If you thought that 3D printing was neat, I just saw a news report that said the US Army has awarded research contracts to three universities for research into 4D printing!
What’s the 4th dimension? Time. They want things that will change their shape or properties over a controlled period of time. Interesting.
OK all you creative types - how could that be used in modelling? How about rolling stock that weathers itself over a scale period of time? Or maybe deciduous trees that sprout new leaves in the spring? I’m sure you can come up with better ideas than those!
Make them out of a thin and fairly light (not so it’s like model power’s metal train heavy) metal that rusts. Tin might work, and it’d dent like real ones too.
but then what happens in the fall? we need little bitty kids with little bitty rakes. lol
I forget what the fourth dimension is, but it is not time (my math teacher two years ago showed us a video on it), and there are 4D figures but none have been created the real world, considering that fact and the fact that we are now buying crappy jets (F-35s)that the Chinese copied from us instead of the state of the art ones (F-22 raptors) that we oringinal ordered along with the navy getting new crappy ships that don’t even work (LCSs) instead of ones that actually work (like frigates with updated systems), the government is going crazy.
They already invented that- it’s called the federal budget! It grows exponentially over very small periods of time, never to resume it’s original shape!!!LOL!!! Cedarwoodron
