The aim of this work was to fabricate LiO2-ZrO2-SiO2-Al2O3 (LZSA) glass-ceramics laminates by laminated object manufacturing (LOM) and to characterise some properties of the laminates before and after sintering. Correlations between green tape properties, produced by aqueous tape casting, and the green and sintered laminate proper-ties were also determined. Processing optimisation was based on a factorial design. The microstructure of the LZSA glass-ceramic laminates showed a homogeneous distribution of porosity and the main phases were identified as being P-spodumene and lithium metasilicate. Laminates with a 0 degrees/90 degrees layer orientation attained a significantly higher bending strength of 120 MPa compared to 70 MPa for the 90 degrees/90 degrees orientation.
