2. Aerospace: Barriers to AM Adoption
• Tier 1 manufacturers cannot afford to risk the use of subcontractors for
the production of mission/safety critical parts. Verification and validation
standards set by the government or OEMs are appropriately strict on
such applications.
• The current state of development of AM has inherent machine-to-machine
variance, material batch variations and in-house processing know how. As
a result, the Tier 1 manufacturers make their own parts or limit
subcontracting only to key trusted suppliers. Thus, there are currently
very few opportunities for a service bureau or Tier 2 manufacturer to
enter the AM aerospace supply chain.
• Post-processing costs are often as high as the build cost.
• One regional aerospace supplier invested in a DMLS machine, but has
been unable to penetrate aerospace applications due to the above supply
chain constraints.
