On 5 of my printers I print hatchbox pla at 198 at 32mm/s, the others print at 187 for some reason same speed. I have always had poor inter layer bonding above 40mm/s. If I could speed up my printers I would, and I would make more money but I have not had the strength with any brand of PLA faster than 32. I have had many people tell me otherwise but The products I sell are all printed at 32.
