Could over extrusion cause stringing?

2

Absolutely

3

I was underextruding lol

Lol. I usually print at 195ish for 30mm/s in pla.

@Kura_kuea PLA print temperatures vary significantly per brand. I have a brand that prints at 185 and another that prints at 245.

@Adam_Steinmark wow 245? That’s some high temp PLA. Personally, I’ve never needed to print higher then 205 for the PLA brands I’ve used. But my printer is only reliable to about 35mm/s

7

I print at 40mm/s lol

Makergeeks Raptor PLA prints at 245 C and it prints beautifully on a 60 C bed. You can anneal it too but I’ve never tried with this brand. I print at ~50 mm/s max speed.

Cubes printed at 200C almost 0 stringing

What brand?

11

Atomic filament

Not all materials are suitable for all prints. If a print has too many print head lifts, that causes the filaments to retract, cooling the filament. This requires a slightly higher print head temperature to overcome that cooling. Not all software compensate for that. Some parts of a print without a lift may print fine, but the antlers and gaps in your prints require large lifts. Some stringing however should be expected with heated filament printers.

Stringing is normally caused by inadequate/no retraction during travel and/or temps too high for whatever material is being used. Some types of nylon will really want to string. Laywoo-D3 is also a notorious oozer. Overextrusion is extremely rare and would be one of the last things to look at.

@American_3D_Printing i was underextruding by 12% lol
