3D micro-printing by 2D/3D image projections inside photo-resins

3D printing by photopolymerization is growing, and is now  industrializing. Only the slow technology of two-photon polymerization has addressed the micron and sub-micron XYZ resolutions needed for many applications.

Two French research laboratories have developed a photo-projector printer dedicated to real-time 3D micro-structuration on cm² surfaces or in mm3 volumes. Its unique technology is based on image projections inside ultrasensitive nonlinear photoresins. The 3D light exposure can either be generated by the scanning of 2D slice images or by the direct 3D holographic image of the target.

It uses conventional components, but with an unique light exposure strategy that maintains good Z resolution (< 10 µm).
