We are introduced to new technologies and innovations that tend to shape our everyday life. 3D Printing is one of the fast-emerging, revolutionary technologies, and it’s also known as additive manufacturing. 3D printing is essentially a different way of producing parts rather than traditional subtractive (CNC machining) or formative (Injection molding) manufacturing technologies.
The 3D printer is provided a digital model of the object which it is required to shape and turn into a physical three-dimensional object by adding material a layer at a time. This is where the alternative term Additive Manufacturing emerged from.

A 3D design usually takes approximately about 4 to 18 hours to complete depending on the size of the part. However, 3D-printed parts are rarely ready-to-use out of the machine. They often require some post-processing to achieve the desired level of surface finish. These steps take additional time and usually require manual effort
The ISO/ASTM 52900 standard categorized all different types of 3D printing under one of these seven groups:Material Extrusion (FDM):
- Material Extrusion (FDM): Material is selectively dispensed through a nozzle or orifice
- Vat Polymerization (SLA & DLP): Liquid photopolymer in a vat is selectively cured by UV light
- Powder Bed Fusion (SLS, DMLS & SLM): A high-energy source selectively fuses powder particles
- Material Jetting (MJ): Droplets of material are selectively deposited and cured
- Binder Jetting (BJ): Liquid bonding agent selectively binds regions of a powder bed
- Direct Energy Deposition (LENS, LBMD): A high-energy source fuses material as it is deposited
- Sheet Lamination (LOM, UAM): Sheets of material are bonded and formed layer-by-layer
A technology that inspires
Nowadays, 3D Printing is widely used all over the world. It dramatically used for the mass customization, production of any types of open-source designs in the field of agriculture, healthcare, automotive industry, locomotive industry, and aviation industries
