Higher Productivity Laser Powder Bed Deposition

There have been significant developments in the field of additive manufacture in recent years, and TWI has taken a strong lead in the area of Laser Metal Deposition (LMD) using blown powder and Selective Laser Melting (SLM) using powder bed systems.

 This presentation cover the developments made in recent research work on making the process as productive as possible, including the following areas of work:

• Testing the SLM process powers greater than 200W, with a view to substantially increasing the productivity of the process.
• Generating procedures around a skin and core approach.
• Surface finish improvements made using SLM.
• Selection of case studies for both the LMD and SLM process for the aerospace industry.
