Slicing our models with Cura
Slicing with Cura is not as straightforward, as with Simplify3D and with the fast update period, usually breaking the compatibility with previous versions makes the management of projects virtually impossible. However it is possible to use this free slicing software in case you don’t want to buy the Simplify3D license for any reason. The following tips and tricks should help you on the way.
Slicing the internal structures
The common issue is, the Cura is not slicing the models with all the internal structures.
Here is a link to very basic Cura 4.4 profile that’s slicing the internal structures as supposed.
You may need to adjust this profile according to your printer.
Other than the standard settings be sure to set the following values:
- Infill density: 0
- Merged Meshes Overlap: 0
- Union Overlapping Volumes: False
- Remove Empty First Layers: False
- Surface Mode: Normal
- Spiralize Outer Contours: False
- Slicing Tolerance: Exclusive
Another great source of information about how to print the planes is following instructional video by Stefan from CNC kitchen:
Merging multiple Gcodes
You can also use different printing settings in various Z heights to simulate multiple processes in Simplify3D.
For example the wing joint of the wing part 3A on F4U needs to be printed with 2 perimeters, so it’s strong enough.
Kyle T. Currier from 3d LabPrint Pilots Association Facebook Group made an instructional video, on how to achieve this by using Cura, and manually merging multiple Gcodes with a text editor.
