Latest Patents

Feinberg’s latest patents include cutting-edge technologies that enhance the capabilities of 3D printing. One notable patent, titled "Additive Manufacturing Support Material," outlines a process for producing gel microparticles that are consistent in size and morphology. This innovative approach employs coacervation to create large volumes of gel microparticle slurry, which can be easily scaled up in reactor vessel size. The unique properties of these particles, which can be repeatedly dehydrated and rehydrated, allow for storage in non-solvents like ethanol. Importantly, these gel slurries exhibit Bingham plastic behavior, enabling them to behave as solids at lower shear stresses and transition to a liquid state when critical shear stress is achieved. This rheological behavior can be tailored through adjustments in compaction processes, improving printing fidelity.

Another significant patent, "Additive Manufacturing Based on Fluid-Fluid Interface," describes a system and method for embedded printing in additive manufacturing. In this innovation, print materials are printed into a support material, with each having distinct fluid and solid phases. The transition of the print material from fluid to solid is governed by interactions with the support material, allowing for finer control over the diffusion rate during the printing process. This technology also enables the simultaneous printing of multiple materials into the support structure, enhancing the versatility of additive manufacturing applications.
