3D Printing is also known as desktop fabrication. It is a process in which a real object model is created from a 3D design. In year 1986, 3D printing came made its way into the world and gained popularity somewhere around in 1990.
3D Printing is mostly used in medial and architectural industry. In medical industry, with the help of 3D printing, surgeons can create exact replica of human parts which needs to be operated upon. Similarly, architects create a mockup of the building they are about build. The impact of 3D Print models on the architectural industry is undoubtedly the most transforming things to have happened.
For creating an object by 3D printing, first, we need a digitalized 3D model. These models can be created either by downloading them from the internet or by drawing it on a computer with the help of CAD software. The 3D models are then saved in STL format and sent to the printer.
By using 3D Print models we can make take our client on a virtual tour of their product. They can get even minute details of their product. By comparing their proposed design with the 3D model they can understand what changes should be made in designs. In 3D modeling, it is quite easy to see the impact of even a minor change on the whole design. It becomes easy for an engineer to complete the project at low costs.
There are a few different 3D Printing technologies. The main difference between them is the way layers are built in each one of them. Some of the widely used techniques are:-
- Selective Laser Sintering (SLS)
- Fused Deposition Modeling (FDM)
- and Stereolithography (SLA)
Many different materials are used for the 3D printing, like polyamide, glass filled polyamide, silver, steel, and titanium etc.
In near future 3D printing is going to be very important for so many industries, like automobile, medical industry, education industry, business & industrial equipment, architecture, and consumer-product industries.
