I want to print as fast as possible using Ultimaker 2. I have experience with ABS and PLA and I found that Ultimaker 2 is capable of making good quality prints using ABS at 150 mm/s but I was unlucky to reach the same quality using PLA at 150 mm/s. On the contrary, I found on the internet that a 3d printer can reach higher printing speeds when it uses PLA filaments. PLA is preferred for me due to purpose of the printed items. So my question is using what filament PLA or ABS Ultimaker 2 can print faster? And how?
