BELOW: TRUMPF's TruPrint 5000 is a highly productive, semi-automatic Laser Metal Fusion (LMF) machine for high industrial 3D printing requirements. investigating conventional aerospace alloys such as IN 718, TI 6-4, or 17-4 PH, special attention is required. Just perfecting these conventional materials requires a substantial empirical effort. In many cases, this can take years and cost hundreds of thousands of dollars to properly characterize. A breakdown of the estimated use of powder for aerospace is provided in the following chart. It is believed that powder AM parts represent at least 75% of the total number of parts used in aerospace. 34 January 2022 UPDATE TRUMPF Aerolytics 30 M 2 6 45 7 10
