Micro- and Nano-Scale 3D Printed Microlenses
The rise of micro- and nano-scale 3D printing is transforming the fabrication of microlenses, enabling breakthroughs in optics, biomedical imaging, and telecommunications. These miniature lenses are key to controlling light propagation, adjusting focal lengths, and shaping beam profiles in high-precision applications such as microscopic imaging, laser beam shaping, and optical sensing.
Traditional microlens manufacturing methods—like photolithography and micro-milling—deliver high precision but struggle with complex geometries, fast prototyping, and cost-efficiency. Micro- and nano 3D printing overcomes these limitations by offering exceptional resolution, customization, and rapid production capabilities.
What Is Micro- and Nano-Scale 3D Printing?
Micro- and nano-scale 3D printing is an advanced additive manufacturing technique that builds optical microstructures layer by layer. Unlike conventional subtractive methods, this approach allows for complex, mold-free designs and ultra-fine resolutions—often at the sub-micron or nanometer scale.
