Non planar layers
-
I am thinking about whether Delta has advantages printing rapid changing Z. Cartesian, CoreXY, Prusa, Ultimaker are designed to print layer after layer, whereas Delta prints Z with 3 actuators, this may be an advantage in the case of non-planar prints. Especially because some of the Z layer printers have backlash when changing from move-up to move-down and vice versa.

If David implements a 6 axis delta firmware, it will definitly be my next 3D printer! For now, I'm working on my 2 axis tilt bed in order to print portions of sphere (https://forum.duet3d.com/topic/10934/5-axis-3d-printing).

@NitroFreak Thanks for the videos. I can add diabase to the list (https://www.diabasemachines.com/home) they use Duet to achieve 5 axis but in a different way.
More generally if the slicer was able to output X Y Z U V W, where U, V and W are the other three axis (e.g. a tilting/rotating bed) then there is no change required or special kinematics. If you want X Y Z A B C where A,B and C are the tool head rotations, then also no issues in RRF.
What do you mean by "sinusoidal G2/G3 computing", in this case? surely to implement G2/G3 in this case you would need to define an arc center in each axis that the arc would move on?
In general tool path generation is going to be an issue. Not just the path in 5 or 6 axis but also a path that avoids collisions with parts of the object already printed.

This is really cool!
Wonder if it wil make it to the home/hobbyist scene. -
Did anyone tried this non-planar-Slic3r edition? I can't get something out of it, just messy G-Code...
-
@dc42... Do you think this can be implemented in Duet?
These movement, requires especial slicer and firmware?

It only needs special slicer. No changes in firmware needed
-
And that's what is exciting about it, as vs. prior efforts: It is available in a "mainstream" slicer.

I have found another video/guide

Before everyone gets the underwear too messed up with excitement...
There is a possible issue of this already having being patented by another company which might stop it being used freely............
-
@calvinx what company?
-
Cant remember, i will try to find the article again, i read it last night on one of the 3d printing blogs.
-
and how different is this than a hexapod with 5 axis?
sounds like someone is trying to patent the ESC key again

Are you sure this will stop us for non commercial use?
-
@fma I had the same idea, and a question: how about building a DIY 3D printer with patented technology and then printing and selling 3D printed parts in a shop. Is this allowed?
-
Good question ; I don't know...
-
-
@calvinx broken link?
-
No, the link works fine...
-
@peirof works for me
