Hey everyone I was just wondering if their are ways to add more Hardpoints to weapons and armor. I am aware of the talent in the Artisan talent tree in Force and Destiny but are there any other ways?

I think Triumphs rolled in the crafting check add HP too. Rules are in the FaD GM Kit, but I can't tell you for sure since I don't have it yet.

That only applies to lightsabers and its an optional rule

There is also the tinker talent in edge and age.

I know it´s a somewhat old thread but:

is there a limitation to the additional HP durring Lightsaberconstruction (like there is in the Guardian splat book with +1 HP only selectable once?)

Not per RAW, no.
