How stiff can you make the resin with those 3d printers ? Probably not as much as carbon fiber, but how does it hold against aluminium or fiberglass? Also, can you do composite fibreglass/resin with 3d printers ?

Surprisingly complicated question. Most hobbyist grade machines are low powered and can only cure resin with pretty poor mechanical properties. Industrial resin printers can actually make incredibly strong parts. The studio 1 can apparently print in Formlabs Tough 1500 which is a decent strength resin. It’s noticeably better than the average “ABS like”. Resin prints are also isotopic (unlike composites and fdm prints) which has a lot of advantages for mechanical parts. Asking if resin prints are strong is a bit like asking if metal parts are strong; it really depends on the metal or resin being used
My experience is the resin is very stiff but very brittle, but I haven't kept up with the latest resins.
