| Summary: | Selection of the most suitable Rapid Prototyping (RP) and manufacturing process for a
specific part creation is a difficult task due to the development of RP processes and materials. Most
current RP processes can build with more than one type of material. The paper presents the
evaluation on Acrylonitrile Butadiene Styrene (ABS) and Polylactic acid (PLA) part produced from
Fused Deposition Modeling (FDM) as a master pattern for Investment Casting (IC) process. The
main purpose of this research is to evaluate the dimensional accuracy and surface roughness for
hollow and solid part of FDM pattern for IC process with different layer thickness. The value were
taken for both before and after the casting process. Results show that model fabricated with hollow
internal pattern structure (ABS material) that produced by low layer thickness is better than other
models in terms of its dimensional accuracy (-0.19666mm) and surface roughness (1.41μm). Even
though the ABS built part performed better as the model, the PLA build part produces better overall
casting result. Final part fabricated with solid pattern (PLA material) that produced by high layer
thickness is better than other final parts which its dimensional accuracy (-0.12777mm) and surface
roughness (3.07μm) |
