AM in Turbomachinery: Deep dive in Applications, Materials, Production and Qualification

Sustainable Plastics 1 – Use and Reuse of Powder - BLUEPRINT

$AM Rocket Engines and Space Nuclear Power with Omar Mireles Fabian Alefeld interviews Omar Mireles, Director of Manufacture and Materials at Space Nuclear Power Corporation (Space Nukes), about his career spanning NASA, Oak Ridge, and Los Alamos and how additive manufacturing (AM) reshaped space hardware development. Omar describes early exposure to SLS prototyping, graduate work in nuclear materials and propulsion, building nuclear materials labs at NASA Marshall, and later leading AM efforts for liquid rocket engines and refractory metals. He explains how AM accelerates iteration, enables complex geometries, part consolidation, and weight reduction, and where traditional methods still dominate depending on production rate. The conversation covers refractory metal challenges (supply chain, oxygen sensitivity, post-processing, inspection) and nuclear reactor basics, generations, and regulatory barriers to AM adoption. Omar outlines Space Nukes’ goal of delivering safe, affordable, reliable power anywhere in the solar system, noting heat rejection as a key space constraint, Krusty’s 2018 test heritage, potential AM roles in heat exchangers, and an aggressive ~2-year flight timeline depending on regulation and mission. 02:26 Omar Early Motivation 03:08 NASA Co-ops and First AM 07:59 Stirling Radiation Research 20:07 Refractory Metals AM Lab 21:31 Los Alamos to Space Nukes 25:14 Did AM Change Space Race 31:46 Where AM Flies Today 37:41 Rocket Engines Print vs Traditional 41:15 Refractory Alloys Challenges 46:39 Where Refractories Make Sense 47:05 Will Refractory AM Grow 49:39 NASA Metal AM Handbook Origins 56:37 How Nuclear Reactors Work 01:13:02 Additive Manufacturing in Nuclear 01:18:31 What Space Nukes Builds 01:19:36 Why Space Nuclear Power Matters 01:25:20 Why Space Needs Nukes 01:37:47 Krusty Test Proof 01:41:18 Heat Rejection Challenge 01:49:25 Timeline and First Missions Subscribe to our YouTube channel: YouTube: https://www.youtube.com/eosgmbh?sub_c...
