It is strange when we heard about a printer who can print an object like a car? Are you agreeing with this statement? Most probably No! But it is true. In the initial days of printing our ancestors were used a manual or a mechanical printer to print any news or articles. I am not going to cover the whole journey of printing technology because it is not a one-day job. Evolution in electronics and mechanical engineering built a foundation in modern printers. Now we are at the level of technology to print an object via using a 3D printer (Here 3D stands for three-dimensional). Before going into the deep, let’s have a brief introduction to a 3D printer.

What is a 3D printer?

It is a kind of printer that uses a layering technique to create or print a three-dimensional object. The 3D printer uses computer-aided design (CAD) to do its job. This printer uses layering materials like plastic, synthetic resin, bio-materials to produce 3D objects. They work from the ground up and pile on layer after layer until the object looks exactly like it was speculated.

3D printers have high flexibility in what can be printed. They can use plastics to print rigid materials like sunglasses or other small toys. It can also produce flexible objects like mobile phone cases. Some of the 3D printers even can print or create extremely powerful industrial objects by using carbon fiber.

Based on materials that are being used, we can classify the categories of 3D printers:

  1. Polymer 3D printers
  2. Metal 3D printers

Polymer 3D printers:

These printers use plastic, polymers, or synthetic resin as raw material. Polymer 3D printer uses below techniques to produce 3D model:

  1. Stereolithography (SLA)
  2. Selective Laser Sintering (SLS)
  3. Poly-Jet
  4. Digital Light Processing (DLP)
  5. Multi Jet Fusion (MJF)
  6. Fused Deposition Modeling

Metal 3D printers:

Printers of this category use metals like steel, titanium, etc. as raw material. Metal 3D printer uses following processes or techniques to produce 3D model:

  1. Direct Metal Laser Sintering (DMLS)
  2. Electron Beam Melting (EBM)

Units inside this gadget:

Every 3D printer mainly contains the following units to perform its action:

  1. Frame
  2. Printing bed
  3. Extruder
  4. Feeder system
  5. Motion controller
  6. Control unit
  7. Power supply
