For 15 years, Patrice Baldeck and Michel Bouriau led intense research and development at the Université Grenoble Alpes. They are working on a two-photon polymer 3D printing process that will form the basis of Microlight3D, which was founded in 2016.The process will become the first non-additive two photon polymerization direct laser writing technology. Microlight3D’s technology allows a laser to move freely in three dimensions, performing uninterrupted printing inside a polymer resist.
The benefits of this technology are many.It produces extremely high resolution and smooth surface finish comparable to injection molding.It also provides a lot of design flexibility and eliminates the need for post-processing.It's a quick technique that can produce sturdy parts of any shape - 100 times smaller than a single hair. These microscopic parts have a wide variety of applications, including in micro-optics, microfluidics, micro-robotics, metamaterials and cell biology.
Microlight3D is the only company to commercialize 3D microprinters that use sub-nanosecond lasers. Compared with the femtosecond laser, the nanosecond laser has long high energy pulses, which makes the polymerization process more efficient.
