I had never heard of this guy on YT, but I really like his analytical approach to 3D printing problems. In this video he talks about bed adhesion issues, which I know have been a bit of a hot topic in this forum. He’s talking specifically about ABS, but I think most of his ideas are applicable to most filament types.
Thanks for the video. I never thought of using a metal deburring tool. You are right. There is a little something for everyone. The video did convince me to put printing ABS on the bottom of my list, however. I’m tempted to print that part in PLA as a point of comparison. Also, the upward air flow for the hotend cooling fan seems like an easy fix for manufacturers to implement. I wonder why they do not.
