The following describes a photocuring 3D printing method and a photocuring 3D printing system according to some embodiments of the present application with reference to fig. 1 to 5.
Example one
Referring to fig. 1, an embodiment of the present application provides a photocuring 3D printing method, including the steps of:
moving the forming platform downwards;
extracting a cavity formed between the release medium and the light-transmitting member to a first negative pressure state, and then exposing to perform photocuring treatment on the printing material;
after exposure is finished, a cavity formed between the release medium and the light-transmitting component is extracted to a second negative pressure state, and the forming platform moves upwards to carry out stripping operation;
and after the stripping operation is finished, if the printing is continued, repeating the steps, and if not, stopping the printing.
According to the method, before exposure, the air pressure in the cavity is adjusted to be in a negative pressure state, so that the release medium is attached to the upper surface of the light-transmitting member, sufficient flatness is provided, and the uniformity of a printing surface is ensured; when peeling off, the air pressure in the cavity is adjusted to be in a negative pressure state, so that the forming platform can move upwards for a short distance to complete the separation of the release medium and the printing piece, and the deformation amount of the release medium is smaller than that of the conventional bulging state, thereby being beneficial to the backflow of printing materials such as resin and further reducing the printing time.
In the above step, the air pressure adjusting device may be used to extract the cavity formed between the release medium and the light-transmitting member to a first negative pressure state, and then the forming platform moves downward and is exposed.
In this embodiment, preferably, in the first negative pressure state, a pressure of a cavity formed between the release medium and the light transmissive member is defined as a 1;
in the second negative pressure state, the pressure of a cavity formed between the release medium and the light-transmitting member is defined as a 2;
wherein a2 is more than or equal to a 1.
When a2 is more than a1, the release medium can be loosened and softened, so that a printed part can be conveniently peeled off from the release medium, the upward moving distance of the forming platform is reduced, the printing efficiency is improved when the printing is saved, the deformation amount of the release medium is smaller, the resin backflow is facilitated, and the printing pressure can be further reduced;
when a2 is a1, the pressure in the chamber does not need to be changed by an air pressure adjusting device or the like, that is, the pressure state in the chamber does not need to be changed, and the molded product can be peeled off without change.
Therefore, in the photocuring 3D printing method provided by the embodiment, the printing time can be greatly shortened, and the printing efficiency can be improved.
Example two
Referring to fig. 2, an embodiment of the present application further provides a photocuring 3D printing system, and based on the photocuring 3D printing method described in any of the above embodiments, the photocuring 3D printing system includes: the device comprises a lifting mechanism 1, a forming platform 2, a material tray 3, an air pressure adjusting device 4 and a light source 5; the forming platform 2 is connected to the lifting mechanism 1, and the lifting mechanism 1 can drive the forming platform 2 to be close to or far away from the material tray 3; specifically, the shaping platform 2, the tray 3, and the light source 5 are arranged from top to bottom along the vertical direction.
The charging tray 3 comprises a release medium 6 and a light-transmitting component 7, a cavity 12 is formed between the release medium 6 and the light-transmitting component 7, and the cavity 12 is communicated with the air pressure adjusting device 4;
the tray 3 is provided with a light-transmitting portion through which the light source 5 can irradiate light to the light-transmitting member 7.
The explanation of "light-transmitting" in the light-transmitting member 7 is that it means that something has a property of at least transmitting light that causes the printing material 10 to undergo polymerization, and specifically, "light-transmitting" may mean that something is at least transmitting ultraviolet light, and alternatively, the light-transmitting member 7 may be light-transmitting glass.
Before the photocuring 3D printing system works, the printing material 10 needs to be placed in a space enclosed between the base 31 and the clamping member 32, and then the photocuring 3D printing system starts to work, and the specific working steps are as follows:
the lifting mechanism 1 drives the forming platform 2 to move downwards; extracting a cavity 12 formed between the release medium 6 and the light-transmitting member 7 to a first negative pressure state by using the air pressure adjusting device 4, and irradiating the release medium 6 by using the light source 5 through the light-transmitting part of the base 31 and the light-transmitting member 7 in sequence for exposure so as to perform photocuring treatment on the printing material 10; after the exposure is completed, the air pressure adjusting device 4 is used to draw the cavity 12 formed between the release medium 6 and the light-transmitting member 7 to a second negative pressure state (note that, at this time, the pressure a2 of the cavity 12 in the second negative pressure state is greater than the pressure a1 of the cavity 12 in the first negative pressure state, and if a2 is equal to a1, the air pressure of the cavity during the peeling is the same as the air pressure of the cavity during the exposure, so that the step can be omitted, and the following peeling operation is directly performed), and the lifting mechanism 1 drives the forming platform 2 to move upwards to drive the printing element 11 to move upwards, so that the printing element is separated from the release medium 6 to perform the peeling operation; and after the stripping operation is finished, if the printing is continued, repeating the steps, and if not, stopping the printing.
In the above step, the air pressure adjusting device 4 may be used to first extract the cavity 12 formed between the release medium 6 and the light-transmitting member 7 to a first negative pressure state, and then the forming platform 2 may be moved downward and then the exposure process may be performed.
As can be seen from the above working steps, before exposure, the air pressure in the cavity 12 is adjusted to a negative pressure state, so that the release medium 6 is attached to the upper surface of the light-transmitting member 7, thereby providing sufficient flatness and ensuring uniformity of the printing surface; during stripping, the air pressure in the cavity 12 is also adjusted to be in a negative pressure state, so that the molded product table can move upwards for a short distance to complete the separation of the release medium 6 and the printing piece 11, thereby reducing the printing time, and in addition, the deformation amount of the release medium 6 is smaller than that in the conventional bulging state, being beneficial to the backflow of the printing material 10 such as resin and further reducing the printing time.
Optionally, the air pressure adjusting device 4 may be a pump body, or the air pressure adjusting device 4 may be a combined structure of a vacuum generator and an adjusting valve, which is not limited to this, and the structure may also be set according to actual needs.

The structure of the light-transmitting portion is not limited to this, and the light-transmitting portion may be a light-transmitting element embedded in the middle of the base 31, or a part or all of the area of the base 31 may be made of a light-transmitting material;
the release medium 6, the light-transmitting member 7 and the top end surface of the base 31 are enclosed to form a cavity 12, and the cavity 12 is communicated with the air pressure adjusting device 4 through a ventilation channel formed in the base 31, specifically, the cavity 12 is communicated with the air pressure adjusting device 4 through a pipeline 8 embedded in the channel.
In the working process, before exposure, the air pressure adjusting device 4 adjusts the air pressure in the cavity 12 to a first negative pressure state in a vacuumizing mode; when the stripping is needed, the air pressure adjusting device 4 leads air into the cavity 12, the air pressure in the cavity 12 is adjusted to be in a second negative pressure state through the air pressure adjusting device 4, and the stripping is carried out, or the step is omitted, and the stripping treatment is directly carried out after the exposure.
