ASC, in cooperation with CSIRO and DMTC Limited, has used 3D printing technologies to carry out the maintenance and repair required for its submarine fleet.

 It is known that the numbers of naval military parts of any country may be completely deceptive, because only a few fleet pieces are available for use most of the time.

For example, only one in four submarines could be in active service, while the remaining submarines are in transit, under repair, and periodic maintenance, or are intended for use in the field of training.

ASC therefore worked to maintain the full strength of the Royal Australian Submarine fleet into a plan to accelerate repairs and maintenance using 3D printing technology, as part of a project to be implemented within two years.

The foundation, in particular, is developing a cold spray technology, which releases a supersonic gas mist to help form metal powder particles quickly to form dense deposits on surfaces.
