In order to explore the feasibility of fabricating prosthetic ear with selective laser sintering method,layer-milled graphic technique is used to acquire the data of left ear. A 3-D digital model of left ear is produced. A digital model of right ear is produced by mirror imaging. Selective laser sintering (SLS) and wax powder PCP1 are chosen to fabricate a wax right ear model. The skin texture and pore are sculped on the wax model and the prosthetic ear is made by silicone elastomer. The result shows that the right ear wax model is not only distinct and precise,but also can be replaced by silicone elastomer directly. This study suggests that SLS and the new wax powder PCP1 can be used to fabricate prosthetic ear. Comparing with conventional manual methods,the new fabricating method shortens time and simplifies manufacturing steps. This digital and model-free manufacture provide can a new method for the automatic manufacture of maxillofacial prostheses,and will lay the foundation for the clinical application in the future.
