    Yapay zekadan makale özeti

    General Overview
    • 3D printing creates objects layer by layer using various materials
    • Both DMLS and SLM use laser energy to fuse metal powder
    • Both technologies can produce complex metal parts with various materials
    DMLS Technology
    • Uses high-energy laser to melt metal powder directly
    • Offers coaxial and roller powder feeding methods
    • Prone to spheroidization and thermal deformation
    • Can use multi-component powders with different melting points
    SLM Technology
    • Completely melts metal powder under high laser energy
    • Requires laser energy density exceeding 106W/Cm2
    • Uses single metal powder for printing
    • Produces parts closer to full density
    • Creates smoother surface finish
    Comparison
    • SLM melts all powder, DMLS partially melts some
    • DMLS offers better material flexibility
    • SLM has better mechanical properties
    • SLM has single powder feeding method, DMLS has two
    • SLM parts have smoother surface finish
