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.
Note: Our stock gcodes provided with models are generated in Simplify3D. Some features can’t be achieved in Cura directly and need manual gcode merging.
Basic Cura profiles
Download profiles: 3dlabprint_Cura_4.6.zip
You may need to adjust profiles according to your printer.
- 3dlabprint_wing.curaprofile – basic standard PLA single-wall profile with internal structures
- 3dlabprint_lw_wing.curaprofile – basic LW-PLA single-wall profile with internal structures. 50% flow, no retractions, extra priming after travel moves
- 3dlabprint_lw_vase.curaprofile – LW-PLA vase mode profile for specific models (Bungee,…)
Note: Check PDF user guides for specific flow rates used with LW-PLA planes. Some parts require different density.
Slicing the internal structures
The common issue is, the Cura is not slicing the models with all the internal structures.
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.
