Abstract According to the requirement of heterogeneous object modeling
in additive manufacturing (AM), the Non-Uniform Rational B-Spline
(NURBS) method has been applied to the digital representation of heterogeneous object in this paper. By putting forward the NURBS material
data structure and establishing heterogeneous NURBS object model, the
accurate mathematical unified representation of analytical and free heterogeneous objects have been realized. With the inverse modeling of heterogeneous
NURBS objects, the geometry and material distribution can be better
designed to meet the actual needs. Radical Basis Function (RBF) method
based on global surface reconstruction and the tensor product surface
interpolation method are combined… More >
