Plumajet Inc

Plumajet Inc is a materials science company that has developed a proprietary spray coating technology known as self-limiting electrospray deposition (SLED). This approach utilizes electric fields to guide micro-sized material particles to a target, enabling precise, uniform, and conformal coatings on complex 2D and 3D geometries. By operating under ambient conditions and achieving high deposition efficiency—often near 100 percent—the technology offers a scalable alternative to traditional methods like dip coating or vacuum-based deposition. It is compatible with a wide range of materials, including polymers, nanoparticles, and bioactive substances, and can be applied to various conductive substrates.

The technology is designed to solve challenges associated with coating small or intricate components where traditional methods are inefficient, wasteful, or difficult to automate. Potential applications span multiple industries, including medical device functionalization, such as applying drug materials to microneedles for individualized medicine, and industrial manufacturing, such as electrode protection, defect repair, and creating high-surface-area functional materials. Founded by Michael Grzenda, the company aims to provide a platform manufacturing technique that accelerates production while significantly reducing material waste and costs.
