My oldest son has gotten into 3d printing at school and after seeing some of the things he has made, it has made me want to get into 3d printing and there are a bunch of things I would like to print such as some rc airplanes, a sporting shotgun case, misc. tools and such. I did my research and had my heart set on a Neptune 3 Plus which has a build size of 320x320x400. It hasn't been available for a number of months now and I'm looking at getting the Neptune 3 Max which has a build volume of 420x420x500. The max is more then I need and I'm wondering what exactly am I sacrificing by going to a larger printer. From my research it seems the bed can get deformed after prolonged use and on larger printers this is an issue and also on a larger printer the quality may not be as good. I have no experience here and am looking for the advice of people who have both large and midscale printers. What do you think? Thanks for any help you can give me.
