Engravography is a name created by Mr. Soheil Chodry the owner of Engravography Co. established in 2017 meaning engraving 4D pictures. 4D pictures as the name show is a picture with 3D technique but at the first look you are not able to see the details in the picture. actually in 3D mode the picture is totally unrecognizable but with the addition of an outer source which is Light in our case, the details of the picture comes out and you can see the details of the pictured engraved clearly. As known 4D technique could be light or heat which makes the unvisible picture visible. this is for the first time that 4D name is given to a picture.

4D 4-dimensional printing (4D printing; also known as 4D bioprinting, active origami, or shape-morphing systems,) uses the same techniques of 3D printing through computer programmed deposition of material in successive layers to create a three-dimensional object. However, 4D printing adds the dimension of transformation over time.[1] It is therefore a type of programmable matter, wherein after the fabrication process, the printed product reacts with parameters within the environment (humidity, temperature, etc., LIGHT here in our case ) and changes its form accordingly. The ability to do so arises from the near infinite configurations at a micrometer resolution, creating solids with highly engineered molecular spatial distributions[2] and thus allowing unprecedented multifunctional performance. 4D printing is a relatively new advance in biofabrication technology, rapidly emerging as a new paradigm in disciplines such as bioengineering, materials science, chemistry, and computer sciences.
