A couple of weeks ago, we showed you a type of hoverboard apparently powered by a jet turbine engine.

几周以前，我们给大家介绍了一种由喷射涡轮引擎提供动力的悬浮滑板。

It's the same tech that's used to print stuff like auto parts and jet turbines.

它与用于打印汽车零部件和喷气涡轮机等产品的技术相同。

But instead of being powered by jet turbines they rely on sets of electrically driven rotors, much like hovering drones.

但它们不是由喷气涡轮机提供动力，而是依靠成套的电动转子，就像悬停的无人机一样。
