Accuracy evaluation of a new 3D photogrammetric position measurement system for 6D Printing

Abstract

Additive manufacturing has a great potential for modifying optics in a way that new functions, for example individual light distributions, could be realized by modifying the optical surface. The functionalization of the curved surface by multijet modeling is the goal of the 6D printing project (6D AF) at the Center of Optical Technology, Aalen University. To combine the coordinate systems of the printing unit, the printing table and the metrology unit a new photogrammetric position measurement system is developed and presented. First results of the accuracy in three axes are show and the improvement in motion is demonstrated.
