RAM3D digitally print titanium safety knives for Team NZ
As a leader in metal 3D printing RAM3D was chosen to design and manufacture light-weight yet tough titanium safety knives for America’s Cup sailors Team NZ.
John Bamford, of Victory Knives and RAM3D set about designing a state-of-the-art knife that needed to be light weight but strong enough to cut through marine ropes. The knife and sheath were 3D printed in Ti64 alloy powder, then super coated, to produce a knife that can cut super strong marine ropes in one blade stroke compared to their existing knife which took 10 strokes.
With all hands to the tiller, a trial knife was designed and printed within a week. A sheath that could be sewn on to the sailors’ wetsuits followed soon after.
After only one trial and a few changes, 55 knives were manufactured, boxed and sent to Team NZ three days early. The sailors tested the knife’s strength by throwing it off a building on to asphalt from approximately 14m and they did that about 20 times, and then they threw it against a brick wall about 10 times and then they ran it over with a forklift 10 times. That was their acceptance testing and it survived, it didn’t get broken.
