| Summary: | Fused deposition modeling (FDM) is currently one of the most used AM technologies and has
been around in various industries since its tremendous offering. Most semi-molten layered
thermoplastic surface often uneven, which lead to rough and poor surface finish. The FDM
process involves temperature gradient since the material extrude was in a semi-molten state.
The thermal stresses present and affect the surface quality. This paper proposes an idea of
using vacuum technology to reduce the “staircase effect” parts printed. The FDM machine
remains in a rectangular acrylic chamber, an oil-flooded-vacuum pump connected will absorb
the air inside the chamber until desire pressure while printing object. Mitutoyo SJ-301
portable surface roughness tester and optical microscope used to analyze the quality of surface
finish. Result reveal with vacuum technology, improve 9% from normal print. |
