Description

Technical Field

[0001] This utility model relates to the field of 3D printer film technology, and more specifically to a micro-nano bump film for 3D printers. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a rapid prototyping technology that constructs three-dimensional solids by depositing materials layer by layer. The core of LCD photopolymer 3D printers lies in using an LCD panel to display the model outline and combining it with ultraviolet light to cure the resin, thus achieving layer-by-layer model building.

[0003] In the resin tank of an LCD photopolymer 3D printer, the cured 3D model of the photosensitive resin comes into direct contact with the LCD screen below the tank. The newly formed 3D model adheres to the LCD screen, and when removing it, the strong adhesion can cause the model to break and damage the LCD screen. Therefore, a release film is usually fixed to the bottom of the resin tank to isolate the 3D model from the LCD screen, allowing the model to be removed intact. However, when the release film is applied to the LCD screen, the bottom surface of the release film sticks to the screen, causing air bubbles to be squeezed out and creating a vacuum environment. External air pressure then presses the release film firmly onto the LCD screen, making it difficult to peel off.

[0004] Therefore, in LCD photopolymerization 3D printers, providing a film with a simple structure and reasonable design that can be attached to the surface of the LCD screen to isolate the release film from the LCD screen and make the release film easy to peel off from the LCD screen is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a micro-nano bump film for 3D printers, which solves the technical problem that the release film used to isolate the three-dimensional model from the LCD screen is not easy to peel off from the LCD screen in LCD photopolymerization 3D printers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A micro-nano bump film for 3D printers can be bonded to an LCD screen or a high-transparency glass with a glossy finish, and a release film can be bonded to the top. The film includes a thin film substrate, the bottom surface of which can be bonded to the LCD screen. The top surface is processed with multiple densely arranged bumps, each bump having multiple microstructures arranged on it. High-definition display is achieved through micro-nano optical technology. The multiple bumps form air channels for ventilation of the release film. The thin film substrate has multiple vent holes extending along its thickness through the multiple bumps, and these vent holes are densely arranged to allow gas to flow between the LCD screen and the release film in the resin tank.

[0008] Through the above technical solution, this utility model discloses a micro-nano bump film for 3D printers. It utilizes optical micro-nano technology to form a layer of bumps on the top of a thin film substrate. Multiple ventilation holes penetrating the bumps are also formed on the thin film substrate. External air entering through these ventilation holes disrupts the vacuum adhesion between the release film and the LCD screen, facilitating the release film's peeling from the upper surface of the thin film substrate. This micro-nano bump film for 3D printers has a simple structure and reasonable design. It improves the release force of the resin tank release film from the LCD screen or high-gloss, high-transparency glass, preventing light spot diffusion. While improving the release function of the release film, it does not affect the clarity of the pattern morphology. It offers fast printing speed and high precision. Furthermore, the bumps can mitigate the impact of the formed 3D model on the LCD screen, extending the LCD screen's lifespan.

[0009] Preferably, a silicone layer that can be bonded to the LCD screen is integrally fixed on the bottom surface of the thin film substrate, and each of the vent holes penetrates the silicone layer.

[0010] The beneficial effect of adopting the above technical solution is that it makes the film substrate adhere more firmly to the LCD screen.

[0011] Preferably, the film substrate is made of polycarbonate material.

[0012] The beneficial effects of adopting the above technical solution are that the film substrate made of polycarbonate is lightweight, soft, has high resistance to high temperature and chemical corrosion, and has high light transmittance with almost no color difference when light passes through it.

[0013] Preferably, the cross-section of the protrusion is polygonal. Attached Figure Description

[0022] See appendix Figure 1 To be continued Figure 3 According to an embodiment of the present invention, a micro-nano bump film for 3D printers can be adhered to an LCD screen 100 or a high-transparency glass with a glossy surface, and a release film can be adhered to the top. The film includes a film substrate 1, the bottom surface of which can be adhered to the LCD screen 100, and the top surface processed with a plurality of densely arranged bumps 11. Each bump 11 has a plurality of microstructures arranged on it, and high-definition display is achieved through micro-nano optical technology. The plurality of bumps 11 form an air channel for ventilation and permeability of the release film. The film substrate 1 has a plurality of ventilation holes 12 that penetrate the plurality of bumps 11 along its thickness direction. The ventilation holes 12 are densely arranged to allow gas to flow between the LCD screen 100 and the release film in the resin tank.

[0023] Specifically, the thickness of the thin film substrate 1 is 0.13 mm.

[0024] Specifically, the film substrate 1 is made of polycarbonate material.

[0025] Films made of polycarbonate materials have a light transmittance of over 90%, are lightweight, soft, and have strong resistance to high temperatures and chemical corrosion.

[0026] Specifically, as viewed from the top view, the cross-sectional shape of each protrusion 11 is polygonal.

[0028] This invention relates to a micro-nano bump film for 3D printers. While the film substrate is bonded to the LCD screen and release film, a layer of bumps is formed on the top of the film substrate using optical micro-nano technology. The bumps support the release film and reduce the impact of the 3D model on the release film on the LCD screen. The film substrate also has multiple ventilation holes that penetrate the bumps. External gas enters between the release film and the LCD screen through the ventilation holes, which will disrupt the vacuum adhesion between the two, making it easier to peel the release film off the LCD screen.
