An improved distortion compensation approach for additive manufacturing using optically scanned data

This paper presents an improved mathematical model for calculation of distortion vectors two aligned surface meshes. The shows better accuracy when benchmarked to existing with exceptional conditions, such as sharp corners and small radii. was implemented into a developed compensation digital tool applied industrial component. component made Inconel 718 produced by laser powder bed fusion 3D printing technology. utilised compensate the original design geometry pre-distortion its using model. reduced from approximately ±400 µm ±100 challenging thin structure subjected buckling during build process.
