Problems solved by technology

After the molding process is completed, the support structure needs to be removed, which increases the processing process; secondly, the support structure needs to be in contact with the surface of the three-dimensional model to complete the support, and the removal will affect the flatness of the surface of the three-dimensional model
In addition, when the molding process of the three-dimensional model produces a flexible body, this disturbance will affect the molding accuracy

Embodiment 1

[0033] Such as figure 1 with 4As shown, a kind of three-dimensional model molding equipment provided by the present invention is specifically described. The molding equipment includes a control device and a frame 21 of a U-shaped structure, and a beam 8 is arranged between two side plates 11 of the U-shaped structure. The lower part of the beam 8 is provided with a workbench 2 in the middle of the frame 21, and the workbench 2 is embedded with a photocuring liquid container 1 with a cylindrical structure and an upward opening. The elevating rod 20 is connected to the forming platform 16 which moves up and down, and a sealing ring (not shown in the figure) is arranged between the inner wall of the cylindrical structure and the forming platform 16, so that the photocuring liquid will not leak and will not affect the The up and down movement of the forming platform 16, the lifting rod 20 is connected with the driving device 19 arranged on the bottom plate 18, the top of the form...

Embodiment 2

[0035] The present invention also provides a molding method using a three-dimensional model molding equipment provided with atomization and liquid spreading devices, comprising the following steps:

[0036] Step 1) Slicing and layering the three-dimensional model according to the preset thickness through the computer to obtain several laminated shapes with two-dimensional shapes of the three-dimensional model;

[0037] Step 2) Move the molding platform 16 at the bottom of the light-curing liquid container 1 to a projection height position, which is the height position at which the curing light projection device 9 realizes the focus of the curing light. The atomizing nozzle 23 in the device 5 atomizes the light-curing liquid into fine droplets, and the liquid spreading device moves horizontally above the forming platform 16 along the guide rail 12 so that the fine droplets are laid on the forming platform 16 Form the first layer of light curing liquid;

[0038] Step 3) Use the...

Abstract

The invention relates to the technical field of model forming, in particular to stereoscopic model forming equipment and a forming method using the same. The stereoscopic model forming equipment comprises a rack provided with a working table. The working table is provided with a photocuring liquid container with an upward opening. A forming platform connected with a lifting rod is arranged in a barrel-shaped structure. The lifting rod is connected with a driving device. The forming platform is provided with a liquid laying device which moves back and forth on a guide rail. The liquid laying device is connected with a horizontal driving device and provided with an atomization device. The atomization device is provided with a photocuring liquid inlet and comprises an atomization nozzle connected with the photocuring liquid inlet. The atomization nozzle is arranged in a liquid laying shell. A curing light projection device is arranged on the rack and located above the forming platform. The rack is provided with a liquid level position detection device located above the forming platform. The stereoscopic model forming equipment has small disturbance in the photocuring liquid container, reduces dependence on a supporting structure in the forming process, and is suitable for photocuring forming of flexible bodies.

Description

technical field [0001] The invention relates to the technical field of model solidification molding, in particular to a three-dimensional model molding device and a molding method thereof. Background technique [0002] There are many methods for forming a three-dimensional model, among which the method of curing light-curing resin by ultraviolet rays (SLA) can provide higher forming accuracy and better forming surface flatness. Chinese patent CN203665945U discloses a three-dimensional printer based on DLP projection light curing, including a computer system, an automatic control system, a DLP projection system, a forming pool, a feeding system and a lifting system, which can achieve high-precision continuous light curing molding. Chinese patent CN201410795471.6 discloses a laser 3D printer with a scraping function and its photo-curing printing method. It discloses a laser 3D printer with a scraping function, which includes an outer frame unit for constituting a cost-effectiv...
