EBM vs SLM 3D Printing Comparison

Yapay zekadan makale özeti

Technology Basics: EBM uses electron beam to melt metal powder in vacuum
SLM employs fiber laser to create liquid metal pool
Both technologies use powder bed fusion process
Material and Applications: SLM can print wider range of metals including iron, aluminum, nickel
EBM specializes in refractory materials like titanium and cobalt
EBM used in aerospace and medical industries
SLM found in automotive, construction, and jewelry sectors
Technical Differences: SLM offers better layer height resolution and larger build volumes
EBM has slightly rougher surface finish due to larger beam width
Entry-level SLM machines cost over $350,000
Entry-level EBM printers cost $100,000 to $250,000
Alternatives: DMLS offers better resolution than both EBM and SLM
DED uses metal wire feeding for isotropic mechanical properties
SLS can only print in plastic, unlike SLM's metal printing capability
