What is 3D Printing Technology ?

• 3D Printing technology is an additive manufacturing process used to construct a physical three-dimensional object from a digital Computer-Aided Design (CAD) model.

• The 3D printing concept was started by Dr. Hideo Kodama, a japanese whi filed the first additive manufacturing patent in 1981.

• 3D printing Technology is a technology that use filament to print an object.

• 3D Printing works by exposing a layer of photosensitive liquid resin to a UV-laser beam; the resin then hardens in the desired pattern, and the object is built layer by layer until it is complete.
