Creation of Multi-functional Hybrid Devices/Structures by Three Dimensional

Integration of Individual Components using 3D Printing

Princeton Docket 13-2861-1

Researchers at Princeton University have developed a novel process to provide three dimensional manufacturing of object containing various functionalities including light emitting diodes, transistors, biological tissues, and mechanical scaffolds etc. in a precise 3D architectural geometry prescribed by a CAD file from materials of various properties and functions, including electronic, mechanical, and biological functions.  Princeton is seeking a commercialization partner to license the technology.

The current technologies used in the industry that are intended to achieve material integration provide this only in a two dimensional fashion. This process based on simultaneous 3D printing presents a novel concept of attaining a seamless three integration of components of various functionalities when printed from component materials. This enables hybrid 3D printed devices/structures having multiple functionalities offered by its component units. A major advantage of this process is that since the integration of various components is achieved during their manufacturing to form the final device/structure, as opposed to making the components first and then assembling, this process offers a unique seamless merging of its components and potential for unique architectures.

It is anticipated that this method could be used in creation of novel hybrid devices/structures that exhibit multiple functionalities. For example, it can be used to create of a true bionic organ made by the seamless 3D integration of biological cells forming tissue with electronic components such as light emitting diodes and transistors.
