| Abstract: | A processing algorithm for freeform fabrication of
heterogeneous structures is presented. The algorithm was
developed based on the heterogeneous fabrication structural
model, which was constructed from the STL based multi-material
volume regions and with material identifications. The reasoning
Boolean operation based modelling approach was used to
construct the heterogeneous CAD assembly and to output the
needed STL format. Procedures for generating the database
hierarchy and the storage of the heterogeneous structural
model, and derivation for developing the processing algorithm
for layered fabrication of heterogeneous structure are presented.
The developed algorithm was applied to a heterogeneous
structure consisting of two discrete material volumes, and the
detailed processing path is described. |
