...Yuna Hu; Vincent Y. Blouin; Georges M. Fadel Rapid prototyping (RP) technology, such as laser engineering net shaping, can be used to fabricate heterogeneous objects with various levels of gradient variations in material composition. These objects are engineered to achieve a potentially enhanced...

... metal, wood plastics, plaster, as well as rapid prototyping materials. The surface finish of the master pattern should be of high quality, since the silicone mold produces exact replicates, which is comparable to injection molding ( 19 ). The mold is produced by fitting the pattern with a casting gate...
