3D printing involves the different processes where the material is joined or solidified under the computer control for creating a three-dimensional object. The material is fused or added together include the liquid molecules or powder grains. The 3D printing is used for both rapid prototyping as well as additive manufacturing. The objects being formed can be of any shape or geometry and are primarily produced using digital model data from either a 3D model or another form of the electronic data source.
