Method for Producing an Object Layer by Layer - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240009771 titled 'Method for Producing an Object Layer by Layer
Simplified Explanation
The abstract describes various embodiments of a method for producing objects using a powder-based 3D printing process. The method involves selectively fusing layers of powder in a powder bed using a selective laser melting or selective electron beam melting process. The layers are fused in groups, with at least two successive layers being part of a group.
The method includes the following steps for each group: - Providing a first layer of powder - Fusing a part of the first layer using first exposure vectors that are parallel to each other and at a defined spacing - Providing a second layer of powder - Fusing a part of the second layer using second exposure vectors that are arranged at an offset parallel to the first exposure vectors - The exposure vectors of successive groups are rotated by an angle relative to each other.
Potential applications of this technology:
- Manufacturing complex and customized objects with intricate geometries
- Rapid prototyping and product development
- Production of parts for industries such as aerospace, automotive, and medical
Problems solved by this technology:
- Overcoming limitations of traditional manufacturing methods in producing complex shapes and structures
- Reducing material waste compared to subtractive manufacturing processes
- Enabling the production of objects with high precision and accuracy
Benefits of this technology:
- Increased design freedom and flexibility in creating complex objects
- Faster production times compared to traditional manufacturing methods
- Cost-effective production of small batch or customized objects
- Reduced material waste and environmental impact compared to traditional manufacturing processes
Original Abstract Submitted
various embodiments of the teachings herein include methods for producing an object layer-by-layer using a powder-based 3d printing method by selective fusing of layers of a powder in a powder bed with a selective laser melting process or selective electron beam melting process. at least two successive layers are part of a group. an example method includes, for each group: providing a first layer of the powder; fusing a part of the first layer with first exposure vectors parallel to one another and at a defined spacing; providing a second layer of powder; and fusing a part of the second layer with second exposure vectors arranged at an offset parallel to the first exposure vectors. the exposure vectors of successive groups are rotated by an angle relative to one another.
