Two-photon polymerization is a nonlinear laser‐based additive manufacturing technique that employs tightly focused femtosecond pulses to initiate polymer crosslinking through simultaneous absorption ...

A research group led by Dr. Toru Ube at Chuo University enabled 3D-selective deformation of “photomobile polymer materials” with the aid of two-photon absorption processes. Spatial selectivity of ...

The multistep, two-photon-lithography-based additive manufacturing method forms intermediate products of blank polymer, Ni-infused polymer, and NiO while fabricating Ni nanopillars. (Credit: Zhang et ...

Building things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today's state-of-the-art in ...

Researchers unveil an optofluidic laser method that assembles micro- and nanoparticles in liquid, enabling multi material 3D microstructures and microrobots. (Nanowerk News) Building things so small ...
