Rapid Process for Forming Small Area Fill Features - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240042526 titled 'Rapid Process for Forming Small Area Fill Features
Simplified Explanation
The patent application describes a method for manufacturing 3D articles using a beam system to fuse and melt a powder layer. The method includes different operating modes based on the dimensional parameter of the article.
- The method uses a beam system to selectively fuse and melt a powder layer to form each layer of a 3D article.
- Each layer includes at least one fused solid area that defines a dimensional parameter, such as width.
- When the dimensional parameter is above a threshold, the beam system operates in a first mode, fusing contour and hatch areas separately.
- When the dimensional parameter is below the threshold, the beam system operates in a second mode, using a zig-zag pattern with no contour.
- This method reduces the time required to fuse complex layers with many small features.
Potential applications of this technology:
- 3D printing and additive manufacturing
- Prototyping and rapid manufacturing
- Customized production of complex parts
Problems solved by this technology:
- Time-consuming fusion of complex layers with many small features
- Inefficient use of energy and resources in the manufacturing process
Benefits of this technology:
- Reduced manufacturing time for complex 3D articles
- Improved efficiency and cost-effectiveness in additive manufacturing
- Enhanced customization and flexibility in production processes
Original Abstract Submitted
a method for manufacturing includes operating a beam system selectively to fuse and melt a powder layer to form each layer of a 3d article. each layer includes at least one fused solid area that defines a dimensional parameter such as a width. when the dimensional parameter is above a threshold, the beam system is operated with a first operating mode that includes separately fused contour and hatch areas. when the dimensional parameter is below the threshold, the beam system is operated with a second operating mode that includes a zig-zag pattern with no contour. this method of operation can greatly reduce a time required to fuse complex layers having many very small features.
