Scope

While building prototypes of concept model lip wing aircraft, presented on aliptera.com website, I run into cutting by hand complex curved shapes for the wings and fuselage.

The work was tedious at least, the model didn't look very good and it took forever to make.

I reached the conclusion I need a CNC machine to do the complex shapes I want.

It needs to be able to cut foam in 3D, making complex shapes. For this I think a loop of nichrome wire of 1/4 -1/2 inch diameter would do nicely.  To ensure rigidity of the loop some thicker gauge wire should be used.

I would like to use it also for cutting/engraving aluminum, wood, plexiglass.

Size: As big as possible. 4 x 3 x 3 ft would be nice.
