What is CNC 3D model?

Nowadays, more and more CNC 3D models are used in various CNC machines, even in small workshops or at various DIY enthusiasts, various CNC machines and 3D printers can be found. So it is important for you to have a command of 3D models if you don’t want to fall behind compared to other people.

In 3D computer graphics, 3D modeling (or three-dimensional modeling) is the process of developing a mathematical representation of any surface of an object (either inanimate or living) in three dimensions via specialized software. The product is called a 3D model, someone who work with 3D models may be referred to as a 3D artist. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices. 

In CNC machines, the formats of 3D models are as following:

3D models:

·STEP, IGES, Para solid X_T or 3DM (Rhinoceros 3D software) extensions (Solid or surface models – NURBS) – suitable for all 3D CAD/CAM programs like NX, Catia, Solid Edge, Solid Works, Rhino3D, Master CAM, Edge CAM and similar 3D CAD/CAM programs.

·OBJ extension (polygon mesh) –suitable for all 3D programs like: Blender, 3D Studio, Maya and similar.

·STL format - suitable for 3D printing

3D Models are suitable for import and editing in majority of CAD/CAM programs so you can use them as you need.

The best CAD file format for CNC 3D models to share is the STEP file. STEP stands for Standard for the Exchange of Product model data. The lack of file interchangeability has been a huge headache in the field of manufacturing and product design for a long time. The STEP-file was introduced to make it more uniform.

Having a watertight 3D model is very important. A single, unified 3D model is a lot easier to work with and eliminates a lot of room for error when it comes to creating a CNC machining program or preparing the model for 3D printing. When it comes to 3D printing, a non-watertight model will generate error messages when trying to generate the G-Code. Plugging the holes, so to speak, can be quite time-consuming and delay the manufacturing process.
