Help Ultimaker highlighted my entire STL red.

[TerenceTung 0]

Hi everyone! I am very new to this app so the solution might be simple but I'll appreciate all the help I can get.

 

Basically I designed a simple calibration tool on Solidworks ---> saved as STL format ---> transferred to ultimaker cura 5.1.1 and after slicing, the app determined that the whole object will not print well (?) because it highlighted my entire model red.

 

Nevertheless I tried printing them in 2 different orientations (one vertical and one horizontal). In the horizontal position the print came out ugly while in the vertical orientation the print came out nicer but I was unable to separate the support without breaking my model.

 

May I have advice on altering my model to better suit 3D printing or settings that I can alter in Ultimaker Cura to produce a better print.

 

Settings on Ultimaker

- Dynamic Quality

- 30% infill 

- Support active

- Adhesion active 

- Infill type : Cubic Subdivision

It's fine.  In the Prepare view red means that an area needs support.  In the Preview red indicates "Outer Wall" extrusions.

I think it will come out much cleaner if you print it vertically.  It will be stronger if you print it laying down.

 

Use a pair of needlenose pliers to crush the shell of the support.  Just keep working at it.  An option I've been using lately is to lower the Support Flow and Support Interface Flow to 90% (the settings are in the Material section).

 

Solidworks, Inventor, and Fusion360 are very good at creating good STL's from parametric models.  Blender, TinkerCad, and some others need to be watched or the STL files will have errors.

 

Here is a Cura Project File.  My Ender 3 Pro is the printer.  I don't know your printer but when you open a Project File you will be prompted to Install a new printer, or if you happen to have an Ender 3 Pro the prompt will be to "Update" the printer.  If you "Update" then your printer would end up with my StartUp and Ending Gcode so "Install New".  Then you can slice it and see how I've butchered it what I've done.
