3d printing got oversold. &quot;Print replacement parts for your washing machine&quot; was total bullshit. 3D printer CEOs wanted to be like Steve Jobs and sell millions of devices to consumers. They could have earned a respected spot in the toolboxes of engineers, artists, scientists, even manufacturers. Instead they pushed trinket machines that didn&#x27;t even work as designed. They could have been like Tektronix or Mori Seiki but they got greedy.
