If the prints coming from your printer look like somebody held a blowtorch to it keep reading.

All of your print appears to be ‘melted’, droopy and deformed. In 3D printing, you want for a smooth consistent print, not like the example in the image.

If your prints are suffering from these deformities, chances are you’re printing too hot or do not have sufficient cooling fans.

Printing cooler is the best advice we can give in this instance.

One, if not the most common problem we see in tech support is people printing way too hot. We’re not sure why this is; some presume hotter temperatures will improve flow rate. Sure, there’s a bit of a give here and there especially with thermistors not being the most accurate critters to begin with, but your first check should be – are you exceeding the print temperature recommendation for the filament used? We always suggest starting at the lowest point in the recommended range and work your way up in 5°C increments, if needed.

Check with the filament manufacturer’s documentation to make sure. Just because it says “PLA” on the box, it does not mean they will all print the same! There are hundreds, possibly thousands, of different types of PLA produced across the world.

Printing slower allows the heat building up in the printed object to dissipate before the next pass of the nozzle over the same area of the print.

Make sure your fans are working. You can try to switch to fans that are pushing more air or add more fans. Sometimes, using a desk fan as a workaround can help you until a more streamlined solution is found.

The ambient temperature is too high. If your printer is enclosed, open all doors, side panels or top covers to keep the ambient temperature down. Even the best fans are inefficient if all they’re doing is moving hot air around.
