Shapeways is a big company and has certainly more powerful 3D printers that my makers, here, have not. I know now what they are able to do and what price they apply; Shapeways makes a very good work but expensive. And more, when I can find spare parts on the ATLAS website, I don't hesitate one second; cost is negligible! and I have, like everybody, to pay attention to my money!!!!
But thank you RDUN for your interesting comment. It's very useful and kind.
Have a good sunny sunday like here!
