Technological advancements are a must in all the sections of human life worldwide. Innovation and revolution are constant, which leads to new developments. Technology that we use daily like bulbs, lights, computers, mobile phones, cars and aeroplanes. Everything was merely an idea which was developed with every passing decade.
3D printing is one of the innovative developments by Chuck Hull made in 1984. He invented stereolithography, which created 3D models based on the given data input.
How does a 3D Printer Work?
3D printing follows a coded process to create 3-dimensional models through digitalization. It is done by using CAD (Computer-Aided Design), which helps in designing a physical appearance by adding layers of material. 3D printing gives you two steps for innovation manipulation during digital format and while providing new shapes using additional materials.
Commonly used 3D Printing Technology:
- Stereolithography: one of the fastest prototyping systems. It is mostly used for industries where there is a requirement for accurate and precise outputs. Using a CAD file, it can process the data within an hour or two. It is highly recommended only because of its efficiency for fine detailing and exact final results.
- Digital Light Processing: it is one of the oldest 3D printing machines. It was invented in 1987 by Mr Larry Hornbeck. It has a similar process like SLA. However, it produces high-resolution models. The major difference between these two is the source of light it uses. SLA follows ultraviolet lights, and DLA uses traditional light. It is comparatively cheaper.
- Fused Deposition Model: in the late 1980’s Scott Crump developed the FDM printing process. It uses thermal plastic as a production material. It is highly recommended for concept models and prototypes. It uses accurate data and creates exceptional models.
- Selective Laser Sintering: It was invented in the mid-1980s by Dr Carl Deckard; it was the first 3D printer to be patented. SLS uses CO2 laser techniques for fusing materials together for the final product. It is recommended for the production of customized products.
- Selective Laser melting: it was a project launch of Fraunhofer Insitute ILT German in the year 1995. It uses high-powered lasers. It is highly used in the aerospace industry and medical orthopaedics.
- Electronic Beam Melting: Arcman AB launched EBM in the year 1997. EBM and SLM follow the same procedure throughout expect the power source. EBM uses electronic beams, whereas SLM uses high-resolution beams. It is recommended for complex geometric figures.
- Laminated Object Manufacturing: it was launched by a company named Helisys in California. It is one of the affordable methods of 3D printing; however, despite being one of the fastest operating mechanisms, it’s not popular.
- Binder Jetting: the Massachusetts Institute of Technology invented it; it uses four materials for the production process. Ceramic, plastics, metal, and sand it does not harm nature. It is recommended for the automotive, medical, and aerospace industries.

Which 3D Printers are High in Demand?
To find the best 3D printer in the market is a tough task but we have some options that are most sought after by the majority of the population.
Creality Ender 3 is one of the best options available under $200. It is an extraordinary printer that has a volume of 220 x 220 x 250mm, a BuildTak-like heated build plate, power recovery mode and a tight filament pathway that makes it easier to deal with.
Prusa i3 MK3 is an open-source fused deposition modelling 3D printer and it is the successor to the award-winning Original Prusa i3 MK2/S. Even though this is a costly 3D printer its results are phenomenal for beginners as well as for experts in the game.
According to a market research forecast, the global 3D printing market is valued in millions, growing rapidly from 2018 to 2024. There is an increase in the spending of the market on product development and R&D activities. The major drive behind the 3D printing market’s growth is the rising regulation by national and local government and the manufacturing sector as they support development.
