Two-photon direct writing is widely used for fabrication of the three-dimensional functional microstructures with resolutions in the range of a few hundreds of nanometers. Variants of hierarchical three-dimensional meshed microstructures are recurrent in MEMS applications, photonics and biotechnology. A typical study of any applications would need tens of such structures. Most of the current fabrication techniques involve a layer by layer construction of hierarchical structures. This leads to long fabrication times often detrimental to the success of the study. Here we demonstrate a new scheme of scanning vertical walls of array structures called longitudinal scanning. This process speeds up the fabrication of hierarchical three-dimensional meshed microstructures up to 70 times compared to current methods leading to high throughput production of such structures. This opens such structures to widespread applications
