Tilting the nozzle won’t solve all the cases and will further complicate the cases that it does not solve. Especially if that object is not entirely convex. So, the thing is that it’s relatively, sort of, vaguely, easy to figure out that kind of slicing… until you have to think about whether the tool head is going to hit any parts of any reasonably complex object when you actually build it. Posted in 3d Printer hacks, Software Development Tagged 3d printing, non-planar, slicing, universal slicer Post navigation And lest anyone think that non-planar slicing has no practical purpose, we previously covered ’s demonstration of how non-planar slicing can reliably create 90° overhangs with no supports. Such worries may not be an issue for most users at the moment, but it’s worth trying to get ahead of the curve on something like this. ![]() What’s the best way to create a toolpath for such a slice? After all, some slicing geometries are clearly better for the object, but can’t be accommodated by normal hot ends (that’s where a rotating, tilted nozzle comes in.) For example, when slicing a 20 mm cube with non-planar geometries, the resulting slices often look strange. This is a concept that raises other interesting questions, too. It’s all forward-thinking stuff, and certainly makes some compelling points in favor of a need for universal slicing a system capable of handling any geometry, with the freedom to process along any path or direction. There’s a video embedded below the page break that covers the main points. There are loads of pictures of a 20 mm cube being sliced with a variety of different geometries, so be sure to give it a look. works to re-imagine slicing itself, and shows off the results of slicing 3D models using non-planar geometries. However, as 3D printing becomes more complex and capable, this “flat planar slicing” approach will eventually become a limitation because a series of flat slices won’t necessarily the best way to treat all objects (nor all materials or toolheads, for that matter.) How a 20 mm cube looks when sliced in a cone-shaped plane. ![]() Take a 3D model, slice it into flat layers equal to layer height, and make a toolpath so the nozzle can create those layers one at a time. One may think that when it comes to 3D printing, slicing software is pretty much a solved problem. ![]()
