Laboratory for multiscale mechanics (LM2)

Polytechnique Montréal, Montréal, Québec
What the facility does

Micro-fabrication of advanced materials

Areas of expertise

The Laboratory for Multiscale Mechanics has developed an expertise in the fabrication of 3D microstructures. Daniel Therriault’s research team aims to design new materials and integrates them into mechanical systems by using new microfabrication and nanofabrication techniques. Despite the advanced progress in recent years in manufacturing of 3D-printers, big challenges remain in making structures in micro/nano scale and in printing different materials with the desired electrical or mechanical properties. LM2 research team use I & J Fisnar and a custom made Micos nano station to make free-form 3D microstructures which is not possible to be made by 3D printers available in the market. These microstructures have been used for different applications such as MEMS, micro-antennas and lab-on-chip. LM2 group is also working on manufacturing new types of conductive materials useful for 3D printing of microstructures applicable in the field of microelectronics and sensors.
