MultiFab

PROCESS DESCRIPTION

The SMU RCAM has developed an integrated platform for demonstrating/expanding the concept of multi-fabrication (MultiFab) where additive operations based on laser cladding and the micro-plasma powder cladding are combined with high-speed multi-axis machining via integrated software to control the CNC based system. The MultiFab platform can be additionally configured with dimensional scan capability for reverse engineering, as well as for in-process and post-process inspection.  Different engineering materials in the form of powders are used to manufacture components with variable compositions of Ni-alloys, tool steels, Ti-alloys, and metal-ceramic composites.

 

 

 

 Functionally Graded Material (FGM)  part
ADVANTAGES
 
 Multi-Fab Integrated Platform
•Repairing high-value components such as dies or molds minimizing cost and production downtime
•Manufacturing spare parts for legacy equipment “on-demand” from CAD files eliminating expensive inventory stock
•Producing components with Functionally Graded Material (FGM) compositions with properties unattainable by current manufacturing processes
•Create custom orthopedic implants or scaffolds using patient’s  image scans
•Improve surface resistance to heat, abrasion, corrosion, and erosion via laser cladding
•Synthesizing materials to achieve specific mechanical and physical properties
