Former electrical engineer, I became a dentist in 2011.  I designed and built my printer, Son of MegaMax, using surplus machine parts at the Milwaukee Makerspace. My newest printer design, Ultra MegaMax Dominator, is a coreXY machine with a 300x300x695 mm build envelope. Details here:

DesignSpark doesn't export to any other format, unless you want STL, OBJ, or a 2D DXF file, none of which seem very useful. DesignSpark is free. All you have to do is install it.
