“Two-Photon Lithography” Makes a Giant Leap Forward

Scientists and researchers at the Vienna University of Technology have made a major breakthrough in speeding up the “two-photon lithography” method of rapid prototyping. “Two-photon lithography” also known as “Two-Photon Polymerization” (2PP) is capable of rendering objects with a resolution measurable in nanometers. In the past this method of rapid prototyping was extremely time consuming. Professor Jürgen Stampfl, a researcher associated with the project commented, “Until now, this technique used to be quite slow… The printing speed used to be measured in millimeters per second – our device can do five meters in one second.”

This breakthrough means that extremely precise biomedical products can be produced at volumes that make them economically viable. One such product that requires extreme precision in its manufacturing is a micro-valve “designed to prohibit the reversal of blood flow in human veins”.  With the further perfection of this technology new methods of tissue engineering and drug delivery may be possible.
