Hi Shapesmiths, I am relatively new here but a big fan of 3D printing, this is one revolution I want in on at ground level. I came across these videos yesterday, while I presume many may have seen them I thought them worth sharing. I apologize if this has been shared already but I had to make sure everyone got to see these. Are we on the verge of 3D printed medicine, limbs, weapons, food, drugs, plants, viruses and perhaps one day even life? These 7 short presentations from TED discuss various current and future applications for 3D printing, Its as informative and inspiring as it is scary. TED Blog: 7 Talks on the wonders of 3D Printing Enjoy!
