Small companies are producing parts for constructing rockets using 3D printing, a technology that has potential to shake up domestic manufacturing.

New Frontier Aerospace says it has put its 3D-printed Mjölnir rocket engine through a series of successful hot-fire tests.

One just launched the world’s biggest rocket, with mixed success. The other makes small model rockets for hobbyists, and it’s stockpiling supplies ahead of Trump’s tariffs.

The previously used Rutherford engine passed qualification tests and is set to make history as the first 3D-printed engine to reach space for a second time.

These are the best model rockets ahead of Amazon Prime Day, featuring NASA and Blue Origin, as well as STEM rockets, all included.
