研究目的
Investigating the integration of a light emitting diode (LED) into an additive manufactured metal component using selective laser melting (SLM) and laser metal deposition (LMD).
研究成果
The study successfully demonstrates the integration of an LED into a metal part using a combination of SLM and LMD. It highlights the importance of parameter selection to prevent the destruction of electronic components during the manufacturing process. Future research should focus on more complex parts with sensor integration for industrial applications.
研究不足
The high process temperatures during LMD can destroy the electronic components if not properly managed. The study is limited to the integration of a simple LED and does not explore more complex electronic integrations.
1：Experimental Design and Method Selection:
The study uses SLM for manufacturing the base component and LMD for embedding the LED. Two strategies with different parameter combinations are tested for filling the groove with LMD.
2：Sample Selection and Data Sources:
The base part is made of chrome-nickel steel 316L, manufactured by SLM, with a solid body and a grid structure area.
3：List of Experimental Equipment and Materials:
A TRUMPF TruDisk
4：0 kW Yb:
YAG laser and a coaxial annular gap nozzle are used for LMD. The filler material is 316L with a grain size of 45 μm to 90 μm.
5：Experimental Procedures and Operational Workflow:
The LED is embedded in the grid structure, and the groove is filled with LMD using two different strategies with varying parameter sets.
6：Data Analysis Methods:
The study compares the number of tracks and welding time between the two strategies to evaluate their effectiveness.
