a) PLA vs. ABS: https://www.econologie.com/forums/l-impressi ... 12647.html
b) The 3D printer from the store is available at the presale for delivery in October 2013: https://www.econologie.com/shop/impriman ... p-511.html plus a launch promo (and always Franco de Port)

I just created a topic about installing the K8200 printer (a bit early, but this way we can prepare the ground)
