Scope of application
3D printing design process is: first modeling through computer modeling software, and then build the three-dimensional model "partition" into a layer-by-layer cross-section, that is, to guide the printer layer-by-layer printing. The standard file format for the collaboration between the design software and the printer is the STL file format. An STL file uses triangles to approximate the surface of an object. The smaller the triangular face is, the higher the surface resolution is. PLY is a scanner that generates three-dimensional files by scanning, and the resulting VRML or WRL file is often used as an input file for full-color printing.
