Laser Powder Bed Fusion
Manufacturing Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: An additive manufacturing process where a laser selectively melts metal or polymer powder layers to build a part from a CAD model.
Example in context
“The turbine blade was manufactured using laser powder bed fusion to achieve complex internal cooling channels.”
“Türbin kanadı, karmaşık iç soğutma kanalları elde etmek için lazer toz yatağı füzyonu kullanılarak üretildi.”
Where engineers use it
Laser Powder Bed Fusion is widely adopted in aerospace and medical device manufacturing for producing metal components with intricate geometries. Engineers must optimize layer thickness, laser power, and scan strategy to minimize defects like porosity and cracking.
Synonyms: LPBF, SLM
