Fusion3 F400-s printer is a great other than the rippled wall issue. I like the fact that it uses 1.75mm filament over the 3mm my airwolf uses. It allows for very fast and detailed parts. I'm constantly printing and making adjustments and for what I consider a rough-draft it does an accurate and detailed job. you may also visit https://replicatorwarehouse.com to have a great look on 3d printers.
