Q1) The redesigned brake caliper is manufactured using SLM from Titanium Ti6Al-4V alloy powder. How many SLM machines are required to manufacture parts for 450 vehicles which are to be built in a 20-month production period. The following parameters are in effect:

  •  5 parts can be built at once on a single machine
  • The caliper has a height of 173mm.
  • Each layer is 64 µm thick
  • 4 scanning lasers are used which share the scanning time for each layer
  • The average laser scanning time for each layer with a single laser is 63 seconds
  • The powder recoating time for every odd numbered layer is 18.6secondsand 38.75 seconds for every even numbered layer
  • Every 8th layer is scanned twice, at 2.3 times the usual laser scan speed to provide additional heat input for in-situ heat treatment
  • The SLM machine operates at a duty rate of 42% of the 24-hour day, Monday to Friday, for 48 weeks of the year, with 10% of production time lost to unscheduled downtime.
