Adjacent triangles must have two vertices in common.Generally, if your part is outside of these parameters, you'll need to resize it. 5MB for a simple file to 10MB for a large complicated one. stl file is a complete listing of the xyz coordinates of the vertices and normals,the vectors perpendicular to a surface that determine the orientation for the triangles, that describe the 3D object.Ī good. stl or STereoLithography files describe the surface geometry of a 3D object and are used to build physical 3D Cad Models.stl files are created using a mesh made of triangles that represents the physical part of your object. However, if your budget permits you may wish to consider commercial options (read: expensive) such as Rhino 3-D and SolidWorks. The content/theme of your class or programįree and/or open source options that are available:.Your choice of software tool(s) for use with your students will depend on a variety of factors:
There is no shortage of free or commercially available software at your disposal. The GCode tells the 3D printer how to print the object. The software that slices a model is called Makerware, which translates the 3D information into an x3g file or GCode, the common name for the widely used computer numerical control (CNC) programming language). Once you have a STL file, the 3D model needs to be sliced into layers in order to be printed. Using a digital design, it prints objects by melting layers of plastic, one on top of the other, to form three-dimensional objects. The Desktop 3D printers are inexpensive machines that can be either put together or purchased preassembled and allow anyone to participate in personal fabrication and rapid prototyping.
