Effects of aging on epoxy‐based rapid tooling materials

Xavier Ottemer, Jonathan S. Colton

This study shows the effects of aging on epoxy‐based rapid tooling materials. Two epoxy‐acrylate resins used for stereolithography and one aluminum powder‐filled epoxy used for…

Adaptive slicing with cubic patch approximation

Madhup Kumar, A. Roy Choudhury

In adaptive slicing, the number of layers is drastically reduced by using sloping layer walls. For both vertical (2.5D slices) and sloping (ruled slices) outer walls, the…

Effects of graphite powder on the laser sintering behaviour of polycarbonate

H.C.H. Ho, W.L. Cheung, I. Gibson

A non‐contact infrared temperature sensor was used to monitor the temperature–time relation of a point on the powder bed during laser sintering. The results were translated into a…

Investigation of the processing dependence of SL solidification residual stresses

D. Karalekas, D. Rapti

This paper presents an experimental study undertaken to determine the polymerisation‐induced residual stresses generated in stereolithography (SL) built test specimens, by using…

Anisotropic material properties of fused deposition modeling ABS

Sung‐Hoon Ahn, Michael Montero, Dan Odell, Shad Roundy, Paul K. Wright

Rapid Prototyping (RP) technologies provide the ability to fabricate initial prototypes from various model materials. Stratasys Fused Deposition Modeling (FDM) is a typical RP…

A CASD/CASM method for prosthetic socket fabrication using the FDM technology

Francis E.H. Tay, M.A. Manna, L.X. Liu

As an application of the computer aided design and computer aided manufacturing (CAD/CAM) technology in prosthetics, computer aided socket design and computer aided socket…
