3D printers print 3D models, using a process called additive manufacturing or AM. This process uses computer control to lay successive layers of material to build a 3D model. br If you're in the market for a home 3D printer then there's a lot to consider. Do you want single colour, dual-colour or more? Do you need a 3D scanner? Do you place a premium on maximum quality or faster printing? Physical size and weight are issues, especially if space is at a premium, and then of course there's the small matter of price. br Here at you can find the best models.
