The patent US12042982B2 outlines a method for producing three-dimensional shaped objects through a layered material application process. The method begins with the provision of geometry data for the object and a support part with a base surface. It utilizes a liquid or flowable first material that can be solidified, alongside a second material that is either liquid, paste-like, or powder-form, which possesses greater strength when solidified. The first material can be dissolved in a solvent. The process involves forming a negative-shape layer by applying the first material to the base surface, solidifying this layer to create a mold, and then filling the mold with the second material to form a shaped-object layer. The method includes steps for machining excess material, repeating the layering process, and dissolving the first material using a solvent.

Further claims detail the characteristics of the materials used, such as the viscosity and solids proportion of the first and second materials, and the application methods for both materials, including inkjet printing and selective coating. The patent also describes the use of gas pressure to control the flow of the second material and various techniques for filling the cavities created in the negative-shape layer. Additionally, it mentions the potential for using thermoplastics that liquefy upon heating and solidify upon cooling. The method allows for the rotation of the support part during material application and solidification, enhancing the production process's efficiency and precision. Overall, the patent presents a comprehensive approach to additive manufacturing, emphasizing the interplay between different materials and application techniques to achieve desired object properties.
