Non planar layers
-
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

I am not a lawyer, but I looked into the patend and saw it was abandoned in 2015, and there is an article https://smallbusiness.chron.com/patents-abandoned-65186.html explaining when a patent was abandoned, it can be used. A commecial produced product between abondent and new status active needs not to pay fees. But as I said, I have little patent knowledge.

@joergs5
good info but strange that the patent was only applied for in 2015 by auto desk.further investigation is required I think.
-
But AFAIK, a patent only prevents commercial use of something; I don't think it forbids someone to develop free sofware for personal use...
But I don't know if it is a problem for a university. It could also be a problem if Prusa Research implements something patented in their Slic3r fork...

I don't know the status of the Autodesk patent, but there is at least some prior art in 3D printing:
Some other prior art to the March 2015 Autodesk patent, specifically 3D printing:

Note that 2 of these links are not the same technic: they just distort a part, and can't slice a non planar part...
I plan to give a try to Bread.

An additional option and innovation to non planar printing: a nozzle which can rotate in all three axes so that the edges of the nozzle do not disturb the non-planar printing and the nozzle can be closer to the layer. Nozzle direction and hereby filament flowout of the nozzle is freely controllable.
