Cura Slicer settings for the Spray Jetboat

You will need to start from the standard quality profile and create some custom profiles.

You will need the following profiles. Customize them and then save them with the following names:

• Spray Solid:

  1. Quality - no real change here.

  2. Shell

     1. Wall Line Count - Set to 3 or 4. This will ensure concentric reinforcement around holes.

     2. Check Optimize Wall Printing Order

     3. Check Outer Before Inner Walls

     4. Check Filter Out Tiny Gaps

     5. Check Print Thin Walls

     6. Horizontal Expansion - You will have to test this on your machine but to get parts to slide together accurately this is where you will make that adjustment. For our Creality 10s Pro the value of -.04 seems to work.

     7. Hole horizontal expansion - Also for us we have it set to -.04 but you will need to experiment on your machine.

     8. Z seam Alignment - Set to user specified or sharpest corner.

     9. Seam Corner Preference - Set to smart hiding.

  3. Infill

     1. Infill Density - 100%

     2. Infill Pattern - My preference is concentric but feel free to experiment.

  4. Material

     1. We highly recommend that the majority of the models for this boat be printed with PetG. Follow the manufacturers recommendations for bed and nozzle temperature.

  5. Speed

     1. Well, how pretty do you want it? How much time do you have? As always, the slower the better. You will have to experiment with this one but we have general success at 50 mm/s. On very small parts we will bump this down to maybe 20.

  6. Travel

     1. Check Z Hop When Retracted

     2. Check Z Hop Height - we use .2 mm.

  7. Cooling

     1. It is our opinion that most of this model benefits from the stronger adhesion afforded by turning off print cooling giving the layers a few more seconds of bonding time.

  8. Support

     1. As a general rule, we include custom supports with each of the models. You can chose to use them or omit them and enable supports. Your call.

  9. Build Plate Adhesion - We tend to prefer using a raft.

  10. Mesh Fixes

      1. Check Union Overlapping Volumes

  11. Special Modes

      1. Surface Mode set to Normal

  12. Experimental

      1. No change here unless you would like to experiment with Tree supports. We find them superior in many cases to the standard support structure that Cura Auto Generates.

• Spray 25 percent.
