Talk:P3Steel

May 3 2014 jcollasius I've build this printer with 3mm V4A steel instead of simple steel. It more than doubled the price of the material (steel 80€, V4A steel 180€) but corrosion isn't a problem anymore and i don't have to paint anything. A perfect add to this build would be a 3mm lasercut x-axis motor holder/idler and carriage!

October 12 2014 AndrewBCN I have built two versions of the P3Steel, the first one in 3mm stainless steel (€90 for the frame plus shipping) and the second one in 3mm S235 structural steel (€55 for the frame, plus shipping). There is actually no difference at all in the build process as I got to paint all the steel parts for both frames with inexpensive acrylic paint (see the wiki page I created for this P3Steel construction step). Although I am not using any anti-rust primer for the structural steel version, I don't really expect to have any problems with rust within the expected lifetime of these printers (10 years?). The prices I am quoting are for purchase here in Spain. I am not sure the extra €35 for the stainless steel frame are worth it, but it's nice to have the option anyway. I would say go with whatever suits you, the end result won't differ much.
