	3D Printers don't understand OpenSCAD or STL. They understand an extension of gcode, which is a decades-old language which sends direct instructions such as "heat to 100 degrees, move here, do this, move there, do that, cool down". In order to print a model you have to turn it into a series of 2D layers or "slices", using a program called a "slicer". Slicers output gcode. They need to be configured for a particular printer, with settings such as melting tempurature, bed size, fill style, overhang compensation, etc. Examples of slicing software:		3D Printers don't understand OpenSCAD or STL.

			[http://www.openscad.org/ OpenSCAD] is a programming language for describing 3D shapes. You write code on the left, and it renders your model on the right. Then you can export an STL file. It has many benefits:
			* free, open source, cross-platform
			* keyboard-centric, less mouse dragging
			* your models are deterministic
			* you can easily track your changes with git
			* the [https://en.wikibooks.org/wiki/OpenSCAD_User_Manual manual] is pretty straightforward
			* there's even a [http://openjscad.org/ browser javascript version]!

			But the software still has a long way to go. Some annoying things about OpenSCAD:
			* single-threaded rendering, so complex models take a long time
			* no persistent cache, so if you close it, you must render all over again
			* GUI blocks on rendering, so if your render takes too long you must kill it (save often)
