SPIN expands a projection-based vat photopolymerization printer’s effective build area 4.8-fold, from 60.4 mm² to 290.5 mm², while maintaining microscale feature fidelity.
- Why it matters: Large-area projection VP printing is limited by fixed DMD pixel counts, forcing a trade-off between projected pixel size and printable area.
- What they did: The authors implement segmented projection image translation by applying controlled orbital translation to an off-axis objective lens in the optical infinity space, then print test features and 3D trusses.
- The result: The SPIN-enabled system yields isolated lines as thin as 9.8 ± 2.2 µm and truss features as small as 30 µm across stitched exposure fields, supporting scalable high-resolution printing.
