The hot-forming process creates complex shapes without fracturing, spring-back or residual stress.

Titanium has the highest strength-to-weight ratio of any metal. It’s as strong as some steels, but 45 percent lighter. Titanium is also prized for its corrosion resistance, fatigue resistance, crack resistance, and ability to withstand moderately high temperatures without creeping.

MELBOURNE, Australia—Engineers at the Royal Melbourne Institute of Technology have developed a way to print titanium-copper alloys. The lightweight material is ideal for many types of aerospace and medical device applications.
