What is 3D Printing?
3D printing refers to processes used to synthesize a three-dimensional object in which successive layers of material are formed under computer control to create an object.Objects can be of almost any shape or geometry and are produced from digital model data 3D model or another electronic data source such as an Additive Manufacturing File (AMF) file.
Where can 3D printing be used?
Education and research
3D printing, and open source 3D printers in particular, are the latest technology making inroads into the classroom.3D printing allows students to create prototypes of items without the use of expensive tooling required in subtractive methods. Students design and produce actual models they can hold. The classroom environment allows students to learn and employ new applications for 3D printing.RepRaps, for example, have already been used for an educational mobile robotics platform.
The use of 3D scanning technologies allows the replication of real objects without the use of moulding techniques that in many cases can be more expensive, more difficult, or too invasive to be performed, particularly for precious or delicate cultural heritage artifacts where direct contact with the moulding substances could harm the original object's surface.
Domestic 3D printing was mainly practiced by hobbyists and enthusiasts. However, little was used for practical household applications, for example, ornamental objects. Some practical examples include a working clock and gears printed for home woodworking machines among other purposes.Web sites associated with home 3D printing tended to include backscratchers, coat hooks, door knobs, etc.3D printing is now working its way into households, and more and more children are being introduced to the concept of 3D printing at earlier ages. The prospects of 3D printing are growing, and as more people have access to this new innovation, new uses in households will emerge.
