How does 3D printing works?

3D printing

The specialized term for 3D printing is Additive Manufacturing. 3D printing is a procedure whereby a 3D configuration is transformed into a genuine article. To start with, programming is utilized to cut the 3D structure into layers, and after that, the plan is printed layer by layer on a 3D printer. Since each article is developed remarkably, 3D printing is extraordinary if you need to make one of a kind and modified things or little arrangement of items. Interestingly, different procedures, for example, infusion embellishment are greatly improved at making thousands or a large number of duplicates of something economically.

How 3D printing work

3D printing works in 4 steps, 3D CAD file, slicing, 3D printing, and final-physical object. All the four steps of 3D printing are mentioned below:

3D CAD file

To make a 3D object, it is important to make a 3D design of the object you want to print. Without accomplishing this step, 3D printing is not possible. The most common way to create the digital model is to use computer-aided design named CAD. There are multiple software available to make the 3D designs; however if you do not want to use the software, you can use the 3D scanner to get the image design. Another way to get the 3D design in no time to download a premade design from various sites.

Once you are done with the CAD design, now it’s time to change the design into the format that is acceptable for 3D printing. The most commonly used 3D printing file format is STL, also called stereo lithography.


This is the next step for 3D printing here the formatted file is converted into the instruction that is understandable by the 3D printer. In 3D printing, slicing is referred to as the division of the 3D formatted file into multiple layers to tell the printing machine what to do. Once the file is sliced, the sliced file is given a new format called G-code. G-code is the numerical coding programming language that is understandable by machines such as 3D printers.

3D printing

The 3D printing machine is made with multiple moveable parts, so it is important to give proper maintenance to the machine. Proper maintenance will always lead to excellent 3D prints, and that’s what we all want from our machines. Once the G-coded file is transferred to the machine, the rest of the work will be performed automatically. You need not worry about the work as long as no software issue occurs in the machine while the printing process. The entire printing process is quite smooth and quick as all the work or printing is done by the printer on its own based on the G code of the object.


Once the 3D object is formed, your work is almost done. You will notice that when you take the 3D object out of machine, it will be a bit rough. That’s not an issue at all; you can vanish that roughness in the final step. After the object is made, it is painted, lacquered or sanded as per manufacturer desire to give it a fine finish.
