<P> Over the last several years numerous marketplaces specialized in 3D printing models have emerged . Some of the 3D printing marketplaces are combination of models sharing sites, with or without a built in e-com capability . Some of those platforms also offer 3D printing services on demand, software for model rendering and dynamic viewing of items, etc . 3D printing file sharing platforms include Shapeways, Pinshape, Thingiverse, TurboSquid, CGTrader, Threeding, MyMiniFactory, and GrabCAD . </P> <P> 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down or build from successive layers of material . </P> <P> 3D printing is a great way to create objects because you can create objects that you couldn't make otherwise without having complex expensive molds created or by having the objects made with multiple parts . A 3D printed part can be edited by simply editing the 3D model . That avoids having to do any additional tooling which can save time and money . 3D printing is great for testing out an idea without having to go through the production process which is great for getting a physical form of the person / company's idea </P> <P> In recent years, there has been an upsurge in the number of companies offering personalized 3D printed models of objects that have been scanned, designed in CAD software, and then printed to the customer's requirements . As previously mentioned, 3D models can be purchased from online marketplaces and printed by individuals or companies using commercially available 3D printers, enabling the home - production of objects such as spare parts, mathematical models, and even medical equipment . </P>

Where do you see a 3d representation of your model
