The Design of Artificial Porous Human Bone and RP Procedure Simulation
In design of artificial bones, in order to make it live together with the human bone, it should has the same porous structure as the human bone. But the Brep or solid model can’t achieve this. By transforming the three direction DEXEL model of polyhedrons into its VOXEL model and setting transparency attributes of VOXELs, the porous structure of artificial bone could be designed. By merging the same attribute VOXELs along y axis, a big VOXEL is formed. By this big VOXEL, the once sintering procedure of RP laser head is simulated. Layer by layer, the whole product is produced. Under Java2.0 and Java 3D, these algorithms were tested and some design examples were given.
