Multimaterial 3D Printer Developed For Creating Flexible Devices

Scientists have developed a new 3D printer that uses multi-wavelength lasers to create a highly porus graphene from polyimide and graphene oxide. The resulting structure is lightweight, conductive, and can be applied to flexible substrates such as plastics, enabling flexible devices.

The research is being conducted by scientists from Nanyang Technological University in Singapore, Panasonic Factory Solutions Asia Pacific, and the Singapore Center for 3D printing.

The manufacturer Jabil has shown interest in the new printer. The company aims to integrate 3D printed graphene electronics into a smart infusion system. A printed sensor embedded in an IV fluid bag would monitor the status of the IV drip, enabling the system to regulate pressure flow and temperature and transmit information to medical personnel.

The research team has also tested the possibility of integrating 3D printed components into the fabrication of electronics such as pressure sensors and heaters. The NTU-Panasonic team believes that the newly created 3D printer offers a level of flexibility and functionality unmatched by other similar products in the market. The project members said the innovation has the potential to revolutionise the field of 3D printing and open new possibilities for new product design and innovation.

The collaboration between NTU and Panasonic to develop the new multi-material printer began in 2016. Panasonic has set up a new facility for laser-based manufacturing systems at its research hub in Singapore, which will enable further trials of concepts using components fabricated by the multi-material printer.
