How 3d Printing Works
Three-dimensional printing commonly known as 3d printing is the process of making physical objects from digital files. Materials are put on top of each other until the required object is built. Due to this successive laying down of materials, it is usually referred to as additive manufacturing. It combines the use of special printing materials and printers. It was developed to defeat the margins of two dimensional printers that were largely in use but could not satisfy various demands. The computers to which they are attached have a particular type of code to instruct the printers on what and how to print.
3d printers come at different sizes, designs and prices and are also used to accomplish various tasks. There are those designed for a home setting, office setting or industrial setting. Those for use at home are fairly cheaper than those used in industries. These variations ensure people get the printers of their choice depending on the amount of money they have or the intention for which they aim to use them for. This however does not mean that some are not efficient.
The 3d printers use different types of technology. One of the methods used is fused deposition modeling. Most people prefer using this kind of technology. Thermoplastic material is dissolved creating the layers. It then hardens up producing 3d objects.
Steriolithography is also a technology used in 3d printing. It was mostly employed in the first generation 3d printers. It combines the use of u.v rays and a photo-polymer such as resin. The rays are concentrated on the object that is to be formed. A computer is used to control these rays. A photo polymer is used to fill the object. The photo polymer hardens up when the rays are passed through it resulting in the formation of a 3d object.
Selective laser sintering is also another technology used. Laser beams of high power are used to aid information of the objects. Metal powder is also used. Objects are formed when the laser beams are focused on these powders. Selective laser melting uses the same process only that instead of metal powder, it uses liquid.
Laminated object manufacturing is also used in 3d printing. Paper is fused with plastic at high temperatures and pressure. When they fuse, a solid object is formed and can be cut into required shape.
3d printers are helpful in that people can create 3dimensional objects from anything. The objects made can either be toys or learning materials. The technologies can easily be comprehended by all. No advanced skills are required, only necessary knowledge to operate the printers and machines. It is therefore a technology that should be looked into further and developed. All companies that deal with the manufacture of objects should ensure that they have these printers in order to keep up with changes in demand.
A lot of websites that offer information on these printers have been set up.
