Multi-fluid kit for 3d metal printing
The granted patent US12042858B2 introduces a multi-fluid kit designed for three-dimensional (3D) printing, comprising two distinct fluids. The first fluid contains a liquid vehicle that incorporates metal or metal precursor particles, while the second fluid consists of a liquid vehicle with latex polymer particles dispersed within it. The latex polymer particles range in size from approximately 10 nm to 300 nm, and the metal or metal precursor particles have a mean diameter between 1 nm and 1000 nm. The patent outlines various types of metal nanoparticles and metal oxide nanoparticles that can be utilized, including those made from nickel, silver, gold, and copper, among others. Additionally, the latex polymer particles can be selected from a range of compounds, including methacrylic acid and styrene derivatives.
The patent further details a method for printing a 3D object using this multi-fluid kit. The process involves depositing a metal powder build material in a powder bed and selectively applying the first and second fluids based on a 3D object model. This method includes multiple cycles of fluid application and powder deposition, followed by heating the powder bed to temperatures up to 200°C. After forming the object, it can be removed from the powder bed and subjected to additional heating, which may reach up to 500°C to thermally decompose the latex polymer particles and facilitate the binding of metal particles. The process can culminate in a sintering step at temperatures exceeding 800°C, enhancing the structural integrity of the printed object. The claims emphasize the versatility and potential applications of the multi-fluid kit in advanced 3D printing technologies.
