3D meso-scale structures, that can reach up to cm in overall size but retain micro- or nano-features, proved to be promising in various science fields from micro-mechanical metamaterials to photonics. In this work we present an approach of synchronizing linear positioning and galvo-scanning for efficient femtosecond 3D optical printing of objects at meso-scale. In such configuration linear stages provide stitchless structuring at nearly limitless (up to tens of cm) working area, while galvo-scanners allow to achieve translation velocities in the range of mm/scm/ s without sacrificing nano-scale positioning accuracy. The capabilities of this approach are demonstrated by fabricating mm sized but μm features retaining structures with free movable parts, scaffolds for cell growth, microlenses and photonic crystals. Provided results show that synchronization of this kind is crucial for an end goal of industrial-scale implementation of this technology.
