3D-Printed Rocket Parts Excel in NASA Tests

A continuation of the 3D printed rocket engine injector story a few weeks ago. It has now out performed the milled traditional manufactured injector. The traditionally constructed injectors used in the SLS tests cost about $10,000 each and took six months to build; the 3D-printed versions cost less than $5,000 and only took 40 hours…

Forget 3D printing—3D subtraction is going to arrive in your garage first

CNC routing is basically the inverse of 3D printing. Instead of using a computer to control a basic armature and print head that deposits plastic or some other material in three dimensions, CNC routing uses a spinning drill bit to carve wood, metal or plastic. It’s the difference between making a sculpture out of clay and…

NASA, Industry Test Additively Manufactured Rocket Engine Injector

NASA cuts manufacturing time from 1 year to 4 months and cuts costs by 70%. NASA and Aerojet Rocketdyne designed and fabricated a key part for a rocket engine with a 3D printer, shaving six months and 70 percent off the cost of production. A successful test of the component, a rocket injector assembly that delivers liquid…
