Key Technologies in LAAM
Several technologies have been developed to facilitate large-scale additive manufacturing:
- Big Area Additive Manufacturing (BAAM): Developed by Oak Ridge National Laboratory in collaboration with Cincinnati Inc., BAAM uses an extruder on a gantry system to produce large polymer parts.
- Large Scale Additive Manufacturing (LSAM): Created by Thermwood, LSAM combines additive and subtractive processes, featuring a 3D printing gantry and a five-axis CNC router. This hybrid approach enables the production and finishing of parts within the same machine, enhancing efficiency.
- Electron Beam Additive Manufacturing (EBAM): Pioneered by Sciaky, EBAM utilizes an electron beam to melt metal in wire form, allowing for the creation of large metal components.
Applications of LAAM
LAAM has found applications in various sectors due to its ability to produce large and complex structures:
- Construction: Companies are exploring 3D printing for building construction. For example, Walmart expanded an 8,000-square-foot space using 3D printing techniques to assess the feasibility of faster and more cost-effective construction methods.
- Automotive: The automotive industry leverages LAAM for rapid prototyping and the production of large components, reducing development time and costs.
- Aerospace: LAAM is used to produce large aerospace components, including aircraft wings and fuselage panels, providing advantages like reduced structural weight and enhanced design flexibility.
