Network storage and calling method and storage system of 3D printing model file

Abstract

The invention provides a network storage and calling method of a 3D printing model file. The method includes the following steps that: 1, an uploading user terminal uploads a model file to a server; 2, a compression module of the server compresses the received model file, and a key seed and the compressed model file are stored respectively; 3, the server responds to a request and calls the compressed model file and the key seed, and then mixes the key seed to obtain an unreadable character string and writes the unreadable character string into page codes as parameters, and returns the page codes to a calling user terminal; and 4, the calling user terminal reads and calls an actual key in the page codes, and decompress the model file. The invention also discloses a network-based 3D printing model file storage system. With the network storage and calling method and storage system of the 3D printing model file of the invention adopted, the security of data and bandwidth performance in transmission can be ensured simultaneously, and efficiency can be improved, and cost can be reduced.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for network storage and calling of 3D printing model files and a network-based 3D printing model file storage system. Background technique [0002] The model file in 3D printing refers to the model document file required in 3D printing, and the 3D model included in it can be created in any 3D modeling software. Common 3D printing model files include more than a dozen types such as STL, OBJ, WRL, and 3DS. [0003] In the model file, the necessary data and mathematical information that constitute a model are described in the document, and some model files include texture files, which are placed outside the model file and called by file references when used. Different from ordinary documents, model files in 3D printing are relatively bloated, often reaching tens of megabytes or even hundreds of megabytes, occupying a large amount of disk space and causing a waste of disk ...
