Context: Recently Japan built a 3D-printed train station in six hours.
What is 3D Printing?
- 3D Printing is a process of creating three-dimensional objects from digital models by adding material layer by layer. It is also known as additive manufacturing.
- It is an additive process, in which layers of a material like plastic, composites or bio-materials are built up to construct objects that range in shape, size, rigidity and colour.
- It allows the creation of complex shapes and structures with high precision.
How 3D Printing is done?
- The basic principle of 3D printing involves building an object layer by layer.
- It starts with a digital model or a computer-aided design (CAD) file, which is sliced into thin cross-sectional layers.
- The 3D printer then reads these slices and deposits or solidifies material one layer at a time, gradually building up the final object.
- Various 3D Printing Technologies: Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Binder Jetting etc.
