information of the copied object can be obtained by adopting other methods instead of a method of combining modeling and slicing, the dependence on a 3D model file and slicing software in a three-dimensional printing operation of a DLP printer can be avoided.
Therefore, referring to fig. 1, the present embodiment provides a three-dimensional printing method, which includes the following steps:
s1, acquiring the information of the outer peripheral surface of the copied object which is scanned layer by layer along the height direction;
s2, obtaining the outline information of each single layer of the copied object along the height direction according to the information of the outer peripheral surface;
and S3, sending the obtained outline information of each single layer to a printer, and enabling the printer to print the single layers according to the outline information of the single layers to obtain printed products.
By means of the method, the outline information of each single layer of the copied object is obtained in a mode of scanning the peripheral surface of the copied object layer by layer, and then the DLP printer can project surface light with corresponding outlines to the surface of the liquid photosensitive resin based on the outline information of the single layers, so that the liquid photosensitive resin is cured and molded layer by layer, and finally the printed object is obtained. That is, the method is adopted to perform the printing operation, 3D modeling and slicing processing of the 3D model are not needed to be performed on the copied object, and on the contrary, because the data information acquired by scanning the copied object once in the method is only single-layer information of the copied object, the computer computing pressure is greatly reduced.
In an alternative embodiment, step S3 includes: and after each single-layer contour information is obtained, sending the contour information of the current single layer to a printer for printing the current single layer by the printer according to the contour information of the current single layer. Specifically, in the operation process, the steps of scanning each single layer, calculating and acquiring the profile information of each single layer and printing the single layer by the DLP printer can be processed in parallel, namely, after each single layer of profile information is obtained, the DLP printer can print the single layer without waiting for the profile information of all the single layers to be printed layer by layer, and therefore the printing efficiency is greatly improved.
In this embodiment, step S1 may specifically include the following steps:
s11, controlling the copied object to rotate around the vertical axis;
s12, obtaining circumferential distance information between the outer peripheral surfaces of the single layers opposite to the distance measuring elements measured layer by layer;
and S13, obtaining the single-layer contour information according to the circumferential distance information fitting.
Specifically, in order to measure the circumferential distance information of the outer peripheral surface of each single layer of the copied object, a distance measuring element for measuring the distance between the distance measuring element and the measured object (i.e., the copied object) may be fixedly disposed at the side of the copied object, and when the copied object rotates around a specific vertical axis (e.g., a vertical central axis thereof) for one circumference, the distance measuring element can continuously measure and obtain a set of circumferential distance information of the single layer at a height position where the distance measuring element is directly opposite to the copied object, that is, the circumferential distance information in the foregoing, and the computer fits the circumferential distance information corresponding to the single layer to obtain the profile information of the single layer.
In step S1, the copied object scanned layer by layer along the height direction may be scanned layer by layer from bottom to top, or may be scanned layer by layer from top to bottom, which is not limited in this embodiment.
Taking scanning the copied object layer by layer from bottom to top as an example, in the printing operation, the first measured monolayer is the one at the bottom end of the copied object, and after the measurement of the one at the bottom end is completed, the copied object can be lowered or the distance measuring element can be lifted to a specific height (i.e. the thickness of the one at the bottom end) and then the distance measuring element of the second monolayer is aligned, so that the measurement of the second monolayer can be performed, and of course, the two can be lifted to a part of the specific height respectively, which is not limited herein. When the topmost single layer of the copied object is measured and the printing is finished, the printing operation of the copied object is finished.
In an alternative embodiment, step S1 can also be performed by:
s11', moving around the copied object layer by using the distance measuring element to measure circumferential distance information between the outer peripheral surfaces of the single layers facing the distance measuring element;
and S12', obtaining the profile information of the single layer according to the fitting of the circumferential distance information.
In this embodiment, the distance measuring device moves around the copy object fixedly arranged for one circle, and the set of the circumferential distance information of the single layer at the height position directly facing the copy object can be measured and obtained, and then the computer fits the circumferential distance information corresponding to the single layer to obtain the profile information of the single layer.
