Īn STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. Binary files are more common, since they are more compact. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. This file format is supported by many other software packages it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing.

STL has several backronyms such as “Standard Triangle Language” and “Standard Tessellation Language”.

Choosing the right file can not only speed up the machining speed, but also improve the quality of your project.STL is a file format native to the stereolithography CAD software created by 3D Systems. The applications are different, and the selected file formats are different. The user should make a choice between the two formats according to their processing needs. Its characteristic is that the picture will not be distorted after enlargement, it has nothing to do with the resolution, and the file takes up less space. Because this type of image file includes independent separate images, you can freely Restricted regrouping. Vector files are based on geometric characteristics to create graphics, vectors can be a point or a line, vector graphics can only be generated by software, and the file takes up less connotative space. Therefore, a choice or compromise must be made between image quality and calculation speed. However, the higher the resolution, the higher the demands on the computer. If the number of pixels is too small, the resulting image will appear colorful and broken. The higher the resolution, the better the image quality. The resolution of a bitmap image defines the number of squares or 'pixels' in the image. Before the machine starts to work, the beginner must describe the files required for the operation of the machine, and this file is the tool path of the project, that is, and the format is nothing more than bitmaps and vector graphics.īitmaps are color squares that the computer uses to piece together a picture.
