Their research, published in Advanced Functional Materials, demonstrates that the precision spin coating process, previously considered unreliable on curved surfaces, can be accurately controlled and predicted. The coating profile remains unaffected by the printed staircases if enough liquid is applied, allowing the surface to be treated as smooth. The coating thickness can be controlled within 1 μm.

Researchers from Purdue University have addressed these challenges by developing a VPP-based lens printing process that minimizes lateral and vertical stair-stepping defects. This process integrates unfocused image projection and precision spin coating. By slightly defocusing the curing image during printing, lateral pixelation is reduced without sacrificing build size. The subsequent spin coating smooths vertical steps.

... lens), the focal length for the combined system is given by. The distance ... The magnification can be found by dividing the focal length of the two lenses.

Additive manufacturing has emerged as a promising alternative for fabricating optical components. Techniques such as material jetting and vat photopolymerization (VPP) offer high precision and speed, but achieving the necessary smoothness for high-quality lenses remains challenging due to the layer-by-layer nature of 3D printing.
