ADDITIVE MANUFACTURING APPARATUSES INCLUDING ENVIRONMENTAL SYSTEMS AND METHODS OF USING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18250657 titled 'ADDITIVE MANUFACTURING APPARATUSES INCLUDING ENVIRONMENTAL SYSTEMS AND METHODS OF USING THE SAME
Simplified Explanation
The patent application describes an additive manufacturing apparatus that uses a print head and a recoat head to build a three-dimensional object by depositing build and binder materials.
- The apparatus includes a process chamber that surrounds the print head and recoat head, as well as a linear motion stage that connects them.
- A condenser system is connected to the process chamber to receive a gas stream with a high vapor content and provide a gas stream with a lower vapor content back to the process chamber.
- A blower is also connected to the process chamber and the condenser to create a closed loop that circulates the gas stream through the system.
Potential applications of this technology:
- 3D printing of complex objects with multiple materials
- Rapid prototyping and manufacturing of customized products
- Creation of intricate and precise structures in various industries such as aerospace, automotive, and healthcare
Problems solved by this technology:
- Controlling the vapor content in the process chamber to optimize the printing process and improve the quality of the printed objects
- Preventing excessive vapor buildup that can lead to defects or inconsistencies in the printed objects
- Ensuring a consistent and controlled environment within the process chamber for reliable and repeatable printing results
Benefits of this technology:
- Improved printing quality and accuracy
- Faster printing speeds and increased productivity
- Enhanced control over the printing process and material properties
- Reduced waste and material consumption
Original Abstract Submitted
According to various embodiments, an additive manufacturing apparatus comprises a process chamber surrounding a print head, a recoat head, and a linear motion stage to which the print head and the recoat head are coupled. The print head and recoat head operate within the process chamber to build a three-dimensional object by depositing a build material and a binder material. The additive manufacturing apparatus further comprises a condenser system fluidly coupled to the process chamber to receive a gas stream with a first vapor content from the process chamber and provide the gas stream with a second vapor content to the process chamber. The second vapor content is less than the first vapor content. Additionally, the additive manufacturing apparatus comprises a blower fluidly coupled to the process chamber and the condenser to flow the gas stream through a closed loop comprising the blower, the process chamber, and the condenser.
