THREE-DIMENSIONAL PRINTING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240246147 titled 'THREE-DIMENSIONAL PRINTING

Simplified Explanation: The patent application describes a method for three-dimensional printing where a binding agent is selectively applied to build material layers to form a structure with voids.

• **Selective Application of Binding Agent:** The method involves selectively applying a binding agent to individual build material layers based on a 3D object model.
• **Formation of Voids:** By applying the binding agent and/or a void-formation agent to interior layers, voids are created in the structure.
• **Heating Process:** The intermediate structure is heated to form a 3D structure with void-containing breakable connections.

Potential Applications: This technology can be used in various industries such as aerospace, automotive, and manufacturing for creating complex structures with internal voids.

Problems Solved: This method allows for the creation of intricate 3D structures with voids, which was challenging to achieve with traditional manufacturing methods.

Benefits: The method offers increased design flexibility, lightweight structures, and the ability to create parts with customized internal features.

Commercial Applications: The technology can be applied in industries requiring lightweight yet strong components, such as aerospace for creating complex, optimized parts.

Questions about Three-Dimensional Printing: 1. How does the selective application of binding agents contribute to the creation of voids in the 3D structure? 2. What are the advantages of using void-containing breakable connections in the final 3D printed parts?

Original Abstract Submitted

in an example of a method for three-dimensional printing, a first amount of a binding agent is selectively applied, based on a 3d object model, to individual build material layers of a particulate build material including metal particles to forming an intermediate structure. the binding agent and/or a void-formation agent is selectively applied, based on the 3d object model, to at least one interior layer of the individual build material layers so that a total amount of the binding agent, the void-formation agent, or both the binding agent and the void-formation agent in the at least one of the individual build material layers is greater than the first amount. this patterns an area that is to contain voids. the intermediate structure is heated to form a 3d structure including a void-containing breakable connection.
