Titomic has shown off the world’s largest additive manufactured titanium part at the Formnext 3D printing trade show in Frankfurt.
The 5.5m-high rocket was created using the TKF 9000, the world’s largest and fastest metal additive manufacturing system at Titomic’s Melbourne production bureau.
The rocket was manufactured using Titomic Kinetic Fusion (TKF) in just 27.6 hours. It is a scale version of the 27m-long Gilmour Space ERIS-S rocket that has been designed to provide reliable and cost-effective access to space.
Titomic reckons it could build the full-scale space rocket in 165 hours using its patented TKF additive manufacturing process and using economical high-performance titanium and other super alloys.
While titanium is highly desirable in aerospace applications, it is in limited supply and expensive. As a result, many high-profile aerospace organisations, such as SpaceX, are forced to use stainless steel 301, a material that is twice the weight and a quarter the strength of titanium.
Titanium provides superior mechanical properties of higher fatigue and tensile strength, lower thermal expansion and specific heat capacity compared with stainless steel.
Titanium rockets made with TKF are half the weight of stainless-steel rockets made with traditional manufacturing methods, which allows increased payload mass and volume capability, opening new possibilities for economic payload delivery to space.
TKF allows very large, seamless shapes to be produced, showcasing advances in additive manufacturing that not only show improvements in productivity and affordability, but surpass traditional manufacturing methods.
According to Titomic MD Jeff Lang: “Previously, titanium was more than twice the price of stainless steel but with the development of new supply chain of titanium powder and Australia’s significant mineral sand resources of about 280Mt of titanium, Titomic is at the forefront of advancing technology for future sustainability of the Earth’s resources and reducing carbon emissions for global manufacturing.’’
