SHEET LAMINATION ADDITIVE MANUFACTURING FOR HOLLOW SEALED GEOMETRIES WITHOUT INTERNAL SUPPORT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240246287 titled 'SHEET LAMINATION ADDITIVE MANUFACTURING FOR HOLLOW SEALED GEOMETRIES WITHOUT INTERNAL SUPPORT

Simplified Explanation: The patent application describes a system and method for additive manufacturing that allows for the creation of hollow volumes in a product without the need for build supports within the hollow volume.

  • The system includes a material handling device, a printer, a material delivery system, and an energy source.
  • The system feeds sheets, prints on the sheets, applies powder, builds a hollow volume, and consolidates the sheets into a product with a contiguous structure.

Key Features and Innovation:

  • Additive manufacturing system for creating hollow volumes without build supports.
  • Integration of material handling device, printer, material delivery system, and energy source.
  • Feeding sheets, printing, applying powder, building hollow volume, and consolidating sheets into a product.

Potential Applications:

  • Aerospace industry for lightweight components.
  • Medical field for customized implants.
  • Automotive sector for complex parts.

Problems Solved:

  • Eliminates the need for build supports in hollow volumes.
  • Reduces material waste in additive manufacturing.
  • Enables the creation of intricate structures.

Benefits:

  • Cost-effective manufacturing process.
  • Enhanced design flexibility.
  • Improved structural integrity of products.

Commercial Applications: Potential commercial applications include:

  • 3D printing services for various industries.
  • Manufacturing of specialized components.
  • Prototyping and rapid production services.

Prior Art: Readers can explore prior art related to additive manufacturing, hollow volumes, and build support removal in the field of 3D printing.

Frequently Updated Research: Stay informed about the latest advancements in additive manufacturing techniques, materials, and applications.

Questions about Additive Manufacturing: 1. How does the system ensure the consolidation of sheets into a product with a contiguous structure? 2. What are the specific benefits of creating hollow volumes without build supports in additive manufacturing?


Original Abstract Submitted

systems and methods are provided for building a product by additive manufacturing and creating hollow volumes without including build supports in the hollow volume for the layers above the hollow volume. an additive manufacturing cell includes a material handling device, a printer a material delivery system and an energy source to feed the sheets, print on the sheets, apply a powder on the printed sheets, build a hollow volume into the sheets and consolidate the sheets into a product with a contiguous structure.
