IN-SITU REACTIVE CURING AND INFILTRATION IN BINDER JET ADDITIVE MANUFACTURING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240239042 titled 'IN-SITU REACTIVE CURING AND INFILTRATION IN BINDER JET ADDITIVE MANUFACTURING
The abstract of the patent application describes a method of binder jet additive manufacturing (BJAM) that involves feeding powder particles to a powder bed, delivering an organic binder onto the powder bed in select locations to form a porous green part, and introducing a secondary component that chemically reacts with the binder to form a solid polymer matrix around the powder particles. The secondary component can be introduced by infiltrating it into the green part or by combining it with the powder particles before feeding them to the powder bed.
- Feeding powder particles to a powder bed
- Delivering an organic binder onto the powder bed in select locations
- Introducing a secondary component that chemically reacts with the binder to form a solid polymer matrix
- Secondary component can be introduced by infiltration or by combining it with the powder particles
- Binder system includes an organic binder and a reactive secondary component
Potential Applications: - Manufacturing of complex geometries - Production of customized parts - Prototyping in various industries
Problems Solved: - Simplifies the manufacturing process - Enables the creation of intricate structures - Enhances design flexibility
Benefits: - Increased efficiency in manufacturing - Reduction in material waste - Improved product quality
Commercial Applications: Title: Advanced Binder Jet Additive Manufacturing Technology for Industrial Production This technology can be used in industries such as aerospace, automotive, and medical for rapid prototyping, customized part production, and small batch manufacturing.
Questions about Binder Jet Additive Manufacturing: 1. How does the introduction of a secondary component improve the properties of the final part? - The secondary component chemically reacts with the binder to form a solid polymer matrix, enhancing the strength and durability of the part. 2. What are the advantages of using a binder system with a reactive pair in BJAM? - The reactive pair allows for the formation of a solid polymer matrix, improving the overall quality of the manufactured parts.
Original Abstract Submitted
a method of binder jet additive manufacturing (bjam) is provided. the method includes feeding a supply of powder particles to a powder bed, delivering an organic binder onto the powder bed in select locations of each layer to form a porous green part, and introducing to the binder a secondary component that chemically reacts with the binder to form a solid polymer matrix around the powder particles. the secondary component is introduced either by: (i) infiltration of the secondary component into the porous green part; or (ii) by combining the secondary component with the powder particles prior to feeding the powder particles to the powder bed. a binder system for bjam is also provided. the binder system includes a reactive pair including an organic binder that is capable of being deposited on a powder bed; and a secondary component that is reactive with the organic binder.
