I have two resin printers (an old Proton and a Saturn 8k) and I've printed a fair number models, though no vehicles and it's been SO worth the money now that easy to print, less-brittle resins exist. The patreons I was subscribed to provided very good value per month too. I never got into tablestop stuff largely because of the cost but printing minis is wildly cheap after the initial setup costs--and it's not like you can't print other non-tabletop stuff (I use mine for other personal projects too). I can print a "space marine" and base him (I print my basic bases on an FDM printer) and it'll cost me somewhere in the ballpark of 15 cents vs, what, multiple dollars if I were buying from GW? I guess it does take a fair amount of DIY to learn the process and dealing with the resin itself is not exactly fun but I find that a worthwhile tradeoff.
