Latest Patents

One of Andrew Hudson's latest patents is for an "Additive Manufacturing Support Material." This patent describes a process for producing gel microparticles that are consistent in size and morphology. The process utilizes coacervation to create large volumes of gel microparticle slurry, which can be scaled up by increasing the reactor vessel size. These particles can be dehydrated and rehydrated based on environmental conditions, allowing for storage in non-solvents like ethanol. The gel slurries exhibit Bingham plastic behavior, acting as a solid under low shear stresses and transitioning to a liquid state when a critical shear stress is reached. The rheological properties of these slurries can be fine-tuned by adjusting compaction processes, such as centrifugation force, to modify the yield-stress. This innovation enhances the fidelity of FRESH printing by utilizing narrower particle distributions and reduced sizes.

Another notable patent is focused on "Additive Manufacturing Based on Fluid-Fluid Interface." This document outlines systems and methods for embedded printing in additive manufacturing. In this process, a print material is introduced into a support material, with both materials having distinct fluid and solid phases. The print material transitions from a fluid to a solid phase through fluid-fluid interactions with the support material. Parameters of the support material can be adjusted to control the diffusion rate of the print material, ensuring it remains below a specified threshold. This method allows for the simultaneous printing of multiple materials into the support structure.
