spentmiles: When I was in elementary school, the teacher gave us a writing prompt: What would you do if you could be invisible for a day?

At the time, my elderly grandfather was living with us.  He had a small fortune but after my grandmother died, he said he was lonely and wanted to live with us.  I overheard my mom and dad fighting about it.  The gist that I got was that grandfather was wealthy and we'd get more money after he died if he lived with us.  He was nice to me, giving me drinks of his beer, cigarettes, and money whenever I asked.  Him and my dad didn't get along whatsoever, though, so dad started traveling more with work after he moved in with us.

As dad traveled more, I started hearing really weird noises coming from grandpa's room at night.  The first time, I got scared and ran to my mom's room, but she wasn't in her bed.  I couldn't find her anywhere in the house, so I just hid under the covers.  I fell asleep and in the morning mom was downstairs cooking breakfast.  I asked her about the noises, but she said she hadn't heard anything.  When I asked where she was, she got mad and told me to stay in my room at night.

The noises continued to get worse.  There was laughter and moaning and sometimes screaming, like people were fighting in their sleep.  I was peeking out of my door one night when I saw mom leave grandpa's bedroom.  She was completely naked.  I came out and asked her what was going on.  She said that she was sleepwalking and I shouldn't tell anyone because she was so embarrassed.  I told her that we'd keep it our secret.

I was still curious as to what was going on in there.  So, I wrote my assignment about being invisible and sneaking into my grandfather's room while my mom was in there with him at night.  After the teacher read it, she called my dad.  My parents got divorced after that and my dad ended up moving to Florida.  My grandfather stayed with me and my mom, which was fun, though we had to move into a smaller apartment and they had to sha ...

So, they can make something that is invisible to microwaves (like that really comes up) and they can make a gun that explodes on the second or third shot. 3D printers: what CAN'T they do?

It's spentmiles.  It's a bogus but humorous story that is long, drawn out, and with a dry punch-line.

I think the invisibility cloak for visible light is easily achieved with a sheet of plywood.

See, can't see me!

It works in infrared, too.

In before someone hypes 3D printers as the replacement for large manufacturing.

/economies of scale
//very few things are made of powder and glue.

It'll never replace centralized manufacturing of most goods.  What it *WILL* do is enable people to manufacture one-off goods themselves in response to a pressing need or want, with little or no actual shop skills necessary, and with very minimal equipment compared to a traditional manufacturing.

Take the example of guns.

My father builds guns.  In fact, he build my flintlock.  He has a wealth of metal and wood-working skill and knowledge that I don't possess, along with tools like a lathe, a drill press, a band saw, and a grinder, not to mention the myriad of smaller tools.

By merely printing the parts for one and assembling it, though, I don't need all that stuff*.  I don't even need the skill.  All I need is a working 3D printer and the raw materials necessary.


*Yes, I know I could make a zip gun by going to Home Depot and buying some stuff, and assembling it with hand tools, just go with me here.
