Summary
Selective electron beam melting (SEBM) was improved by modifying the sintering process. This modification enhances productivity by approximately 20% while maintaining comparable mechanical properties for titanium components.
Area of Science:
- Additive Manufacturing
- Materials Science
- Mechanical Engineering
Background:
- Selective electron beam melting (SEBM) is an additive manufacturing technique for metals.
- Current SEBM sintering processes present post-processing challenges and reduce productivity.
- Improving SEBM sintering is crucial for enhanced geometric accuracy and resolution.
Purpose of the Study:
- To modify the sintering process in SEBM for improved productivity and easier post-processing.
- To investigate the impact of scan speed on highly porous titanium test specimens.
- To achieve comparable or improved mechanical properties with reduced build times.
Main Methods:
- Modification of the sintering process in SEBM.
- Building highly porous titanium test specimens at various scan speeds.
- Conducting tensile tests to evaluate mechanical properties.
Main Results:
- An average productivity improvement of approximately 20% was achieved by sintering only the area of the melt pool.
- Mechanical properties from tensile tests were comparable or slightly improved compared to reference components.
- The modified process facilitates easier removal of residual powder post-build.
Conclusions:
- Modifying the SEBM sintering process can significantly enhance productivity.
- The study demonstrates that reduced build times are achievable without compromising mechanical integrity.
- Optimized sintering strategies offer a pathway to more efficient additive manufacturing of titanium components.