Similarly, in this embodiment, in order to move around the copied object layer by layer, the distance measuring device and the copied object may perform ascending or descending actions independently, or they may cooperate to complete the adjustment of the height of a single layer.
The thickness of the single layer, that is, the height difference between the distance measuring device and the copied object after being adjusted by lifting each time, is actually the thickness of the single layer copied and printed by the DLP printer each time. And it can be understood that the smaller the thickness of each individual layer and the uniform thickness between individual layers all contribute to improving the surface accuracy of the replica, making the surface of the replica more beautiful and smooth. Of course, the smaller the thickness of each individual layer, the more individual layers the object is divided into, and the longer the cycle time for a single object to be copied, the implementer can make trade-offs based on process requirements.
In this embodiment, the heights of the individual layers are preferably equal, that is, the height difference between the distance measuring element and the copied object after being adjusted by lifting each time is equal, so that the thicknesses of the individual layers printed by the DLP printer each time are equal, the control logic is simplified, the surface precision of the copied object is ensured, and the surface of the copied object is more beautiful and smooth.
In order to perform the printing production by the method, the embodiment further provides a three-dimensional printing apparatus, referring to fig. 2, the three-dimensional printing apparatus includes a measuring mechanism 10 and a fitting mechanism 20, wherein the measuring mechanism 10 is configured to acquire information of an outer peripheral surface of the copied object scanned layer by layer in a height direction. The fitting mechanism is configured to obtain profile information of each single layer of the copied object in the height direction according to the information of the outer peripheral surface, and send the obtained profile information of each single layer to the printer, so that the printer prints the single layer according to the profile information of the single layer to obtain a printed object.
In this embodiment, the measuring mechanism 10 includes a stage 11 and a distance measuring element 12, the stage 11 is used for carrying and rotating the copied object around the vertical axis; the distance measuring element 12 is used to measure circumferential distance information between the outer peripheral surfaces of the single layers facing thereto.
Specifically, the stage 11 includes a rotary table 111 and a table 112 for placing the copied object, and a rotating shaft of the rotary table 111 is vertically disposed and connected to the table 112 so as to drive the table 112 to rotate, and further, the copied object placed on the table 112 can rotate around a vertical axis. The distance measuring device 12 may be a distance measuring device using Time of Flight (TOF) technology such as a two-dimensional laser sensor or a depth camera, and as described above in the three-dimensional printing method, the object to be copied is rotated, and the object to be copied is aligned with the distance measuring device 12 layer by layer from the bottom end to the top end, and the distance measuring device 12 is adjusted to measure and obtain the circumferential distance information of the outer peripheral surface of each single layer of the object to be copied, and then the fitting mechanism 20 fits the circumferential distance information obtained by the distance measuring device 12 to form the profile information of each single layer and transmits the profile information to the DLP printer 40, and the DLP printer 40 can print each single layer. In this embodiment, the fitting mechanism 20 is a computer.
In order to make the copied object face the distance measuring element 12 layer by layer, at least one of the stage 11 and the distance measuring element 12 can be vertically lifted. For example, the carrier 11 may further include a lifting unit 113 (e.g., a lead screw lifting module, etc.), and the lifting unit 113 is disposed between the turntable 111 and the table 112, or disposed at a fixed end of the turntable 111, so as to lift or lower the table, and thus, the object to be copied is lifted or lowered. For another example, the distance measuring device 12 is fixedly connected to a lifting end of a lifting unit 113, and the relative position between the object to be copied and the distance measuring device is adjusted by lifting the distance measuring device 12. For another example, the carrier 11 and the distance measuring device 12 may be configured with a lifting unit 113 to complete the position adjustment. In short, at least one of the stage 11 and the distance measuring element 12 may be provided to be vertically liftable.
In an alternative embodiment, the carrier 11 and the distance measuring element 12 may be arranged in another way, that is, the carrier 11 is fixedly arranged, the distance measuring element 12 is arranged to be capable of moving around the copied object, and circumferential distance information between the surrounding track and the outer peripheral surface of each single layer of the copied object may also be measured, so that the fitting mechanism 20 may obtain the profile information of each single layer based on the circumferential distance information.
