Electron beam melting

Electron Beam Melting

Garrick White


How it works

How it works

  • Fuses metal powder together layer by layer - additive

  • Able to also make cuts by vaporizing metal in an area- subtractive

  • Reads from a 3D Cad file


Electron beam melting

Pros

  • Extremely accurate cuts

  • Requires no additional work after the alloy is fused together

  • Parts are created fully solid and very strong

  • Vacuum removes

    impurities in the metal


Electron beam melting

Cons

  • Size of part is limited to vacuum chamber

  • Produces gamma rays

  • Part must be electrically conductive


Application

Application

  • Hip or knee implants

  • Bone plates

  • Aerospace

  • Possibly on moon missions
