For a long time 3D printers relied on bed springs in each corner to level the bed and ensure a good first layer. However, most modern designs do away with them entirely. So can we safely remove them and rigidly mount the bed? In this video, I examine a range of 3D printers with and without springs to try and find an answer. I then do a before and after comparison on the Ender 3 with print tests.
