250 × 250 × 325 mm · 9 cans of 330 ml would stand on the plate

Medium — a larger envelope than 36% of the 132 machines here, and than 21% of the 56 powder bed fusion machines.

To scale beside a 330 ml can; drag to orbit. Small, medium and large are the thirds of the catalogue's machines with a stated envelope.
