Print base is deformed
PLA 1.75 mm. Nozzle 0.4 mm, extruder temperature set to 170°C, hotbed – 65°C. Layer thickness is 0.2 mm, print speed – 40 mm/s. Cooling is on, 30% infill. Just got PLA, used to print with ABS. All of print’s walls are getting deformed at the base.Responses
As was mentioned earlier, this is called “elephant foot”. You should lower the bed temperature gradually until you find the minimum setting sufficient to keep the print attached to the bed, but without causing this effect. Just don’t forget that when you print objects this small, plastic doesn’t get enough time to cool before the next layer is deposited. This has a multiplicative effect. First try printing 2-3 test cubes simultaneously, so there would be enough time for them to cool down. You’ll see much less melting. Then go about finding the right bed temperature.
