Article: An experimental study on mechanical properties of UV cured 3D nanofibre printing materials Journal: International Journal of Microstructure and Materials Properties (IJMMP) 2024 Vol.17 No.1 pp.32 - 48 Abstract: To improve the mechanical properties of UV cured 3D printing materials after curing, this paper proposes a study on the mechanical properties of UV cured 3D nanofibre printing materials. The THBP modified nano TiO2 is prepared as a subsequent auxiliary material, epoxy acrylate (EA) as a prepolymer, dipropylene glycol diacrylate (DPGDA) as a monomer, and phenyl bis (lithium phenyl-2,4,6-trimethylbenzoylphosphinate) phosphine oxide as a photoinitiator. A UV curable 3D printing material was prepared by adding THBP modified nano TiO2 in different proportions, and analysing the mechanical properties of the materials prepared. THBP modified nano TiO2 with different proportions of self synthesised THBP was added in order to achieve the research of strengthening and toughening modification and to improve its mechanical properties. The experimental results show that when the content of TEBP-TiO2 is 5 wt%, the tensile strength and impact strength of the samples prepared after UV curing reach the maximum value of 51.3 MPa and 22.1 KJ/m2, respectively. With the gradual increase of the content of THBP-TiO2, the initial decomposition temperature and the maximum decomposition temperature of the materials increase. The residual mass of thermal decomposition is increased and the thermal stability is improved. Inderscience Publishers - linking academia, business and industry through research

Abstract: To improve the mechanical properties of UV cured 3D printing materials after curing, this paper proposes a study on the mechanical properties of UV cured 3D nanofibre printing materials. The THBP modified nano TiO₂ is prepared as a subsequent auxiliary material, epoxy acrylate (EA) as a prepolymer, dipropylene glycol diacrylate (DPGDA) as a monomer, and phenyl bis (lithium phenyl-2,4,6-trimethylbenzoylphosphinate) phosphine oxide as a photoinitiator. A UV curable 3D printing material was prepared by adding THBP modified nano TiO₂ in different proportions, and analysing the mechanical properties of the materials prepared. THBP modified nano TiO₂ with different proportions of self synthesised THBP was added in order to achieve the research of strengthening and toughening modification and to improve its mechanical properties. The experimental results show that when the content of TEBP-TiO₂ is 5 wt%, the tensile strength and impact strength of the samples prepared after UV curing reach the maximum value of 51.3 MPa and 22.1 KJ/m², respectively. With the gradual increase of the content of THBP-TiO₂, the initial decomposition temperature and the maximum decomposition temperature of the materials increase. The residual mass of thermal decomposition is increased and the thermal stability is improved.
