Abstract

Laser two-photon polymerisation is a 3D printing technique based on the process of two photon absorption, where a photosensitive molecule becomes a radical upon absorbing two photons with double the wavelength of its absorption peak. By moving the sample relative to the laser focal point, 3D structures with sub-micron features can be fabricated from a variety of materials. Here, we present a novel organometallic polymer biomaterial composed of aluminium isopropoxide, methacrylic acid and 3-methacryloxypropyltrihydroxysilane. We describe the preparation, fabrication, development aspects of this material and characterise some structures fabricated directly from computer-aided design (CAD) files using scanning electron microscopy (SEM).
