| Yep! And you can get this today, from a machine that costs
| less than a smartphone, and it's clean, it's quiet, it
| doesn't make swarf, or dust, or smoke, and it fits on your
| desk! It turns your CAD models into parts in a matter of
| hours out of material of almost-negligible cost. We are truly
| living in the future.
|
| If you don't _want_ to make low-volume runs of custom parts,
| then 3d printing is utterly useless to you. But it is
| absolutely game-changing for people who do.

| So my advice for anyone reading this is that, if you have kids
