Having a great word processor won’t actually help you write the next bestselling novel. It might make it easier, but if you have a great novel in you, you could probably write it on paper towels with a crayon if you had to. A great 3D printer isn’t all you need to make great 3D prints. A lot depends on the model you start with and that software known as a slicer. You have several choices, and now you have one more: PathIO, a slicer sponsored by E3D, is out in beta. You can see a video about its features below.
The software has a few rough edges as you might expect from a beta. The slicer doesn’t feed Gcode to a printer directly, although Octoprint integration is forthcoming. Developers say they are focusing on the slicing engine which is totally new. According to their website, conventional slicers immediately cut a model into 2D slices and then decide how to realize each slice with respect to the shell and infill. Pathio works in 3D space and claims this has benefits for producing correct wall thickness and an increase in self-supporting geometries.
