Absorptance of powder materials suitable for laser sintering

Nikolay K. Tolochko, Yurii V. Khlopkov, Sergei E. Mozzharov, Michail B. Ignatiev, Tahar Laoui, Victor I. Titov

The normal spectral absorptance of a number of metal, ceramic and polymer powders susceptible to be utilised for selective laser sintering (SLS) technique was experimentally…

A novel system for fused deposition of advanced multiple ceramics

M.A. Jafari, W. Han, F. Mohammadi, A. Safari, S.C. Danforth, N. Langrana

In this article we present the system that we have developed at Rutgers University for the solid freeform fabrication of multiple ceramic actuators and sensors. With solid free…

Characterization of the mesostructure of fused‐deposition acrylonitrile‐butadiene‐styrene materials

Jose F. Rodriguez, James P. Thomas, John E. Renaud

Fused‐deposition (FD) is a robotically controlled “fiber” extrusion process that produces a new class of materials with a variety of controllable mesostructural features related…

Smoothing STL files by Max‐Fit biarc curves for rapid prototyping

Bahattin Koc, Yawei Ma, Yuan‐Shin Lee

Presents a method of Max‐Fit biarc curve fitting technique to improve the accuracy of STL files and to reduce the file size for rapid prototyping. STL file has been widely…

Specifying non‐uniform cusp heights as a potential aid for adaptive slicing

Denis Cormier, Kittinan Unnanon, Ezat Sanii

Most adaptive slicing implementations assume a maximum allowable cusp height which applies to the entire part. Practically speaking, however, most parts do not have uniform cusp…

Stereolithographic (SL) biomodelling in palaeontology: a technical note

P.S. D’Urso, R.G. Thompson, W.J. Earwaker

Stereolithographic (SL) biomodelling is a relatively new technology that allows three‐dimensional (3D) computed tomography (CT) data to be used to generate accurate solid plastic…
