Overview of 3d Printing Technology for Rapid Prototyping
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object.3D printing is the process of being able to print any object layer by layer. The current generation of 3d printers typically requires input from a CAD program in the form of an STL file, which defines a shape by a list of triangle vertices. The vast majority of 3d printers use two techniques, FDM (Fused Deposition Modelling) and PBP (Powder Binder Printing).FDM works on an "additive" principle by laying down material in layers. One advanced form of 3d printing that has been an area of increasing scientific interest the recent years is bio printing. Cell printers utilizing techniques similar to FDM were developed for bioprinting. These printers give us the ability to place cells in positions that mimic their respective positions in organs.3D printing can speed up production. Prototypes can be made quickly this way. Prototypes can also be made in a less expensive way with 3D printing. By applying3D printing of structural electronics to expedite prototyping, the development cycle was reduced from weeks to hours.
