Laser Metal Deposition Machine - Trumpf TruLaser Cell 7040+

TWI’s UK-leading laser cladding research and development facility utilises a unique the Trumpf 7040 LMD system.

The specially-commissioned laser metal deposition (LMD) machine is very unique as it is the only one of its kind in the world. The machine uses a 50 micron nozzle positioning accuracy across its entire 4m x 2m x1.5m work envelope. 

It's also equipped with 7 axis, a Renishaw touch probe, a dual core LLK and disc laser giving automatic spot size adjustment from 0.7 to 7mm, and offering unparalleled nozzle precision and accuracy and part referencing / scanning.

The system assists with TWI’s ability for large-scale repair and additive manufacture / 3D printing of parts for industry, including within the aerospace sector.

Features and Benefits

  • Equipped with TWI developed ToolCLAD™ CAM software for 2D and 3D tool paths
  • 5 axis nozzle positioning and 2 axis tilt-turn table fully integrated with TCP transformations
  • Two controllable powder feeders for material delivery
  • In-process control of laser power and spot size
  • On-board Renishaw Touch Probe for substrate referencing and part geometry analysis 
  • In-process monitoring and measurement of laser power and powder deposited rate
  • Large build envelope
