The present article describes selected aspects of investment casting technology for manufacturing of open-cell aluminium.The main focus is, among others, on the Diffuser precursor thickening.Two groups of total 30 samples were produced, basing on open-cell polyurethane foam used as the precursor.Each of the two sample groups was thickened with a different type of suspension consisting of carbonaceous substances and organic binders.The influence of the coating mixture 7 Piece Dining Set type was compared, leading to conclusions regarding the desired composition and fluidity of the suspensions.

Both sample groups of the obtained open-cell aluminium had stochastic cell distributions, the average pore diameter was 5.2 mm and the PPI index was 8.The apparent densities were respectively: 0.485 g/cm3 and 0.312 g/cm3, which reflected the impact of the precursor coating.

Additionally, samples from both groups differed in quality.
