Selective Laser Sintering of Alumina-Zinc Borosilicate Glass Composites using Monoclinic HB02 as a Binder

By Insup Lee, A. Manthiram and H.L. Marcus

Abstract

Selective Laser Sintering (SLS) process has been employed to fabricate alumina-glass composites using as an inorganic binder monoclinic HB02. Subsequent post-thermal processing of green SLS parts at various temperatures yielded glass-ceramic composites. The crystalline phases and microstructural evolution at each fIring temperature were identified by X-ray diffraction analysis and Scanning Electron Microscopy. The role of glass content, firing temperature, and alumina particle size on the densification and bend strength of fired samples were studied. In addition, further densification was made through infiltration of colloidal silica into the fIred, porous samples.Mechanical Engineerin
