PETG blob/hole defect? | 3D Printing | Page 1

Ignoring the overhang, what is this near the seam? This is PETG printed at 250C and I have a similar defect when I printed at 240C. I use the oven to dry PETG at around 150-200F and I don't near popping noises when the extruder is extruding so I don't think it's moisture. This only happens near seams or areas where a layer would end I think.

It appears that you are experiencing a phenomenon known as "zits" or "blobs." This is a common issue in 3D printing and can be caused by various factors, such as retraction settings, extrusion multiplier, or temperature fluctuations. Since you mentioned that this issue occurs near seams or layer transitions, it could be related to the way your slicer software handles the toolpath at these points.

I recommend checking your retraction settings, particularly the retraction distance and speed, to prevent oozing or stringing at the end of a line. You may also adjust the coasting or wipe settings in your slicer to help reduce these imperfections. Additionally, calibrating your extrusion multiplier and ensuring consistent filament flow can also help improve the overall print quality.

Lastly, make sure your printer's components are properly calibrated and in good condition. If the issue persists, consider experimenting with different print speeds or nozzle temperatures to find the optima...
