This research work discusses the quality assurance of 3D printed or additively manufactured metal products by stochastic finite element analysis considering uncertainties. The variability of the physical parameters of material and geometrical imperfections should be considered as well as the uncertainties in the boundary conditions in experiment or in practical use. In this paper, a dental prosthesis made by titanium alloy, Ti-6Al-4V, is studied. The elasto-plastic properties were measured by static tensile test using 3D printed dumbbell type specimens. The geometrical model was generated by micro-CT images of printed prosthesis. The experimental results were largely scattered but they were within the predictions when the uncertainties in the constraint condition was assumed. The presented numerical simulation will be useful for both design and quality assurance.
