3D printing is an innovative technology that lets you create a physical object from a digital model. It started in the 80’s under the name ‘rapid prototyping’ because this was the purpose of the technology: to prototype faster and cheaper. A lot’s changed since then, and today 3D printers offer amazing results and let you create anything you can imagine.

HOW DOES 3D PRINTING WORK?
3D printing is also called additive manufacturing, because unlike the traditional subtractive manufacturing, 3D printing doesn’t remove material, it adds it, layer after layer.
In order to print something, first you’ll need a 3D model of the object you want to create, which you can design in a 3D modeling program (CAD - Computer Aided Design), or use a 3D scanner to scan the object you want to print. There are also more simple options, like searching online on Youmagine.com for 3D models that have been created and shared by other people.
Once your design’s ready, all you need to do is import it into Cura, our open source print software. Cura will then turn your design into a gcode file ready to be printed as a physical object. Simply save your file to the supplied SD card and insert it into your Ultimaker and press print.
But how does the printer work? Although there are several 3D printing technologies, most of them create the object by laying down many successive thin layers of a material. Usually, desktop 3D printers use plastic filaments (1) which are fed into the printer by the feeder (2). The filament is melted in the print head (3) which extrudes the material onto the build plate (4) creating your object layer by layer. Once the printer starts printing, all you have to do is wait – it’s that easy.
Of course, when you become an advanced user, playing with the settings and tweaking your printer can lead you to even greater results.
