3D technologies were not included, but simply burst into the life of modern society. 3D printers and CNC routers have found their place in this world and are in great demand. It is not difficult to work with them, many already have such printers or CNC milling machine at home and use them, because the main thing for work is to have STL model. Today there is no problem with this, as there are many sites on the Internet that offer the necessary models, both for free and for a certain amount. STL is the file format that is used to store these models.
To have a general idea of the 3D modeling process, it is worth getting to know some information more closely.
What is a 3D model?
3D model is a real or fictional object, presented in the form of a three-dimensional digital image. Such models are created using special software created for these purposes. Despite the fact that the functionality of the programs has a significant difference, still a large number of applications include clear functions that are aimed at performing the necessary tasks.
3D modeling refers to the entire process in which a three-dimensional digital image of the required object is created. The requirements for this process are always different, they completely depend on the goals set. For example, there is a significant difference in the modeling order associated with the development of computer games and with the creation of 3D models for 3D printing. Modeling, using new technologies, is especially in demand among designers and in industrial production. It is much more effective than the drawings familiar to all, as it makes it possible to evaluate the characteristics of objects at the initial stage of work.
3D models for CNC machines
3D models for CNC milling machines are presented in the form of a mathematical representation of the object. Three main types of models are distinguished:
- Superficial when there is an idea of the contour and type.
- Wireframes when an object is only displayed externally.
- Mesh, they are called solid-state, are used when it is necessary to develop new products.
