How Do 3D Printers Work

3D Printers – What It Is, How It Works, and Examples

An easy-peasy guide about How Do 3D Printers Work is provided here which helps you a lot in differentiating between 3D and other printers. 3D printers are used for creating 3D images by making layers above layers. The earlier 3D printer was launched in the 1980s by Charles W. Hull, and now it is in demand.  The working of modern 3-dimensional printers is as follows:

How Does 3d Printers Work

  1. Model creation 
  2. Slicing 
  3. Printing 

Model Creation 

The first step in 3D printing is to create a structure of a model that is to be printed. This model is usually made by using CAD (Computer Aided Design) software, 3D animation, or 3D scan. 


After the model creation, the slicing process starts, which helps make the unbeatable design or print. This printer uses multiple slides and combines them into one place using the slicing software. These slices make the perfect 3D design by mixing multiple colors. 


Now the final process is to make the print of this design. The 3D printers use digital files and software (Autodesk Fusion) to generate the best three-dimensional objects quickly.

Advantages Of 3d Printers 

  The best things to know about these printers are here:

Freedom Of Design 

These printers allow their users to make a desired design. It generates a new Design by making multiple layers, offering customized design. Here, designers can create numerous desiring shapes and designs easily. Moreover, you can also create all the structures, designs, and shapes of different sizes that are difficult and impossible to generate with other printers. 

3D printers offer three and six degrees of freedom to its users. 


3D printers are eco-friendly and don’t harm the environment. Now discuss the reason why they are considered environment-friendly printers, the reason is that they consume little amount of energy, use a material that is not harmful, and reduce carbon emissions. 

Advantages Of 3d Printers 

Disadvantages Of 3d Printers 

Things that make the 3D printers work less demanding are:

Specific size 

These printers don’t allow designers to create large-size printings, hence they offer just limited and small-size designs. Mostly, the customized size of 3D printers depends upon the material and technology used in it.

The commonly used size of these printers is from 200 to 250 mm. Whereas, the desktop and industrial sizes of 3D printers may be different. 

Material Unavailability 

The material used in these printers is genuine, and it’s much more difficult to get the same if once damaged. So always use these printers wisely to avoid any damage and loss. 

Disadvantages Of 3d Printers 

Types Of 3D printering Processes: 

Numerous types of 3D printers work similarly to these printers. Some of them are as follows:

  1. Stereolithography (SLA)
  2. Selective laser sintering (SLS)
  3. Fused deposition modeling (FDM) 
Types Of 3D printering

Stereolithography (SLA)

The world’s first 3D printer is the Stereolithography (SLA) printer, launched in the 1980s. Features of these printers are sharp working, fast speed, accuracy, smooth surface, and high resolution which makes it more unique among other 3D printers. Moreover, these printers are also best for education to engineer-level printing. 

Selective laser sintering (SLS)

One of the most famous 3D printers, Selective laser sintering (SLS) uses laser technology for creating master-level printings. These printers are best for rapid prototyping, low production runs, warping, layer adhesion, powder removal and many of such tasks. 

Fused deposition modeling (FDM) 

One of the inexpensive 3D printers is fused deposition modeling (FDM) which offers high-quality printing at an affordable price. These printers were invented in late 1989 and now these are widely used for printing toys and other industrial objects. 

Applications of 3D Printing Technology:

These printers are jumping on the bandwagon nowadays due to their printing quality and fast speed. There are many uses for these printers in education, industries, offices, and other work areas. So let’s move toward the uses of 3d printers:

  • Industries 
  • Engineering 
  • Medical field 


These printers are used in manufacturing, medical, fashion, and other large industries for making large equipment. Moreover, in the defense and aerospace industries, these prints prove to be the supreme ones in generating quality prints easily. These printers also allow users to generate unique tools for business purposes. 


Three-dimensional printing helps a lot in engineering by offering users free hand designs and colors. With these printers, engineers can find the best prototypes and solutions to their problems quickly. Mostly mechanical, industrial, and electrical engineers use these printers to fulfill their needs. 

Medical Field 

The best thing for doctors and dentists is that these printers also perform best in the medical fields like other industries. Doctors can use these printers for creating artificial tissue, organs, and teeth that are very helpful for them. Likewise, it also helps in surgery and implant cases wisely. 

What is 3d Printers Printings:

These printers are perfect for any color printing. Three-dimensional printers print three-dimensional objects by making layers by layers, as it has seen by its name. The colors used by these printers in the printing process are given: 

  • White and black 
  • Other colors 
  • Multiple colors 
  • Custom colors 

Do 3d Printers Print Color ?

Of course, these printers print colors as well as white and black printings. Multiple printers perform multiple operations. Now see what three-dimensional printers print:

FDM 3D printers 

  1. These printers are used for printing single color when used along with colored filament 
  2. These are used for printing two colors when used along a dual extruder 
  3. Likewise, these are used for multicolor printing when used along gradients. 

How Do Resin 3d Printers Work?

These printers design the outline of any project and mostly work the same as other 3D printers. When you resin the three-dimensional printings, it long lasts only for 6 to 12 months. After that time these prints expire and using these printings may ruin the printing quality. 

3d Printer Examples 

12 known real-life examples of these printers are here:

  1. Food 
  2. Clothing 
  3. Body parts 
  4. Automotive parts and development 
  5. Buildings health science 
  6. Military 
  7. Musical instruments 
  8. Manufacturing
  9. Military 
  10. Drawings 
  11. Artwork 
  12. Planters  

FAQS – Frequently Asked Questions


Now you know about how do 3D Printers work – What It Is, How It Works, and we see Examples. We can say that 3D printers are the best printers for large-size printing. But it may also depend on printer size and type because some 3D printers are used for small printings whereas some are for large printings. All over, these printers are perfect for every field.
