       | Of course, not on this level but, a few weeks ago I was invited
       | to see an astonishing 3D confection printer in action. It was
       | printing a fantasy-looking cityscape to top a custom cake. I
       | couldn't really talk to anyone about the technology as the
       | operator was behind a glass partition but it looked as though it
       | was full color using, I'll guess, some sort of spun sugar
       | filament system.
       | 
       | The geometric resolution was incredible, and it was very fast
       | (and looked very expensive).

       | judge the result.

       | future to make tasty things that are actually healthy for you,
       | for example by controlling the surface area of certain flavors
       | and suppressing others while providing all the essential amino
       | acids and nutrients.

       | I'd wanted a laser on a 3D printer years ago, to heat a spot on
       | the layer below just ahead of laying new filament. 3D filament
       | printing is, after all, welding a hot thing to a cold thing,
       | which never works well. Not much laser power, just 1-2 watts.
       | Might be able to fix the "weaker in the layering direction"
       | problem.
