Title: Innovations of Yan Zhang in Additive Fabrication
Introduction
Yan Zhang is an accomplished inventor based in Lowell, MA, with a notable portfolio of four patents. Her work primarily focuses on advancements in additive fabrication technologies, which have significant implications for manufacturing precision objects.
Latest Patents
One of her latest patents is a precision system for additive fabrication. This innovative approach utilizes jetting of cationic compositions alongside a non-contact feedback mechanism, such as optical feedback. By eliminating the need for contact to control the surface geometry of the manufactured object, this method accommodates the slower curing process of the cationic composition. It also ensures that the deposition processes are controlled according to real-time feedback during fabrication. This technique allows for the production of precision objects with desirable material properties, such as isotropic characteristics and flexible structures, which are often unattainable with traditional jetted acrylates.
Another significant patent involves thiol-ene printable resins for inkjet 3D printing. This composition includes a photopolymer that consists of various thiol and alkene monomers, along with a polymerization initiator. The specific thiol monomers used can include glycol di(3-mercaptopropionate) and trimethylolpropane tris(3-mercaptopropionate), among others. The alkene monomer is synthesized from an isocyanate moiety and a hydroxyl or amine functional allyl moiety, which can include compounds like allyl alcohol and allylamine. This innovative formulation enhances the capabilities of 3D printing technologies.
