PROCESS FOR PRODUCING MOULDED ARTICLES FROM CARBON OR GRAPHITE BY 3D PRINTING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240286961 titled 'PROCESS FOR PRODUCING MOULDED ARTICLES FROM CARBON OR GRAPHITE BY 3D PRINTING
The process described in the abstract involves 3D printing articles made of carbon or graphite using a flowable polymeric mixture containing a UV permeable and polymerizable polymer or cellulose, along with a UV crosslinkable resin, sugar, and/or cellulose.
- The polymeric mixture is homogenized at room temperature or elevated temperature to achieve the desired consistency for 3D printing.
- The mixture is then filled into a 3D printer and layerwise printed into a shaped article while being exposed to UV radiation for crosslinking of the resin.
- After printing, the shaped article is cleaned and then stabilized in a furnace at a predetermined temperature to outgas volatile constituents.
- Subsequently, the shaped article undergoes high-temperature treatment in a furnace under protective gas for carbonization or graphitization.
Potential Applications: - Manufacturing of complex carbon or graphite articles with intricate designs. - Production of lightweight and durable components for various industries such as aerospace, automotive, and electronics.
Problems Solved: - Enables the efficient and precise production of carbon or graphite articles through 3D printing. - Provides a method for stabilizing and treating the printed articles to enhance their properties.
Benefits: - Cost-effective manufacturing of custom carbon or graphite articles. - Improved strength, durability, and thermal properties of the printed articles.
Commercial Applications: Carbon or graphite 3D printing technology for aerospace components, automotive parts, electronic devices, and industrial machinery.
Questions about the technology: 1. How does the UV crosslinkable resin contribute to the 3D printing process? 2. What are the advantages of using sugar and cellulose in the polymeric mixture for printing carbon or graphite articles?
Original Abstract Submitted
a process for 3d printing articles made of carbon or graphite includes producing a flowable polymeric mixture from a uv permeable and polymerizable polymer or cellulose and a uv crosslinkable resin, admixing the polymeric mixture with sugar and/or cellulose until the mixture has a consistency such that it can be filled into a 3d printer and processed thereby, homogenizing the mixture at room temperature or elevated temperature, filling a 3d printer with the mixture, layerwise printing a shaped article with simultaneous exposure to uv radiation for layerwise crosslinking of the uv crosslinkable resin, cleaning the shaped article, introducing the uv precured shaped article into a furnace and stabilizing the uv precured shaped article in air at a predetermined stabilizing temperature until all volatile constituents have outgassed from the prefabricated shaped article and subsequently high temperature treating the shaped article for carbonization or graphitization in a furnace under protective gas.
