What is the high-tech of 3D printing

Three-di-mensional printing is a process for making parts and structures using rapid prototyping techniques such as light curing and paper stacking. It works much the same way as conventional printers we're used to, except that conventional printing is two-dimensional and uses paper and ink.Called 2D printing, a 3D printer contains "printing material" such as liquid or powder, which is connected to a computer and controlled by the computer to build up layer upon layer of "printing material", eventually turning blueprints on the computer into actual objects, machine parts, structures and daily necessities.Today, this technology is used in many fields, such as clothing, building models, cars, chocolate, machinery parts, aerospace structural parts.

Simply, 3 d printing is divided into two steps, first of all, in need of spray forming area of special glue, then evenly sprayed with a layer of powder, powder glue will solidify cohere, no glue while retain the original state of loose, again and again to repeat this process, until the solid model are the same "print", it makes no difference,Because its layered processing process is very similar to conventional inkjet printing and printer, so it is called "printer".

3D printing technology is also known as additive manufacturing, additive technology (process), ASTM International (International) in the United States of America will be additive manufacturing and 3D printing in its related materials these two terms, namely, "additive manufacturing is also known as 3D printing, the use of computer aided design layer by layer preparation.Wikipedia says accuracy, repeatability and the range of materials have increased to the point where 3D printing is considered an industrial production technology known as additive manufacturing.Some people think additive manufacturing is the industrial version of 3D printing.

With the increase of material manufacturing is corresponding to the reduction of material manufacturing, parts of the conventional manufacturing technology is the reduction of material manufacturing technology, for example, the quality of the finished casting, die casting a net 10% 20% lighter than the input of raw material, or even more, and in the process of increasing material manufacturing, the quality of the workpiece is always on the increase, parts made with only a small amount (< 10%) for machining.
