Three-dimensional (3D) printing may be an additive printing process for manufacturing three-dimensional solid parts from digital models. 3D printing is commonly used for rapid product formation, mold generation, and master generation. 3D printing techniques are considered additive processes because they involve the application of successive layers of material. This is in contrast to conventional cutting processes which typically rely on the removal of material to produce the final part. Materials used for 3D printing typically require solidification or melting, which for some materials may be achieved using heat assisted sintering, and for other materials may be achieved using digital light projection techniques.
