Beginner printer anons, op is looking for advice on beginner printers and if they can fulfill his purpose of action figure parts, joints and accessories.
That being said, anything is good enough to get started. They are tools, and 95% of getting good use out of a tool is the knowledge on how to use it. OP, i used the shittiest basic resin, on a $150 resin anycubic printer and could EASILY knock stuff out like this.
Now if you want precision stuff like what you see in this
>>11699197 video, yeah you'll want to buy the expensive specific type of resin and then tune your printer for that profile.
i cant speak for FDM printers as i only print in resin, but the A1mini looks absolutely fine for your first printer. The only advice i can really give for any 3d printing, is get the largest build plate you can afford, nothing else matters.
