Latest Patents

Among his latest patents is an "Apparatus and method for temperature controlled cold spray." This innovative technique enhances cold spray deposition conditions for additive manufacturing. It utilizes an in-situ temperature feedback controller, which incorporates a remote instantaneous temperature sensor to provide surface temperature measurements. A long pulse laser is employed for heating, allowing for precise control over deposition conditions and yielding predictable deposition properties.

Another significant patent is for "Manufactured metal objects with hollow channels and method for fabrication thereof." This method involves creating a hollow structure in an additively manufactured object by using a sacrificial metal filler with a melting point of 350°C or less. The process includes cold spraying a metal layering material over the sacrificial filler and base material. The sacrificial filler is then melted away, leaving a hollow structure without damaging the surrounding materials.
