3D printers are a device that has recently seen a huge increase in popularity of the last few months or year. They are basically a print that creates the image in 3D using templates that specially designed and the items it prints are made out of a liquid plastic that solidifies quickly. They can not create anything too complex but the biggest ones can create objects that are a few feet long and a few feet tall. The print, well it can not make complex moving parts, can create parts of a kit that can be put to together to create something bigger that could be more complicated. They are available at a lot of different places and you can get them for a range of prices and sizes, as well as methods for printing and type of plastic it uses. There are 3D printers for commercial use as well as recreational use around the home.
There are a few printers that are extremely expensive that use lasers that can 3D print uses all kinds of materials like glass, plastic, rubber, and some metals. This are called SLS 3D printers. The materials it uses come in a powder form that is slowly put into position. Then the laser heats up the powder into solid object. This type of 3D printing takes a lot of time and energy. They are also expensive and because of the laser involved are used only for business that specialize and have the personnel required to operation one of the machines.
FDM printers are the most widely used 3D printers, but they can only use the special plastic as a building material. They have a hose with a special nozzle that slowly sprays the plastic out into the deserved shape. This printers can be used anywhere.
The last type of 3D printer is the SLA, which uses a tank of the plastic and a high powered light source. The tank is filled with the deserved amount of plastic and the light source melts certain spots in order to create a specific object. Because of its design this printers can only produce basic objects and can make anything too complex. They are one of the most inexpensive options available though and can be used and run into many environments.
Because of the increase in popularity of 3D printers there are more unique designs popping up, along with new uses and functions.
