Abstract: A novel technology to create 3D-printed objects that are extremely temperature resistant, mechanically robust, ultra-low-wear, and exhibit self-healing behavior. The material can be manufactured in a wide variety of process conditions and even used as a high-strength adhesive, enabling hybrid fabrication strategies. The gel precursor for this material is formed from two solids that react to create a high-performance polymer when heated. Unlike similar materials, these are solid at room temperature and form a printable gel when dissolved in a solvent. Addition of a secondary solvent to this gel modifies the solubility and creates a super-saturated fluid with tunable rheology. Once the gel material has been printed, it is allowed to dry via forced convection. This removes the solvent and leaves only the uncured polymer precursors. After the majority of the solvent has been removed, the material is heated to its cure temperature, at which point it melts, cures, and re-hardens. This process is then repeated for each subsequent layer deposited.

Abstract: The invention relates to a method for producing three-dimensional, preferably porous, hydrogel structures by means of layer build-up technique, wherein the method comprises the following steps. Providing (S1) of a liquid hydrogel solution, preferably a liquid alginate solution, and a, preferably transportable, sample carrier. Layerwise applying (S2) the liquid hydrogel solution onto the sample carrier in a temperature environment, the temperature of which is below the freezing point of the hydrogel solution, to produce a frozen 3D layered hydrogel structure. In order to increase advantageously the porosity of the 3D layered hydrogel structure, i.e. the proportion of small voids, cavities and/or depressions in the 3D layered hydrogel structure, the method according to the invention further comprises the step of drying (S3) of the frozen 3D layered hydrogel structure, e.g. by means of freeze-drying, to produce a porous 3D hydrogel structure. The invention relates further also to a device for the layerwise building-up of three-dimensional hydrogel structures.
