How Does 3D Printing Work?

How to create a 3D printing part and what is required? Let's explore the process of 3D printing.

1. First of all, a three-dimensional digital file of the object you want to print is needed. There are three different ways to get a 3D digital model: design, scan, and download. CAD is a common software to design a 3D model, popular CAD software including AutoCad, SolidWorks, Tinkercad and more. 3D scanning is a technology to analyze a real-world object and create a digital replica. You can also download one from a 3D library.

2. Once you get a 3D model, you need to convert it into a proper file format. The most common 3D printing file format is STL, which is a usable file extension. Alternatives to STL are .OBJ and .3MF, these formats do not contain color information, if you need colored 3D printing objects, .X3D, .WRL, .DAE, and .PLY can be used. Ensure the file whether is printable.

3. Slicing is the process of dividing the three-dimensional model into hundreds or thousands of layers, then generate the G-code to tell the machine how to execute the operation step by step. G-code is the most widely used CNC programming language applicable for CNC machines and 3D printers.

4. Use 3D printers to complete the printing process according to automated G-code instructions.

5. Remove the finished 3D printed parts from the printer. For some machines, it is easy, while the removal of 3D prints for some industrial 3D printers requires professional skills and specialized equipment.

6. In some cases, additional steps or post-processing is need to finish the production. For example, various surface finishing methods are used to improve the aesthetics and mechanical properties of 3D printed components.
