Modeling the shape of additive manufactured parts

The additive manufactured parts can be made by the use of suitable layer thicknesses ofthe polymer in order to respect the requirements of a refined geometry and of a surface appearanceof the physical object that should be as similar as possible to the original CAD model. An otherimportant variable is the digital datum that can represent a key variable of the realizationprocedure. The methodology proposed and followed in the present investigation got the objectiveto get a physical model, through the information obtained by a 3D scanning device, taking intoconsideration not only the digital treatment but also the building direction to guide the FDM layerdeposition in order to realize the required surface appearance. The profiles of the specimen in thedigital environment were compared to each other before realizing. The physical object obtainedafter digital treatment was similar to the one obtained by the original CAD.
