The paper addresses the development of laser based equipment to structure large surfaces (1×1×0.5m - 3×3×1.5ft) that are shaped in three dimensions. A mechanic-optical system to process curved surfaces with an acceptance angle of up to 267° is presented. The challenge is to control the combined motion of the beam delivery system with respect to distortion of the motifs and positioning tolerances. The project starting Technology Readiness Level (TRL) was 5. Currently the project is under development and at the end of September 2015 the project will reach TRL 7 after industrial-like environment testing. The proposed system will enable manufacturers to offer individualized marking for large products.
