3D Printing also known as Additive Layer Manufacturing is the process of creating three-dimensional solid object or any form of digital models. How it works is similar to a laser printer with the technique makes the object of a number of layer / layers, each of which is printed on each layer of this printing lainnya.Teknologi itself has actually been growing since about 1980, but not so well known until 2010an when this 3D printing machine introduced commercially. Historically the first 3D printer that works well created by Chuck Hull of 3D Systems Corp. in 1984. Since that time 3D printing technology is growing and is used in prototyping (model) and the broader industry such as in architectural, automotive, military, medical industry , fashion, geographic information systems to biotech (replacement of human tissue).

And Binder Direct 3D Printer
3D printers have a direct kind of work mechanism using inkjet technology. This technology has been around since 1960 when it was used on a 2D printer. Although inkjet technology used in the 3D printer works is almost similar manner when used in a 2D printer. Where inkjet move back and forth, taking out the liquid. And the difference is 2D inkjet printer just move back and forth or horizontally, while the 3D inkjet printer can also move vertically or diagonally while removing fluid but instead of ink as 2D printer but wax and plastic polymers.

Photopolymerization And Sintering
Photopolymerization if observed from its name comes from the word that means light and a photo polymer that has meaning plastic chemical compounds. So it can be said to be a kind of 3D printers that have a way of working with a drop of liquid plastic is then given in the form of ultraviolet laser irradiation. And during the irradiation process can change a liquid to a solid form.

While the types of sintering 3d printerin the working process involving solid particles given irradiation process. And such a process is commonly called Selective laser sintering (SLS), which processes 3D printers work using lasers to melt the plastic powder which is then melted and froze back form a printed layer. Type sintering is highly compatible for printing objects comes from the metal. Because the manufacturing processes in metals often requires a mechanism of liquid and solid form then solid again. And the benefits arising from the sintering process is a high degree of precision.
