+ michaelmk. You’re absolutely wright about the health issues and raw materials of ABS/PLA!
I bought the ABS on Ebay for ~16EUR/.93kg, free shipping to EU, in the shop I’ve told you (not spoiler).
Building one as per http://www.vicious1.com/forum/topic/bavarian-700×900-ie-build/ , solid SS frame, 1.5mm thick SS tube for carriage. In ABS due to his tenacity and low price.
I put thick ABS juice on the Heated glass bed and, after first layer is printed, pause, and juice again over the piece(s). Strong adhesion printing and, when done, all looses under water from the glass :).
What a great machine!!
