Installation Qualification for LPBF Scanner Subsystems
Laser-based powder bed fusion of metals (PBF-LB/M) relies on precise scanner subsystem performance to ensure dimensional accuracy, surface finish quality, and build repeatability.
Current installation qualification (IQ) standards for scanners often have drawbacks:
- Costly and time-consuming procedures
-Complex test setups requiring specialized equipment
- Limited ability to assess multiple performance aspects in a single evaluation
These challenges can delay production readiness and make it harder to ensure consistent part quality across machines.
The Solution
This research introduces a novel, user-friendly installation qualification (IQ) method for LPBF scanner subsystems that uses a simple plate melt test.
The method enables evaluation of multiple key performance metrics in one test, including:
- Laser and scanner delays
- Acceleration performance
- Dimensional accuracy
- Slicer software interpretation
By consolidating these measurements into a single build, the method streamlines IQ, reduces downtime, and removes the need for expensive, complex setups.
Key Benefits
Faster Qualification
– Complete scanner IQ in significantly less time compared to current methods.
Comprehensive Assessment
– Measures multiple scanner performance aspects in a single run.
Easy Adoption
– Practical for both OEM qualification and in-house machine verification.
Cost-Effective
– Eliminates the need for costly external fixtures or specialized equipment.
