In a most recent episode of The Big Bang Theory (S10,E09), Howard hauls out a miniature remote control toy he made of Stephen Hawking.


Although his wife and friends tried to convince him in was in poor taste, in the end Stephen Hawking (guest staring on the show) said how he would love to see a mini rc toy of himself.

When I saw the toy first appear on my screen, I immediately had my 3d printing brain working (and although I can’t confirm how it was actually made), it appears to have been in part 3d printed with technology, such as ZCorp, that utilizes ink jet heads containing ink and binders expelled onto thin layers of powder (similar to plaster). That would account for the mini Stephen, his accessories. and the wheelchair. While the rest of the toy could have been composed and retrofitted with additional mechanics, electrical components and wheels that were not 3d printed, in order to make if function!

If you are working on your own prototype, this is an excellent example as to how different methods, components and creativity can go into the creation of your idea.
