I have a jpeg of an image i want printed and am on a Mac. I have never done any 3D printing and would love to start... I dont have any 3d software. Can someone suggest the best easiest software to use so I can upload a file to get printed for Xmas? Am a prof photographer and can see huge growth in this area of printing, but just came across shapeways on twitter.... would love to get something done as a start for xmas and only have a jpeg at the moment Cut off day for xmas is 9th! eeek!
