What is 3D printing?

Melting metal in Additive Manufacturing.

How does it work?

Part 1:

Creating a 3D model of a train using 3D modeling software.

Part 2:

An example of a home 3D printer using FDM technology.
The object (grey) and the support material (white).
3D printed objects printed with Stereolithography technology using wax.
Different examples of using Binder Jetting to create colored prints.

Part 3:

Application of 3d printing in different industries

Future uses and development


Key Takeaways:

  • 3D printing is part of a process known as Additive Manufacturing, which basically just refers to manufacturing something by adding one part at a time.
  • The process includes creating a model using 3D modelling software/scanning a real life object, printing said model, and polishing the final result.
  • 3D design and printing is a very powerful developing technology full of potential that is applicable in almost any field.
