3D which means three Dimension object which we can fell. 3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object, with material being added together (such as liquid molecules or powder grains being fused together), typically layer by layer.
3D printing, also known as additive manufacturing, is a method of creating a three dimensional object layer-by-layer using a computer created design.
3D printing is an additive process whereby layers of material are built up to create a 3D part.
The reasons there are different types of 3D printers and printing processes are similar to that of the 2D printers we’re so familiar with. It all comes down to the following six considerations:
Printer cost
Print quality
Print speed
Printer capability
Practicality
User expectations
Fused deposition Modeling
Fused Filament Fabrication
Stereolithography
