Title: Innovations of Andrew Lee in Additive Manufacturing

Introduction

Andrew Lee is an accomplished inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of additive manufacturing, holding a total of 3 patents. His work focuses on developing advanced materials and processes that enhance the capabilities of 3D printing technologies.

Latest Patents

One of Andrew Lee's latest patents is related to 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 dehydrated and rehydrated based on environmental conditions. The gel slurries exhibit Bingham plastic behavior, allowing them to behave as solids under low shear stresses and transition to liquids when critical shear stress is reached. This innovative approach improves the fidelity of FRESH printing by allowing for a narrower distribution and reduced size of particles.

Another notable patent by Andrew Lee involves additive manufacturing based on fluid-fluid interface. This patent outlines systems and methods for embedded printing, where a print material is printed into a support material. Both materials have fluid and solid phases, and the print material transitions from fluid to solid based on interactions with the support material. The diffusion rate of the print material can be controlled, enabling multiple print materials to be printed simultaneously into the support material.
