What is 3D Printing? How does 3d print work?

Since 1983, 3D printing has undergone a change and breakthrough in the printing process since then. 3D printing is an interesting technology that changes the face of modern production. 

Whether you are familiar with 3D printing technology or want to fix a few flaws, Most of us have heard of 3D printing. But we actually don’t know what is 3D Printing and how does a 3D printer print a 3D model?

3D printing products have become more popular in recent years as 3D printing technology have become more popular.


But in this article, we present the history and reality of 3D printing – what is 3D printing, who invented 3D printer, its processes, materials used in 3D printing, how a 3d printer works and applications of this new technology.


let’s start!

What is 3D printing? How does a 3d print works?


What is 3D Printing?


3D printing has become very popular because it makes production available to many people. 3d printing utilize the computer added design (CAD) to create a three dimensional object.


The creation of a 3D printing object is carried out by means of additive processes, thus It is called as additive manufacturing. The additional process is created by laying successive thin layers of many sequential materials before the object is created. 3D printing causes low material consumption.


3D printing allows you to create complex shapes using fewer materials than traditional production methods.


You can choose to create it from the original or download it from the 3D library.

How Does 3D Printing Work?

The 3D printing process involves stacking layers of melted plastic to create objects. This is the process of 3D printing work and how a 3d printer works.

To print in 3D, you need a digital file that allows the 3D printer to know where to print the material.

The most common file format for this is G-code files.

This file contains “coordinates” that control the movement of the printer horizontally and vertically, also called the X, Y and Z axes.


History of the 3D printing


The earliest discussion of the production of 3D objects through additional layers can be traced back to the 1970s.


In 1981, the first patent for 3D printing was granted to the Japanese Hideo Kodama in 1981. he used ultraviolet light for additive manufacturing.


In 1984, a group of French inventors received the first patent for the stereolithography method, led by Alain Le Mechot. It is still most popular method.

 3D Printers

3D printers are printers that are able to print a 3D material as it is. 3D printers print 3D models by using certain 3D software and 3D printing materials.

Chuck Hull was the person who invented the 3D printer first time. The technology used in this printer was stereolithography.

3D Software

There is a lot of software. From production class to open source.

3D printing technologies

3D printing technology is divided into three categories, 3D printing processes by this way:


Selective laser sintering SLS 3D printing Sintering

SLS 3D printing Sintering (SLS) uses a high-power laser to join plastic, metal, ceramic or glass parts. At the end of the work the remaining material is processed.


Fused filament fabrication (FFF) FFF 3D printing Melting

FFF 3D printing is an auxiliary manufacturing process in which a thermoplastic material is pushed from a heated nozzle to lay layers. FFF technology is usually a cheaper solution than other 3D printing processes.


Stereolithography SLA 3D printing

There, the ultraviolet laser is emitted into a photopolymer that is sensitive to ultraviolet light and monitors the object being formed on its surface. The polymer solidifies where it is exposed to radiation, and the radiation “prints” the object layer by layer according to the instructions.


Sintering is a technique that heats materials before reaching the melting temperature to produce high-resolution objects.

How long does 3D printing take?

Print time depends on several factors, including the size of the part and the settings used for printing. 3D printing can last from a few minutes to several hours or days.
