Optomec, an Albuquerque-based supplier of production-grade additive manufacturing systems for 3D-printed electronics and 3D-printed metals, announced its aerosol jet technology can enable 3D polymer and composite structures to be printed at the micron scale with embedded electronics. The company says this technology is targeted to the electronics and bio-medical industries.

This new capability is enabled by combining Optomec’s aerosol jet technology for fine feature printing with a proprietary in-situ curing capability for rapid on-the-fly solidification. This Optomec method relies on both local deposition and local curing.

“This breakthrough in 3D printing technology extends additive manufacturing to the creation of micron scale, free-form polymer structures and smart devices,” said Mike O’Reilly, Optomec director aerosol jet product management. “Early adopter customers have already developed innovative applications for smart devices and micro-fluidic applications. We continue to place emphasis on innovation such as aerosol jet 3D micro-structure printing to address our customer’s next generation product development challenges.”

Using this process high aspect ratio, free-form 3D structures can be printed at the micron-scale, without the need for support structures, from materials including photopolymers and certain composites. Additionally, the resulting structures can be metallized with conformal 3D conductive traces and printed functional components, such as antennas and sensors, to create fully functional 3D components all in one manufacturing machine. 

Aerosol Jet 3D micro-structure printing is capable of ultra-high resolutions with lateral features sizes down to 10 microns, and lateral and vertical build resolutions from 1 micron to 100 nanometers respectively. Aspect ratios of more than 100:1 have been achieved. Additionally, such 3D micro-structures can be printed onto existing components and products, such as semiconductor chips, medical devices or industrial parts.
