The least expensive plastic cnc machine is the MakerCAM by Eros. This machine has a build volume of just 40 x 40 x 40§, which is standard for this type of machine. It has been tested in the field and supports material such as wood and aluminum, using 0.010 and 0.015mm collets for 1/16§ and 1/8§ diameter cuts, respectively
This machine comes with a software package that is compatible with most popular CAD programs on the market today, including SolidWorks, ProE, SolidEdge, Catia, AutoCAD and so on. The software can be used to create virtual models of your product before it is actually manufactured. This saves you time because you don't have to wait until you get your parts made to test them out before beginning the production process; instead you can do it all before hand
The only drawback to this machine is its size: it's only about 6 inches thick so it won't work well for large projects where space might be at a premium or where your design may be too complex for the machine's small build volume (40x40x40).
