Abstract

The invention discloses a 3D printing device based on a two-dimensional image, and the 3D printing device comprises a two-dimensional graphic information input interface, a two-dimensional graphic information storage module, a two-dimensional graphic information processing module, a three-dimensional model display interface, and a three-dimensional model printing module. The invention also discloses a three-dimensional modeling method based on a two-dimensional graph, and the method comprises the steps: firstly extracting views of six surfaces of a to-be-printed object; secondly respectively extracting and storing the two-dimensional graphic information of the views of the six surfaces; thirdly carrying out the registration of the two-dimensional graphic information, and generating a three-dimensional model; finally generating an STL file for 3D printing according to the three-dimensional model. According to the invention, the whole modeling process is completed automatically, and the device and method are convenient for operation, are high in production rate, and have certain precision. The device and method exert low requirements for hardware, can be used for platforms and terminals, and is low in resource consumption.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a 3D printing device based on a two-dimensional image and a three-dimensional modeling method thereof. Background technique [0002] At present, 3D printer technology and its related industries have achieved rapid development, and its commercial operation has gradually matured. At present, there are three main modeling methods for 3D printers on the market: the first one, which is also the most commonly used modeling method, is to use professional graphic design software, sampling and interactive methods for geometric modeling; the second one is to use 3D digitization The scanner performs geometric modeling; the third is to use some basic geometric models in existing graphics libraries to create object shapes. [0003] The traditional modeling method, because the modeling process is done manually, is time-consuming, labor-intensive, heavy workload, complex operation, professional...

AI Technical Summary

Problems solved by technology

[0003] The traditional modeling method, because the modeling process is completed manually, is time-consuming, labor-intensive, heavy workload, complex operation, requires professional training, it is difficult to get started, and commercial software is too expensive

When converting the built geometric model into STL format, there will be many incompatibilities and modifications that need to be made, and the requirements for computer hardware are relatively high. Generally, professional 3D modeling software cannot be installed on mobile terminals such as mobile phones or tablets.
