Methods for three-dimensional printing - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240253309 titled 'Methods for three-dimensional printing
The patent application discloses methods for additive manufacturing of objects with polymeric foam by extruding a mixture of a base polymer and a foaming agent provided as feedstock material, mixing them in an extruder, depositing layers to form a 3D object, and activating the foaming agent to create the foam.
- Mixture of base polymer and foaming agent extruded to create objects with polymeric foam
- Independent mixing rotor used in extruder for thorough mixing
- Sequential deposition of layers to build a three-dimensional object
- Activation of foaming agent during extrusion or through a separate heating step
- Innovative process for creating objects with polymeric foam
Potential Applications: - Manufacturing of lightweight components in various industries - Production of custom-designed foam-based products - Prototyping and rapid manufacturing processes
Problems Solved: - Simplifies the production of objects with polymeric foam - Enables the creation of complex geometries with foam structures
Benefits: - Cost-effective manufacturing process - Lightweight and durable foam-based objects - Customizable designs for specific applications
Commercial Applications: - Aerospace industry for lightweight components - Automotive sector for foam-based parts - Consumer goods manufacturing for custom foam products
Questions about the Technology: 1. How does the activation of the foaming agent contribute to the formation of the polymeric foam?
- The activation of the foaming agent causes expansion and formation of bubbles within the polymer, resulting in the foam structure.
2. What are the advantages of using a separate heating step for activating the foaming agent?
- A separate heating step allows for better control over the foaming process, resulting in more precise foam formation.
Original Abstract Submitted
methods for additive manufacturing of objects comprising a polymeric foam are disclosed and comprise extruding a mixture of a base polymer and a foaming agent that are provided in the form of at least one feedstock material, the mixture produced by admixing the base polymer and the foaming agent within a polymer processing space of an extruder by an independent mixing rotor, and further comprise sequentially depositing multiple layers of the mixture to form a three-dimensional object. heating of the mixture to cause activation of the foaming agent and formation of the polymeric foam may be done during the extrusion process or afterward by a separate heating step.
