3D printing is an additive manufacturing process that creates 3D objects by laying down materials layer by layer based on a digital model. It allows for the creation of complex shapes that would be difficult or impossible to make with traditional manufacturing methods. The technology was first developed in the 1980s and has since been used for rapid prototyping, production of consumer goods, medical devices, and more. 3D printers use materials like plastics, metals, ceramics, and composites to build up a digital design into a physical object through various methods like stereolithography, fused deposition modeling, and selective laser sintering. 3D printing offers advantages like reduced material waste, lower costs, and the ability to produce customized designs.

- 2. What is 3D Printing? 3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. Also known as Additive Manufacturing or Rapid Prototyping. It is an additive process where materials are laid down as layer by layer in different shapes of thickness ranging from 0.0254mm to 1mm to make 3D objects. This technology uses a 3D Printing machine connected to a computer containing digital image/data of the object (to be printed) for the printing purpose.
- 3. History 1984-The technology for printing physical 3D objects from digital data(Stereo lithography) was first developed by Charles Hull. 1986 - Charles Hull founded 3D Systems and developed the first commercial 3D Printing machine, it was called as Stereolithography Apparatus. 1988 - Scott Crump invented Fused Deposition Modeling (FDM). 1993 - Massachusetts Institute of Technology (MIT) patented "3 Dimensional Printing techniques".

- 6. Types of Printing Stereolithography: It is an additive manufacturing process using liquid UV-curable photopolymer “resin” and a UV laser to build parts a layer at a time. Fused deposition modeling (FDM): It is an additive manufacturing which uses hot semi-liquid extrude directly to print objects. Laminated object manufacturing(LOM) : In this, layers of adhesive- coated paper, plastic or metal laminates are successively glued together and cut to shape with a knife or laser cutter. Selective laser sintering (SLS): an additive manufacturing technique that uses a high power laser (eg:-, CO2 laser) to fuse small particles of plastic, metal , ceramic or glass powders into a mass that has a desired 3-dimensional shape.
