A CNC milling machine does the opposite of a 3D printer. A 3D printer starts with nothing and then builds up the model. A CNC milling machine starts with a full sheet of material and takes away material until the desired model is left. Of course, this implies a lot of waste, as often the model is only a fraction of the original sheet...
It works with a milling head that can mill away tiny layers from top to bottom of not too hard a material. When you mill away a tiny layer, the machine engraves, but if you mill away more material, you can create a 3D object.
The machine also works with a program for which you need an .stl file or an .svg file. So drawings are made either in 2D (as for the laser cutter) or in 3D (as for the 3D printer). Another disadvantage of this machine is that you can only take away material from the top side. You cannot take away material from the sides.
For this machine you'll always need to make an appointment. Take into account that this machine is not available on a daily basis and cannot be used for all projects. This will always be decided by the FabLab manager.
We would appreciate it if you would take into account the following guide lines:
When your (Inkscape) file is ready, you can pass in the FabLab by on a Friday between 9 and 11 am to have you file checked by the FabLab manager (do you want to be sure that he's present on that day, it's best to give us call on beforehand).
When the file is okay, an appointment is made for the milling itself (we usually try to plan this on a Friday after 10 am).
