support question please

[tom356 1]

One more question please..

So 2 times i tried to print this 4 hours each time, those are supports in the center and there is a cover on the top with a logo (never got that far with the top and logo)  , but when it starts to print on top of the supports it does not stick supports are to soft. Do i use support density to make the supports harder and what is roof support option for?

thank you

Does it have a perfectly flat roof?  If so maybe you don't need support.  PLA can bridge quite well.  What material are you printing with and what material are you using for support?  Are both materials PLA?

 

"roof support" is only if you have BAM (break away material) or PVA.  It creates a solid "roof" just under the model instead of an open support structure.
