# Extrusion stops during print

I changed the filament (PLA) in my Wanhao Duplicator I3+. I ended the first try to print when I saw that the 'lines' were too thin. I re-sliced with a higher temperature (195°C instead of 190°C). Now the print started without a problem but after about 25% no more filament came out of the extruder. What can be the reason and how can I resolve it?

The filament is from Vertex, grey. The object that I use to test is a 20 mm hollow cube from Thingiverse that I have used for the previous filament too.

I am not sure that this is a clogging problem since the print starts with no problems. It just stopped after 25%. When I started another print I was able to finish by increasing the temperature.

• You are probably experiencing clogging. Note that there are a few topics on that subject here on 3D Printing SE. Your question is a possible duplicate of I'm getting a prusa i3, if I have a nozzle clog, can I easily get rid of it by simply replacing the nozzle?; the accepted answer may be of interest for you.

• Can clogging happen during printing? The printed part is of good quality now that I use a higher temperature. It just stopped all of a sudden. Jun 9, 2018 at 11:52

• I will do a test with another object. The gcode is the same as before when the print finished correct. Jun 9, 2018 at 12:38
