Since we got the printer for $32 less than list price, our unwritten goal is to try and spend less then $32 on upgrades, and see what quality we can get. Consider that this printer has a small build area (which we will maximize in the project) we will not be printing huge projects with this printer. But that's okay, because it makes sense that a small printer should print small items and print them with exceptional detail, so our objective is to be able to print highly detailed models, and articulated models or functional mechanical designs, so detailed print quality will be our benchmark for the print quality we are shooting for. On a printer this small, we're not really trying to go for warp speed printing as the goal, so our upgrades will be focused on detail, over speed. It is very likely that anything we do for improved detail will also help at higher speeds.
