I definitely made one of the better 3D printing purchases of my life buying a Printrbot Simple Metal for $599 assembled. From the first day I received it, it was solid and started printing without flaws. I’m going to give my opinion here first, but I’d also recommend reading the Make Magazine Review by Nick Parks. He knows his stuff and I value his opinion in the 3D printing world. With regard to my slicing setup, here’s what I’m running: Repetier – 0.95F (link to downloads page) Slic3r engine With the recommended print settings from the Printrbot Forum (see article) Octopi 3D print server (link to Octoprint.org) What I love about this little machine: Super Reliable – Since I’ve bought it, I have yet to have a failed print – seriously. Maybe that is because I’ve gotten pretty used to Repetier and and how to set these things up, but out of the gate, it just seems to be working flawlessly.
