Functional Testing of Direct Metal Laser Sintered (DMLS) Components for Automotive Application
This work presents the results of a study to determine the wear behavior of components manufactured by direct metal laser sintering (DMLS). Wear is an important issue in using layer manufactured parts for functional application. Two different bushes were selected for the functional testing for wear behavior studies. Specimens (bushes) were manufactured by DMLS technology and was tested for wear behavior and compared with bushes manufactured by conventional manufacturing methods. Components were manufactured by using the process parameters like sintering speed, hatch spacing, post contouring speed, hatch type and infiltration with an optimized value. Testing was carried out for bushes, used for an automobile engine starter motor. A comparative study for the wear behavior was carried out and results are discussed.
