On November 10, Blue Origin unveiled its next-generation Northstar rocket engine, in which more than 65% of components are additively manufactured, making it the model with the highest printed-part ratio in the company's engine family. The deep application of additive manufacturing in liquid oxygen-methane engines further establishes metal 3D printing as a standard feature of commercial space propulsion systems. Value for buyers: a higher printed-part ratio means growing demand for superalloy and copper alloy powders and for printing services, and compliant suppliers can track the company's supply chain tender activity.
