This research presents comprehensive assessment of the precision castings quality made in the Replicast CS process. The evaluation was

made based on quality of the surface layer, shape errors and the accuracy of the linear dimensions. Studies were carried out on the modern

equipment, among other things a Zeiss Calypso measuring machine and profilometer were used. Obtained results allowed comparing lost

wax process models and Replicast CS process.

The article presents an analysis of the applicability of the Replicast CS process as an alternative to the investment casting process,

considered in terms of the dimensional accuracy of castings. Ceramic shell moulds were based on the Ekosil binder and a wide range of

ceramic materials, such as crystalline quartz, fused silica, aluminosilicates and zirconium silicate. The linear dimensions were measured

with a Zeiss UMC 550 machine that allowed reducing to minimum the measurement uncertainty.
