Usage of accuracy models in stereolithography process planning

Charity Lynn‐Charney, David W. Rosen

Determining whether a set of tolerances on a part can be met by a rapid prototyping (RP) machine is often difficult. To achieve a set of tolerances as closely as possible…

Reverse engineering of clear solids using refractive index matching

Jon Christensen, Amit Bandyopadhyay

A novel approach is used to reverse engineer polymeric parts in a low cost, non‐destructive manner. Solids created from polymers with an index of refraction matching that of an…

Titanium alloy powder preparation for selective laser sintering

B. Engel, D.L. Bourell

Selective laser sintering (SLS) is a solid freeform fabrication process whereby a part is built layerwise by scanning a powder bed. The processability of metal powder varies…

Mechanical properties of short‐fibre layered composites: prediction and experiment

G. Zak, M. Haberer, C.B. Park, B. Benhabib

As a way of enhancing the mechanical properties of photopolymer‐based parts produced by layered manufacturing (LM) techniques, the use of short glass‐fibre reinforcements has been…

An integrated CAD system for design of heterogeneous objects

Srinivas Bhashyam, Ki Hoon Shin, Debashish Dutta

Computer aided design systems are routinely used by designers for creating part geometries. Interfaces to computer aided analysis and manufacturing are also commonplace enabling…
