BAE Systems and 3D printing company
Renishaw have formed a Memorandum
of Understanding (MoU) to improve addi-
tive manufacturing (AM) for the defense
and aerospace sector.
The companies say that they want to
improve the performance, reduce the costs
and speed up the manufacturing processes
of combat aircraft in future. The agree-
ment also opens up opportunities for joint
research and development, BAE said.
The company already reportedly owns
several Renishaw 3D printers at its 1000
m2 new product development and process
development center (NPPDC).
BAE is already using AM technology to
make production standard components
for the Typhoon fighter aircraft and in
the rapid prototyping of new technology
concepts for the Tempest combat air
system.
‘Additive manufacturing has and will
continue to deliver significant benefits to
our sector,’ said Andy Schofield, technol-
ogy director for BAE Systems. ‘In an envi- BAE Systems;
