Rapid Prototype polymer resin models produced by Stereolithography have, by the \nnature of the process, a relatively poor surface roughness, particularly on concave and \nconvex surfaces. In many cases this is unacceptable, and slow and tedious manual finishing \ntechniques are often used to improve the surface. \nAn investigation has been conducted into a range of automated finishing techniques \nwith the aim of producing an acceptable surface roughness. This paper presents the results \nfrom two techniques, Vibratory Bowl Abrasion and Ultrasonic Abrasion using components \nmade from Ciba-Geigy XB5081-1 and XB 5143 resins. \nInitial results from Scanning Electron Microscopy and surface topography analyses \nsuggest that both techniques are capable of improving the model surfaces.
