The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a platform for a 3D printer based on SLA technology, such as... Figure 1-3 As shown, the platform of the SLA-based 3D printer includes: a platform body 2 disposed on the 3D printer body 1, the platform body 2 being used to support and place the printed object; the platform body 2 including a rigid platform 3 and a flexible platform 4, the flexible platform 4 being disposed on the rigid platform 3; and a connecting frame 5 mounted on the platform body 2, the connecting frame 5 being used to install and place the platform body 2.

[0018] In this embodiment, during overall use, the connecting frame 5 is connected to the lifting mechanism on the 3D printer body 1 based on SLA technology. The lifting mechanism on the 3D printer body 1 drives the connecting frame 5 and the carrying platform 2 to move within the material tank storing photosensitive resin, thereby facilitating the printing of items. The printed items are carried by the carrying platform 2, which consists of a rigid platform 3 and a flexible platform 4 set on the rigid platform 3. The rigid platform 3 is made of stainless steel and can provide good support for the flexible platform 4. The flexible platform 4 is made of silicone. After the item is printed, it is carried on the flexible platform 4. The flexible platform 4 can be bent easily. When retrieving the material, the operator only needs to bend the flexible platform 4 to easily retrieve the printed item, avoiding the trouble of using a spatula to retrieve the material and reducing the damage to the carrying platform caused by using a spatula. The entire carrying platform 2 can carry and place the printed item, and the retrieval is convenient and simple, providing convenience for the operator's material retrieval work.

[0019] In a further preferred embodiment of this utility model, the soft platform 4 is provided with a plurality of first through holes 8, and the hard platform 3 is provided with a plurality of second through holes 9. The plurality of first through holes 8 correspond to the plurality of second through holes 9 respectively, and the first through holes 8 and the second through holes 9 are used to drain the photosensitive resin used for printing the items.

[0020] In this embodiment, after the item is printed, the connecting frame 5 and the carrying platform 2 are moved out of the photosensitive resin solution by the lifting mechanism on the 3D printer body 1. At this time, the photosensitive resin is conveniently discharged through multiple first through holes 8 and multiple second through holes 9, so as to avoid the photosensitive resin from accumulating on the carrying platform 2.

[0021] In a further preferred embodiment of the present invention, an installation frame 10 is fixedly installed on the soft platform 4, and a lifting plate 11 is fixedly installed on the installation frame 10. The lifting plate 11 is used to lift the installation frame 10 and the soft platform 4.

[0022] In this embodiment, the mounting frame 10 can maintain the overall shape of the soft platform 4, while facilitating the docking of the soft platform 4 and the hard platform 3. The lifting plate 11 can easily lift the mounting frame 10 and the soft platform 4 from the hard platform 3.

[0023] In a further preferred embodiment of the present invention, a support plate 12 is fixedly installed on the connecting frame 5, and the support plate 12 is used to support and place the loading platform 2.

[0024] In this embodiment, the connecting frame 5 is used to install and place the loading platform 2. On this basis, a support plate 12 is fixedly installed on the connecting frame 5. The function of the support plate 12 is to support and place the loading platform 2. In actual use, the support plate 12 can provide stable and reliable support for the loading platform 2, ensuring that the loading platform 2 remains stable during the printing process.

[0025] In a further preferred embodiment of the present invention, both the support plate 12 and the rigid platform 3 are provided with mounting grooves 13, and a second magnet 15 is fixedly installed in each mounting groove 13. A first magnet 14 is fixedly installed at the bottom of the rigid platform 3 and the bottom of the mounting frame 10, and the first magnet 14 and the second magnet 15 are compatible and adsorbed.

[0026] In this embodiment, in actual use, when it is necessary to connect and fix the soft platform 4 to the hard platform 3, the first magnet 14 at the bottom of the mounting frame 10 and the second magnet 15 in the mounting groove 13 on the hard platform 3 attract each other, thereby fixing the soft platform 4 to the hard platform 3. At the same time, when it is necessary to fix the hard platform 3 to the support plate 12, the first magnet 14 at the bottom of the hard platform 3 and the second magnet 15 in the mounting groove 13 on the support plate 12 attract each other, thereby fixing the hard platform 3 to the support plate 12. The fixing is convenient and simple. At the same time, when it is necessary to disassemble, it can be easily operated by overcoming the magnetic attraction force, which not only ensures the stability of the connection, but also takes into account the convenience of use.

[0027] In a further preferred embodiment of the present invention, a positioning rod 16 is fixedly installed at the bottom of the soft platform 4, and a positioning hole 17 is provided on the hard platform 3, wherein the positioning hole 17 and the positioning rod 16 are adapted to be connected.

[0028] In this embodiment, when the soft platform 4 is installed on the hard platform 3 in actual use, the positioning rod 16 will be accurately inserted into the positioning hole 17. This positioning structure can quickly and accurately determine the installation position of the soft platform 4 on the hard platform 3, ensuring the accuracy and stability of the installation of the soft platform 4, preventing the soft platform 4 from shifting relative to the hard platform 3, and improving the stability of the use of the loading platform 2.

[0029] In a further preferred embodiment of this utility model, both the upper and lower surfaces of the soft platform 4 are frosted.

[0030] In this embodiment, in actual use, this frosted setting increases the friction between the bottom of the soft platform 4 and the hard platform 3, improves the stability of the connection between the soft platform 4 and the hard platform 3, and also increases the friction between the soft platform 4 and the printed object, improving the stability of the printed object.

[0031] In summary, compared with related technologies, this platform can carry and place printed items, and the material retrieval is convenient and simple, providing convenience for staff to retrieve materials.

[0032] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
