Re: Printeresting?
This needs to be developed further, ASAP.
love the creativity.

Re: Printeresting?
There was a similar idea floating around two years ago, which went through a brief discussion on this forum:
viewtopic.php?f=2&t=4&p=37&hilit=curved+surface#p37
I think it's a great idea, although it's somewhat limited because the nozzle is designed to print flat. I would think that something like PETg, which has a habit of sticking to the nozzle, wouldn't do so well on an angled surface. But shallow angles are the worst for highlighting the stairstep effect of individual layers, and a little bit of non-planar surfacing could go a long way toward avoiding the need for many layers of filling and sanding.
This article is a much better presentation than the one from two years ago; in particular, they acknowledge the problem with nozzles designed to work on flat surfaces and have an answer for it. The MakerGear nozzle is better than the E3Dv6 for working at an angle, because the E3Dv6 has such a short cone with a huge overhang above it (which also makes it bad for printing PETg, which likes to stick to that overhang any chance it gets), but it still has a wide flat area around the nozzle opening. But the examples in the article were done using an E3Dv6, so the problem obviously isn't all that bad.
