@zeitverschreib Regarding #GhostBSD, that's more or less a FreeBSD "distribution" adding some automation installing and configuring a #desktop setup. Nothing you can't have with vanilla #FreeBSD just as well. The handbook has nice chapters guiding you doing this manual work.

I'd personally recommend going vanilla, you'll learn how the system works upfront, but I might be biased of course. With GhostBSD, you'll have a working desktop setup out of the box.

Can't say anything about 3D printing, never did that myself, except for one thing: FreeBSD vs GhostBSD will almost certainly make no difference regarding that.
