With current 3D Printing technology how many consumer products that we use in the would be able to be created through the use of 3D Printing. I think I found an answer. The limits are our imaginations. I went to an exhibition last yr by new designers. One of them had created a pair of high-heeled shoes, very elegant and intricate with flexible straps and solid sole and heel, she had printed them with a 3D printer in one working. Her concept was that a customers feet could be scanned with a 3D scanner and the shoe design adapted to exactly fit her feet, the shoes would be printed and delivered to her address.
