Re: Hacking the Xaar 128 printhead

aengel and wonko, thank you both for the references.

Re: Hacking the Xaar 128 printhead

Hi, I'm not intending to formulate my inks, but I'd like to avoid buying water based inks (whomever formulated them) if they will ruin a 200€ printhead.

Re: PowderMaker1 3DP printer

hello, this is my first post on this fantastic forum, and I take the chance to explain why I'm here. I'm operating a 3DS Projet 660 since a few years, so I have quite a bit hands on experience with this technology. Problem is that this printer (the one I own) sucks so much that I'm seriously conside...
