Continuing on from day 1 of the #inktober #engineering challenge, we refine the performance requirements of our metal additive manufacturing system in terms of:

  1. The business benefit that it provides to the end user – our customer’s customer
  2. The output of the system – the product it produces, not the product (the system) we are designing

We also preview two “fun” precision engineering challenges that we’ll have to deal with:

  1. Thermal management issues at precision interfaces
  2. Interchangeability

Our machine is a little unique in that the product it produces has three states and associated processes:

  1. Raw powder material distributed evenly
  2. The pattern being built up and fused together from that powder
  3. The finished product, which is then transported on a pallet for secondary operations

We begin to identify the considerations in each state and at each stage of the project that affect performance as we have defined it.
