Alle 3D-printers (bijna) – (almost) all 3D-printers

Any idea how many 3D printer types there are? 3ders.org has a detailed list and price compare of all current 3D-printers.
And they are not even complete as the nicely engineered Czech Easy3Dmaker is missing, that we saw last week at Intermodellbau in Dortmund.
