About FVMat

Filled Void Materials – FVMat LTD is a startup focused on novel meta-materials.

By using 3D printing, applied physics, computational simulations, and optimization, we are creating a new class of mechanical meta-materials. These materials have novel properties that go beyond what is found in nature and can be controlled by design.

FVMat specializes in meta-material research, fabrication, and computational physics; making reality out of theory, simulations, and experiments. We are able to develop a wide array of meta-materials applications that encompass several industries including aerospace and defense, automotive, healthcare, energy, and education.

We have an approved international Patent Cooperation Treaty (PCT) as well as multiple patents pending.
