How to set model to print solid instead of hollow?

Thanks.
Needed to use customize, copy a profile, rename, close page and then select the new profile name and then amend the density.
All good now.
Appreciate the prompt replies.

Good to know. Sounds more complicated (several more steps) than just clicking plus. ??

It seems like it will be better to use and easier to save things and figure out which settings are which.
It’s nice how it shows the settings on the right panel.
I think it’s kind of annoying that you can’t just select one set of settings all at the same time. It has one set of settings for material and a separate selection for print settings.
And it really should say “duplicate” and not “copy” though.

This does not seem to be working now (Luban v. 4.1.4 - still generates fill when I set it to 100% infill density. Have some other options changed?

Maybe? I either slice with an old version of Luban or a different program altogether, but they’re constantly tinkering with the program. You can always follow @rojaljelly 's advice and up the number of top or bottom layers, or the wall thickness, until you’ve filled in the interior of your print.

Note, however, that 100% fill is only very rarely what you want to do, because part strength doesn’t increase linearly with the amount of infill. Unless you’re printing a part that something is going to be rubbing against long and hard enough to wear through the outside, 70-80% is going to give you pretty much the same strength for less plastic.
