"You could build wireframe 3-d objects, where each strut was just one of those thin strips, but what we've done is create multi-layer bricks" - and then stack them.
而我们目前所完成的则是创造多层砖块，然后再把他们堆积起来。

But just like any other skyscraper, these 3-d chips have to keep the power flowing from layer to layer without overheating.
但正如其他摩天大楼一样，3 - D芯片需要保证各层之间的能量保证，但又需避免发热量过大。

The first step in all 3-d printing processes is for software to take cross-sections through the part to be created and calculate how each layer needs to be constructed.
