Direct Laser Deposition (DLD) method is relatively new technology which has significantly matured in last few years. Although this technique has been well know from the mid 80s, process control is still under investigation. The major application of DLD is in the repair or modification of existing parts or the manufacture of completely new 2-D or 3-D parts. This technology is also commonly used for the addition of special surface layer qualities on a base mate...$28.00
