3 Conclusion A zooming-focused MIP-VPP-based 3D printing process has been presented for optical lens fabrication. The zooming-focused MIP-VPP uses frustum layer stacking to reduce the staircase stepping and improve the surface roughness so microscale dimensional accuracy and nanoscale surface roughness can be achieved. Consequently, no post-processing, such as meniscus coating and surface polishing, is needed.
