It seems like 3D printing is more often than not scaled on the macro side of things, like the world's tallest 3D printed building that we covered recently, but now and then we get to see things from a micro perspective. Today we've got a project to share put together by a team of scientists that have managed to 3D print structures that are so small, you need a microscope to see them. The process creates what the team refers to as scalable phononic metamaterials.
One of the scientists on the team recently shared a post to Reddit answering questions about the development. The setup uses lasers to 3D print extremely small structures that can be fine-tuned in the design process to target specific frequencies for sound dampening. The laser used to polymerize the material when printing is produced with a beam ten times thinner than a human hair.
The team has experimented with several different structure designs, ensuring there's plenty of room for further experimentation and customization in the future. The final material can be used in a wide variety of places that make the technology a possible game changer in the world of sound control.
The team provides examples like medical-based use cases or even large-scale applications to dampen noise on a much bigger scale for buildings. This proof of concept requires a special setup at the moment and isn't something that can be replicated on your standard 3D printer. But that doesn't mean we won't see more microscopic 3D printing in the future.
