10 strange uses for 3D printing

Given the costs of 3D printing, finding profitable logically causes users to explore unusual low competition/high value product niches. Until the 3D printing process economics becomes more capable/competitive at complex multi-material printing tasks - it's limited uses will remain in areas where other mfg. methods aren't more competitive - no matter how much hype the media puts out about a process whose limitations they clearly don't understand technically or economically.

Is this an example of Choux pastry? Or opening your mouth and putting your foot in it?

This may be off the subject a bit but, I was thinking of 3d printing for organisms the other day. Question; sugar (as a frame-work to grow tissue) has been tried, but what about chocolate? It melts at near body temp. and should be easy to print. Can it be implanted and then be quickly absorbed? Or would it cause rejection. Would any other material (cheap material) work? Would have to be sterile and chilled. I was thinking about implants for the eye, but this wouldn't be the right choice for a lot of reasons. Maybe for some other area of the body.

Let's remember that in order to copy anything in those 3D printers one first needs the material necessary for the copy: plasma,plastic, and chocolate may need to be ultra solid/melt proof at room temperature with instant refrigeration during & at the end of the printing process -within the 3D printer no less.

Currently for many it is unusual. I think that in the future of 3D technology will be used very widely for the benefit the mankind.
