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

Abstract

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.
