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: An artificial flower, plant, or other botanical is produced from an aqueous agar-based solidifying mixture. The artificial botanical may be colored as desired by adding one or more colorants. The artificial botanical may also be scented by adding a perfume, odorant, or other scent. Because the artificial botanical is produced using the aqueous agar-based solidifying mixture, no animal-based gelatin products are used. The artificial botanical may thus also be edible and satisfies vegan diets. The artificial botanical may thus also be flavored by adding a flavoring, such as fruit, concentrate, or sweetener. The artificial botanical may be all-natural and edible by adding mica powder as the colorant and by adding glycerin as the flavoring.
