Research on mixture of PES/CaCO3 as 3D printing materials in restoring ancient architectural works in Vietnam

Abstract

In this study, we have used selective laser sintering (SLS) 3D printing technology with printing material is a mixture of Polyether sulphone resin (PES)/CaCO3 powder to recover the stylized dragon, lion, phoenix motifs and ancient works in Vietnam. The experiment has created a 3D product of lion mascot, with the result of mechanical properties tensile strength, flexural strength and impact strength average values, which are 8.08 MPa, 15.28 MPa and 3.09 KJ/m2, respectively. Experimental results show that the mixture of PES/CaCO3 powder is suitable for 3D printing materials in recovering the details and ancient works in Vietnam.
