Australian metal AM company Titomic announced that it has surpassed ASTM International standards with its Titomic Kinetic Fusion process. The announcement follows a breakthrough in a $2.6 million research project which aims to test and establish certification standards for TKF technology.
The two-year research project, co-funded by IMCRC, CSIRO and RMIT, has the ultimate goal of developing new industry standards for parts created using the TKF process—specifically to address fatigue, crack growth and fracture toughness. By creating these standards, the TKF process can be further validated for use in the aerospace industry, which has some of the most stringent industrial standards.
Titomic is understandably excited to announce that its technology performed very well in tests conducted through the research initiative, even surpassing ASTM standards for metal AM. Parts 3D printed using the TKF process using CP Titanium Grade Two powder reportedly achieved an ultimate tensile strength (UTS) of 634Mpa (83.8% higher than the 353Mpa set by ASTM) and an increased elongation of up to 27.7% (38.5% higher than the 20% set by ASTM).
In other words, parts manufactured using the Titomic Kinetic Fusion process exceed ASTM standard requirements and thus can achieve fatigue resistance and strength properties required by the aerospace industry (as well as other industrial applications).
Jeff Lang, Titomic Managing Director, commented on the achievement, saying: “These test results not only provide validation to industry of titanium parts produced using our TKF process, but more importantly the research conducted across multiple Titanium powder supply chains secured by Titomic outlines why we placed so much emphasis on securing feedstock powders with industry leading companies to capture the entire value chain surrounding our technology whilst meeting ASTM International standards.”
Standards are an area of the additive industry which are increasingly coming into focus, as it becomes apparent that the establishment of industry-wide certifications will unlock the true industrialization of AM. Notably, international standards for AM will be a key topic at the upcoming Formnext trade show in Frankfurt.
