The Idea

ChromaNanoTech has developed a patented light absorbing additive based on organic cyanine dyes bound to metal oxide nanoparticles. This composite dye/nanoparticle material can be used in a variety of light absorbing applications including: metal additive printing, selective light filtration, labeling, and passive solar films. 


Metal Additive Printing

ChromaNanoTech has investigated the potential of enhanced print speeds and surface finish of metal additive printed parts. This additive material is designed to increase the laser absorbance of the printed metal powder, greatly increasing the overall heat transfer to the system, increasing print speeds to over 20% and a reduction in the surface roughness by 50%. This enables a faster printed part that requires less post processing. 

Selective Light Filtration

ChromaNanoTech can produce optically absorbing nanomaterials to selectively filter light based off of the application requirements. Some applications include laser protective eye ware, display filtering and fiber optics. These materials would gain the benefit of being nanosized, high surface area that is easily dispersed and maintain high optical absorption.


ChromaNanoTech has investigated the potential to generate unique visible or invisible nano labeling systems using ultraviolet, visible or near infrared absorbing nanoparticles. These systems can be incorporated into an ink media for marking while maintaining a unique signature. The labeling materials can also be incorporated into a plastic media during extrusion or as part of a 3D printed part and survive processing up to 300 C.

Passive Solar Window Films

ChromaNanoTech's optical absorbing material can be extruded as part of a window film with enhanced infrared absorbing qualities. This allows the window film to absorb a portion of the heat component of sunlight that is transmitted through the window while maintaining high optical clarity. The tech lowers the room heat, taking off burden from AC units and decreasing monthly energy requirements to cool a room.
