Aluminum SLM Heat Sink for Power Electronics

When conventional machining could not produce the lattice structure required for a compact heat sink, an energy systems team turned to SLM aluminum on AIHFABS to compare metal printing partners.

Challenge

• Complex internal lattice for thermal performance
• AlSi10Mg material specification required
• Need machined datum surfaces after printing

Solution

AIHFABS matched the project with SLM suppliers experienced in aluminum power electronics parts. The quote included notes on build orientation, support removal, and CNC finishing add-ons.

Results

• Functional metal samples delivered for thermal bench testing
• Design team validated airflow assumptions before mass-production tooling
• Single platform workflow reduced supplier coordination overhead
