The Basis Process consists of
(A). scanning an object or to be filled defect to get the 3D printed product ;
(B). Making the 3D object from the scanned data digitally clearly showing different components of it and selecting the materials needed for each of the afor-mentioned components ;
(C). Slicing it digitally layer by layer showing the different components clearly ;
(D). Printing the layers one above another.
We might need different printer heads depending on different components. At the end , the layers need to be fused by special methods or due to the inherent nature of printing process to give us the fully made 3D object.
When the number of components is only one , this becomes very simple and used extensively for art , sculpture , machine parts etc. However , when we talk about tissue or organ printing , the number of components are more than one.
