What do rockets, ski boots and submarines have in common? They can all be assembled with plastic-printed components.
Brackets, nozzles and other parts used in the Atlas V rocket were recently 3D printed in polyetherimide. The ski boot was created with a polyamide-based material reinforced with carbon fibers. Blades, fins, steering components and other parts of the miniature sub were printed with acrylonitrile-butadiene-styrene (ABS).
