The typical lead time to traditionally forge the part is one year, according to Andy Pfeiffer, an engineering design lead and additive manufacturing expert for Boeing Global Services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Boeing plans to print parts associated with the main rotor system and conduct full-scale fatigue testing against traditionally forged parts in April 2024, Pfieffer said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But there are thousands of parts that are capable of being 3D-printed rather than made through castings and forgings that now require replacing, said Scott Rose, a welding engineer for Boeing\u2019s research and technology unit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Apache program has so far provided a list of eight parts designated as items that require replacing as soon as possible and were deemed good candidates for 3D printing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to helping with engineering efforts, ASTRO is also gathering and retaining data that would help determine the business case for making various parts and components, Gallegos said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In some areas, it might make sense to continue to make parts through forging because they are made in large numbers, Rose explained. But if the quantities are low, additive manufacturing might be the way to go, Rose added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For some parts, Rose said, the microstructure of the material is stronger when 3D-printed than it would be through the traditional manufacturing process \u2014 and might last longer. Other considerations include the current supply base of some parts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf you already have the tooling and you\u2019ve got a supplier willing to make it with the tooling, a lot of times the business case isn\u2019t going to be there,\u201d he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But if there\u2019s an aircraft on the ground, repairing that aircraft quickly with a 3D-printed part rather than waiting on a traditionally forged part to avoid keeping it out of commission would factor into the business case as well, according to Pfeiffer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe\u2019re excited to get parts qualified, especially large critical parts,\u201d Pfeiffer said. \u201cThat unlocks a lot more.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Boeing has teamed up with ASTRO America to 3D-print parts for its Apache attack helicopter as a way to potentially improve supply
