Why FIT?

  • As an early adopter of WAAM, we are intimately familiar with the technology and can manufacture components with complete reliability.
  • Our extensive selection of materials, the outstanding quality of the components, and the rapid build-up rates open up a whole range of applications for manufacturing individual parts, small series, or 3D printed spare parts.
  • WAAM allows us to quickly print numerous individual structures on a base body when low quantities and a high component variance are required.

WAAM - description of the process

Wire arc additive manufacturing (WAAM) uses arc welding to build up the component in layers. A metal wire is melted at the right place using a welding torch to form the desired blank. The rotating building platform means that the material build-up takes place across 5 axes with a maximum component size of 1 m³. This allows complex structures or cavities to be manufactured. The built-up component is then finally machined by CNC milling.

Benefits

  • Material savings with targeted material application
  • Up to 60 % cheaper than subtractive CNC manufacturing
  • High build-up rate of up to 600 cm³/h, making it much faster than powder bed-based technologies
  • High variety of materials
  • Minimum distortion and low residual stress in the component
  • Pore-free layer structure
  • Hybrid construction, i.e. welding onto semi-finished products
