3-D PRINTING TECHNOLOGIES APPLIED TO FOOD DESIGN.

The use of 3 - Dimensional printing,also known as additive manufacturing (AM) , technology in food sector has a great potential to fabricate 3D constructs with complex geometrics , elaborated textures and tailored nutritional contents . For this reason, 3-D technology is driving major innovation in food industry. Here ,we review the use of 3-D printing techniques to design food material properties behave during application of 3-D printing techniques. We suggest that the rational design of 3-D food constructs relies on three key factors:
1.) Printability
2.) Applicability
3.) Post processing
Especial emphasis is devoted to how the advantages and limitations of 3-D printing techniques affect the end use properties of the printed food constructs
