Invention Reference Number
This technology addresses the challenge of distortion and warping in additive manufacturing (AM) processes by incorporating custom geometries into the baseplate that counteract bending moments. By increasing compliance in the baseplate, it reduces residual stresses and warpage, resulting in flatter, higher-quality parts that are easier to post-process. This innovation is particularly beneficial in hybrid manufacturing setups that combine additive and subtractive methods.
Description
Distortion is a common problem in additive manufacturing, caused by the residual stresses generated during the deposition and cooling process. These stresses can result in significant bending of the baseplate, making parts unusable or difficult to machine post-deposition. The proposed solution involves designing compliant mechanisms into the baseplate that allow the material to contract naturally, reducing the bending moment and overall distortion. This approach not only improves part quality but also enhances the safety and efficiency of the manufacturing process by reducing the risk of equipment failure and improving part handling.
Benefits
- Reduced warpage and distortion: Allows for flatter baseplates and more consistent parts, improving usability and post-process machining.
- Easier handling and machining: Flatter baseplates make it easier to fixture parts, reducing setup time and machining complexity.
- Faster lead times: Reduces time required for post-processing, leading to quicker part availability.
- Cost savings: Minimizes material waste, machining complexity, and overall production costs.
- Particularly suited for industries that use both AM and machining for part creation.
