Viscosity modulation by camphor during stereolithography printing of advanced ceramic materials
Sokola, Patrik ; Roleček, Jakub (oponent) ; Salamon, David (vedoucí práce)
This bachelor's thesis deals with the preparation of printing suspensions containing ceramics, their subsequent printing and evaluation of the properties of sintered ceramics. In the preparation of the printing suspension using zirconium powder stabilized with yttrium, the influence of the viscosity modulator, in particular the camphor, on the properties of the suspension and the final microstructure of the extruded and sintered objects was investigated. Samples with different contents of ceramic particles were prepared and the effect of camphor on the rheological properties of the suspension was determined. It has been found that camphor always has a positive effect on reducing the viscosity of a selected volume of ceramic, and the maximum amount of zirconium powder in the epoxy resin has been determined to make the suspension usable for stereolithographic printing. After printing, the density of the samples, their porosity, particle size, defects in the microstructure, visual quality and percentage shrinkage were evaluated. The camphor samples showed better properties for different volumetric contents of zirconium ceramics for all the mentioned factors.
