Informatica What’s New in 3D Printing, Part IV: OctoPrint 5 Giugno 2016 admin This is the last article in a four-part series on the current state of 3D printing. In the first part, I gave an overall introduction to differences in 3D printing since I wrote my original articles on 3D printing three years ago. The second piece focused on advances in 3D printing hardware, and the third column covered 3D printing software. In that last article, I mentioned one particular piece of 3D printing software, OctoPrint, that I felt warranted its own article, so I am devoting this final article to how to set up and use OctoPrint.
