Methods to Improve Surface Finish of Parts Produced by Fused Deposition Modeling
نویسنده
چکیده
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 conventionally used in investment casting. Therefore to use plastic patterns instead of wax, a technique is required to improve the surface finish of the FDM parts. It has been found that there are various methods to improve surface finish of plastic patterns made by FDM. These methods have been reviewed in this paper.

Some Investigations Regarding the Surface Treatment of Ultem*9085 Parts Manufactured with Fused Deposition Modeling
Fused Deposition Modeling (FDM) parts are typically subject to process-related rough or wavy surfaces, with stair-stepping effects whenever the parts produced have sloped or rounded part geometries; however, the level of optical quality frequently required demands that parts feature a smooth surface. In this paper, the results of a high-energy finishing process, which uses a disc finishing unit...

Fused Deposition Modeling (FDM) parts are prone to process-related rough and wavy surfaces with stair-stepping effects whenever the parts produced have sloped or rounded geometries. These stair-stepping effects can be reduced by using a smaller slice height, but complete elimination is not possible. In this paper, FDM parts manufactured with the material ABS-M30 are finished using mass finishin...

Rapid prototyping (RP) process is inherently performed by layered manufacturing. The surface finish of the RP part is inevitably excessively rough. In this study, aluminum filled epoxy resin is used as a filler to improve surface quality of wax injection tool fabricated by fused deposition modeling. The average surface roughness of wax patterns can be drastically reduced from 1710 μm to 276 μm....
