Functionally graded materials (FGM) have recently attracted a lot of research attention in the
wake of the recent prominence of additive manufacturing (AM) technologies. The …

The direct metal deposition (DMD) process is drawing considerable contemporary interest
due to its capability to deliver “Art to Part”. DMD can reduce the lead time for a concept to …

Solid Freeform Fabrication (SFF) processes have demonstrated the ability to produce parts
with locally controlled composition. In the limit, processes, such as three dimensional (3D) …

An effective representation of additive manufacturing (AM) data is important for ensuring the
repeatability of AM processes and the reproducibility of AM parts. Recently, several …

With the recent development of Iso-geometric Analysis (IGA)(Cottrell et al., 2009) and
advanced manufacturing technologies employing heterogeneous materials, such as …

The representations of contemporary CAD systems do not provide or contain any
information with regard to the materials of the objects that the CAD system is used for the …

Since the dawn of civilization, mankind has been engaged in the conception and
manufacture of discrete products to serve the functional needs of local customers and the …

Heterogeneous objects, composed of different materials, are increasingly being used in
engineering applications. Also, a new fabrication method called Layered Manufacturing …

This paper proposes a new scheme for modeling heterogeneous objects. Concepts of
'grading source'and material parameters are introduced so that the material composition and …

Modeling of products (objects) form a critical task in design and manufacturing. CAD–CAM
techniques based on solid/geometric modeling have been developed for this purpose …
