Abstract

Effect of binder towards powder system had gained its importance lately towards 3D printing process. This research aim to investigate the effect of powder system developed from incorporation of PEG onto HAP powder for 3D printing application. Simple spray method was used incorporate mixture of PEG into HAP powder. Raw commercial HAP powder was determined by using particle size analyser. The morphology and crystallinity of raw HAP powder and powder mixture were characterised by using SEM and XRD analysis. Mean particle size of raw HAP was found to be 4.77 pm which is suitable for 3D printing and in line with SEM images. The powder was found in an agglomerated and small particle form. Incorporating PEG onto HAP powder exhibits no phase change or significantly influences the XRD peaks. Based on this study, it can be concluded that incorporating PEG onto HAP powder able to maintain the initial characteristic of HAP and can be work together as powder system.
