3D modelling is the process of creating a three-dimensional digital visual representation of an actual object using specialised computer software, or the process of developing a mathematical representation of any surface of an object in three dimensions. It was developed for the first time in the 1960s by the creator of Sketchpad, Ivan Sutherland.
In today’s world which is fast growing technologically, 3D models are used in a wide variety of fields. We have the medical industry which uses it to detailed models of organs, the architectural industry, the movie industry, the science sector, the engineering community which uses them as designs of new devices, structures and a host of other uses.
2D which possess the two dimensions (x, y), the additional dimension, the z-axe that is inherent to the 3D acquisitions, gives room for more details there by giving a clear difference between the 2D and 3D.
3D modelling comes with a hand full of advantages to the technological world. Designers uses software such as Solid works, Auto CAD to design and build a graphical and virtual model of their products. This, improves efficiency and save time as any error can be corrected during designing and it’s an economical method that provides manufacturers with the great flexibility to get desired results.
Alongside 3D modelling is 3D printing which refers to a process in which a computer program is used to build a solidified 3D object, mostly prototypes. It involves additive manufacturing, a process in which the design object is built by laying down successive layers of the solid material. With 3D printing, various complex designs can be turned into reality through 3D printing. The development of design through additive manufacturing saves money and mitigates the risk of waste of investment if the design is not compatible.
