Method for obtaining invisaligner master mold through 3D printing and invisaligner master mold

Abstract

The invention discloses a method for obtaining an invisaligner master mold through 3D printing. The method comprises the following steps of modeling a plurality of master mold bodies through modelingsoftware and generating bottom rafts so as to form a plurality of invisaligner master molds; introducing the plurality of invisaligner master molds into 3D printing software, wherein the plurality ofinvisaligner master molds are arranged in an xy-plane and stacked in the Z-axis direction, and a support structure is generated between an upper bottom raft and a lower bottom raft; performing data slicing to form slicing files; importing the slicing files into a printer and printing; and removing the support structure to obtain the invisaligner master molds. The invention further discloses the invisaligner master mold manufactured by using the method. According to the method, by adopting a layout mode of stacking the plurality of invisaligner master molds in the Z-axis direction, the invisaligner master molds are printed; and the Z-axis space of the printer is fully utilized, the arrangement number of the invisaligner master molds in the printing space is multiplied, and the number of themaster molds printed at one time is increased, so that the desktop printer can produce the invisaligner master molds on a large scale, the cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of denture correction, in particular to a method for 3D printing an invisible aligner master mold, and also relates to an aligner master mold. Background technique [0002] Invisible orthodontic technology inherits the traditional orthodontic concept and is a perfect combination of modern stomatology, computer-aided three-dimensional diagnosis, personalized design and digital molding technology. Compared with traditional orthodontic appliances, the invisible orthodontic technology does not require brackets and steel wires, and uses a series of invisible orthodontic appliances, which are made of safe elastic transparent polymer materials, making the orthodontic process almost It is completed without being noticed by others, and does not affect daily life and social interaction. At the same time, without the cumbersomeness of bonding brackets and adjusting arch wires, clinical operations are greatly simplifie...

AI Technical Summary

Problems solved by technology

The entire orthodontic process needs to produce batches of orthodontic appliances, so it is necessary to make a large number of master molds through 3D printers. This process usually needs to be made with large-format industrial 3D printers, but this kind of machine is expensive and difficult to apply to small factories and Clinic

At present, desktop printers with cheap cost, high precision and fast speed are popular in the market, but the printing area is relatively small, and a large number of aligner master molds need to be printed multiple times, which is troublesome to operate and low in efficiency.
