The Metal Additive Manufacturing Technology Centre (MAMTeC)
at the Royal Netherlands Aerospace Centre (NLR) in Marknesse, the Netherlands,
has launched a new Additive Manufacturing technology programme designed
to help its participants introduce certified metal AM parts.
The NRL will work with a consortium of partners on the
certification of critical metal AM components for aerospace, oil & gas,
high-tech/high-spec industry, defence, and automotive applications. The
programme is scheduled to run for four years, and is a follow-up of an early
successful metal AM programme run by NLR from 2015–2018.
As part of the new programme, the MAMTeC will install a BeAM
Modulo 400 Directed Energy Deposition (DED) machine dedicated to part
manufacture and repair. The NRL explained that to fulfil stringent
certification requirements, a qualified and stable manufacturing process is
required. Therefore, research into the application of in-situ process
monitoring systems will also be an important part of the programme.
Another important aspect of the programme will be related to
process simulation for both Laser Powder Bed Fusion (L-PBF) and DED in order to
gain insight into the temperature profile during processing. Using process
simulation, the residual stresses in AM products can be predicted and an
optimal AM production approach can be designed.
Various materials will also be investigated and test
programmes will be executed to define the material properties of
high-performance materials such as titanium and nickel-based superalloys.
Participants of the new Public Private Partnership project
include Oerlikon, Shell, Patria, BeAM, The Dutch Ministry of Defence, Thales,
Aeronamic, KIMS (Korea) and Mokveld Valves.
