Investment Casting with Ice Patterns Made by Rapid Freeze Proto
نویسندگان
چکیده
One of the most promising applications of rapid freeze prototyping (RFP) is making metal parts by investment casting with the built ice parts. The integration of RFP and investment casting allows fast creation of complex net-shape metal parts directly from their CAD models. The advantages of doing so include no part geometric complexity limitation, no experience of parting line design and assembling needed, clean and low-cost of process operation, and good performance. In this paper, we will present our recent study on binder selection, slurry making, ceramic shell making, and the casting results of the metal parts.

متن کاملMethods to Improve Surface Finish of Parts Produced by Fused Deposition Modeling
Fused deposition modeling (FDM) is one of the rapid prototyping technologies that can use plastic material, which can be effectively used for making patterns for investment casting. The surface finish of the investment casting depends upon the surface finish of the pattern. But the surface finish of the parts produced by using FDM is not very good as compared to wax patterns, which are conventi...
