Ultimaker 2 over extrusion

Recommended Posts

so when i print with my um2 it seems to slow down momentarily then spew out more plastic than normal.it causes bulges and unevenness any tip? also the plastic beads up and looks like little drip marks instead of one solid line. the extruder is not clicking or skipping.

the drip in stead of a 'noodle' can often be either the start of a blockage and/or a dirty end of nozzle - I always give mine a wipe when it is hot and then run a bit through - sometimes the noodles shoots off sideways so I wipe it a bit more until I get a nice straight down noodle.

warning - nozzle is hot :)

always worth doing the gr5 nuclear clean!

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
