We do print the engines using 3d printers.

我们使用3D打印机打印引擎。

So each one of these engines is 3D printed out of Inconel super alloy, and right now, we can print round about one engine every 24 hours.

所以这些引擎中的每一个都是用 Inconel 超级合金 3D 打印的，现在， 我们每 24 小时可以打印大约一个引擎。

So we came up with a new cycle called the electric turbo pump, which we'll talk about in a moment, but we also managed to be able to 3D print these rocket engines.

所以我们想出了一个叫做电动涡轮泵的新循环，我们稍后会谈到， 但我们也设法能够 3D 打印这些火箭发动机。
