This is a single wall print done on a BETA test Printrbot – lots of changes in the new model when compared to this. He did slow the print head down to accomodate his needs. Also, he prepared this file to test whether or not it was possible to force a RepRap to do a spiral…. it is. If you printed this part, it would have a seam line that gives away where the print head was when the Z axis moves up after each layer.
I am not showing it to highlight the spiral, although some may find that interesting. I just wanted to get another example out there of Printrbot’s print resolution potential. See the video below – it is long and the print is fairly slow – although the speed does increase toward the end. Great job, Brian!
