Rotating Tilted Nozzle - 3,4,5 axis conic slicer
-
just saw this implementation for conic slicing that works with multiple slicers, based on the idea from ZHAW: https://www.zhaw.ch/de/ueber-uns/aktuell/news/detailansicht-news/event-news/upgrade-fuer-den-3d-drucker-spart-zeit-und-stuetzmaterial/
It's by René K. Müller, aka xyzdims

Yes, very interesting! I would like to try to slice using a sphere, to be able to print a partial sphere...
-
Yes it looks ideally suited as a start point to print non planer top surfaces. I wonder if that would "just work" with slicer settings to control the extrusion direction for the top layer and then the script to modify the model.
-
One thing I found when I experimented with pseudo-5 axis printing (portions of sphere), is the extrusion needs to be adjusted along the path, as it is not constant width anymore... This is the tricky part I didn't solved.
-
Every time I see something like this I start to think about a delta printer, but with only 3 arms (one arm per carriage) with the heat sink moved above the effector and only the hot block/nozzle below.
I think 3 stepper motors and a lot of math (and a very precise build) would be a natural fit for this type of application.

@garyd9 I don't thing that would work, as there's nothing to stop the rotation of the effector. To control that, and the angle of the effector, you need to have each of the 6 arms independently controlled.

What a coincidence. I'm working on this on a Cartesian printer
-
This is quite interesting but would this not require a totally new slicer?
Also, unless the angle of the printhead can be changed, are you not going to increase surface roughness on flat surfaces ?
I guess the secret sauce also includes keeping everything stiff enough yet light. -

I worked a few weeks on a 6 axis delta printer, but finally went back to a CoreXY with 3 axis bed (like HeVort). A 3 axis delta is already difficult to calibrate, I can't imagine how hard a 6 axis would be!

I didn't follow the links, but it seems there are some options.
I think, I've seen a video of a real printer in action, not just an animation. The nozzle zoomed around the part in 45* angle. Just like @JayJay 's picture shows.
Wondering how good bed adhesion is, with no-squish nozzle-angle
