3D printing at wafer scale
7,200 microlenses, precisely aligned on an 8-inch wafer
Nanoscribe presents aligned 3D printing at wafer scale, showcasing an 8-inch wafer with 7,200 precisely aligned, aspherical microlenses. This benchmark exhibit demonstrates aligned 3D printing on large, pre-patterned substrates, enabled by the new 150 × 150 mm² stage.
The printed 8-inch wafer showcases how aligned 3D printing supports wafer-level integration of freeform micro-optics, opening new pathways for wafer-scale batch production and wafer- and chip-level photonics manufacturing.
