Maybe some of you already know about 3D printing but for those who don't, it's technology that gives you the opportunity to take your 3D model and have it reproduced as a real model for a reasonable fee. Imagine that you build a really cool looking model. You can convert it to a DXF format then have an engineering company that owns a 3D printer reproduce the model in actual 3D!\r\n\r\nAnyway, here is a link to a company that makes a really cool 3D printer. The printers start at about $26,000 but eventually the price will come down. In the mean time, there are engineering companies that use these printers to prototype their designs and many of them will print your model for a fee.\r\n\r\n3D printer \r\n\r\nThere are other companies that make these printers but this one is the best one I've found so far.
