Evaluation of laser metal deposition using stellite® 21 for die remanufacturing

Project aim

Validate and appraised laser metal deposition with powder (LMD-p) as a remanufacturing method of high-value tools, moulds and dies.

Project background

The exploitation of additive manufacturing (AM) in the repair and remanufacture of industrial components, such as moulds and dies, has become an emerging research area due to the expected reduction of replacement cost and the promise of better mechanical and wear resistance properties. Moreover, the use of remanufacturing standards ensures a greater than or equal to warranty part quality.

Laser metal deposition with powder (LMD-p) has been used to remanufacture artificially worn H13 Steel samples, allowing for benchmarking studies to be conducted in order to compare the mechanical and wear resistance performance of LMD-p against current welding repair technologies.
