[Need help with settings? and or STL help.]

ORIGINALL, this was what I was trying for, and still prefer , but I cant seem to get it to print.  it breaks up past 50%

Oh and avoid cura 3.3.1 - it has a combing related bug that makes printing slower.  Stick to 3.2.1 or 3.4 when it comes out.

 

good to know. I am going to revert back to 3.2  (any guesstimates on when 3.4 will be out?)  I didnt realize there was a problem.

thanks, I am less worried about hitting a specific time, only the difference between what one guy said

 

".when I run that through the Makerbot Desktop slicer (0.3mm, 10% infill, 2 walls), I get 2hrs 46mins,"

 

its the difference in time that had me wondering if maybe I have incorrect settings.

 

I also realize that my STL file is throw together quicky and quite probably could be more efficient, but I am so new at this, I dont know how to "fix" the file to be faster.  Since I am using Cura, I thought maybe you smarter people would have insight.

Good morning,

 

So fair warning, I am totally new at this so, optimizing settings is way out of scope for me currently.

Short version is, I am trying to model something in TINKERCAD, and then 3d-print it.

 

I did everything I though I needed too, and Cura is reporting the print job will take 12 hours.  someone over at Thingyverse said he loaded my STL and its reporting only 2 hours.

 

so, without knowing more about what HE is doing, I am wondering if there is anything I am doing wrong (posted are my settings)

 

I am using Ultimaker 3.3 and using a Anet A8.    I wouldnt care too much if it was 2 vs 3 hours,  but 2 vers 12 thats a lot!

 

The design I am aiming for is to print an object that is   1" x 1" x 6"   kind of like a baking tray,  I want to print things inside the "tray" then pour in colored epoxy, and turn it on a lathe.

I have seen it done successfully with simple lines., but I would like to make more complex shapes.

 

so I have a few questions:

 

1 - are my settings ok?  and is it just because of what I did in the model?   

 

2 - is there a better way to "fill in the gaps?  I basically placed all the hearts and just dropped blocks around it to fill it in. then grouped them.

 

I am looking for any and all recommendation and help.
