The people that engaged in the construction and design industry, more familiar with 3D printing technology, because they often use a rapid prototyping technology, to show the design of the prototype production for customer.In the past, the production of this prototype is very troublesome, because factory first need to make a mold, and then cast the material inside, so that the prototype can be produced. But when the factory is finished, the mold becomes useless. This mode of production wastes raw materials, and the production costs are naturally high. The cycle of required production is also long.3D printing is considered distinct from traditional machining techniques,which mostly rely on the removal of material by methods such as cutting or drilling.
3D printing is achieved using an additive process,where successive layers of material are laid down in different shapes.3D printers have a considerable degree of excellence, it can be directly operated to finish the prototype design.No need to make the mold of this step, customers can save more time,factories can save more costs, while the objects produced can be more accurate in accordance with design drawings. The reason is that 3D printer can "print" the object directly, first of all, people can create a three-dimensional design through computer, then the printer will divide the three-dimensional prototype "slice" into layers, and start working. The raw materials, according to design layer after layer of superposition,are finally shaped.Now there are more and more raw materials to be used, including resins, plastics, ceramics, metals and so on.The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture,construction,industrial design,automotive,aerospace,military,engineering,dental and medical industries,biotech,fashion,footwear,jewelry,eyewear,education,geographic information systems,food,and many other fields.3D printing technology has been around since the 1980s,it was not until the early 2010s that the printers became widely available commercially.
A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control.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.The material used by the 3D printer is not the ink in the inkjet printer, but some of the materials that can be reacted to the raw material.One study has found that open source 3D printing could become a mass market item because domestic 3D printers can offset their capital costs by enabling consumers to avoid costs associated with purchasing common household objects.
