275 × 275 × 420 mm · 16 cans of 330 ml would stand on the plate

Medium — a larger envelope than 52% of the 132 machines here, and than 45% 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.
