Portable devices

Portable devices When describing hardware that is portable it

means something that is small and lightweight. Laptop computers are portable because they are easy to carry. Other portable devices include PDA's, hand-held computers and TabletPC's.Software can also be described as portable when it can be run on a variety of computers. The software does not require any particular hardware in order to operate.

3D PRINTER

• Additive manufacturing or 3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes. 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes).

• A materials printer usually performs 3D printing using digital technology. The first working 3D printer was created in 1984 by Chuck Hull of 3D Systems Corp. Since the start of the 21st century there has been a large growth in the sales of these machines, and their price has dropped substantially. According to Wohler's Associates, a consultancy, the market for 3D printers and services was worth $2.2 billion worldwide in 2012, up 29% from 2011.

• The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, engineering, construction (AEC), industrial design, automotive, aerospace, military, engineering, civil engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields. It has been speculated that 3D printing may become a mass market item because open source 3D printing can easily offset their capital costs by enabling consumers to avoid costs associated with purchasing common household objects.
