An approach of synchronizing linear stages and galvo-scanners in order to eliminate inherent weaknesses of each device while capitalizing on their strengths and produce millimeter-sized highly complex meso-scale structures retaining small (~μm) features is presented. We concentrate on results and discussion about the structuring rate of 3D laser lithography (3DLL), investigating the interplay between translation velocity, feature size and structuring rate. These effects are uncovered by fabricating resolution bridge structures and 1 mm length gradient chain-mail structure with ring sizes from 5 μm to 100 μm. Provided results give an insight on current state- of-the-art manufacturing throughput of 3DLL systems using scanner-stage synchronization and allow to project the technological limit of this technique.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
