An In-Depth Overview Of 3D Printing

3D printing is often referred to as additive manufacturing or rapid prototyping. It happens to be a manufacturing process that utilizes a layered printing process to transform computer generated 3D models into physical objects. Initially, it was back in the 90s when the techniques were devised so that relatively cheap prototype parts could be produced for automotive and industrial design work. However, with a decline in costs, 3D printing is making its way into an ever increasing range of industries.

Considering that it is cost-effective and versatile, the advent of rapid prototyping has the potential to be as game-changing and important as assembly line was when it was introduced years ago.

How does it work

 

Although there are several different methods to print 3D objects, but there is a relatively consistent basic procedure. In rapid prototyping, either a liquid or particle raw material is used to create three-dimensional objects.

The digital model is used as a guide by the 3D printer. Consequently, the raw material is deposited in microscopically thin layers, and as the layers are gradually built, the three-dimensional object begins to materialize. The thinness of the layers determines the amount of detail that a 3D printer can create. The raw material can be anything from ceramic powder to glass, metal, or synthetic resin.

Where is it applied?

Traditionally, 3D printing has been applied in automotive and mechanical design settings. With additive manufacturing, concept models can be produced inexpensively and quickly, and fit & functionality tests can be performed. The technology has even progressed to such an extent that now even small amounts of production quality parts can be printed.

However, in the past decade there has been a decline in the prices for raw materials and 3D printers, as a result of which doors have opened to non-industrial applications. There are hundreds of niches where 3D printing can be applied, but here are some currently typical applications of this technology:
Architectural visualization: It is possible to produce pre-viz models inexpensively and quickly.

Fine art: Jewelry making, sculpturing, and more.

Geospatial: It is possible to produce geographic and/or topological models directly from raw GIS data.

Healthcare: Custom implants, educational models, prosthetics. Currently, exploration is also underway for the possibility of organ printing.

 Retail/Entertainment: Figurines, toys, and more.

Conclusion

The cost of 3D printing depends on the size of the desired print, and the type of material being used for printing. Ultimately, transforming a 3D model into a real-world object is certainly worth the money especially if larger quantities are to be printed for commercial purposes.
