By directly printing functional materials, devices are more reliable, less costly, and offer improved aesthetics and ergonomics. Imagine integrating sensors on your device in locations where conventional technologies could never previously address; or, delivering precise doses of drugs to target areas knowing the exact orientation and location of your device.
Our proprietary "direct write" technology offers a superior alternative to screen printing electronics. It offers unmatched accuracy, repeatability, and thickness control for complex designs on irregular 3D surfaces. By utilizing precise electronic ink printing, designers can print electronics onto any substrate and add/enhance a functionality to their device, such as:
Printing electronics on medical devices, seamlessly integrating sensors, electrodes and RO markers on catheters, medical balloons and implants.
Flawlessly printing resistors on complex geometries.
Our printing capability allows for the integration of printed sensors onto endotracheal tubes for sensing temperature, nerve monitoring and patient monitoring. The result is a “smart tube.”
Traditional subtractive printing technologies create precious metal (gold, silver, platinum) waste which adds to product cost. Our additive printing capability eliminates precious metal (gold, silver, platinum) waste.

Conformal printing is a competitive advantage of Exxelia Micropen. Substrates may be hard, soft, or 3-D. Materials ranging in viscosity from 5 to 500,000 centipoise can be printed on the outside or the inside of a substrate. Printing characteristics include the ability to dispense linewidths down to 50microns and line spacing to 25microns with very low profiles.
Printed ablation features can be applied to deliver energy to a precise location. The same principles are utilized in cryo-ablation medical device printing.
Surgical safety is growing in importance in minimally invasive surgeries. Printing a radiopaque marker provides designers with greater flexibility than traditional placement of markers.
Designers can choose from conductive, dielectric, adhesive, and radiopaque inks to create functional elements designed to meet the application requirements.
