After milling the first parts I got hold of a piece of very nice plastic called POM, this turned out to be perfect! It mills three times as fast as aluminum and the mills stay perfectly sharp. It’s a hard plastic so the forces that can be applied to the part are high, I would definitively advice you to use this material.

For aluminum type 5083 the milling speed is typical 100mm/min for a 6mm endmill using a 1.5mm depth per pass and 2mm stepover. For POM this can be 200mm/min for a 6mm endmill using 3.0mm depth per pass and 2mm stepover. In a single pass 2 times the amount of material is removed with 2 times the speed.
