I’m printing with a Micro3D and using hatchbox PLA at 215 degrees celcius on blue tape. every time I print the PLA will not bond together, this causes the corners of my raft to warp up, long cracks in the print, and more often then not the print breaks when I take it off the bed. Also for some reason it adheres to the print bed just fine, it just doesn’t adhere to other PLA.
Pla should print OK all the way up to 230. after that the biggest difference is there are defects in the top of the print that indicate it was printed too hot. On top of that, high temps are better for layer adhesion. Honestly I would recommend you bump your PLA print temp to 200 to get stronger prints.
I don’t know if I can find print speed or layer height, i opened everything about it but I couldn’t find anything about layer height or print speed, also I forgot to mention, my first print worked fine and I have not changed any settings since then.
My prints become brittle above 190. At 200 they fall apart. Speed and extrusion play a bigger role in temperature and I go up to 260 when printing at over 120 MMS. Or when using a .8 nozzle. That all varies by printer and hot end tuning as well though.
I took the plastic covering off the print head, it doesn’t look good, but it seems to have solved the problem. I wonder if the print head was overheating?
