ELECTROSPRAY EMITTERS, ASSOCIATED METHODS FOR THEIR USE, AND ASSOCIATED METHODS AND DEVICES FOR THEIR FABRICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240227237 titled 'ELECTROSPRAY EMITTERS, ASSOCIATED METHODS FOR THEIR USE, AND ASSOCIATED METHODS AND DEVICES FOR THEIR FABRICATION

The method described in the patent application involves filling a mold with a slurry, curing the slurry to create a cured piece, and then heating the mold to burn off the mold and binder of the slurry while maintaining the shape of the molded piece.

  • The mold is made from a material that vaporizes at a lower temperature than the melting temperature of the molded piece, ensuring the piece retains its shape during the burning process.
  • The mold can be fabricated using 3D printing with resin or polymer, allowing for complex shapes and designs.
  • The molded piece produced by this method can be a porous ceramic electrospray emitter, which may have a sharp tip for precise applications.
  • Two-photon polymerization 3D printing can be used to create parts of the mold with higher spatial resolution, particularly for intricate features like sharp tips.

Potential Applications: - Manufacturing of complex ceramic components - Production of electrospray emitters for various applications in fields like biotechnology and materials science

Problems Solved: - Maintaining the shape of intricate molded pieces during the mold burning process - Creating porous ceramic structures with sharp tips for specific applications

Benefits: - Allows for the fabrication of complex ceramic components with precise features - Enables the production of electrospray emitters with sharp tips for enhanced performance

Commercial Applications: Title: Advanced Ceramic Manufacturing Method for Precision Components This technology could be used in industries such as biotechnology, materials science, and electronics for the production of specialized ceramic components with intricate designs and sharp features.

Questions about the technology: 1. How does the use of two-photon polymerization in 3D printing enhance the fabrication of molds for ceramic components? 2. What are the specific advantages of using a mold that vaporizes at a lower temperature during the manufacturing process?


Original Abstract Submitted

a method for fabricating a molded piece includes filling a mold with a slurry, curing the slurry in the mold to create a cured piece, and heating the mold, with the cured piece therein, to burn off the mold and a binder of the slurry. the mold is fabricated from a material that vaporizes at a temperature lower than the melting temperature of the molded piece, thereby ensuring that the molded piece maintains its shape while the mold and binder burns off. the mold may be fabricated from a resin or polymer using three-dimensional (3d) printing. the molded piece may be a porous ceramic electrospray emitter. to create this emitter with a sharp tip, at least part of the mold may be fabricated using 3d printing based on two-photon polymerization, which has a higher spatial resolution than other types of 3d printing.
