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
