Description

Technical Field

[0001] The present invention relates to 3D printing, and particularly to a multi-functional 3D printer. Background Art

[0002] With the development of China's economy and the improvement of people's living standards, the production of personalized products in China has increased day by day, driving the booming development of 3D printing technology. With the booming development of 3D printing in China, how to improve the existing 3D printing technology to enhance its universality for different needs has become an urgent problem to be solved.

[0003] There are three printing technology principles for existing 3D printers: SLA, FDM, and SLS. Among them, SLA is stereolithography printing, which uses the characteristics of photosensitive resin and cures it by irradiating with ultraviolet laser; FDM is fused deposition modeling printing, which extrudes consumables through a heating nozzle and realizes printing by cooling and stacking; SLS is selective laser sintering, which sinters printing material powder into a shape using a laser. Among them, the two printing principles of SLA and FDM are the two most commonly used printing principles.

[0004] Currently, FDM printer devices have poor printing accuracy and slow forming speed, but they have a wide range of printing consumables, strong material selectivity, and low prices; while SLA printer devices have great limitations in material selection and can only choose photosensitive resin. The equipment is expensive, but it has high printing fineness and high appearance quality. For different user needs, different machines need to be selected, which leads to the production side having to prepare different machines, resulting in high costs.

[0005] To solve the above problems, CN201710442315.5 proposed a new type of 3D printer and its usage method, which installs a laser on the base of the FDM print head to achieve the function of SLA. However, in the actual use process, the FDM print head will inevitably affect the use of the SLA print head, thus unable to truly achieve the SLA function.

[0006] Therefore, there is an urgent need in the market for a multi-functional 3D printer that can fully implement two different 3D printing modes of SLA and FDM. Summary of the Invention

[0007] To solve the above technical problems, a multi-functional 3D printer is disclosed in the present invention. The technical solution of the present invention is implemented as follows:

The X-axis motion component and the Y-axis motion component are fixed on the XY-plane frame. The Z-axis motion component is parallel to the support columns and fixed on the base and the top frame. It is characterized in that: it further includes a printing material tank and an upper sealing plate. The printing material tank includes a tank wall and a release film. The release film is arranged at the bottom of the printing material tank. The printing material tank is arranged on the XY-plane frame. The upper sealing plate is fixed on the top frame.

[0009] Preferably, the upper sealing plate includes a fixed bracket and a stereolithography apparatus (SLA) printing mesh plate. The SLA printing mesh plate is detachably fixed on the fixed bracket.

[0010] Preferably, the printer head is detachably installed on the motion component. The printer head is one of a fused deposition modeling (FDM) printer head or an SLA printer head.

[0024] In a specific embodiment, such as Figure 1 and Figure 2As shown in the figure, a multi-functional 3D printer includes a printer frame, a motion component, a printer head 1, and a control center.

It is characterized in that: it further includes a printing material tank 9 and an upper sealing plate 10. The printing material tank 9 is arranged on the XY-plane frame 4. The upper sealing plate 10 is fixed to the top frame 5.

[0025] In this specific embodiment, the printer frame is used to provide support for the whole. The base 3 is used to provide support for the whole device and to hold the semi-finished product during FDM printing. The support columns 2 are perpendicular to the base 3, one end of which is arranged on the base 3 and the other end is arranged on the top frame 5. The XY-plane frame 4 is slidably sleeved on the support columns 2 and can move up and down along the direction of the support columns 2. During this process, the Z-axis motion component 8 provides power and controls its movement. The number of the Z-axis motion components 8 is not less than 2, so as to ensure the motion stability of the XY-plane frame 4. The top frame 5 plays a fixing role on the one hand and provides an installation platform for the upper sealing plate 10 on the other hand. The XY-plane frame 4 is used to fix the X-axis motion component 6 and the Y-axis motion component 7.
