CAD directly to METAL with Free-Form-Fabrication

• Direct Manufacturing
• Fully-Functional Prototyping
• Complex Geometries
• Costs comparable to castings
• Material performance comparable to CNC billet
• Speeds as high as 1.6" per hour
• Build envelope of 8" x 8" x 7"

• Electrons are emitted from a filament, which is heated to over 2500 C
• The electrons are accelerated through the anode to half the speed of light
• A magnetic field lens brings the beam into focus
• Another magnetic field controls the deflection of beam
• When the electrons hit the powder, kinetic energy is transformed to heat

• Good vacuum at less than 10-4 mbar
• Very small melt volume
• Rapid cooling from liquid to solid state
• Continuous stirring in the meltpool

The material from the EBM process:

• Naturally aged condition
• Fully melted
• Vacuum melt quality eliminates impurities
• Microstructure similar or better than cast
• Controlled grain size
• Monitored thermal environment
  • Good form stability
  • Low residual stress in part
  • Consistency
• High yield strength properties
• 100% Density
