Clearly, 3D printing or additive manufacturing is a process that makes 3D solid objects from a digital file. The 3D printed object is created using additive processes. In this process, we create an object by laying down successive layers of material.

Obviously, it plays a crucial role in many applications. Furthermore, the most important being manufacturing, medicine, architecture, custom art and design.

Indeed, we call it as “additive manufacturing.” Although we use this term more frequently within the manufacturing industry to describe 3D printing’s role in the industrial process.

Undoubtedly, this is useful to architects for creating mockups and mechanics for creating tools. 3D printing is an innovation which fuels more innovation. Thus, it is inexpensive prosthetics, creating spare parts, rapid prototyping, creating personalized items and manufacturing with minimum waste.

Particularly, every 3D printer builds parts based on the main principle: Generally, we turn a digital model into a physical 3D object by adding material a layer at a time.

The 3D metal printer receives instructions from the computer which instructs the Laser what shape to trace out across the metal powder. The Laser then pulses and heats up the powder which subsequently creates a solid form of the object.

Leading the packs are the giants in aviation, such as Boeing and General Electric. Boeing fully embraces this technology. Interestingly, 3D printing has made more than 20,000 parts across ten different commercial and military planes.

Actually, there are nine basic types: Fused Deposition Modeling (FDM), Stereolithography (SLA), Digital Light Processing (DLP), Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Electron Beam Melting (EMB), Laminated Object
